Each outstanding Multiple Voting Share may at any time, at the option of the holder, be converted into one fully paid and non-assessable Subordinate Voting Share, in the following manner: The conversion right which provision is made in this subsection 1.2(4) shall be exercised by notice in writing given to the transfer agent of the Company, if one exists, and if not, to the Company at its registered office, accompanied by a certificate or certificates representing the Multiple Voting Shares in respect of which the holder desires to exercise such conversion right or the equivalent in any non-certificated inventory system (such as, for example, a Direct Registration System) administered by any applicable depository or transfer agent of the Company. Such notice shall be signed by the holder of the Multiple Voting Shares in respect of which such conversion right is being exercised, or by the duly authorized representative thereof, and shall specify the number of Multiple Voting Shares which such holder desires to have converted. On any conversion of Multiple Voting Shares, the Subordinate Voting Shares resulting therefrom shall be registered in the name of the registered holder of the Multiple Voting Shares converted or, subject to payment by the registered holder of any stock transfer or applicable taxes and compliance with any other reasonable requirements of the Company in respect of such transfer, in such name or names as such registered holder may direct in writing. a. Upon receipt of such notice and certificate or certificates and, as applicable, compliance with such other requirements, the Company shall, at its expense, effective as of the date of such receipt and, as applicable, compliance, remove or cause the removal of such holder from the register of holders in respect of the Multiple Voting Shares for which the conversion right is being exercised, add the holder (or any person or persons in whose name or names such converting holder shall have directed the resulting Subordinate Voting Shares to be registered) to the securities register of holders in respect of the resulting Subordinate Voting Shares, cancel or cause the cancellation of the certificate or certificates representing such Multiple Voting Shares and issue or cause to be issued a certificate or certificates, or the equivalent in any non-certificated inventory system (such as, for example, a Direct Registration System) administered by any applicable depository or transfer agent of the Company, representing the Subordinate Voting Shares issued upon the conversion of such Multiple Voting Shares. If less than all of the Multiple Voting Shares represented by any certificate are to be converted, the holder shall be entitled to receive a new certificate representing the Multiple Voting Shares represented by the original certificate which are not to be converted. b. Automatic Conversion Each Multiple Voting Share will convert automatically, without any further action, into one (1) fully paid and non-assessable Subordinate Voting Share if any such Multiple Voting Share is transferred, sold, assigned or exchanged to, or otherwise held by, a Person that is not a Permitted Holder. Upon the first date that any Multiple Voting Share shall be held other than by a Permitted Holder, the Permitted Holder which held such Multiple Voting Share until such date, without any further action, shall automatically be deemed to have exercised his, her or its rights under subsection 1.2(4) to convert such Multiple Voting Share into one (1) fully paid and non-assessable Subordinate Voting Share. a. In addition: all Multiple Voting Shares will convert automatically, without any further action, into an equal number of Subordinate Voting Shares at such time that is the earlier to occur of the i. b. 5.

Certain Class Votes In connection with any Change of Control Transaction requiring approval of the holders of Subordinate Voting Shares and Multiple Voting Shares under the Act, holders of Subordinate Voting Shares and Multiple Voting Shares shall be treated equally and identically, on a per share basis, unless different treatment of the shares of each such class is approved by a majority of the votes cast by the holders of outstanding Subordinate Voting Shares or their proxyholders in respect of a resolution approving such Change of Control Transaction and by a majority of the votes cast by the holders of outstanding Multiple Voting Shares or their proxyholders in respect of a resolution approving such Change of Control Transaction, each voting separately as a class at a meeting of the holders of that class called and held for such purpose. 8. 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 these Articles, but subject to the provisions of these Articles, holders of Subordinate Voting Shares shall be entitled to vote as a separate class, in addition to any other vote of shareholders that may be required, in respect of any alteration, repeal or amendment of these 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 these Articles that provides that any Multiple Voting Shares transferred, sold, assigned or exchanged to, or otherwise held by, a Person that is not a Permitted Holder shall be automatically converted into Subordinate Voting Shares, and such alteration, repeal or amendment shall not be effective unless a resolution in respect thereof is approved by a majority of the votes cast by holders of outstanding shares of such class or their proxyholders. 3.

Issuable in Series The Preferred Shares may be issued at any time or from time to time in one or more series.

whether such rate, amount, method of calculation or payment is subject to change or adjustment in the future; iii. voting rights, if any; any rights upon a dissolution, liquidation or winding-up of the Company or upon any other return of capital or distribution of the assets of the Company among its shareholders for the purpose of winding-up its affairs; iv. any rights of redemption, retraction or purchase for cancellation and the prices and terms and conditions of any such rights; v. vi. any rights of conversion, exchange or reclassification and the terms and conditions of any such rights, if applicable; and any other rights, privileges, restrictions and conditions, not inconsistent with these share provisions, attaching to such series of Preferred Shares. vii. No rights, privileges, restrictions or conditions attached to any series of Preferred Shares shall confer upon the shares of such series a priority in respect of dividends or distribution of assets or return of capital in the event of the liquidation, dissolution or winding-up of the Company over the shares of any other series of Preferred Shares. The Preferred Shares of each series shall, with respect to the right to payment of dividends and the distribution of assets or return of capital in the event of liquidation, dissolution or winding-up of the Company, rank on a parity with the shares of every other series. 2.

