A proxy form or voting instruction form, as applicable, is included in the Meeting Materials.

If you vote by proxy, the individuals who are named on the proxy form will vote your shares for you, unless you appoint someone else to be your proxyholder.

If you appoint someone else, they must attend the online Meeting to vote your shares. See “How to Vote – Registered Shareholders” or “How to Vote – Non-Registered Shareholders” for additional information.

How to Attend the Online Meeting

We are holding our Meeting in a virtual only format, which will be conducted via live audio webcast. Shareholders will not be able to physically attend the Meeting.

Registered Shareholders (as defined below) and duly appointed proxyholders will be able to attend, participate and vote at the Meeting online at https://meetings.lumiconnect.com/400-793-639-180. Such persons may enter the Meeting by clicking “I have a login” and entering a username and the case sensitive password “gfl2026” before the start of the Meeting. The username for registered shareholders is the 15-digit control number located on the form of proxy you received. The username for duly appointed proxyholders will be provided to you by Computershare after the voting deadline has passed.

Guests, including Non-Registered Shareholders (as defined below) who have not duly appointed themselves as a proxyholder, can login to the Meeting by clicking “I am a guest” and completing the online form. Guests will be able to listen to the Meeting, but will not be able to vote at the Meeting. See “How to Vote – Registered Shareholders” or “How to Vote – Non-Registered Shareholders” for additional information on voting at the Meeting and additional information on appointing yourself as a proxyholder and registering with Computershare.

If you attend the Meeting, it is important that you are connected to the internet at all times during the Meeting in order to vote when balloting commences. You should ensure you have a strong, preferably high-speed, internet connection wherever you intend to participate in the Meeting. The Meeting will begin promptly at 10:00 a.m. (Eastern Time) on May 13, 2026, unless otherwise adjourned or postponed. Online check-in will begin one hour prior to the Meeting, at 9:00 a.m. (Eastern Time). You should allow ample time for online check-in procedures.

2 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

	Online:				Go to www.investorvote.com and follow the instructions on screen. You will need the 15-digit control number listed on your proxy. You do not need to return your proxy form if you vote on the Internet.
	By Mail or Courier:				Complete, sign and date the proxy form and return it in the envelope we have provided to 320 Bay Street, 14th Floor, Toronto, ON M5H 4A6, Attn: Proxy Department. Proxies must be returned in advance of the deadline. Please see the form of proxy for more information.
	By Telephone:				Call 1-866-732-8683 from a touch tone telephone and follow the instructions provided. You will need the 15-digit control number listed on your proxy. You do not need to return your proxy form if you vote by telephone.

If you vote by proxy, the individuals named on the proxy form will vote your shares for you unless you appoint someone else to be your proxyholder. You have the right to appoint another person of your choice who need not be a shareholder to represent you at the Meeting, (a “third-party proxyholder”) other than the persons designated in the proxy form. See below under “Appointment of a Third-Party as Proxy” for instructions.

Appointment of a Third-Party as Proxy

If you wish to appoint a third-party proxyholder to represent you and vote your shares at the Meeting, you MUST submit your form of proxy appointing that third-party proxyholder prior to registering such proxyholder with our transfer agent, Computershare. Registering your third-party proxyholder with Computershare is an additional step to be completed AFTER you have submitted your form of proxy.

How to Vote – Non-Registered Shareholders

You are a non-registered (or beneficial) shareholder (a “Non-Registered Shareholder”) if your shares are registered in the name of an intermediary such as a bank, trust company, securities dealer, trustee or administrator of self-administered RRSPs, RRIFs, RESPs and similar plans (each an “Intermediary”) or in the name of a depository (such as CDS Clearing and Depository Services Inc.) of which the Intermediary is a participant. If so, your shares will not be registered in your name on our records. Unless you instruct your Intermediary to vote in accordance with their request for voting instructions, they are generally prohibited from voting your shares, as shares should only be voted upon instructions of the beneficial holder. To vote by proxy before the Meeting, complete and return the enclosed form of proxy or voting instruction form in accordance with the instructions provided therein.

You may also vote your shares online through your nominee by following the instructions provided to you by them. Please read the instructions below regarding how to vote at, or attend, the Meeting under “Voting Online at the Meeting or Appointment of a Third-Party as Proxy”.

A Non-Registered Shareholder may revoke a voting instruction form or proxy which has been given to an Intermediary by written notice to the Intermediary or by submitting a voting instruction form or proxy bearing a later date in accordance with the applicable instructions. In order to ensure that an Intermediary acts upon a revocation of a proxy or voting instruction form, the written notice should be received by the Intermediary well in advance of the Meeting.

Exercise of Discretion of Proxyholders

You can choose to vote “For”, or “Withhold” or “Against”, as applicable, on the items listed on the proxy form or voting instruction form. When you sign the proxy form, you authorize the directors and/or officers of the Company who are named in the proxy form to vote your shares for you at the Meeting according to your instructions, unless you have appointed a third-party proxyholder to act as your proxy. If you return your proxy form and do not tell us how you want to vote your shares, your shares will be voted (i) FOR electing the nominee directors who are listed in the Circular; (ii) FOR appointing KPMG LLP (“KPMG”) as auditor of GFL and authorizing the Board to set the auditor’s remuneration; (iii) FOR the LTIP Renewal Resolution; (iv) FOR the DSU Plan Renewal Resolution; and (v) FOR the Say on Pay Advisory Resolution. If you do not specify how you want your shares voted, your proxyholder will vote your shares as they see fit on each item and on any other matter that may properly come before the Meeting.

If any further business is properly brought before the Meeting, it is intended that the persons appointed as proxyholder will vote on such other business matters in such manner as such persons then consider being proper.

TABLE OF CONTENTS

BUSINESS OF THE MEETING

The business of the Meeting will be the following items:

Receiving the Audited Annual Financial Statements

At the Meeting, shareholders will receive and consider the Company’s audited annual financial statements for the year ended December 31, 2025 (“Fiscal 2025”), including the auditor’s report thereon (the “2025 Financial Statements”). The 2025 Financial Statements, together with the management’s discussion and analysis thereon (the “2025 MD&A”), are available on the Company’s website at http://investors.gflenv.com and on SEDAR+ at http://www.sedarplus.ca, and the annual report on Form 40-F for the year ended December 31, 2025 (the “Annual Report”), which includes the 2025 Financial Statements and 2025 MD&A, is available under the Company’s profile on EDGAR at http://sec.gov.

Proposal 1 – Election of Directors

Our board of directors (the ‘‘Board”) currently consists of eight directors. The Board recommends that the eight persons identified in the section “Election of Directors” be elected to serve on the Company’s Board. Directors elected at the Meeting will serve, subject to our Articles (the “Articles”) and the Business Corporations Act (Ontario) (the “OBCA”), until the end of the next annual shareholder meeting or until their successors are elected or appointed. All of the individuals who have been nominated as directors are currently members of the Board.

Proposal 2 – Appointment of Auditor

The Board recommends that KPMG be appointed as auditor, and that the Board be authorized to fix the auditor’s remuneration. KPMG was first appointed as the Company’s auditor on August 20, 2021. The auditor will serve until the end of the next annual shareholder meeting or until a successor is appointed. Please see “Proposal 2 – Appointment of Independent Auditor” in this Circular for more information.

Information concerning the fees paid to the auditors of the Company for Fiscal 2025 and for the year ended December 31, 2024 (“Fiscal 2024”) may be found in the Company’s annual information form for the year ended December 31, 2025 (the “AIF”) under the section “Auditor Service Fees”. The AIF is available under the Company’s profile on SEDAR+ at http://www.sedarplus.ca, and the Annual Report, which includes the AIF, is available under the Company’s profile on EDGAR at http://sec.gov.

Proposal 3 – LTIP Renewal Resolution

Pursuant to the requirements of the Toronto Stock Exchange (“TSX”), the Company’s Omnibus Long-Term Incentive Plan (“LTIP”) must be presented to the shareholders for approval of the unallocated entitlements every three years. The existing LTIP was initially made effective on March 5, 2020 (the date of the closing of our IPO) and was last approved by the shareholders at the Company’s annual and special meeting held on May 17, 2023. As such, the Board has determined to seek shareholder approval for the renewal of the LTIP at the Meeting, as set out in the resolution in this Circular, which will also approve all unallocated options, rights or other entitlements under the LTIP and allow the Company to continue granting options, rights or other entitlements under the LTIP until May 13, 2029.

The Board has unanimously approved, subject to regulatory and shareholder approval, renewal of the LTIP and all unallocated securities under the LTIP.

Proposal 4 – DSU Plan Renewal Resolution

Pursuant to the requirements of the TSX, the Director Deferred Share Unit Plan (the “DSU Plan”) must be presented to the shareholders for approval of the unallocated entitlements every three years. The existing DSU Plan was initially made effective on March 5, 2020 and was last approved by the shareholders at the Company’s annual and special meeting held on May 17, 2023. As such, the Board has determined to seek shareholder approval for the renewal of the DSU Plan at the Meeting, as set out in the resolution in this Circular, which will also approve all unallocated deferred share units (“DSUs”) issuable pursuant to the DSU Plan and allow the Company to continue granting DSUs under the DSU Plan until May 13, 2029.

8 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

The Board has unanimously approved, subject to regulatory and shareholder approval, renewal of the DSU Plan, and all unallocated DSUs under the DSU Plan.

Proposal 5 – Say on Pay Advisory Resolution

The Board recommends that the Say on Pay Advisory Resolution be approved. Our Nomination, Governance and Compensation Committee (the “NGC Committee”) and the Board spend considerable time and effort overseeing the Company’s executive compensation program, and are satisfied that the policies and practices in place align the interests of our executive officers with those of our shareholders by tying a meaningful portion of compensation directly to the long-term value and growth of our business, and providing incentives that encourage growth balanced with appropriate levels of risk-taking and a strong pay-for-performance relationship. This executive compensation approach allows the Company to attract, retain and motivate high quality and high performing senior executives who will be incented to optimize business performance and enhance shareholder value. As this is an advisory vote, the results will not be binding upon the Board. However, the NGC Committee will review and analyze the voting results and, as appropriate, take into account such results when reviewing executive compensation policies and programs in the future.

Considering Other Business

We will consider any other business that may properly come before the Meeting. As of the date of this Circular, we are not aware of any changes to the items above or any other business to be considered at the Meeting. If there are changes or new items, your proxyholder can vote your shares on these items as they see fit. If any other matters properly come before the Meeting, it is the intention of the persons named in the form of proxy to vote in respect of those matters in accordance with their judgment.

TABLE OF CONTENTS

PROPOSAL 1 – ELECTION OF DIRECTORS

Our Articles provide that the Board shall consist of a minimum of three and a maximum of fifteen directors, with the actual number to be determined from time to time by the Board. Under the OBCA, a director may be removed with or without cause by a resolution passed by an ordinary majority of the votes cast by shareholders present in person or by proxy at a meeting and who are entitled to vote. The directors are elected by our shareholders at each annual meeting of shareholders, and all directors will hold office for a term expiring at the close of the next annual meeting or until their respective successors are elected or appointed. Between annual general meetings of our shareholders, the directors may appoint one or more additional directors, but the number of additional directors may not at any time exceed one-third of the number of current directors who were elected or appointed other than as additional directors. Certain aspects of the composition and functioning of our Board may be subject to the rights of the Investors under the Investor Rights Agreements (each as defined below), which, among other things, provide for certain director nomination rights. See “Investor Rights Agreements” below. Subject to such agreements, nominees for election as directors will be recommended to our Board by our NGC Committee in accordance with the provisions of applicable corporate law and the charter of our NGC Committee.

The Board unanimously recommends voting FOR the resolution to elect each of the eight nominated directors.

If you do not specify how you want your shares voted, the individuals named as proxyholders in the proxy form intend to cast the votes represented by proxy at the Meeting FOR the election as directors of each of the nominee directors listed in this Circular.

All nominees have established their eligibility and willingness to serve as directors. As of the date hereof, management of the Company does not expect that any of the nominees will be unable to serve as a director. However, if, for any reason, at the time of the Meeting, any of the nominees are unable to serve and unless otherwise specified, it is intended that the persons designated in the form of proxy will vote in their discretion for a substitute nominee or nominees.

Investor Rights Agreements

Effective at the closing of the IPO, we entered into investor rights agreements (the “Investor Rights Agreements”) with each of BC Partners Advisors L.P. (“BC Partners”), Ontario Teachers’ Pension Plan Board, (“Ontario Teachers”), Magny Cours Investment Pte Ltd. (“GIC”) and Patrick Dovigi, certain holding entities beneficially owned and controlled by Mr. Dovigi, his family members and discretionary trusts settled by family members of Mr. Dovigi (collectively, the “Dovigi Group”, and together with BC Partners, Ontario Teachers and GIC, the “Investors”) with respect to certain director nomination rights, governance matters and pre-emptive rights.

The following is a summary of the material attributes and characteristics of the Investor Rights Agreements. This summary is qualified in its entirety by reference to the provisions of the Investor Rights Agreements, which contain a complete statement of those attributes and characteristics. The Investor Rights Agreements are filed with the Canadian securities regulatory authorities and available on SEDAR+ at http://www.sedarplus.ca and with the U.S. Securities and Exchange Commission (“SEC”) on EDGAR at http://sec.gov.

The Investor Rights Agreements provide that BC Partners is entitled to nominate:

•

40% of our directors (rounding up to the nearest whole number) for so long as it beneficially owns or controls, directly or indirectly, at least 30% of the issued and outstanding shares;

•

30% of our directors (rounding up to the nearest whole number) for so long as it beneficially owns or controls, directly or indirectly, between 20% and 29.9% of the issued and outstanding shares;

Additionally, for so long as Mr. Dovigi is our Chief Executive Officer, he will be nominated as a director and upon election he is entitled to be the Chairman of our Board. Notwithstanding the foregoing, Mr. Dovigi is entitled to resign as the Chairman at any time. Upon Mr. Dovigi ceasing to be a director, or in the event he does not wish to be the Chairman, then the Chairman will be appointed by our Board.