The holders of the class or a series of Preferred Shares shall not be entitled to vote separately as a class or series or to dissent upon a proposal to amend the articles of the Company to: increase or decrease any maximum number of authorized shares of such class or series, or increase any maximum number of authorized shares of a class or series having rights or privileges equal or superior to the shares of such class or series; i. ii. effect an exchange, reclassification or cancellation of all or part of the shares of such class or series; or iii. create a new class or series of shares equal or superior to the shares of such class or series.

to the Preferred Shares with respect to the payment of paid-up capital remaining after the payment of all outstanding debts on a pro rata basis, and the payment of any or all declared but unpaid cumulative dividends or any or all declared but unpaid dividends accrued on the Preferred Shares. The Preferred Shares may also be given such other preferences over the Subordinate Voting Shares, the Multiple Voting Shares and any other shares ranking junior to the Preferred Shares as may be fixed by directors’ resolution as to the respective series authorized to be issued. c. PROVISIONS ATTACHING TO THE SERIES A PERPETUAL CONVERTIBLE PREFERRED SHARES In addition to the rights, privileges, restrictions and conditions attaching to the preferred shares as a class, the Perpetual Convertible Preferred Shares shall have the following rights, privileges, restrictions and conditions (the “Perpetual Preferred Share Provisions”). Capitalized terms not defined where used shall have the meanings ascribed to such terms in SECTION 7. 1. Liquidation Preference. In the event of liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, or upon any other return of capital or distribution of the assets of the Company among its shareholders, in each case for the purposes of winding up its affairs (a “Liquidation Event”), each Perpetual Convertible Preferred Share entitles the holder thereof to receive and to be paid out of the assets of the Company available for distribution, before any distribution or payment may be made to a holder of any Subordinate Voting Shares or Multiple Voting Shares or any other shares ranking junior in such liquidation, dissolution or winding up to the Perpetual Convertible Preferred Shares, an amount per Perpetual Convertible Preferred Share equal to the greater of (i) the Liquidation Preference per Perpetual Convertible Preferred Share (as adjusted in accordance with SECTION 1(b)), and (ii) and the amount such holder would have received had they instead converted such Perpetual Convertible Preferred Share in accordance with SECTION 1(c) and SECTION 6(a) (in each case, the “Liquidation Amount”). a. The “Liquidation Preference” per Perpetual Convertible Preferred Share shall initially be equal to the Original Purchase Price. From and after the Original Issuance Date, the Liquidation Preference of each Perpetual Convertible Preferred Share shall automatically increase on a daily basis, on the basis of a 360 day year consisting of twelve 30 day months, as of immediately before the close of business on each such day, at a rate of (i) 7% per annum from, and including, the Original Issuance Date to, but excluding, September 30, 2027 ; (ii) at a rate of 8% per annum from, and including, September 30, 2027 to, but excluding, September 30, 2028; (iii) at a rate of 9% per annum from, and including September 30, 2028; and (iv) at a rate of 13% per annum if the conditions set forth in SECTION 5(b)(ii) are satisfied (as applicable, the “Accretion Rate”) of the then-applicable Liquidation Preference, the amount of which increase shall compound quarterly on each March 31, June 30, September 30 and December 31 (each, a “Quarterly Compounding Date”); provided that if Company elects (or is deemed to elect) to pay the Quarterly Redemption Price for the quarter ending on such Quarterly Compounding Date in cash in accordance with SECTION 5(c), the Accretion Rate for such quarter shall be 6% per annum. The Liquidation Preference shall be proportionally adjusted for any splits, combinations and similar events on the Perpetual Convertible Preferred Shares. b. For greater certainty, prior to any Liquidation Event, each holder of Perpetual Convertible Preferred Shares is entitled pursuant to SECTION 6(a), for a period of ten (10) Business Days following receipt of the written notice of such liquidation, dissolution or winding up, which shall be sent to the holders of the Perpetual Convertible Preferred Shares as soon as practicable, to convert any or all outstanding Perpetual Convertible Preferred Shares c.