Each of the Investors will not vote against or withhold their vote in respect of the other Investors’ nominees. Additionally, the Investor Rights Agreements provide that, for so long as BC Partners beneficially owns or controls, directly or indirectly, at least 15% of the issued and outstanding shares, the Dovigi Group is only permitted to vote the multiple voting shares that it holds in a manner consistent with the recommendation of the director nominees of BC Partners on our Board; provided that the Dovigi Group is not required to vote the multiple voting shares that it holds in a manner consistent with the recommendation of the director nominees of BC Partners on any matter that will disproportionally adversely affect the Dovigi Group’s economic or voting interest or is reasonably expected to disproportionally adversely affect the Dovigi Group’s economic or voting interest relative to BC Partners.

We have included certain advance notice provisions with respect to the election of our directors in our by-laws (the “Advance Notice Provisions”). Our Advance Notice Provisions are intended to: (i) facilitate orderly and efficient annual general meetings or, where the need arises, special meetings; (ii) ensure that all shareholders receive adequate notice of Board nominations and sufficient information with respect to all nominees; and (iii) allow shareholders to register an informed vote. Only persons who are nominated by shareholders in accordance with the Advance Notice Provisions are eligible for election as directors at any annual meeting of shareholders, or at any special meeting of shareholders if one of the purposes for which the special meeting was called was the election of directors.

Under the Advance Notice Provisions, a shareholder wishing to nominate a director is required to provide us notice, in the prescribed form, within the prescribed time periods. The Advance Notice Provisions provide requirements for proper written form of notice, which must include information relating to: (i) the person whom a shareholder proposes to nominate for election as a director (the “proposed nominee”), including but not limited to the number of securities beneficially owned, or controlled or directed, directly or indirectly, by the proposed nominee and relationship between the nominating shareholder and the person nominated as a director; and (ii) the shareholder who is providing the notice, and each beneficial owner, if any, on whose behalf the nomination is made (the “nominating shareholder”), including but not limited to the number of securities beneficially owned, or controlled or directed, directly or indirectly, by the nominating shareholder and its joint actors, if any, any interests in, or rights or obligations associated with any agreement which alters the person’s economic interest in a security of the Company or economic exposure to the Company, representation as to whether such person intends to deliver a proxy circular and/or form of proxy, and in each case, any other information that may be required by applicable laws. The prescribed time periods under

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 11

Majority Voting Policy

In accordance with the requirements of the Toronto Stock Exchange (the “TSX”), our Board has adopted a “Majority Voting Policy” to the effect that if a nominee for election as a director receives a greater number of votes “withheld” than votes “for”, the nominee will promptly tender their resignation following the meeting of shareholders at which the director was elected. Our NGC Committee will consider such resignation and make a recommendation to our Board whether or not to accept it. Our Board will promptly accept the resignation unless it determines, in consultation with our NGC Committee, that there are exceptional circumstances that should delay the acceptance of the resignation or justify rejecting it. Our Board will make its decision and announce it in a press release within 90 days following the meeting of our shareholders. A director who tenders a resignation pursuant to the Majority Voting Policy will not participate in any meeting of our Board or our NGC Committee at which the resignation is considered.

The market value of options reflects the value of in-the-money options as of March 31, 2026, which is calculated based on the difference between the closing price of the subordinate voting shares on the New York Stock Exchange (“NYSE”) on March 31, 2026 of US$41.72 ($58.15), and the exercise price of the option. The market value of the subordinate voting shares, multiple voting shares, performance share units (“PSUs”), restricted share units (“RSUs”) and DSUs are calculated based on the closing price per subordinate voting share of US$41.72 ($58.15) on the NYSE on March 31, 2026.

PROPOSAL 3 – LTIP RENEWAL RESOLUTION

On March 5, 2020, in connection with our IPO, we adopted the LTIP to provide different types of equity-based incentive awards to be granted to certain of our executive officers, employees and consultants, including our NEOs (collectively, the “eligible participants”), including options, PSUs and RSUs (collectively referred to herein as “awards”). Each award represents the right to receive subordinate voting shares, or in the case of PSUs and RSUs, subordinate voting shares or cash, in accordance with the terms of the LTIP. For more information on the material terms and conditions of our LTIP, see “Securities Authorized for Issuance Under Equity Compensation Plans – Equity Compensation Plan Information – Description of LTIP”.

Only subordinate voting shares are issuable under our LTIP, and the maximum number of subordinate voting shares reserved for issuance collectively under our LTIP, the DSU Plan and any other security-based compensation arrangement is 10% of the aggregate number of subordinate voting shares and multiple voting shares issued and outstanding from time to time. As of March 31, 2026, under the LTIP, there were 1,319,976 PSUs, 2,039,842 RSUs and 22,287,502 options outstanding, representing approximately 0.4%, 0.6% and 6.2%, respectively, of the aggregate number of our subordinate voting shares and multiple voting shares then issued and outstanding. As of March 31, 2026, 10,069,527 subordinate voting shares remained available for issuance under the LTIP and DSU Plan, together, representing approximately 2.8% of the aggregate number of our subordinate voting shares and multiple voting shares then issued and outstanding.

In accordance with the rules and policies of the TSX, director and shareholder approval is required every three years for all unallocated options, rights or other entitlements under a security based compensation arrangement that does not have a fixed maximum aggregate of securities issuable, such as the LTIP. The existing LTIP was initially made effective on March 5, 2020 (the date of the closing of our IPO) and was last approved by the shareholders at the Company’s annual and special meeting held on May 17, 2023. As the previous three-year term prescribed by the TSX will expire on May 17, 2026, the LTIP Renewal Resolution will be placed before our shareholders at the Meeting, as set out below, to renew the LTIP and approve the unallocated awards. This approval will be effective for three years from the date of the Meeting.

The full text of the LTIP Renewal Resolution is as follows:

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 23

TABLE OF CONTENTS

“Whereas:

The Board of Directors of GFL Environmental Inc. (the “Company”) adopted an omnibus long-term incentive plan (the “LTIP”) on March 5, 2020, which does not have a fixed maximum number of securities issuable;

The rules of the Toronto Stock Exchange (the “TSX”) provide that all unallocated options, rights or other entitlements under a compensation arrangement which does not have a fixed number of maximum securities issuable be approved every three years; and

The LTIP was last approved by the shareholders at the Company’s annual and special meeting held on May 17, 2023 and is effective for three years from the date of such meeting, and as such, the LTIP will expire on May 17, 2026;

RESOLVED THAT:

The renewal of the LTIP dated March 5, 2020 is hereby approved;

All unallocated options, rights or other entitlements under the LTIP be and are hereby approved;

The Company shall have the ability to continue granting options, rights or other entitlements under the LTIP until May 13, 2029, which is the date that is 3 years from the date of the shareholder meeting at which shareholder approval is being sought; and

Any officer or director of the Company be, and hereby is, authorized and empowered to make all such arrangements, to do and perform all such acts and things, and to execute and deliver all such documents, in the name and on behalf of the Company, or otherwise, as such officer and director deems desirable or necessary in order to effectuate fully the purposes of each and all of the foregoing resolutions.”

The Board unanimously recommends voting FOR the LTIP Renewal Resolution.

If you do not specify how you want your shares voted, the individuals named as proxyholders in the proxy form intend to cast the votes represented by proxy at the Meeting FOR the LTIP Renewal Resolution.

PROPOSAL 4 – DSU PLAN RENEWAL RESOLUTION

On March 5 2020, in connection with our IPO, our Board adopted the DSU Plan, which is a component of the Company’s long-term incentive compensation arrangements available for our non-employee directors. The DSU Plan provides such directors with the opportunity to receive a portion of their compensation in the form of DSUs, representing a unit equivalent in value to a subordinate voting share in accordance with the terms of the DSU Plan (based on the closing price of the subordinate voting shares on or about the day prior to the grant). DSUs are fully vested upon the date of grant and settled upon a director’s departure from service. The DSU Plan is administered by our Board, provided that the Board may, in its discretion, delegate its administrative powers under the DSU Plan to the NGC Committee. For more information on the material terms and conditions of the DSU Plan, see “Director Compensation – Deferred Share Unit Plan”.

The maximum number of subordinate voting shares reserved for issuance collectively under the DSU Plan, the LTIP and any other security-based compensation arrangement, is 10% of the aggregate number of subordinate voting shares and multiple voting shares issued and outstanding from time to time. As of March 31, 2026, under the DSU Plan, there were 152,053 DSUs outstanding, representing approximately 0.04% of the aggregate number of our

TABLE OF CONTENTS

subordinate voting shares and multiple voting shares then issued and outstanding. As of March 31, 2026, 10,069,527 subordinate voting shares remained available for issuance under the LTIP and DSU Plan, together, representing approximately 2.8% of the aggregate number of our subordinate voting shares and multiple voting shares then issued and outstanding.

In accordance with the rules and policies of the TSX, director and shareholder approval is required every three years for all unallocated entitlements under a security based compensation arrangement that does not have a fixed maximum aggregate of securities issuable, such as the DSU Plan. The existing DSU Plan was initially made effective on March 5, 2020 and was last approved by the shareholders at the Company’s annual and special meeting held on May 17, 2023. As the previous three-year term prescribed by the TSX will expire on May 17, 2026, the DSU Plan Renewal Resolution will be placed before our shareholders at the Meeting, as set out below, to renew the DSU Plan, and approve the unallocated DSUs. This approval will be effective for three years from the date of the Meeting. Previously allocated DSUs will be unaffected by the approval or disapproval of the DSU Plan Renewal Resolution. The full text of the DSU Plan Renewal Resolution is as follows:

“Whereas:

RESOLVED THAT:

The renewal of the DSU Plan dated March 5, 2020 is hereby approved;

All unallocated deferred share units under the DSU Plan be and are hereby approved;

The Company shall have the ability to continue granting deferred share units under the DSU Plan until May 13, 2029, which is the date that is 3 years from the date of the shareholder meeting at which shareholder approval is being sought; and

PROPOSAL 5 – ADVISORY VOTE ON EXECUTIVE COMPENSATION

Under the guidance of our NGC Committee, which is responsible for administering and reviewing our executive compensation program, we have designed an executive compensation program intended to attract, retain and motivate high quality and high

performing senior executives. Our compensation program aligns the interests of our executive officers with those of our shareholders by tying a meaningful portion of compensation directly to the long-term value and growth of our business, and providing incentives that encourage growth balanced with appropriate levels of risk-taking and a strong pay-for- performance relationship.

Our executive compensation program includes a mix of base salary, annual non-equity incentives and equity-based or equity-like compensation currently consisting of stock options, PSUs and/or RSUs. We believe that our base salaries and annual non-equity incentives are currently effective at attracting and retaining executives, while providing motivation and rewards for the achievement of key business and financial objectives. Further, our equity-based incentives, which may include multi-year and/or performance-based vesting and laddered exercise prices, are intended to tie executive compensation to the performance of our subordinate voting shares, our business and the long-term interests of shareholders, while discouraging inappropriate risk-taking.

As described in the section “Compensation Discussion and Analysis – Independent Compensation Consultant and Peer Group Comparisons”, our NGC Committee has retained an independent compensation consultant to assist with its review of compensation for our NEOs and other related matters. The NGC Committee, in consultation with the independent compensation consultant, established, among other things, a peer group to be used as a reference for executive compensation decisions.

The Board is also committed to maintaining an ongoing engagement process with our shareholders by adopting effective measures to receive shareholder feedback. In this light, the Board wishes to offer our shareholders the opportunity to cast an advisory non-binding vote on the Company’s approach to executive compensation, which is described in further detail under the section “Compensation Discussion and Analysis”. Accordingly, shareholders are being asked to consider and, if deemed appropriate, to approve the following Say on Pay Advisory Resolution:

“RESOLVED, on an advisory basis and not to diminish the role and responsibilities of the Board, that the shareholders of the Company approve the approach to executive compensation disclosed in the management information circular made available in advance of the annual meeting of shareholders.”

As this is an advisory vote, the results will not be binding upon the Board. However, the NGC Committee will review and analyze the voting results and, as appropriate, take into account such results when reviewing executive compensation policies and programs in the future. Results of the vote will be disclosed in the report of voting results and related press release to be publicly filed shortly after the Meeting.

The Board unanimously recommends voting FOR the Say on Pay Advisory Resolution.

If you do not specify how you want your shares voted, the individuals named as proxyholders in the proxy form intend to cast the votes represented by proxy at the Meeting FOR the Say on Pay Advisory Resolution.

DIRECTOR COMPENSATION

Our compensation program for our directors is designed to attract and retain committed and qualified directors that possess the range and depth of skills and experience required for our Board. Our Board, through our NGC Committee, is responsible for reviewing and approving any changes to the directors’ compensation arrangements. In consideration for serving on our Board, directors are paid an annual retainer which may, at our Board’s discretion, be paid in cash or in some combination of cash and DSUs. We also reimburse our directors for all reasonable out-of-pocket travel expenses incurred in connection with attendance at meetings of the Board. Approximately 60% of our non-employee directors’ retainer is paid in the form of DSUs and approximately 40% is paid in cash, subject to any director’s election to receive a greater proportion in DSUs.

Pursuant to the Investor Rights Agreements, we do not compensate a director who is a partner, principal, member of, or employee of an Investor or any of its Affiliates (as defined in the Investor Rights Agreements) for his or her service on our Board or on our committees. In addition, as an employee of GFL, Mr. Dovigi does not receive any additional compensation for serving as a director on our Board.

The following table outlines our director compensation program for our non-employee directors in Fiscal 2025.

Deferred Share Unit Plan

DSUs granted to participants under the DSU Plan vest on the date of grant and can only be redeemed following the participant’s death, disability, resignation or retirement from our Board, or if such director becomes an employee of the Company, upon their termination (with or without cause) as a director.

DSUs may be settled in cash, subordinate voting shares or both, in accordance with the terms of the DSU Plan and the grant agreement. The Board, in its sole discretion, may cancel all or a portion of a participant’s DSUs as a result of the participant’s termination for cause. Except as specifically provided in a grant agreement approved by our Board, DSUs granted under the DSU Plan are generally not assignable or transferable, whether voluntarily, involuntarily, by operation of law or otherwise, other than by will or the laws of descent and distribution. The

maximum number of subordinate voting shares that may be: (i) issued to insiders of the Company within any one-year period; and (ii) issuable to insiders of the Company at any time, in each case, under all of the Company’s security-based compensation arrangements (or under the DSU Plan alone), cannot exceed 10% of the aggregate number of shares issued and outstanding from time to time. The DSU Plan does not include a maximum that may be issued to a participant. The DSU Plan provides that appropriate adjustments, if any, will be made by the Board in connection with a reclassification, reorganization or other change of our shares, share split or consolidation, distribution, merger or amalgamation, in the shares issuable or amounts payable to preclude a dilution or enlargement of the benefits under the DSU Plan. In the event that a director receives subordinate voting shares in satisfaction of an award during a black-out period, such director is not entitled to sell or otherwise dispose of such subordinate voting shares until the black-out period has expired. No financial assistance is provided by the Company to participants in connection with the DSU Plan.

In the event of a change of control of the Company, the Board has the authority to take all necessary steps to ensure the protection of the rights of the participants under the DSU Plan, including ensuring that the Company or any entity which is or would be the successor to the Company or which may issue securities in exchange for the subordinate voting shares upon the change of control will assume each outstanding DSU, or provide each participant with new, replacement or amended DSUs which will continue on similar terms and conditions following the change of control as provided in the DSU Plan.

The Board may make such other provisions for the protection of the rights of the participants under the DSU Plan as it deems appropriate; however, no participant shall be entitled to receive payment for, or in respect of, any DSU on or before the director’s death, disability, resignation or retirement from the Board or if such director becomes an employee of the Company, before the director’s subsequent termination as a director (with or without cause).

The Board may, in its sole discretion, amend, suspend or terminate the DSU Plan at any time, or from time to time, amend the terms and conditions of the DSU Plan or of any DSUs granted under the DSU Plan and any grant agreement relating thereto, provided that such amendment (i) does not materially adversely affect the rights of a participant as permitted by the terms of the DSU Plan without the participant’s written consent unless such amendment is necessary to comply with law and (ii) is in compliance with applicable law and subject to any regulatory approvals including, where required, the approval of the TSX and NYSE.

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis (“CD&A”) provides a detailed description of our executive compensation philosophy and objectives and the principal elements of our executive compensation program and policies. This CD&A is intended to provide additional context and background for the compensation earned by and awarded to our executive officers for Fiscal 2025, including, in particular, the following NEOs:

•

Patrick Dovigi, President and Chief Executive Officer;

•

Luke Pelosi, Executive Vice President and Chief Financial Officer;

•

Billy Soffera, Executive Vice President and Chief Operating Officer;

•

Mindy Gilbert, Executive Vice President and Chief Legal Officer; and

•

Elizabeth Joy Grahek, Executive Vice President, Strategic Initiatives.

Executive Summary

We operate a dynamic and growing business that is a leader in its industry. Our ability to continue to grow our business and achieve our financial performance is tied to our ability to attract, retain and motivate a highly talented, skilled and experienced team of executive officers. Since our IPO, the price of our subordinate voting shares on the NYSE, our Adjusted EBITDA and our Adjusted Free Cash Flow have more than doubled. This growth was driven in part by our executive team’s ability to execute on our strategy to grow the business, including organically and through acquisitions.

We believe that to continue accomplishing our objectives, we must have an executive compensation program that aligns the interests of our executive officers with those of our shareholders by tying a meaningful portion of compensation directly to the long-term value and growth of our business, and providing incentives that encourage growth balanced with appropriate levels of risk-taking and a strong pay-for-performance relationship. Accordingly, our compensation policies and practices are designed to:

•

attract, retain and motivate high quality and high performing senior executives;

•

align the interests of our senior executives with shareholders and the Company as a whole;

•

establish clear corporate and individual performance objectives; and

•

discourage the taking of inappropriate or excessive risks.

In furthering these objectives, our compensation plan includes a mix of base salary, annual non-equity incentives and equity-based or equity-like compensation which consists of stock options, PSUs and RSUs.

In designing our executive compensation program, the NGC Committee also takes into account the compensation philosophies and structures of private equity funds, which are in our experience more likely competitors for attracting executive-level employees. The executive compensation programs offered by private equity funds typically include significant long-term incentive compensation elements designed to align management with the long-term performance of the business.

We believe that our base salaries and annual non-equity incentives are currently effective at attracting and retaining executives, while providing motivation and rewards for the achievement of key business and financial objectives. Further, our equity-based incentives, which may include multi-year and/or performance-based vesting and laddered exercise prices,

30 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

are intended to tie executive compensation to the performance of our subordinate voting shares, our business and the long-term interests of shareholders, while discouraging inappropriate risk-taking.

In addition to our compensation mix, we have also implemented a number of compensation policies and practices to further such objectives, which are highlighted in the table below.

Policies and Practices	Objectives	Results
Pay-for-Performance	A significant percentage of executive officer total compensation is performance-based to encourage and reward contributions to our financial objectives.	☑ For 2025, 97% of the compensation received by our NEOs (excluding All Other Compensation) was performance-based. See “Principal Elements of Compensation”. Over the last three years, on average 93% of the compensation received by our NEOs (excluding All Other Compensation) was performance-based.
Independent Compensation Consultant	Obtain advice from independent compensation consultant for executive compensation-related matters.	☑ Pearl Meyer & Partners, LLC (“Pearl Meyer”) assists the NGC Committee with its review of compensation for the NEOs and other compensation-related matters. See “Independent Compensation Consultant and Peer Group Comparisons”.
Peer Group Benchmarking	Peer group to benchmark executive compensation decisions.	☑ With the assistance of Pearl Meyer, our NGC Committee uses a well-structured peer group as a reference for executive compensation decisions. See “Independent Compensation Consultant and Peer Group Comparisons”.
Minimum Share Ownership Guidelines	Share ownership guidelines for our directors and NEOs emphasize the importance of equity ownership for our directors and NEOs and reinforce alignment with our shareholders’ interests.	☑ Each of our NEOs and eligible directors meets or exceeds the minimum share ownership thresholds set out in our share ownership guidelines. See “Other Compensation Policies – Share Ownership Guidelines”.
Risk Assessment of Compensation Programs	Regularly review and assess the Company’s compensation program to guard against excessive risk-taking.	☑ The NGC Committee annually reviews our compensation programs to ensure that they do not encourage excessive or inappropriate risk-taking. See “Other Compensation Policies – Compensation Risk Assessment”.
Clawback Policy	Clawback policy to recover incentive compensation in the event of a restatement.	☑ Our Clawback Policy requires recovery of certain incentive compensation if it is earned based on financial statements that become subject to a restatement. See “Other Compensation Policies – Clawback Policy”.
Anti-Hedging Policy	Certain insiders are prohibited from purchasing financial instruments that hedge or offset any decrease in market value of equity securities granted as compensation.	☑ Our Insider Trading Policy prohibits our executive officers and directors from purchasing financial instruments that hedge or offset (or are designed to hedge or offset) any decrease in market value of equity securities granted as compensation or held, directly or indirectly, by the executive officer or director. See “Other Compensation Policies – Anti-Hedging Policy”.

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 31

TABLE OF CONTENTS

As circumstances require, we evaluate our compensation philosophy, policies and practices, which includes the periodic review of our compensation program and the mix of components made available to our executive team. As part of this review process, we are guided by the philosophy and objectives outlined above, as well as other factors which may become relevant, such as the evolution and growth of our business and the cost of replacing or enhancing our talent composition as our needs may require.

Approach to Compensation and Role of the NGC Committee

The NGC Committee is responsible for annually reviewing and making recommendations to the Chief Executive Officer and the Board regarding compensation for our directors and named executive officers. The NGC Committee reviews the compensation program to assess whether it continues to meet its objectives and remains aligned with industry best practices. In making its recommendations, the NGC Committee considers: (i) data and analyses prepared by our independent compensation consultant, Pearl Meyer, based on our current and prior performance (as described further below); (ii) the historical pay and the appropriateness of that compensation compared to the compensation in the peer group; (iii) recommendations of our Chief Executive Officer for executives other than himself; and (iv) its own judgment as to an appropriate level of compensation for a company of our size, financial performance and growth profile.

Further responsibilities of the NGC Committee, as set out in its written charter, include assisting our Board in fulfilling its governance and oversight responsibilities with respect to, among other matters, our human resources, succession planning, and compensation policies and practices, and reviewing objectives, evaluating performance in light of such objectives, and ensuring that our policies and practices are consistent with the objectives of our compensation program and aligned with our goals.

For more information on the composition of our NGC Committee, the independence of its members, and its responsibilities, powers and operation, see “Corporate Governance – Nomination, Governance and Compensation Committee”. The members of our NGC Committee have direct experience that is relevant to their responsibilities regarding executive compensation. For more information on the skills and experience of the NGC Committee’s members that enable it to make decisions on the suitability of the Company’s compensation policies and practices, see “Proposal 1 – Election of Directors – Description of Proposed Director Nominees” and “Corporate Governance – Mandate of our Board of Directors”.

Shareholder Engagement

Throughout 2025, certain independent directors engaged in targeted discussions with shareholders regarding the Company’s executive compensation program. Based on this shareholder engagement and the NGC Committee’s review of benchmarking and other information, the Board believes that our executive compensation program continues to align executive pay with performance and the interests of long-term GFL shareholders.

Independent Compensation Consultant and Peer Group Comparisons

The NGC Committee has retained Pearl Meyer, an independent compensation consultant, to assist with its review of compensation for the NEOs and other compensation-related matters.

The NGC Committee supervises the work done by Pearl Meyer. While Pearl Meyer provides data and analyses and makes recommendations to the NGC Committee on the form and amount of compensation, our Chief Executive Officer is ultimately responsible for approving our senior executive compensation (for senior executives other than himself and the other NEOs) and our Board, on the recommendation of the NGC Committee, is responsible for approving our Chief Executive Officer’s compensation and the compensation of the other NEOs.

32 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

Since 2020, Pearl Meyer has advised the NGC Committee on a variety of subjects, including compensation plan design and trends, performance-driven incentives, peer group benchmarking and other related executive compensation matters. Pearl Meyer reports directly to the NGC Committee, participates in meetings as requested and communicates with the NGC Committee Chair as necessary.

In 2023, in consultation with Pearl Meyer, the NGC Committee updated the peer group used as a reference for executive compensation decisions, which was initially adopted in 2020. Criteria used for establishing the peer group include (i) organization size, with financial characteristics and growth profile such as revenue, EBITDA, EBITDA margin or enterprise value similar to those of the Company, (ii) country of domicile, including Canada and the United States, and (iii) industry, including companies in the environmental, facilities and diversified support services, transportation, oil and gas equipment and services, distribution and construction materials industries. Due to limited peers in Canada, the industry criteria are broader for the Canadian companies. The peer group, set out below, is reviewed by the NGC Committee from time to time.

Advanced Drainage Systems, Inc.	Canadian Pacific Kansas City Limited	Clean Harbors, Inc.	Fortive Corporation
Herc Holdings Inc.	Iron Mountain Inc.	J.B. Hunt Transport Services, Inc.	Republic Services, Inc.
Ryder System, Inc.	Summit Materials, Inc.	TFI International Inc.	TransDigm Group Incorporated
United Rentals, Inc.	W.W. Grainger, Inc.	Waste Connections, Inc.	Waste Management, Inc.
WSP Global Inc.

Commencing in 2023, the NGC Committee engaged Pearl Meyer to assist it in designing a long-term equity incentive plan for our NEOs (the “New LTI Plan”). Throughout 2024 and 2025, Pearl Meyer continued to assist the NGC Committee in developing and implementing the New LTI Plan. See “Long-Term Equity Incentives”.

The aggregate fees paid to Pearl Meyer for executive-compensation related services and all other services provided during Fiscal 2025 and Fiscal 2024 were as follows:

Type of Fees	Fiscal 2025			Fiscal 2024
Executive Compensation-Related Fees		$	228,490		$	38,416
All Other Fees			–			–
Total Fees Paid		$	228,490		$	38,416

Principal Elements of Compensation

The compensation of our executive officers currently includes three major elements: (i) base salary, (ii) non-equity incentives, consisting of an annual cash bonus and (iii) long-term equity incentives, consisting of stock options, RSUs, PSUs and other equity-based awards as may be granted from time to time generally under the LTIP. Perquisites and personal benefits are not a significant element of compensation for our executive officers, other than our Chief Executive Officer. See “Executive Compensation and Related Tables – Summary Compensation Table” below.

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 33

TABLE OF CONTENTS

Base Salaries

Base salary is provided as a fixed source of compensation for our executive officers. Base salaries are determined on an individual basis taking into account the scope of the executive officer’s responsibilities and their prior experience. Base salaries are reviewed annually by our Board and may be increased based on the executive officer’s success in meeting or exceeding individual objectives, as well as to maintain market competitiveness. In addition, base salaries can be adjusted as warranted throughout the year to reflect promotions or other changes in the scope or breadth of an executive officer’s role or responsibilities.