held by such holder into, for each Perpetual Convertible Preferred Share held, a number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares equal to the then-applicable Conversion Amount and, subsequent to such conversion, such holder shall no longer be entitled to receive the Liquidation Preference with respect to any so converted Perpetual Convertible Preferred Shares. After payment to the holders of the Perpetual Convertible Preferred Shares of the full amount to which they are entitled in respect of outstanding Perpetual Convertible Preferred Shares pursuant to SECTION 1(a) (which, for greater certainty, have not been converted prior to such payment), such Perpetual Convertible Preferred Shares will have no further right or claim to any of the assets of the Company. d. In the case of any Liquidation Event, the Liquidation Preference shall be payable to holders of Perpetual Convertible Preferred Shares in cash; provided, however, that to the extent the Company has, having exercised commercial reasonable efforts to make such payment, insufficient cash available to pay the Liquidation Preference in full in cash, the portion of the Liquidation Preference with respect to which the Company has insufficient cash (and the remaining portion of the Liquidation Amount, if and to the extent the Liquidation Amount exceeds the Liquidation Preference) may be paid in property or other assets of the Company. The value of any property or assets not consisting of cash that is distributed by the Company in satisfaction of any portion of the Liquidation Amount will equal the Fair Market Value thereof on the date of distribution. e. 2. Voting Rights. The holders of the Perpetual Convertible Preferred Shares are entitled to receive notice of, attend and vote (in person or by proxy) at all meetings of the shareholders of the Company, except where holders of another class or series are entitled to vote separately as a class or series as provided in the Business Corporations Act (Ontario), applicable securities laws or the rules of any applicable stock exchange. Except as otherwise required by law, the holders of the Perpetual Convertible Preferred Shares, the Subordinate Voting Shares and the Multiple Voting Shares will vote together as a single class on all matters submitted to a vote of the shareholders of the Company. The Perpetual Convertible Preferred Shares shall confer the right to one (1) vote for each Perpetual Convertible Preferred Share held at all such meetings of shareholders of the Company. The holders of the Perpetual Convertible Preferred Shares shall not be entitled to vote separately as a class or series or to dissent upon a proposal to amend the articles of the Company to: (a) increase or decrease any maximum number of authorized Perpetual Convertible Preferred Shares, or increase any maximum number of authorized shares of a class having rights or privileges equal or superior to the Perpetual Convertible Preferred Shares; or (b) effect an exchange, reclassification or cancellation of the Perpetual Convertible Preferred Shares; or (c) create a new class of shares equal or superior to the Perpetual Convertible Preferred Shares. Each holder of Perpetual Convertible Preferred Shares shall be deemed to hold, for the sole purpose of voting at any meeting of shareholders of the Company at which such holder is entitled to vote, the number of Perpetual Convertible Preferred Shares equal to the number of whole Subordinate Voting Shares into which such holder’s registered Perpetual Convertible Preferred Shares are convertible pursuant to these share provisions as of the record date for the determination of shareholders entitled to vote at such shareholders meeting or, if no such record date is established, the date such vote is taken or any written resolution of shareholders is solicited. The holders of Perpetual Convertible Preferred Shares will be entitled to notice of all shareholders meetings or proposed actions by written consent as if such holders were holders of Subordinate Voting Shares. II. 3. Dividends. The holders of Perpetual Convertible Preferred Shares shall be entitled to receive only such dividends on the Perpetual Convertible Preferred Shares, if any, as are expressly declared thereon by the Board of Directors and shall not be entitled to any other dividends. The holders of Perpetual Convertible Preferred Shares shall not have the right to receive any dividends that are declared only with respect to the Subordinate Voting Shares or the Multiple Voting Shares, and nothing in these Perpetual Preferred Share Provisions will restrict the declaration or payment of any dividends on the Subordinate Voting Shares or the Multiple Voting Shares to the exclusion of the Perpetual Convertible Preferred Shares, provided, however, that the Company complies with the provisions of SECTION 6(e)(iii) in respect of an adjustment to the III.