Non-Equity Incentives

Non-equity incentives are designed to motivate our executive officers to meet our strategic business and financial objectives generally and our annual financial performance targets in particular. Such incentives are based on objective financial and non-financial targets set at the beginning of each financial year at the discretion of the NGC Committee, which may vary from year to year. Non-equity incentives are determined by our Board on the recommendation of the NGC Committee.

At the beginning of each year, the NGC Committee adopts performance targets for the fiscal year. Our actual performance for the applicable year is then compared to (i) target levels of Adjusted EBITDA1, weighted at 40%, (ii) target levels of Adjusted Free Cash Flow1, weighted at 40% and (iii) overall achievement of non-financial objectives, weighted at 20%.

Adjusted EBITDA and Adjusted Free Cash Flow are metrics that are reported by us in our earnings releases and filings with the SEC and applicable securities commissions or similar regulatory authorities in Canada. The NGC Committee chose these measures of performance because they are widely used by investors as valuation measures and because the targeted goals encourage improving free cash flow and return on invested capital.

Adjusted EBITDA is calculated by adding and deducting, as applicable from EBITDA, certain expenses, costs, charges or benefits incurred in such period which in management’s view are either not indicative of underlying business performance or impact the ability to assess the operating performance of our business, including: (a) (gain) loss on foreign exchange, (b) (gain) loss on sale of property and equipment, (c) change in value on Call Option, (d) share of net (income) loss of investments accounted for using the equity method, (e) share-based payments, (f) (gain) loss on divestiture, (g) transaction costs, (h) acquisition, rebranding and other integration costs (included in cost of sales related to acquisition activity), (i) Founder/CEO remuneration and (j) other. EBITDA represents, for the applicable period, net income (loss) from continuing operations plus (a) interest and other finance costs, plus (b) depreciation and amortization of property and equipment, landfill assets and intangible assets, plus (less) (c) the provision (recovery) for income taxes, in each case to the extent deducted or added to/from net income (loss) from continuing operations.

Adjusted Free Cash Flow represents Adjusted Cash Flows from Operating Activities adjusted for (a) proceeds on disposal of assets and other, (b) purchase of property and equipment and (c) incremental growth investments. Adjusted Cash Flows from Operating Activities represents cash flows from operating activities adjusted for (a) operating cash flows from discontinued operations, (b) incremental cash flow adjustment related to corporate costs attributable to discontinued operations, (c) transaction costs, (d) acquisition, rebranding and other

Adjusted EBITDA and Adjusted Free Cash Flow are measures that are not calculated in accordance with International Financial Reporting Standards (“IFRS”). For a reconciliation of Adjusted EBITDA and Adjusted Free Cash Flow to the comparable measures calculated in accordance with IFRS, please refer to our earnings releases and other filings with the SEC and applicable securities commissions or similar regulatory authorities in Canada.

integration costs, (e) Founder/CEO remuneration, (f) cash payments related to GFL Environmental Services transition services agreement, (g) cash taxes related to divestitures, (h) cash interest paid on early termination of long-term debt and (i) distribution received from joint ventures.

Changes to these measures year over year for purposes of establishing performance targets are subject to the approval of the NGC Committee, and are reviewed on an annual basis. The NGC Committee does not engage any third party in its review and analysis of these measures.

Targets for Adjusted EBITDA and Adjusted Free Cash Flow are determined by applying a percentage, or factor, to the internal stretch goals established for our operations. Our cumulative performance relative to target is calculated as a weighted average and treated as a multiplier. The multiplier is applied to the target payout so that if we achieved 100% of our targets, the participants would receive 100% of their annual target incentives, provided that if we achieved less than 95% of our targets, participants would receive 0% of their annual target incentives. Participants may earn up to a maximum of 200% of their annual target incentives if we achieved at least 105% of our targets. The NGC Committee reviews the targeted performance goals and multipliers on an annual basis, including for purposes of comparing such goals and multipliers with those adopted by the peer group referred to above.

The NGC Committee may adjust the targeted performance goals during the year if an acquisition, divestiture, significant new contract or extraordinary event results in a significant impact on the goals. For Fiscal 2025, the NGC Committee adjusted the targets for Adjusted EBITDA and Adjusted Free Cash Flow to reflect the impact of certain acquisitions and divestitures completed during the year.

The table below sets out the targets for Adjusted EBITDA and Adjusted Free Cash Flow for Fiscal 2025, the actual results achieved and the corresponding non-equity incentive payout.

Performance Measure	Target	Achieved Results	Multiplier		Weighting		Payout (% of target incentive)
Adjusted EBITDA	$1,890.1	$1,985.0		2.000		40.0%		80.0%
Adjusted Free Cash Flow	$695.8	$756.0		2.000		40.0%		80.0%
Non-Financial Achievements	See below	See below		2.000		20.0%		40.0%
Total								200.0%

Each year, the NGC Committee also reviews the Company’s non-financial achievements during the fiscal year, which, in Fiscal 2025, included the following:

•

Reduced our total recordable incident rate, an industry-standard measure of health and safety performance;

•

Significantly decreased voluntary employee turnover rates;

•

Increased volumes of recycled materials at our facilities in support of our sustainability goals under our Sustainability Action Plan;

•

Reduced Scope 1 and Scope 2 greenhouse gas emissions in support of our goal of achieving a 30% reduction by 2030;

•

Increased our beneficial use of biogas from our landfills in support of our goal of doubling the use of such biogas by 2030;

•

Purchased renewable energy certificates to offset 90% of our Scope 2 greenhouse gas emissions;

•

Achieved our goal relating to the purchase of compressed natural gas (“CNG”) fueled collection vehicles;

•

•

Released our second Climate Report, prepared in accordance with the recommendations of the Task Force on Climate-related Financial Disclosures;

•

Submitted our third CDP Climate Change Questionnaire, widely recognized as one of the most robust climate-related disclosure questionnaires, and improved our score to A-, the second-highest score achievable;

•

Continued to partner with our communities through our Full Circle Project, including donating more than $4 million to local charities;

•

Held our fifth annual Greenlight Innovation Workshop; and

•

Achieved our goal of certifying 10 nature conservation projects at our sites by 2025 in partnership with Wildlife Habitat Council.

The annual non-equity incentive amounts awarded to our NEOs for Fiscal 2025 are set forth in the “Summary Compensation Table” below.

Transaction Bonuses

From time to time, our NEOs may be recognized for their contributions to material transactions undertaken by the Company in the form of transaction bonuses. In 2025, the Company completed the divestiture of the Environmental Services business at an enterprise value of $8.0 billion. The transaction allowed the Company to materially delever its balance sheet, accelerating its path to an investment grade credit rating, while also allowing the Company to participate in continued value creation through its retained equity interest in the business. In recognition of their contribution to the successful completion of the divestiture, the NEOs were awarded transaction bonuses. The transaction bonuses were determined by a committee of independent directors, with the assistance of Pearl Meyer, based on a review of precedent transactions. See “Summary Compensation Table” below for more details.

Long-Term Equity Incentives

Long-term incentive compensation awards align the interests of our executive officers with the interests of our shareholders by awarding pay-for-performance that reflects the long-term interests of our shareholders, supports the achievement of our performance objectives and encourages an appropriate level of risk-taking, while also cultivating longer term retention. We believe that equity-based compensation awards help to motivate our executive officers to achieve our strategic business and financial objectives.

The NGC Committee is responsible for administering the Company’s LTIP and, in particular, recommending to the Board the allocations of long-term incentive compensation awards for the NEOs. Each year, the NGC Committee, after consultation with the Chief Executive Officer, assesses the Company’s performance and the performance of each of the NEOs during the most recently completed fiscal year. Based on the NGC Committee’s review of such performance and with a focus on maintaining a competitive market level of compensation, each NEO receives a grant under the LTIP.

Historically we have granted options and RSUs to NEOs as part of their long-term incentive compensation. In 2025, the NGC Committee, with the assistance of Pearl Meyer, finalized the New LTI Plan, which included the design of a PSU plan (the “PSU Plan”). The New LTI Plan was approved by the Board in November 2025. Pursuant to the New LTI Plan, NEOs will receive a

mix of PSUs and RSUs as part of their long-term incentive compensation. The Board retains the discretion to grant stock options to NEOs in future periods.

Restricted Share Units

RSUs vest ratably over a three-year period following the first anniversary of the date of grant in increments of 33.3% per year, subject to the participant’s continued employment. When cash dividends are paid on the subordinate voting shares, holders of RSUs receive additional units (“Dividend Share Units”) as of the dividend payment date. Dividend Share Units are subject to the same vesting provisions as the RSUs. Upon vesting, the RSUs will be settled in either cash or subordinate voting shares, at the election of the Board.

Performance Share Units

In developing the PSU Plan, the NGC Committee considered the extensive analysis prepared by Pearl Meyer, the compensation programs offered by the peer group referred to above, matters raised with the independent directors during their shareholder engagement initiatives and the current competitive environment for top talent in a sector attracting private equity interest. The PSU Plan is designed to encourage and reward the building of long-term shareholder value through successful strategy execution and further enhance the link between the Company’s performance and NEO compensation.

Payouts in connection with the awards granted under the PSU Plan are contingent upon the Company achieving certain performance targets over a three-year performance period. Performance targets for PSUs are recommended by management of the Company, subject to the approval of the NGC Committee. The NGC Committee seeks to establish rigorous but reasonable performance targets based on appropriate assumptions and projections. At the end of the performance period for each grant, the Company will deliver, at the election of the Board, a number of subordinate voting shares or its cash equivalent, calculated based on the Company’s performance against such targets.

Each participant may earn up to a maximum of 225% of their target number of PSUs based on achievement of two metrics: a return on invested capital (“ROIC”) improvement goal, weighted at 50%, and an Adjusted Free Cash Flow per share growth goal, weighted at 50%. The NGC Committee selected the ROIC and Adjusted Free Cash Flow per share metrics because it believes they are critical drivers of sustained value creation over the longer term and align the interests of NEOs with those of shareholders. The PSU Plan also includes a Total Shareholder Return (“TSR”) modifier, such that if a participant achieves the maximum number of PSUs, and the Company’s TSR performance during the applicable period is above the 70th percentile or below the 30th percentile, measured against the S&P Canada LargeMidCap Growth Index, awards will be adjusted upwards or downwards, respectively, by 25 basis points, resulting in a maximum potential payment of 250% of target awards. The NGC Committee selected the S&P Canada LargeMidCap Growth Index based on the number of companies within the index, the relative revenue and market capitalization of the peer group and the industry mix.

The table below sets out the minimum required achievement of ROIC improvement and Adjusted Free Cash Flow per share growth performance measures and the corresponding potential payouts under the PSU Plan.

2025 Long Term Incentive Grants

Commencing in 2023, the NGC Committee engaged Pearl Meyer to assist it in designing the New LTI Plan, including the PSU Plan. While this longer-term plan was being developed, the Board adopted the 2023 retention plan for the NEOs (the “2023 Retention Plan”). The 2023 Retention Plan was intended to act as a transition plan to ensure management continuity and the successful delivery of near-term objectives, while the NGC Committee worked on a more performance-based long-term incentive approach.

Pursuant to the 2023 Retention Plan, during a four-year period that commenced with fiscal 2023, each NEO was entitled to receive an annual retention award in the form of RSUs that vested immediately on the date of grant. The initial awards under the 2023 Retention Plan were granted in September 2023, with subsequent awards granted in March and September of each year and final awards granted in March and September of 2025. The 2026 awards issuable under the 2023 Retention Plan were effectively canceled as a result of the 2025 Grants (defined below).

In November 2025, on the recommendation of the NGC Committee, the Board approved the granting of PSUs and RSUs to the NEOs (the “2025 Grants”). The 2025 Grants consisted of: (a) a transition grant of RSUs (“Transition Grant 1”), (b) a second transition grant of RSUs and PSUs (“Transition Grant 2”) based on a split of 75% PSUs and 25% RSUs (assuming PSU performance at target), and (c) a new grant of RSUs and PSUs (“New LTI Grant”) under the New LTI Plan based on a split of 75% PSUs and 25% RSUs (assuming PSU performance at target).

Transition Grant 1 vests ratably on March 1, 2026 and September 1, 2026 (in the case of Mr. Dovigi, in full on February 1, 2026) and is intended to replace the balance of the awards that were to be granted under the 2023 Retention Plan. Transition Grant 2 PSUs cover an abbreviated two-year performance period (January 1, 2025 to December 31, 2026) with the Transition Grant 2 RSUs cliff vesting in full on March 1, 2027 (in the case of Mr. Dovigi, February 1, 2027). The New LTI Grant PSUs cover a three-year performance period (January 1, 2025 to December 1, 2027) with the New LTI Grant RSUs vesting ratably over a three-year period commencing on March 1, 2026 (in the case of Mr. Dovigi, February 1, 2026).

The 2025 Grants are intended to assist in the transition from the 2023 Retention Plan, which consisted of RSU grants only, towards the mix of RSUs and PSUs contemplated by the New LTI Plan, without creating a gap in the long-term incentive compensation for the NEOs. By way of illustration, the table below sets out the values and vesting schedule for the 2025 Grants for Mr. Dovigi.(1)

PSUs are calculated at target. The value of the awards at the time of vesting will depend on the Company’s achievement of ROIC improvement and Adjusted Free Cash Flow per share growth performance, as well as the value of the subordinate voting shares at such time. PSUs granted pursuant to the New LTI Grants are subject to the performance criteria described above under “Performance Share Units”. In order to account for the abbreviated performance period for the Transition Grant 2 PSUs, modified ROIC improvement performance measures derived from the Company’s budget for the applicable period were adopted.

(3)

The total Value Granted of US$75,000,000 differs from the value of the Share-Based Awards for 2025 presented in the Summary Compensation Table for the following reasons: (a) the value of PSUs as shown above is based on the market value of the subordinate voting shares at the date of the grant, instead of the grant date fair value of the PSUs calculated using the Monte Carlo simulation and (b) amounts presented above are in U.S. dollars.

(4)

The 2027 vesting total will also include one third of an RSU grant to be made in 2026, such that the aggregate value of awards vesting in 2027 will be US$20,000,000.

(5)

The 2028 vesting total will also include one third of the 2026 RSU grant and one third of an RSU grant to be made in 2027, such that the aggregate value of awards vesting in 2028 will be US$20,000,000.

Other Compensation Policies

Share Ownership Guidelines

The Board recognizes the importance of aligning the financial interests of the Company’s directors and NEOs with the interests of the Company’s shareholders while also enabling such directors and executive officers to share in the long-term growth and success of the Company. Accordingly, the Board maintains share ownership guidelines for directors and NEOs. The current minimum ownership guidelines are as follows:

•

for the Chief Executive Officer, five times such individual’s annual base salary;

•

for each other NEO, three times such individual’s annual base salary; and

•

for each director, subject to certain exceptions, three times such individual’s annual cash board retainer.

Directors and NEOs will be deemed to have satisfied the applicable ownership guidelines if the fair market value of all equity interests, which include our multiple voting shares, subordinate voting shares and the “in-the-money” value of vested equity based entitlements and unvested time-based equity based entitlements under our equity based incentive plans (as such plans may be adopted from time to time), held by them equals or exceeds the relevant multiple of their then current annual base salary or cash portion of their board retainer, as applicable, as calculated on the first trading day of each fiscal year using the closing price of the subordinate voting shares of the Company on the last trading day of the prior fiscal year. The guidelines state that the directors and NEOs should be able to achieve these guidelines within five years of the later of: (i) our IPO, and (ii) the director’s or NEO’s date of appointment.

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 39

TABLE OF CONTENTS

Any director that is prohibited from receiving compensation from the Company as a result of his or her employer’s policies may be exempt from these guidelines. Additionally, the NGC Committee will consider, and may approve, an alternate share ownership guideline for a director or executive officer who, due to unique financial circumstances, would incur a hardship by complying with these guidelines.

For Fiscal 2025, each of our Chief Executive Officer and our other NEOs exceeded the minimum share ownership requirements set out in the guidelines as follows:

Name	Ownership Guidelines	Share Ownership (Multiple of Annual Base Salary)(1)
Patrick Dovigi	5 x annual base salary	375x
Luke Pelosi	3 x annual base salary	43x
Billy Soffera	3 x annual base salary	9x
Mindy Gilbert	3 x annual base salary	25x
Elizabeth Joy Grahek	3 x annual base salary	15x

(1)

The multiple is determined by dividing the NEO’s share ownership value by the amount of the NEO’s annual base salary. The share ownership value is calculated based on the vested in-the-money value of options and the number of securities held by each NEO as of December 31, 2025, including RSUs, subordinate voting shares and multiple voting shares, with each security being valued at the closing price of the subordinate voting shares on the NYSE on December 31, 2025 of US$42.95 ($58.87).

Each of our directors who receives an annual cash retainer for his or her position on our Board also exceeds the minimum share ownership requirements set out in the guidelines.

Anti-Hedging Policy

Pursuant to our insider trading policy (the “Insider Trading Policy”), our executive officers and directors are prohibited from purchasing financial instruments, such as prepaid variable forward contracts, equity swaps, collars or units of exchange funds, that hedge or offset (or are designed to hedge or offset) any decrease in market value of equity securities granted as compensation or held, directly or indirectly, by the executive officer or director.

Clawback Policy

Our Board has established a clawback policy (the “Clawback Policy”) to encourage sound financial reporting and increase individual accountability. The key terms of the Clawback Policy, which was amended in 2023 to conform to updated NYSE listing standards, are as follows:

•

the policy applies to all current and former named executive officers (as defined in Canadian Securities laws) and persons who serve as executive officers (as defined in Rule 10D-1(d) under the Securities Exchange Act of 1934, as amended) of the Company (the “Covered Executive Officers”), as well as additional employees designated by the NGC Committee from time to time (the “Other Designated Employees” and, together with the Covered Executive Officers, the “Covered Officers”);

•

the policy applies to all short- and long-term compensation arrangements if the amount, payment and/or vesting of such arrangement is calculated based in whole or in part on the attainment of one or more measures determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, or any measures derived in whole or in part from such measures, and received by a person: (i) after beginning service as a Covered Executive Officer or being designated as an Other Designated Employee, (ii) who served as a Covered

40 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

Executive Officer or was designated as an Other Designated Employee at any time during the performance period for that compensation, (iii) while the Company has a class of its securities listed on a national securities exchange or association and (iv) during the applicable Three Year Period (as defined below) (collectively, the “Incentive Compensation”);

•

the policy is triggered by an accounting restatement to correct the Company’s material noncompliance with any financial reporting requirement under applicable securities laws, including restatements that correct an error in previously issued financial statements (i) that is material to the previously issued financial statements or (ii) that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (a “Restatement”);

•

for purposes of the policy, “Three Year Period” means, with respect to a Restatement, the three completed fiscal years immediately preceding the date that the Board, a committee of the Board, or the officer or officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare such Restatement, or, if earlier, the date on which a court, regulator or other legally authorized body directs the Company to prepare such Restatement. The “Three Year Period” also includes any transition period (that results from a change in the Company’s fiscal year) within or immediately following the three completed fiscal years identified in the preceding sentence. However, a transition period between the last day of the Company’s previous fiscal year end and the first day of its new fiscal year that comprises a period of nine to 12 months shall be deemed a completed fiscal year.

•

if a Restatement occurs, the Company shall, subject to the exceptions set out in the policy, recover from the Covered Officer, reasonably promptly, the amount by which their Incentive Compensation for the relevant period exceeded the lower payment that would have been made based on the Restatement, as determined on a pre-tax basis in accordance with Section 10D of the Securities Exchange Act of 1934, as amended, Rule 10D-1 promulgated thereunder, all applicable rules or regulations adopted by any national securities exchange or association on which the Company’s shares are listed and any other applicable laws.

Compensation Risk Assessment

Our NGC Committee is responsible for ensuring that our compensation policies and practices reflect an appropriate balance of risk and reward consistent with our risk profile while motivating performance consistent with our growth objectives. As part of the review of the compensation paid to our executive officers, our NGC Committee considers the potential risks associated with the structure and design of our various compensation policies and practices.

To date, we have not identified any risks arising from our compensation policies and practices that are reasonably likely to have a material adverse effect on the Company. To identify and mitigate compensation policies and practices that could encourage an executive officer to take inappropriate or excessive risks, we have adopted the following policies and practices:

•

executive rewards are subject to approval of our Board;

•

all directors and employees are subject to the Company’s Code of Ethics, which has been adopted by our Board and provides for, among other things, a commitment to carry out all business activities ethically and honestly and to avoid even the appearance of improper behavior;

•

a significant portion of compensation provided to our executive officers is contingent on performance;

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 41

TABLE OF CONTENTS

•

minimum share ownership guidelines requiring NEOs and directors to own equity interests in the Company, which ensures that long-term interests of such executive officers and directors are aligned with those of our shareholders;

•

adoption of the Clawback Policy to allow for recovery of certain incentive compensation if it is earned based on financial statements that become subject to a restatement;

•

our Insider Trading Policy prohibits our executive officers and directors from purchasing financial instruments that hedge or offset (or are designed to hedge or offset) any decrease in market value of equity securities granted as compensation or held, directly or indirectly, by the executive officer or director; and

•

fully independent NGC Committee, which retains an independent compensation consultant that provided no other services to the Company in Fiscal 2025.

Termination and Change of Control Benefits

We have employment agreements and equity incentive award agreements with each of our executive officers, which provide for certain payments and restrictions upon termination or change of control of the Company. Such terms are generally set forth below and a table indicating incremental payments that would have been made to our NEOs upon the occurrence of certain events is set out under “Executive Compensation and Related Tables” below.

Termination Without Cause, Resignation for Good Reason or Termination Surrounding Change of Control

If Mr. Dovigi’s employment were to be terminated by us without cause or he resigned for good reason, he would be entitled a payment equal to three times his base salary and bonus earned for the fiscal year immediately prior to the year of termination, payable in substantially equal installments during the 12-month period following termination, a prorated target bonus in respect of the year in which his termination occurs and participation in the benefit plans and use of vehicle until the end of the 12-month period following termination.

If the employment of Mr. Pelosi, Mr. Soffera, Ms. Gilbert or Ms. Grahek were to be terminated by us without cause or such executive resigned for good reason (outside of the 12 months following a change of control), he or she would be entitled to a payment equal to two times his or her base salary and average bonus received in the previous two fiscal years immediately prior to the year of termination payable in equal installments in the two years following termination (collectively, the “Termination Payments”), a prorated target bonus in respect of the year in which his or her termination occurs and participation in the benefit plans until the earlier of 18 months or comparable coverage is secured through alternate employment. If the employment of Mr. Pelosi, Mr. Soffera, Ms. Gilbert or Ms. Grahek were to be terminated by us without cause or such executive resigned for good reason within 12 months following a change of control, he or she would be entitled to a lump sum payment of the Termination Payments within 60 days of termination, a prorated target bonus in respect of the year in which his or her termination occurs and participation in the benefit plans until the earlier of 18 months or comparable coverage is secured through alternate employment.

If Mr. Dovigi’s employment were to be terminated by us without cause or he resigned for good reason, all of Mr. Dovigi’s IPO Options would remain exercisable until the earlier of the third anniversary of his termination and the end of the term of the options, all of his 2021 Options (as defined below) would continue to vest and expire on the earlier of the fifth anniversary of the date such options vest and June 29, 2031 and any other long-term

42 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

incentive awards held by Mr. Dovigi would vest and become immediately exercisable (assuming PSU performance at target).

If the employment of Mr. Pelosi, Mr. Soffera, Ms. Gilbert or Ms. Grahek were to be terminated by us without cause or such executive resigned for good reason, all IPO Options held by the NEO would remain exercisable until the earlier of the third anniversary of his or her termination and the end of the term of the options, all of the NEO’s unvested 2021 Options would continue to vest and expire on the earlier of the third anniversary of the date such options vest and June 29, 2031 and any other long-term incentive awards held by the NEO would vest and become immediately exercisable (assuming PSU performance at target).

If a change of control occurs, each NEO’s 2021 Options would vest and become immediately exercisable until the end of the respective terms thereof and all other long-term incentive awards held by the NEO would vest and become immediately exercisable (assuming PSU performance at target).

Termination With Cause or Resignation Without Good Reason

If any of our NEOs were to resign without good reason or if such executive’s employment were to be terminated by us for cause, all unvested equity awards would terminate as of the date of his or her resignation or termination for cause.

Termination Upon Death or Disability

In the event of a termination upon death or disability, Mr. Dovigi’s employment agreement provides that we will continue to maintain the benefit plans for the benefit of him and his dependents for a period of at least 12 months. Upon the death of any of our NEOs, all unvested options and other long-term incentive awards will automatically vest and become immediately exercisable on the effective date of such death (assuming PSU performance at target).

Restrictive Covenants

Under their respective employment agreements, each of our NEOs is subject to certain restrictive covenants with respect to solicitations and non-competition obligations for a period of 12 months following such executive’s termination, and is subject to certain intellectual property assignment and confidentiality obligations.

All Other Compensation may include a variety of types of compensation, such as car allowance, parking, use of company car, deferred profit sharing, air and ground transportation (including use of the company aircraft), gross up payments, insurance premiums and reimbursement of certain expenses. For Fiscal 2025, for Mr. Soffera, this amount in aggregate was less than $50,000 or 10% of such executive’s salary. For Mr. Dovigi, this amount included $44,155,577 in transaction bonuses, $20,842,429 of premiums for life insurance policies and $30,958,674 in related gross up payments. $13,922,088 of the All Other Compensation paid to Mr. Dovigi was satisfied through the issuance of RSUs that are not otherwise reflected in the Share-Based Awards column above. For Mr. Pelosi, this amount included $8,730,801 of transaction bonuses, $111,783 for use of company car and $146,981 in related gross-up payments. For Ms. Gilbert, this amount included $5,000,000 of transaction bonuses, $44,189 for use of company car and $50,903 in related gross-up payments. For Ms. Grahek, this amount included $4,800,000 of transaction bonuses, $23,664 for use of company car and $27,259 in related gross-up payments. Values for insurance policies are equal to the premiums paid. Values for use of aircraft are equal to the incremental cost to the Company of conferring the benefit, which consists of the average weighted fuel expenses, catering expenses, trip-related crew expenses, landing fees and trip-related hangar/parking costs. Since our aircraft is used primarily for business travel, the valuation excludes the fixed costs that do not change based on usage, such as pilots’ compensation, the lease expense of the aircraft and the cost of maintenance. Values for use of a company car are equal to the standby charge calculated in accordance with applicable tax regulations.

Options granted on March 5, 2020 (“IPO Options”) are subject to multi-year vesting conditions and laddered exercise prices. Options granted on June 29, 2021 (“2021 Options”) are subject to share performance-based vesting conditions, such that one half of such options vested on the date on which the trading price of our subordinate voting shares on the NYSE achieved a volume weighted average price (VWAP) of US$50.00 for 20 consecutive trading days, and one half of such options will vest following the date on which the trading price of our subordinate voting shares on the NYSE achieves a VWAP of US$60.00 for 20 consecutive trading days.

Options are “in-the-money” if the market price of the subordinate voting shares covered by the options is greater than the option exercise price. This value is calculated based on the difference between the closing price of the subordinate voting shares on the NYSE on December 31, 2025 of US$42.95 ($58.87), and the exercise price of the option.