Conversion Price in connection with any such dividend. 4. Purchase for Cancellation. Subject to such provisions of the Business Corporations Act (Ontario) as may be applicable, the Company may at any time or times purchase (if obtainable) for cancellation all or any part of the Perpetual Convertible Preferred Shares outstanding from time to time in one or more negotiated transactions at such price or prices as are determined by the Board of Directors and as may be agreed to with the relevant holders of the Perpetual Convertible Preferred Shares. From and after the date of purchase of any Perpetual Convertible Preferred Shares under the provisions of this SECTION 4, any shares so purchased shall be cancelled. IV. 5. Redemption. Except as expressly set out in this SECTION 5, the Company may not redeem any of the Perpetual Convertible Preferred Shares. a. (i) If a Change of Control occurs, then, the Company may elect, at its sole option, to redeem for cash all (but not less than all) of the then outstanding Perpetual Convertible Preferred Shares on the date (“Redemption Date”) that is twenty (20) Business Days following the effective date of the Change of Control at a price (the “Redemption Price”) per Perpetual Convertible Preferred Share equal to the greater of (i) an amount equal to (a) 105% of the Liquidation Preference as of the Redemption Date if such Change of Control occurs within five (5) years following the Original Issuance Date or (b) 100% of the Liquidation Preference as of the Redemption Date if such Change of Control occurs more than five (5) years after the Original Issuance Date; and (ii) the Fair Market Value of the consideration such holder would have received had such holder converted its Perpetual Convertible Preferred Shares in accordance with SECTION 6(a) with a Conversion Date immediately prior to the effective date of the Change of Control. The Company shall provide written notice (the “Redemption Notice”) of such redemption pursuant to this SECTION 5(b)(i), on the effective date of the Change of Control to the holders of record of the Perpetual Convertible Preferred Shares as they appear in the records of the Company. The Redemption Notice must state: (A) briefly, the events causing such Change of Control; (B) the effective date of such Change of Control; (C) the Redemption Price as of the Redemption Date, and the calculations supporting the specified Redemption Price; (D) the name and address of the transfer agent; (E) that the Perpetual Convertible Preferred Shares may be converted at any time before the Redemption Date; and (F) the procedures a holder must follow to require the Company to convert its Perpetual Convertible Preferred Shares, including the name and address of the place to where the Perpetual Convertible Preferred Shares are to be surrendered for payment of the Redemption Price. The Company shall, on the Redemption Date, pay the applicable Redemption Price, upon surrender of the certificates or DRS statement representing the Perpetual Convertible Preferred Shares to be redeemed. Perpetual Convertible Preferred Shares to be redeemed on the Redemption Date will, from and after such date, no longer be outstanding and the rights, privileges, restrictions and conditions attaching to the Perpetual Convertible Preferred Shares (except the right to receive from the Company the applicable Redemption Price) shall cease and terminate with respect to such shares; provided that in the event that a Perpetual Convertible Preferred Share is not redeemed due to a default in payment by the Company, such Perpetual Convertible Preferred Share will remain outstanding and will be entitled to all rights, privileges, restrictions and conditions attaching to the Perpetual Convertible Preferred Shares as provided herein (including continued increases in Liquidation Preference at the applicable Accretion Rate). For greater certainty, the holders of the Perpetual Convertible Preferred Shares may, at any time prior to the Redemption Date, elect to convert any or all of their Perpetual Convertible Preferred Shares pursuant to SECTION 6(a). To the extent the Perpetual Convertible Preferred Shares are not redeemed or converted in connection with a Change of Control in accordance with this SECTION 5(b)(i) , such Perpetual Convertible Preferred Shares shall remain outstanding in accordance with their terms following such Change of Control b. • V.

(subject to any adjustments as may be required pursuant to SECTION 6(e)(v)). (ii) In the event that the Company does not elect to redeem for cash all (but not less than all) of the then outstanding Perpetual Convertible Preferred Shares on the Redemption Date pursuant to SECTION 5(b)(i), then the Accretion Rate shall automatically increase to 13% on and after the date on which such Change of Control occurs for purposes of SECTION 1(b)(iv). • (iii) For greater certainty, if a Change of Control occurs and results (or upon a completion would result) in a Change of Control, then, prior to the Redemption Date, each holder of Perpetual Convertible Preferred Shares is entitled to convert, including prior to the occurrence of the Change of Control and in order to participate therein as a holder of Subordinate Voting Shares, at the option and election of such holder, any or all of the outstanding Perpetual Convertible Preferred Shares held by such holder into Subordinate Voting Shares pursuant to SECTION 6(a). • Quarterly Redemption by the Company. (i) On December 31, 2024 and on each Quarterly Compounding Date thereafter (each a “Quarterly Redemption Date”), at the Company’s option and election and upon its compliance with this SECTION 5(c)(i), the Company may redeem, on a pro rata basis if there is more than one holder, such number of the then outstanding Perpetual Convertible Preferred Shares having an aggregate Liquidation Preference equal to the product of: (A) one quarter (1/4) of the applicable Accretion Rate for the quarter ending on the Quarterly Redemption Date, and (B) the aggregate Liquidation Preference of all of the then outstanding Perpetual Convertible Preferred Shares (rounded to the nearest whole number) as of the applicable Quarterly Redemption Date, at a price (the “Quarterly Redemption Price”) per Perpetual Convertible Preferred Share equal to the Liquidation Preference as of the applicable Quarterly Redemption Date. The Quarterly Redemption Price shall be paid, at the election of the Company, in cash or, if the Liquidity Conditions are satisfied, by issuing to the holder(s) such number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares determined per Perpetual Convertible Preferred Share so redeemed by dividing (i) the Quarterly Redemption Price by (ii) 97% of the Current Market Price of the Subordinate Voting Shares on the date of the applicable Quarterly Redemption Notice. The Company shall provide written notice (the “Quarterly Redemption Notice”) to the holders of record of the Perpetual Convertible Preferred Shares as they appear in the records of the Company pursuant to this SECTION 5(c)(i), on or prior to the fifth (5th) Business Day prior to each Quarterly Redemption Date.