For the purposes of attributing a market value to the shares underlying the Share-Based Awards, being RSUs and PSUs, the value is calculated based on the closing price of the subordinate voting shares on the NYSE on December 31, 2025 of US$42.95 ($58.87) and assuming PSU performance at target. This amount may not represent the actual value of the Share-Based Awards upon distribution.

PERFORMANCE GRAPH

The following graph compares the Company’s cumulative total shareholder return to the S&P/TSX Composite Index, assuming reinvestment of any dividends and considering a $100 investment on March 3, 2020, being the date the Company’s subordinate voting shares began trading on the TSX.

The S&P/TSX Composite Index tracks the share prices of the largest companies on the TSX measured by market capitalization. Stocks included in this index cover all sectors of the economy, are not significantly weighted in any industry comparable to the Company’s and are therefore not directly comparable to the Company. During the period commencing on the first day the Company’s subordinate voting shares began trading on the TSX to the last trading day of Fiscal 2025, the cumulative shareholder return on an investment in the subordinate voting shares increased by 165.6% compared to the S&P/TSX increase of 130.8%.

Description of LTIP

The following discussion provides a high-level description of the material terms and conditions of our LTIP and is qualified in its entirety by the text of the LTIP and each grant

agreement evidencing the applicable awards. The Board has determined to seek shareholder approval for the renewal of the LTIP at the Meeting in accordance with the rules of the TSX, as set out in the resolution in this Circular, which will also approve all unallocated options, rights or other entitlements under the LTIP and allow the Company to continue granting options, rights or other entitlements under the LTIP until May 13, 2029. See “Proposal 3 – LTIP Renewal Resolution”.

Under the terms of the LTIP, our Board, or if authorized by our Board, our NGC Committee, may grant awards to eligible participants, as applicable. The NGC Committee is responsible for administering the Company’s LTIP. Previous grants of equity-based awards may be taken into consideration when making decisions related to equity-based compensation. Participation in the LTIP is voluntary and, if an eligible participant agrees to participate, the grant of awards is evidenced by a grant agreement with each such participant. The interest of any participant in any award is not assignable or transferable, whether voluntarily, involuntarily, by operation of law or otherwise, other than by will or the laws of descent and distribution.

The LTIP provides that, in order to preclude a dilution or enlargement of the benefits under the LTIP, appropriate adjustments, if any, will be made by our Board in the shares issuable or amount payable in connection with a reclassification, reorganization or other change of our shares, share split or consolidation, distribution, merger or amalgamation.

For the purposes of calculating the maximum number of subordinate voting shares reserved for issuance under the LTIP, the DSU Plan and any other security-based compensation arrangement, any issuance from treasury by the Company that is issued in reliance upon an exemption under applicable stock exchange rules applicable to equity based compensation arrangements used as an inducement to person(s) or company(ies) not previously employed by and not previously an insider of the Company shall not be included. All of the shares covered by the exercised, cancelled or terminated awards automatically become available subordinate voting shares for the purposes of awards that may be subsequently granted under the LTIP. As a result, the LTIP is considered an “evergreen” plan. As an evergreen plan, the LTIP is subject to shareholder approval every three years pursuant to the rules of the TSX.

The maximum number of subordinate voting shares that may be: (i) issued to insiders of the Company within any one-year period; and (ii) issuable to insiders of the Company at any time, in each case, under the LTIP alone, or when combined with all of the Company’s other security based compensation arrangements, cannot exceed 10% of the aggregate number of shares issued and outstanding from time to time. The LTIP does not include a maximum that may be issued to an eligible participant. No financial assistance is provided by the Company to eligible participants in connection with the LTIP.

The terms and conditions of grants of options, RSUs and PSUs, including the quantity, type of award, grant date, vesting conditions, vesting periods, settlement date and other terms and conditions with respect to these awards, are set out in the participant’s grant agreement. The impact of certain events upon the rights of holders of these types of awards, including termination for cause, resignation, retirement, termination other than for cause and death or long-term disability, are set out in the participant’s grant agreement.

The participant’s grant agreement provides that options will be exercisable during a period established by our Board which will commence on the date of the grant and will terminate no later than ten years after the date of the granting of the options or such shorter period as the Board may determine. The exercise price of options is determined by the Board when such options are granted, but may not be less than the closing price of the subordinate voting shares on the day prior to the grant of such options. Except as otherwise provided in a participant’s grant agreement, RSUs and PSUs will settle, subject to the achievement of the applicable vesting or other conditions applicable thereto, if any, no later than three years after the date of grant of the award if settled in cash or shares purchased in the open market

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 51

TABLE OF CONTENTS

by the Company, or no later than ten years after the date of the grant of award if settled in shares issued from treasury by the Company, or in each case, such shorter period as our Board may determine. RSUs and PSUs entitle the eligible participant to acquire subordinate voting shares at a purchase price determined by the Board, subject to certain restrictions and conditions as the Board may determine at the time of grant. RSUs and PSUs may be settled in cash, subordinate voting shares or both, in accordance with the terms of the LTIP and the grant agreement.

The LTIP provides that the exercise period for an option shall automatically be extended if the date on which it is scheduled to terminate falls during a black-out period. In such cases, the extended exercise period will terminate ten business days after the last day of the black-out period. In order to facilitate the payment of the exercise price of the options, the LTIP has a cashless exercise feature pursuant to which participants may elect to undertake either a broker assisted “cashless exercise” or a “net exercise” subject to the procedures set out in the participant’s grant agreement, including the consent of our Board, where required.

In the event of a change of control of the Company, our Board has the discretion to, among other things, accelerate the vesting of outstanding awards, settle outstanding awards in cash or exchange outstanding awards for similar awards of a successor company.

Our Board may, in its sole discretion, suspend or terminate the LTIP at any time, or from time to time, amend, revise or discontinue the terms and conditions of the LTIP or of any securities granted under the LTIP and any grant agreement relating thereto, subject to any required regulatory and exchange approval, provided that such suspension, termination, amendment, or revision does not adversely alter or impair any award previously granted except as permitted by the terms of the LTIP or as required by applicable laws.

Our Board may amend the LTIP or any securities granted under the LTIP at any time without the consent of a participant provided that such amendment: (i) does not adversely alter or impair any award previously granted except as permitted by the terms of the LTIP or with consent of the participant; (ii) is in compliance with applicable law and subject to any regulatory approvals including, where required, the approval of the TSX or NYSE; and (iii) is subject to shareholder approval, where required by law, the requirements of the TSX, NYSE or the LTIP, provided however that shareholder approval will not be required for the following amendments and our Board may make any changes which may include but are not limited to:

•

any amendment to the vesting provisions, if applicable, or assignability provisions of awards;

•

any amendment regarding the effect of termination of a participant’s employment or engagement;

•

any amendment which accelerates the date on which any award may be exercised under the LTIP;

•

any amendment necessary to comply with applicable law or the requirements of the TSX, NYSE, any other exchange upon which the securities of the Company are then listed, or any other regulatory body;

•

any amendment of a “housekeeping” nature, including, without limitation, to clarify the meaning of an existing provision of the LTIP, correct or supplement any provision of the LTIP that is inconsistent with any other provision of the LTIP, correct any grammatical or typographical errors or amend the definitions in the LTIP;

•

any amendment regarding the administration of the LTIP; and

•

any other amendment that does not require the approval of shareholders pursuant to the amendment provisions of the LTIP,

provided that the alteration, amendment or variance does not:

increase the maximum number of subordinate voting shares issuable under the LTIP, other than an adjustment pursuant to a change in capitalization;

•

reduce the exercise price of awards;

•

extend the expiration date of an award benefitting an insider of the Company, except in the case of an extension due to a black-out period;

•

INDEBTEDNESS OF DIRECTORS AND EXECUTIVE OFFICERS

None of our directors, executive officers, employees, former directors, former executive officers or former employees or any of our subsidiaries, and none of their respective associates, is or has within 30 days before the date of this Circular or at any time since the beginning of the most recently completed financial year been indebted to us or any of our subsidiaries or another entity whose indebtedness is the subject of a guarantee, support agreement, letter of credit or other similar agreement or understanding provided by us or any of our subsidiaries.

CORPORATE GOVERNANCE

General

The Company and Board believe that sound corporate governance practices are essential to the proper and effective management and operation of our business. This includes compliance with applicable regulatory requirements and best practices that go beyond the requirements mandated by regulation. The Company continues to monitor corporate governance developments with a view to further enhancing its governance policies and practices, as appropriate.

We recognize that good corporate governance plays an important role in our overall success and in enhancing shareholder value and, accordingly, we have adopted certain corporate governance policies and practices.

As a corporation incorporated under the OBCA and listed on both the TSX and the NYSE, the Company is subject to various Canadian and U.S. legislation, rules, regulations, standards and recommendations related to governance practices. The Board and senior management believe that the Company’s current governance practices are appropriate and comply in all material respects with the requisite regulatory and statutory requirements, including National Instrument 58-101 – Disclosure of Corporate Governance Practices (“NI 58-101”), the corporate governance rules of the NYSE and TSX, and applicable Canadian and U.S. corporate and securities laws.

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 53

Board of Directors

Director Independence

Under the NYSE Listing Rules, an independent director means a person who, among other things, in the opinion of our Board, has no material relationship with our Company. Under NI 58-101, a director is considered to be independent if he or she is independent within the meaning of Section 1.4 of National Instrument 52-110 – Audit Committees (“NI 52-110”). Pursuant to NI 52-110, an independent director is a director who is free from any direct or indirect material relationship with us which could, in the view of our Board, be reasonably expected to interfere with the exercise of a director’s independent judgement.

Of the eight directors nominated for election at the Meeting, seven (or 88%) are independent. As such, the Board will be composed of a majority of independent directors. Based on information provided by each director concerning his or her background, employment and affiliations, our Board has determined that Mr. Dovigi is not considered “independent” as that term is defined under the NYSE Listing Rules and NI 58-101 as a result of Mr. Dovigi being our Chief Executive Officer. Certain members of our Board are also members of the board of other public companies. See “Proposal 1 – Election of Directors – Description of Proposed Director Nominees”.

Meetings of Independent Directors

Our Board believes that given its size and structure, it is able to facilitate independent judgement in carrying out its responsibilities. To enhance such independent judgement, the independent directors of the Company meet in camera without the non-independent directors and members of management present at the end of every meeting of the Board. In addition, any independent director may, at any time, if considered necessary to facilitate open and candid discussion among the independent directors, call a meeting or request an in camera session without management and non-independent directors.

Our Board has not appointed an independent chair. However, Dino Chiesa has been appointed as Lead Independent Director by our Board and is responsible for ensuring that the directors who are independent of management have opportunities to meet without management present. Discussions are led by the Lead Independent Director who subsequently provides feedback to the Chair. The Lead Independent Director may be appointed and replaced from time to time by a majority of independent directors and will be an independent director.

In addition to the regular in camera meetings described above, a special committee of independent and disinterested directors met on two occasions in Fiscal 2025 to consider and ultimately recommend to the Board the approval of the purchase for cancellation by the

54 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

Company of certain subordinate voting shares offered for sale pursuant to secondary offering transactions initiated by the Company’s shareholders in March 2025 and November 2025.

Conflicts of Interest and Related Party Transactions

Under our written code of ethics (the “Code of Ethics”), directors, officers, employees and other representatives of the Company are expected to put the interests of GFL before their own. Representatives must avoid situations involving a conflict, or potential conflict, between their personal, family or business interests, and the interests of GFL, and must promptly disclose any such conflict, or potential conflict. A director has a statutory responsibility to disclose all actual or potential conflicts of interest related to matters before our Board or any committee on which he or she serves as soon as the director becomes aware of it. In situations where a director has a conflict of interest in the matter to be considered by our Board or the committee, such director must comply with the relevant provisions of the OBCA, which may include absenting themself from the meeting while discussions are taking place and abstaining from voting with respect to the matter. A director is generally considered to have a “conflict of interest” in any situation in which a director has a personal or financial interest in a matter which is the subject of an action or decision by the Company that may reasonably be perceived to: (i) affect the objectivity of the director in carrying out their responsibilities and duties or (ii) represent an advantage or gain to the director or other persons with whom the director does not deal at arm’s length.

The Audit Committee is responsible for reviewing all material related party transactions other than those delegated to a special committee or independent committee of the Board. In satisfying its mandate, the Audit Committee considers applicable legal and regulatory requirements, discusses with management the business rationale for the transactions, reviews applicable disclosures and reports to the Board on all such transactions, if any, each quarter. The Audit Committee is considered the appropriate committee to assess related party transactions given the additional independence requirements required of each committee member pursuant to applicable securities laws. The Audit Committee is responsible for ensuring all such transactions are on arm’s length and commercially reasonable terms and are supported by third party appraisals or valuations where applicable. For purposes of this policy, “related party” includes directors and officers of the Company and applies to any agreement entered into with such related party.

Director Commitments

The Board, with the assistance of the NGC Committee, monitors the demands placed on each director’s time and attention outside of their service on the Board. This includes, among other things, reviewing the number of other public company boards that a director sits on to ensure that no director has excessive commitments to other public companies that may result in a reduced ability for the director to provide effective oversight as a Board member. In this regard, each director is required to notify and discuss with the Chair of the NGC Committee prior to accepting a directorship at another public company.

The Board, with the assistance of the NGC Committee, also monitors interlocking board and committee memberships among all directors. Board interlocks exist when two directors of one public company sit on the board of another public company and committee interlocks exist when two directors sit together on another public company board and are also members of the same board committee.

Director Term Limits and Other Mechanisms of Board Renewal

Our Corporate Governance Guidelines provide that a director who has served for a term that exceeds 15 years from the later of March 5, 2020 and the date on which the director first began serving on the Board (the “Term Limit”) shall not stand for re-election at the next

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 55

TABLE OF CONTENTS

annual shareholder meeting held subsequent to the expiration of the Term Limit. The Term Limit does not apply to directors who are executive officers of the Company or are nominated pursuant to the Investor Rights Agreements.

Our NGC Committee also conducts a process for the assessment of our Board, each committee and each director regarding their or its effectiveness and performance, and reports evaluation results to our Board. For further information on the composition of our Board and the annual assessment process, see also “Board and Senior Executive Inclusion Policy” and “Mandate of our Board of Directors”.

Mandate of our Board of Directors

Our Board is responsible for supervising the management of the business and affairs of the Company. Our Board has adopted the written mandate set forth in Appendix “A” that includes the following responsibilities, among others:

•

adopting a strategic planning process, approving the principal business objectives for the Company and approving major business decisions and strategic initiatives;

•

approving, on at least an annual basis, a strategic plan which takes into account, among other things, the opportunities and risks of the Company’s business and affairs;

•

monitoring the implementation of procedures, policies and initiatives relating to corporate governance, risk management, corporate social responsibility, health and safety, ethics and integrity;

•

identifying the principal risks of the Company’s business and overseeing management’s implementation of appropriate systems to monitor, manage and mitigate such risks;

•

appointing the Chief Executive Officer of the Company and developing the corporate goals and objectives that the Chief Executive Officer should meet, and reviewing the performance of the Chief Executive Officer against such goals and objectives;

•

taking steps to satisfy itself as to the integrity of the Chief Executive Officer and other senior executive officers and that the Chief Executive Officer and other senior executive officers create a culture of integrity throughout the organization; and

•

approving the succession plan for the Company’s senior executive officers.

Oversight and guidance on the Company’s strategy, including with respect to business, sustainability and human capital matters, is one of the Board’s primary roles. On an annual basis, management of the Company, including the Chief Executive Officer, collaborates with the Board to develop, review and update the Company’s strategic plan. On at least a quarterly basis, the Board reviews the Company’s performance with respect to employee health and safety and turnover metrics.

Our Board, in conjunction with the NGC Committee, also evaluates and assesses, on an annual basis, the performance and effectiveness of our Board and the committees thereof and the contributions of the individual Board members. The assessment addresses, among other things, individual director performance, individual director and overall Board skills and attributes and individual director independence and financial literacy. Our Board receives and considers the recommendations from the NGC Committee regarding the results of the evaluation of the performance and effectiveness of our Board and committees.

and disclosure, protection and proper use of our assets, communications, fair dealing, fair competition, due diligence, illegal payments, equal employment opportunities and harassment, privacy, use of Company computers and the internet, political and charitable activities and reporting any violations of law, regulation or the Code of Ethics. Any person subject to the Code of Ethics should report all violations of law, regulation or of the Code of Ethics of which they become aware to any one of our senior executives. Our Board has ultimate responsibility for monitoring compliance with the Code of Ethics. The Code of Ethics is available on our investor relations website at http://investors.gflenv.com under “Governance Documents” and has been filed with the Canadian securities regulatory authorities on SEDAR+ at http://www.sedarplus.ca.

Waivers of the Code of Ethics will be granted only in advance and under exceptional circumstances by the NGC Committee.

Independent, Anonymous Complaint Process

We have adopted a written whistleblower policy (the “Whistleblower Policy”), which sets out and describes procedures governing the receipt, retention and treatment of complaints regarding, among other things, accounting, internal accounting controls or auditing matters, violations of applicable law, rules or regulations that relate to corporate reporting and disclosure, or violations of the Code of Ethics, and any other concerns regarding behavior or conduct that may be considered unethical, suspicious, fraudulent or illegal.

The Company maintains a third-party managed confidential reporting platform that permits the reporting of complaints in accordance with the Whistleblower Policy, including on an anonymous basis at the election of the complainant. The distribution of all confidential complaint reports is strictly limited to appropriate members of senior management who need to know of the complaint to ensure that the complaint is properly investigated and addressed.

Disclosure Policy

We have adopted a written disclosure policy (the “Disclosure Policy”), which outlines the procedures and practical guidelines for timely disclosure of information about the Company to the investing public, in accordance with applicable legal and regulatory requirements, and is intended to protect and prevent the improper use or disclosure of undisclosed material information or otherwise confidential information about the Company. The Disclosure Policy applies to all directors, officers, employees, consultants and contractors of the Company who have access to confidential corporate information, including undisclosed material information, and those persons authorized to speak on the Company’s behalf and to all disclosure in any medium, including to shareholders, the investment community and the media.

Anti-Corruption Policy

We have adopted an anti-corruption policy (the “Anti-Corruption Policy”), which confirms our commitment to comply fully with the Canadian Criminal Code, Corruption of Foreign Public Officials Act, the Freezing Assets of Corrupt Foreign Officials Act, the United States

Communications with the Board and Management

Shareholders and other interested parties may communicate with the Board generally, with the independent directors as a group or with a specific director at any time by writing to the Board, the independent directors or a specific director, to the attention of the Corporate Secretary, at our executive headquarters located at 1759 Purdy Avenue, Suite 300, Miami Beach, Florida 33139.

Shareholders and other interested parties are also able to communicate with the Board and management through the Company’s investor relations email at ir@gflenv.com.

Shareholder Outreach and Engagement

We believe that our relationship with and accountability to our shareholders are important to our success. Engaging with our shareholders helps us to understand their perspective and to set goals and expectations for our performance. This engagement also helps us to identify emerging issues that may affect our strategies, corporate governance, compensation practices or other aspects of our operations. Our shareholder and investor outreach includes shareholder meetings, investor road shows, analyst meetings and investor conferences. Our Board encourages shareholder attendance and participation at our annual general meetings in particular, as this provides a valuable opportunity to engage with the Company with regard to corporate governance and other important matters.

We also communicate with shareholders and other interested parties through various media, including our annual and quarterly reports, press releases and our website. Our conference calls for quarterly earnings releases and major corporate developments are open to all. Our Chief Executive Officer, Chief Financial Officer and other senior management also regularly meet with investors to discuss our strategy, financial and business performance and to update investors on key developments.

In addition, shareholders can contact the Board at any time during the year by mail at 1759 Purdy Avenue, Suite 300, Miami Beach, Florida 33139, Attention: Corporate Secretary, or by e-mail to ir@gflenv.com. The Board will endeavor to respond to all appropriate correspondence in a timely manner.

Committees of our Board

Our Board has established two committees: the Audit Committee and the NGC Committee.

60 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

Audit Committee

Our Audit Committee consists of three directors, all or 100% of whom are persons determined by our Board to meet the independence requirements for audit committees under the rules of the NYSE and NI 52-110. Our Audit Committee is composed of Arun Nayar, who acts as Chair of the committee, Dino Chiesa, and Violet Konkle. Each of our Audit Committee members has an understanding of the accounting principles used to prepare financial statements and varied experience as to the general application of such accounting principles, as well as an understanding of the internal controls and procedures necessary for financial reporting. The Board has also determined that each of the Audit Committee members is “financially literate” within the meaning of the rules and regulations of the NYSE and NI 52-110 and that they each qualify as an “audit committee financial expert” as defined under applicable SEC rules and regulations.

Our Board has adopted the written charter set forth in Appendix “B” that includes the purpose, composition, authority and responsibility of our Audit Committee, consistent with NI 52-110. The Audit Committee assists our Board in fulfilling its oversight of:

•

our financial statements and financial reporting processes;

•

our systems of internal accounting and financial controls;

•

enterprise risk management;

•

financial risk management, including financial risks associated with climate change, sustainability and environmental and social matters;

•

the annual independent audit of our financial statements;

•

the independent auditor’s qualifications and independence;

•

the performance of the independent auditor;

•

the design and implementation of our internal audit function, and the performance of our internal audit function;

•

legal and regulatory compliance;

•

reviewing and monitoring compliance with debt covenants and reviewing the process and reports with which we measure financial results or performance;

•

reviewing and approving material transactions with related parties of the Company, to ensure the transactions are on arm’s length and commercially reasonable terms, supported by third party appraisals or valuations, where applicable; and

•

public disclosure items such as quarterly press releases, financial-oriented investor relations materials and other public reporting requirements.

As part of its oversight of enterprise risk management, the Audit Committee is also responsible for reviewing and making recommendations to the Board regarding the adequacy of the Company’s risk assessment and management policies and procedures with regard to identification of the Company’s principal risks and implementation of appropriate systems and controls to manage such risks, including risk management for information technology, cybersecurity and artificial intelligence implementation and governance and related IT infrastructure security and management. To assist the Audit Committee with its oversight of enterprise risk management, we provide informational sessions throughout the year on topics determined by the Board to represent the greatest risks to the Company, including health and safety, information technology and cyber security.

It is the responsibility of the Audit Committee to maintain free and open means of communication between the Audit Committee, the external auditor and the management of

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 61

TABLE OF CONTENTS

the Company. The Audit Committee is given full access to our management and records and external auditor as necessary to carry out these responsibilities. The Audit Committee has the authority to carry out such special investigations as it sees fit in respect of any matters within its various roles and responsibilities. We provide appropriate funding, as determined by the Audit Committee, for the payment of compensation to the independent auditor for the purpose of rendering or issuing audit reports and to any advisors retained by the Audit Committee.

We have also formed a Risk Management Steering Committee. The Risk Management Steering Committee oversees the implementation of our enterprise risk management system, including all of our operational, financial, strategic, reputational, employee, health and safety, legal and regulatory, information technology and sustainability-related risks and opportunities. The Risk Management Steering Committee is composed of our senior executives including our Chief Executive Officer, Chief Financial Officer, Chief Operating Officer, Chief Legal Officer and Executive Vice President, Strategic Initiatives, as well as other corporate Vice Presidents. The Risk Management Steering Committee works directly with business leaders across the Company to identify and mitigate significant risks to the organization. The Risk Management Steering Committee reports to the Audit Committee on the implementation and management of our enterprise risk management system.

For additional details regarding the relevant education, skills and experience of each member of our Audit Committee, see “Proposal 1 – Election of Directors – Description of Proposed Director Nominees” and the director skills matrix under “Mandate of our Board of Directors”.

Nomination, Governance and Compensation Committee

Our Board has established the NGC Committee, which is composed of five directors, all or 100% of whom are persons determined by our Board to be independent directors, and is charged with reviewing, overseeing and evaluating our compensation, corporate governance and nominating policies. Our NGC Committee is composed of Paolo Notarnicola, who acts as Chair of the committee, Dino Chiesa, Sandra Levy, Jessica McDonald and Arun Nayar. No member of our NGC Committee is an officer of the Company, and as such, our Board believes that our NGC Committee is able to conduct its activities in an objective manner.

Our Board has adopted a written charter setting forth the purpose, composition, authority and responsibility of our NGC Committee consistent with our Corporate Governance Guidelines. Our NGC Committee’s purpose is to assist our Board in:

•

the appointment, evaluation and compensation of our named executive officers;

•

the recruitment, development and retention of our named executive officers;

•

maintaining talent management and succession planning systems and processes relating to our named executive officers;

•

developing the compensation structure for our named executive officers including salaries, annual and long-term incentive plans including plans involving share issuances and other share-based awards;

•

establishing policies and procedures designed to identify and mitigate risks associated with our compensation policies and practices;

•

assessing the compensation of our directors;

•

developing benefit retirement and savings plans;

•

developing our corporate governance guidelines and principles and providing us with governance leadership;

62 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

•

overseeing our policies and practices with regards to environmental, social and governance matters;

•

guiding management in the identification of sustainability and corporate responsibility strategies, goals and objectives and reviewing our performance towards such strategies, goals and objectives;

•

identifying individuals qualified to be nominated as members of our Board;

•

reviewing the structure, composition and mandate of our Board committees; and

•

evaluating the performance and effectiveness of our Board and of our Board committees.

Our NGC Committee is responsible for evaluating and assessing, on an annual basis, the performance and effectiveness of our Board and the committees thereof and the contributions of the individual Board members. The assessment addresses, among other things, individual director independence, individual director and overall Board skills and attributes and individual director financial literacy. Our Board receives and considers the recommendations from our NGC Committee regarding the results of its evaluation. Our NGC Committee is also responsible for orientation and continuing education programs for our directors.

In support of its succession planning responsibilities, the NGC Committee retained an independent executive search consultant to assist it with formalizing the succession plan for the Chief Executive Officer and other NEOs. The succession plan includes policies and principles for selecting and evaluating a new Chief Executive Officer in the event of an emergency or retirement of the Chief Executive Officer. As part of its development of the succession plan, the independent executive search consultant conducted in-depth meetings with each of the Chief Executive Officer and other NEOs, as well as certain of their direct reports. The final succession plan was approved in 2023.

In support of its director nomination responsibilities, and in addition to regularly-scheduled committee meetings, the NGC Committee meets informally throughout the year with search consultants and potential director nominee candidates.

Our NGC Committee monitors the composition of our Board and senior management, recognizing the importance and benefit of having highly talented and experienced individuals who reflect the diversity of our stakeholders, including our customers and employees as well as the changing demographics of the communities in which we operate. In support of this goal and in accordance with our inclusion policy, the NGC Committee considers, among other factors, criteria that promote diversity, including with regard to age, skill, socioeconomic background, gender, ethnicity and other dimensions. In 2022, our Board established as its objective that women should comprise at least 30% of the Board. The Company achieved this objective in early 2023, and, as a result, the Company no longer maintains a target number or percentage regarding women on the Board.

Of the eight directors nominated for election at the Meeting, women represent 38%, or 43% of the independent directors. In addition, two members of our Board identify as members of visible minorities and one individual identifies as LGBTQIA+.