(ii) If the Company elects to pay the Quarterly Redemption Price in Subordinate Voting Shares, no fractional Subordinate Voting Shares will be issued upon the payment of the Quarterly Redemption Price. In lieu of fractional shares, the Company shall, subject to the last sentence hereof, round to the nearest whole number, the number of Subordinate Voting Shares to be issued upon payment of the applicable Quarterly Redemption Price. If more than one Perpetual Convertible Preferred Share is being redeemed at one time by or for the benefit of the same holder, then the number of full Subordinate Voting Shares issuable upon such redemption will be calculated on the basis of the aggregate number of Perpetual Convertible Preferred Shares redeemed by or for the benefit of such holder at such time. • Optional Redemption by the Company. (i) On and after the five (5) year anniversary of the Original Issuance Date, at the Company’s option and election and upon its compliance with this SECTION 5(d)(i), all (but not less than all) of the then outstanding Perpetual Convertible Preferred Shares may be redeemed at a price (the “Optional Redemption Price”) per Perpetual Convertible Preferred Share equal to (a) 105% of the Liquidation Preference as of the Optional Redemption Date if such redemption occurs prior to the six (6) year anniversary of the Original Issuance Date; (b) 103% of the Liquidation Preference as of the Optional Redemption Date if such redemption occurs after the six (6) year anniversary of the Original Issuance Date and prior to the seven (7) year anniversary of the Original Issuance Date; or (c) 100% of the Liquidation Preference as of the Optional Redemption Date if such redemption occurs after the seven (7) year anniversary of the Original Issuance Date. The Company shall provide written notice (the “Optional Redemption Notice”) of such redemption pursuant to this SECTION 5(d), no less than ten (10) days and no more than sixty (60) days prior to the date set for the redemption (the “Optional Redemption Date”) to the holders of record of the Perpetual Convertible Preferred Shares as they appear in the records of the Company. The Optional Redemption Notice must state: (A) that the Perpetual Convertible Preferred Shares have been called for redemption and, briefly, the optional redemption right; (B) the Optional Redemption Price as of the Optional Redemption Date, and the calculations supporting the specified Optional Redemption Price, (C) that the Perpetual Convertible Preferred Shares may be converted at any time before the Optional Redemption Date; (D) the name and address of the transfer agent; and (E) the name and address of the place to where the Perpetual Convertible Preferred Shares are to be surrendered for payment of the Optional Redemption Price.

Preferred Shares may, at any time prior to the Optional Redemption Date, elect to convert any or all of their Perpetual Convertible Preferred Shares pursuant to SECTION 6(a). VI. 6. Conversion. Each Perpetual Convertible Preferred Share is convertible into Subordinate Voting Shares as provided in this SECTION 6. Conversion at the Option of Holders of Perpetual Convertible Preferred Shares. Each holder of Perpetual Convertible Preferred Shares is entitled to convert, at any time and from time to time, at the option and election of such holder, any or all outstanding Perpetual Convertible Preferred Shares held by such holder into a number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares equal to the number (the “Conversion Amount”) determined per each Perpetual Convertible Preferred Share so converted by dividing (i) the Liquidation Preference (as adjusted pursuant to SECTION 1(b) to the applicable Conversion Date) for each Perpetual Convertible Preferred Share to be converted by (ii) the Conversion Price (which Conversion Price shall be adjusted from time to time as provided in SECTION 6(e)) in effect on the Conversion Date. The “Conversion Price” is initially US$25.20, as adjusted from time to time as provided in SECTION 6(e). In order to convert the Perpetual Convertible Preferred Shares into Subordinate Voting Shares pursuant to this SECTION 6(a), the holder must surrender the certificates or DRS statements representing such Perpetual Convertible Preferred Shares, accompanied by transfer instruments reasonably satisfactory to the Company, at the office of the Company or its transfer agent for the Perpetual Convertible Preferred Shares (as directed by the Company), together with the prescribed form of written notice, set forth on the Perpetual Convertible Preferred Share certificates or DRS statement, that such holder elects to convert all or such number of shares represented by such certificates or DRS statement as specified therein. Notwithstanding the foregoing, the right of conversion may be exercised as to any portion of such holder’s Perpetual Convertible Preferred Shares from time to time; provided that, in each case, no right of conversion may be exercised by a holder in respect of fewer than 47,619 Perpetual Convertible Preferred Shares (unless such conversion is in respect of all Perpetual Convertible Preferred Shares held by such holder). a. Conversion at the Option of the Company. (i) If the Liquidity Conditions are satisfied, on and after the three (3) year anniversary of the Original Issuance Date, at the Company’s option and election and upon its compliance with this SECTION 6(b)(i), all (but not less than all) outstanding Perpetual Convertible Preferred Shares shall be converted into a number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares equal to the then-applicable Conversion Amount per each Perpetual Convertible Preferred Share so converted, upon written notice by the Company to holders of record of the Perpetual Convertible Preferred Shares as they appear in the records of the Company notifying such holders of the conversion contemplated by this SECTION 6(b)(i), which conversion shall occur on the tenth (10th) Business Day following the date of such notice, which Conversion Date shall be specified in such notice, provided, that such notice may be delivered by the Company (and such Perpetual Convertible Preferred Shares may be converted into Subordinate Voting Shares pursuant to this SECTION 6(b)(i)) only if the Closing Price (or, if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) per Subordinate Voting Share for at least twenty (20) Trading Days during any period of thirty (30) consecutive Trading Days ending on, and including, the Trading Day immediately before the date on which such notice is delivered by the Company was equal to or greater than (x) at least 160% of the Conversion Price if such conversion occurs after the three (3) year anniversary of the Original Issuance Date and prior to the four (4) year anniversary of the Original Issuance Date; (y) at least 150% of the Conversion Price if such conversion occurs after the four (4) year anniversary of the Original Issuance Date and prior to the five (5) year anniversary of the Original Issuance Date; and (z) at least 140% of the Conversion Price if such • b.