For additional details regarding the relevant education, skills and experience of each member of our NGC Committee, see “Proposal 1 – Election of Directors – Description of Proposed Director Nominees” and the director skills matrix under “Mandate of our Board of Directors”.

Sustainability Matters

The Company believes that environmental, organization and financial sustainability initiatives are key components of our continued success. The Board is responsible for the oversight of

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 63

TABLE OF CONTENTS

sustainability matters, including in relation to (i) strategies, policies, systems and processes of the Company, (ii) management of risks relating to sustainability matters and (iii) compliance with statutory and regulatory obligations.

We have formed a Sustainability Initiatives Committee (the “SUSIC”) composed of our Chief Executive Officer, Chief Financial Officer, Chief Operating Officer, Chief Legal Officer, Chief Human Resources Officer, Executive Vice President, Strategic Initiatives and other corporate Vice Presidents, including the Senior Vice President, Renewables, Environmental Responsibility & Sustainability. The SUSIC is responsible for identifying our sustainability goals and strategies to ensure that sustainability continues to be integrated across our operations and defining our sustainability related key performance indicators to ensure accountability for achieving our goals and commitments. The SUSIC considers and recommends for the approval of the NGC Committee those sustainability goals, objectives and commitments that will be disclosed to the public and the format and timing of such disclosures. The SUSIC meets on a quarterly basis and reports semi-annually to the NGC Committee on the progress made toward implementing our identified sustainability goals, objectives and commitments.

We have established a Sustainability Action Plan to formalize our sustainability efforts and goals, which include increasing our recyclables recovered at our material recovery facilities by 40%, reducing our total scope 1 and 2 greenhouse gas emissions by 30%, doubling the beneficial use of biogas generated from our landfills and having renewable natural gas power at least 85% of our compressed natural gas solid waste collection fleet in the United States, all by 2030.

Our Safe for Life program recognizes that our employees are our greatest asset and strongest resource in assessing, correcting and executing safe practices. Safe For Life provides our employees with best-in-class knowledge, training and tools to perform their jobs safely and effectively in compliance with all applicable regulatory requirements. In addition, as part of the Safe for Life Program, we have adopted technology (including electronic in-cab devices and software compliance tools) and innovations designed to help us achieve our health and safety goals.

We have been recognized by several health and safety organizations, as well as receiving Certificates of Recognition from several provinces in Canada issued to companies that provide evidence of their ongoing commitment to safety in the workplace.

The Company’s sustainability reports, including descriptions of key sustainability-related programs, are available on the “Sustainability” section of our website at http:// investors.gflenv.com. The Company’s sustainability-related policies are available on the “Governance Documents” section of our website at http://investors.gflenv.com.

Achievement of our sustainability and safety targets, goals and objectives is taken into account in calculating non-equity incentive compensation granted to NEOs. See “Compensation Discussion and Analysis – Principal Elements of Compensation”.

Board and Senior Executive Inclusion Policy

We recognize the importance and benefit of having a Board and senior management composed of highly talented and experienced individuals who reflect the diversity of our stakeholders, including our customers and employees as well as the changing demographics of the communities in which we operate. We have therefore adopted a written inclusion policy (the “Inclusion Policy”) which provides that the Board and the NGC Committee will, when identifying candidates to nominate for election to our Board or appoint as senior management, in compliance with applicable laws, regulations or other legal requirements:

•

consider individuals who are highly qualified, based on their talents, experience, functional expertise and personal skills, character and qualities having regard to our current and future plans and objectives, as well as anticipated regulatory and market developments;

64 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

•

consider criteria that promote diversity, including with regard to age, skill, socioeconomic background, gender, ethnicity and other characteristics; and

•

as required, engage qualified independent external advisors to assist our Board in conducting its search for candidates that meet the Board’s criteria, including regarding skills and experience.

Of the eight directors nominated for election at the Meeting, women represent 38%, or 43% of the independent directors. Two members of our Board identify as members of visible minorities and one individual identifies as LGBTQIA+. In addition, women represent 40% of our named executive officers.

We continue to prioritize investing in our workforce, including through formal mentorship programs and Employee Sustainability Committees.

Holders of subordinate voting shares are entitled to one vote per subordinate voting share on all matters upon which shareholders are entitled to vote. As of March 31, 2026, the subordinate voting shares represented approximately 93.3% of our total issued and outstanding shares and approximately 72.3% of the voting power attached to all of our shares. The subordinate voting shares are “restricted securities” within the meaning of National instrument 51-102 – Continuous Disclosure Obligations.

Holders of multiple voting shares are entitled to 10 votes per multiple voting share on all matters upon which shareholders are entitled to vote. As of March 31, 2026, the multiple voting shares represented approximately 3.2% of our total issued and outstanding shares and approximately 24.6% of the voting power attached to all of our shares.

Each holder of Convertible Preferred Shares is entitled to vote, to the greatest extent possible, with holders of subordinate voting shares and multiple voting shares as a single class. Holders of Convertible Preferred Shares are entitled to one vote per Convertible Preferred Share held as of the applicable record date, provided that each holder is deemed to have held such number of Convertible Preferred Shares that is equal to the number of subordinate voting shares into which such holder’s Convertible Preferred Shares were convertible pursuant to the terms of the Convertible Preferred Shares as of such date. As of March 31, 2026, 14,782,495 subordinate voting shares issuable upon conversion of the Convertible Preferred Shares were entitled to be voted at the Meeting.

This summary is qualified by reference to, and is subject to, the detailed provisions of our Articles.

Certain Amendments

In addition to any other voting right or power to which the holders of subordinate voting shares shall be entitled by law or regulation or other provisions of our Articles from time to

GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR 65

TABLE OF CONTENTS

time in effect, but subject to the provisions of our Articles, holders of subordinate voting shares shall be entitled to vote separately as a class, in addition to any other vote of shareholders that may be required, in respect of any alteration, repeal or amendment of our Articles which would adversely affect the rights or special rights of the holders of subordinate voting shares or affect the holders of subordinate voting shares and multiple voting shares differently, on a per share basis, including an amendment to the terms of our Articles that provide that any multiple voting shares sold or transferred to a Person that is not a Permitted Holder shall be automatically converted into subordinate voting shares.

Pursuant to our Articles, holders of subordinate voting shares and multiple voting shares are treated equally and identically, except with respect to voting and conversion, on a per share basis, in certain change of control transactions that require approval of our shareholders under the OBCA, unless different treatment of the shares of each such class is approved by a majority of the votes cast by the holders of our subordinate voting shares and multiple voting shares, each voting separately as a class.

For the purposes of the foregoing:

“Permitted Holders” means Patrick Dovigi and the spouse or legal equivalent, the parents and/or the lineal descendants of Patrick Dovigi (the “Dovigi Related Persons”) or any trust, partnership, corporation, limited liability company or other estate or planning or investment vehicle in which no other Person has any legal, economic, beneficial or other interest other than such holder and/or the Dovigi Related Persons, as applicable, and with respect to which, a transfer does not result in any change in the effective control of such holder’s securities.

“Person” means any individual, partnership, corporation, company, association, trust, joint venture or limited liability company.

Take-Over Bid Protection

Under applicable securities laws in Canada, an offer to purchase multiple voting shares would not necessarily require that an offer be made to purchase subordinate voting shares. In accordance with the rules of the TSX designed to ensure that, in the event of a take-over bid, the holders of subordinate voting shares will be entitled to participate on an equal footing with holders of multiple voting shares, the Dovigi Group entered into a coattail agreement with a trustee on March 5, 2020 (the “Coattail Agreement”). The Coattail Agreement contains provisions customary for dual class, TSX-listed corporations designed to prevent transactions that otherwise would deprive the holders of subordinate voting shares of rights under applicable securities laws in Canada to which they would have been entitled if the multiple voting shares had been subordinate voting shares. See “Coattail Agreement” below.

The undertakings in the Coattail Agreement do not apply to prevent a sale by the holders of multiple voting shares or Permitted Holders of multiple voting shares if concurrently an offer is made to purchase subordinate voting shares that:

(a)

offers a price per subordinate voting share at least as high as the highest price per share to be paid pursuant to the take-over bid for the multiple voting shares;

(b)

provides that the percentage of outstanding subordinate voting shares to be taken up (exclusive of subordinate voting shares owned immediately prior to the offer by the offeror or persons acting jointly or in concert with the offeror) is at least as high as the percentage of multiple voting shares to be sold (exclusive of multiple voting shares owned immediately prior to the offer by the offeror and persons acting jointly or in concert with the offeror);

(c)

has no condition attached other than the right not to take up and pay for subordinate

66 GFL ENVIRONMENTAL INC. | 2026 INFORMATION CIRCULAR

TABLE OF CONTENTS

voting shares tendered if no multiple voting shares are purchased pursuant to the offer for multiple voting shares; and

(d)

is in all other material respects identical to the offer for multiple voting shares.

In addition, the Coattail Agreement does not prevent the transfer of multiple voting shares by the Dovigi Group to its Permitted Holders, provided such transfer is not or would not have been subject to the requirements to make a take-over bid (if the vendor or transferee were in Canada) or constitutes or would be exempt from certain requirements applicable to take-over bids under applicable securities laws in Canada. The conversion of multiple voting shares into subordinate voting shares, whether or not such subordinate voting shares are subsequently sold, would not constitute a disposition of multiple voting shares for the purposes of the Coattail Agreement.

Coattail Agreement

Under the Coattail Agreement, any sale of multiple voting shares (including a transfer to a pledgee as security) by a holder of multiple voting shares party to the Coattail Agreement is conditional upon the transferee or pledgee becoming a party to the Coattail Agreement, to the extent such transferred multiple voting shares are not automatically converted into subordinate voting shares in accordance with our Articles.

The Coattail Agreement contains provisions for authorizing action by the trustee to enforce the rights under the Coattail Agreement on behalf of the holders of the subordinate voting shares. The obligation of the trustee to take such action is conditional on us or holders of the subordinate voting shares providing such funds and indemnity as the trustee may reasonably require. No holder of subordinate voting shares has the right, other than through the trustee, to institute any action or proceeding or to exercise any other remedy to enforce any rights arising under the Coattail Agreement unless the trustee fails to act on a request authorized by holders of not less than 10% of the outstanding subordinate voting shares and reasonable funds and indemnity have been provided to the trustee.

Other than in respect of non-material amendments and waivers that do not adversely affect the interests of holders of subordinate voting shares, the Coattail Agreement provides that, among other things, it may not be amended, and no provision thereof may be waived, unless, prior to giving effect to such amendment or waiver, the following have been obtained: (a) the consent of the TSX and any other applicable securities regulatory authority in Canada; and (b) the approval of at least two-thirds of the votes cast by holders of subordinate voting shares represented at a meeting duly called for the purpose of considering such amendment or waiver, excluding votes attached to subordinate voting shares held by the holders of multiple voting shares or their affiliates and related parties and any persons who have an agreement to purchase multiple voting shares on terms which would constitute a sale or disposition for purposes of the Coattail Agreement, other than as permitted thereby. Non-material amendments and waivers that do not adversely affect the interests of holders of subordinate voting shares shall be subject to the approval of the TSX, but shall not require approval of holders of subordinate voting shares.

No provision of the Coattail Agreement limits the rights of any holders of subordinate voting shares under applicable law.

Investor Rights Agreements

Certain aspects of the composition and functioning of our Board may be subject to the rights of the Investors under the Investor Rights Agreements, which, among other things, provide for certain director nomination rights. See “Proposal 1 – Election of Directors – Investor Rights Agreements.”

TABLE OF CONTENTS

The Committee shall discharge its responsibilities, and shall assess the information provided by the Company’s management and the external advisers, in accordance with its business judgment. Members are entitled to rely, absent knowledge to the contrary, on the integrity of the persons and organizations from whom they receive information, and on the accuracy and completeness of the information provided. Nothing in this Charter is intended or may be construed as imposing on any member of the Committee or the Board a standard of care or diligence that is in any way more onerous or extensive than the standard to which the directors are subject under applicable law.

The Committee also has the authority to communicate directly with internal and external auditors. While the Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Committee to plan or conduct audits or to determine that the Company’s financial statements are complete and accurate or comply with IFRS and other applicable requirements. These are the responsibilities of the senior executives of the Company responsible for such matters and the external auditors. The Committee, the Chair and any Members identified as having accounting or related financial expertise are members of the Board, appointed to the Committee to provide broad oversight of the financial, risk and control related activities of the Company, and are specifically not accountable or responsible for the day to day operation or performance of such activities. Although the designation of a Member as having accounting or related financial expertise for disclosure purposes is based on that individual’s education and experience, which that individual will bring to bear in carrying out his or her duties on the Committee, such designation does not impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the Committee and Board in the absence of such designation. Rather, the role of a Member who is identified as having accounting or related financial expertise, like the role of all Members, is to oversee the process, not to certify or guarantee the internal or external audit of the Company’s financial information or public disclosure. This Charter is not intended to change or interpret the constating documents of the Company or applicable laws or stock exchange rules to which the Company is subject, and this Charter should be interpreted in a manner consistent with all such applicable laws and rules.

The Board may, from time to time, permit departures from the terms of this Charter, either prospectively or retrospectively to the extent permitted under applicable law and listing standards. This Charter is not intended to give rise to civil liability on the part of the Company or its directors or officers to shareholders, security holders, customers, suppliers, competitors, employees or other persons, or to any other liability whatsoever on their part.

Section 8 Code of Ethics

The Committee is responsible for reviewing and evaluating the Company’s Code of Ethics at least annually and will recommend any necessary or appropriate changes to the Board for consideration.

Section 9 Review of Charter

The Committee shall review and assess annually the adequacy of this Charter and recommend any proposed changes to the Board for consideration.