(ii) Such notice of conversion at the option of the Company pursuant to SECTION 6(b)(i) must state: that the Company has exercised its conversion right pursuant to SECTION 6(b)(i), briefly describing such conversion right; A. the Conversion Date for such conversion and the date scheduled for the settlement of such conversion; B. C. the name and address of the transfer agent; that Perpetual Convertible Preferred Shares subject to conversion pursuant to SECTION 6(b)(i) may be converted earlier at the option of the holders thereof pursuant to SECTION 6(a) at any time before such Conversion Date; and D. E. the Conversion Price in effect on such Conversion Date. • Fractional Shares. No fractional Subordinate Voting Shares will be issued upon conversion of the Perpetual Convertible Preferred Shares. In lieu of fractional shares the Company shall, subject to the last sentence hereof, round to the next whole number, the number of Subordinate Voting Shares to be issued upon conversion of the Perpetual Convertible Preferred Shares. If more than one Perpetual Convertible Preferred Share is being converted at one time by or for the benefit of the same holder, then the number of full Subordinate Voting Shares issuable upon conversion will be calculated on the basis of the aggregate number of Perpetual Convertible Preferred Shares converted by or for the benefit of such holder at such time, and if all of the Perpetual Convertible Preferred Shares held by a holder are being converted at the same time, then the number of full Subordinate Voting Shares issuable upon conversion will be calculated on the basis of the aggregate number of Perpetual Convertible Preferred Shares converted by or for the benefit of such holder at such time, with any resulting fractional entitlement being rounded to the nearest whole number. c. Mechanics of Conversion. (i) On the second Business Day immediately succeeding the Conversion Date, the Company shall issue and deliver to each holder of Perpetual Convertible Preferred Shares the number of Subordinate Voting Shares to which such holder is entitled in exchange for the certificates or DRS statement formerly representing Perpetual Convertible Preferred Shares. Such conversion will be deemed to have been made on the Conversion Date, and the person entitled to receive the Subordinate Voting Shares issuable upon such conversion shall be treated for all purposes as the record holder of such Subordinate Voting Shares on such Conversion Date. In case fewer than all the Perpetual Convertible Preferred Shares represented by any certificate or DRS statement are to be converted, a new certificate or DRS statement shall be issued representing the unconverted Perpetual Convertible Preferred Shares without cost to the holder thereof, except for any documentary, stamp or similar issue or transfer tax due because any certificates DRS statement for Subordinate Voting Shares or Perpetual Convertible Preferred Shares are registered in a name other than the name of the converting holder. The Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Subordinate Voting Shares upon conversion or due upon the issuance of a new certificate or DRS statement for any Perpetual Convertible Preferred Shares not converted other than any such tax due because Subordinate Voting Shares or a certificate DRS statement for Perpetual Convertible Preferred Shares are issued in a name other than the name of the converting • d.

holder, which shall be paid by the converting holder. (ii) From and after the Conversion Date, the Perpetual Convertible Preferred Shares to be converted on such Conversion Date will no longer be outstanding, and all rights and privileges of the holder thereof as a holder of Perpetual Convertible Preferred Shares (except the right to receive from the Company the Subordinate Voting Shares upon conversion) shall cease and terminate with respect to such shares. • (iii) All Subordinate Voting Shares issued upon conversion of the Perpetual Convertible Preferred Shares will, upon issuance by the Company, be duly and validly issued, as fully paid and non-assessable Subordinate Voting Shares in the capital of the Company. • Adjustments to Conversion Price. (i) Adjustments for issuances of subordinate voting shares, share splits and share combinations. If the Company shall, at any time and from time to time while any Perpetual Convertible Preferred Shares are outstanding, issue Subordinate Voting Shares as a dividend or distribution to all or substantially all holders of its Subordinate Voting Shares or the Company shall effect a share split or share combination of Subordinate Voting Shares into a greater or lesser number of Subordinate Voting Shares (in each case excluding an issuance solely pursuant to a Capital Reorganization, as to which SECTION 6(e)(vi) will apply), then the then-applicable Conversion Price will be adjusted in accordance with the following formula: • e. where CP0 = the Conversion Price in effect immediately prior to the close of business on the Record Date for such dividend or distribution or immediately prior to the open of business on the Effective Date for such share split or share combination, as the case may be; CP1 = the Conversion Price in effect immediately after the close of business on such Record Date or immediately after the open of business on such Effective Date, as the case may be; OS0 = the number of Subordinate Voting Shares outstanding immediately prior to the close of business on such Record Date or immediately prior to the open of business on such Effective Date, as the case may be (in either case, prior to giving effect to such event); and OS1 = the number of Subordinate Voting Shares that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split or share combination. Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(i) shall become effective immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as the case may be. If any dividend or distribution of the type described in this SECTION 6(e)(i) is declared but not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to make such dividend or distribution, to such Conversion Price that would be in effect if such dividend or distribution had not been declared. For the purposes of this SECTION 6(e)(i), the number of Subordinate Voting Shares outstanding immediately prior to the close of business on the Record Date for such dividend or distribution or the open of business on the Effective Date for such share split or share combination, as applicable, shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

scrip certificates issued in lieu of fractions of Subordinate Voting Shares. The Company shall not pay any such dividend or make any such distribution on Subordinate Voting Shares held in treasury by the Company. (ii) Adjustments for certain rights, options and warrants. If the Company shall, at any time or from time to time, while any Perpetual Convertible Preferred Shares are outstanding, issue to all or substantially all holders of Subordinate Voting Shares rights, options or warrants (other than rights issued pursuant to a shareholder rights plan, as to which SECTION 6(e)(iv)(B) and SECTION 6(e)(xii) will apply) entitling such holders, for a period of up to 45 calendar days from the date of issuance of such rights, options or warrants, to subscribe for or purchase Subordinate Voting Shares at a price per share less than the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, then the then-applicable Conversion Price shall be adjusted based on the following formula: ○ CP1=CP0 x (OS0+Y)(OS0+X) where, CP0 = the Conversion Price in effect immediately prior to the opening of business on the Record Date for such issuance; CP1 = the Conversion Price in effect immediately after the close of business on such Record Date; OS0 = the number of Subordinate Voting Shares outstanding immediately prior to the close of business on such Record Date; X = the total number of Subordinate Voting Shares issuable pursuant to such rights, options or warrants; and Y = the total number of Subordinate Voting Shares equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance. Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(ii) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the close of business on the Record Date for such issuance. In the event that such rights, options or warrants described in this clause (ii) are not so issued, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to issue such rights, options or warrants, to such Conversion Price that would then be in effect if such issuance had not been declared. To the extent that such rights, options or warrants are not exercised prior to their expiration or Subordinate Voting Shares are otherwise not delivered pursuant to such rights, options or warrants upon the exercise of such rights, options or warrants, the Conversion Price shall be readjusted, effective as of the date of such expiration or the date it is determined such shares will not be delivered, as the case may be, to such Conversion Price that would then be in effect had the adjustment made upon the issuance of such rights, options or warrants been made on the basis of the delivery of only the number of Subordinate Voting Shares actually delivered.

In determining whether any rights, options or warrants entitle the holders thereof to subscribe for or purchase Subordinate Voting Shares at less than the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. For the purposes of this SECTION 6(e)(ii), the number of Subordinate Voting Shares at the time outstanding shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of Subordinate Voting Shares. The Company shall not issue any such rights, options or warrants in respect of Subordinate Voting Shares held in treasury by the Company. (iii) Adjustments for Payment of Cash Dividends. If the Company makes a dividend or distribution consisting exclusively of cash to all or substantially all holders of Subordinate Voting Shares (excluding (1) any regular quarterly dividend that does not exceed US$0.01 per Subordinate Voting Share (“Dividend Threshold Amount”), (2) any cash that is distributed in, and will constitute Reference Property as a result of, a Capital Reorganization in exchange for Subordinate Voting Shares and (3) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company), then the Conversion Price shall be adjusted based on the following formula: ○ CP1=CP0 x (SP0-C)(SP0-T) where, CP0 = the Conversion Price in effect immediately prior to the close of business on the Record Date for such dividend or distribution; CP1 = the Conversion Price in effect immediately after the close of business on the Record Date for such dividend or distribution; SP0 = the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such dividend or distribution; T = the Dividend Threshold Amount; provided that if the dividend or distribution is not a regular quarterly cash dividend, the Dividend Threshold Amount shall be deemed to be zero; and C = the amount in cash per share the Company distributes to holders of Subordinate Voting Shares. The Dividend Threshold Amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted, but no adjustment shall be made to the Dividend Threshold Amount for any adjustment made to the Conversion Price pursuant to this SECTION 6(e)(iii).

Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(iii) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. If any dividend or distribution of the type described in this SECTION 6(e)(iii) is declared but not so paid or made, the Conversion Price shall again be adjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing decrease, each holder of Perpetual Convertible Preferred Shares shall receive at the same time and upon the same terms as holders of Subordinate Voting Shares, the amount of cash as a dividend on the Perpetual Convertible Preferred Shares that such holder would have received if such holder owned a number of Subordinate Voting Shares at the Conversion Price in effect immediately prior to the close of business on the Record Date for such cash dividend or distribution. ○ (iv) Adjustments for certain distributions. (A) If the Company shall, at any time and from time to time while any Perpetual Convertible Preferred Shares are outstanding, distribute to all or substantially all holders of the Subordinate Voting Shares any shares of Capital Stock (other than Subordinate Voting Shares), evidences of the Company’s indebtedness, assets or rights, options or warrants to acquire Capital Stock, indebtedness or assets (excluding (1) any dividend or distribution (including share splits or share combinations) as to which an adjustment was effected pursuant to SECTION 6(e)(i), (2) any rights, options or warrants as to which an adjustment was effected pursuant to Section 6(e)(ii), (3) except as otherwise described in SECTION 6(e)(xiii), rights issued pursuant to any shareholder rights plan of the Company then in effect, (4) any dividend or distribution described in SECTION 6(e)(iii), (5) distributions of Reference Property in a transaction described in SECTION 6(e)(vi) and (6) any Spin-Off to which the provisions set forth in SECTION 6(e)(iv)(B) shall apply, then the applicable Conversion Price will be adjusted based on the following formula: CP1=CP0 x (SP0-FMV)SP0 where, CP0 = the Conversion Price in effect immediately prior to the close of business on the Record Date for such dividend or distribution; CP1 = the Conversion Price in effect immediately after the close of business on such Record Date; SP0 = the average of the Closing Prices per Subordinate Voting Share for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such dividend or distribution; and FMV = the Fair Market Value on such Record Date of the shares, evidences of indebtedness, assets or rights, options or warrants so distributed, expressed as an amount per Subordinate Voting Share. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing decrease, each holder of Perpetual Convertible Preferred Shares shall receive at the same time and upon the same terms as holders of Subordinate Voting Shares, the kind and amount of the Company’s shares, evidences of indebtedness, assets or rights, options or warrants that such holder would have received if such holder owned a number of Subordinate Voting Shares at the Conversion Price in effect immediately prior to the close of BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

business on the Record Date for such dividend or distribution. Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(iv)(A) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. In the event that such distribution described in this SECTION 6(e)(iv)(A) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such distribution, to the Conversion Price that would then be in effect if such dividend or distribution had not been announced. (B) In a Spin-Off, the Conversion Price will be adjusted based on the following formula: CP1=CP0 x MP0(FMV0+MP0) where, CP0 = the Conversion Price in effect immediately prior to the open of business on the Ex-Date for the Spin-Off; CP1 = the Conversion Price in effect immediately after the open of business on the Ex-Date for the Spin-Off; FMV0 = the average of the Closing Prices (as if references to “Subordinate Voting Shares” therein were references to such shares or similar equity interest distributed to holders of Subordinate Voting Shares) of the shares or similar equity interests so distributed applicable to one Subordinate Voting Share for the 10 consecutive Trading Day period commencing on, and including, the Ex-Date for the Spin-Off (the “Valuation Period”); and MP0 = the average of the Closing Prices per Subordinate Voting Share for the Valuation Period. Any adjustment made pursuant to this clause (vi)(B) will be calculated immediately after the close of business on the last Trading Day of the Valuation Period but shall be given effect as of immediately after the open of business on the Ex-Date for the Spin-Off; provided that, if any Conversion Date occurs during the Valuation Period, the Company shall, to the extent necessary, delay any settlement of such conversion until the second Business Day after the last day of the Valuation Period. In the event that such distribution described in this clause (vi)(B) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such distribution, to the Conversion Price that would then be in effect if such distribution had not been announced. The Company shall not make any such dividend or distribution on Subordinate Voting Shares held in treasury by the Company. (v) Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries successfully completes a tender offer or exchange offer for Subordinate Voting Shares (other than a normal course issuer bid under applicable Canadian securities laws) where the cash and the value of any other consideration included in the payment per Subordinate Voting Share validly tendered or exchanged exceeds the average of the Closing Prices per Subordinate Voting Share for the 10 consecutive Trading Day period (the “Averaging Period”) commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “Tender Offer Expiration Date”), then the Conversion Price will be adjusted based on the following formula: ○ BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

CP1=CP0 x (SP0 x OS0)AC+(SP0 x OS1) where, CP0 = the Conversion Price in effect immediately prior to the close of business on the Tender Offer Expiration Date; CP1 = the Conversion Price in effect immediately after the close of business on the Tender Offer Expiration Date; SP0 = the average of the Closing Prices per Subordinate Voting Share over the Averaging Period; OS0 = the number of Subordinate Voting Shares outstanding immediately prior to the Tender Offer Expiration Date, prior to giving effect to the purchase of any shares accepted for purchase or exchange in such tender offer or exchange offer; AC = the aggregate value of all cash and the Fair Market Value (as determined by the Board of Directors) on the Tender Offer Expiration Date of any other consideration paid or payable for Subordinate Voting Shares acquired pursuant to such tender offer or exchange offer; and OS1 = the number of Subordinate Voting Shares outstanding immediately after the Tender Offer Expiration Date, after giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer. The Conversion Price will in no event be adjusted up pursuant to this SECTION 6(e)(v), except to the extent provided in the last sentence of this paragraph. Any adjustment to the Conversion Price pursuant to this SECTION 6(e)(v) will be calculated as of the close of business on the last Trading Day of the Averaging Period, but shall be given effect immediately after the close of business on the Tender Offer Expiration Date; provided that, if any Conversion Date occurs during the Averaging Period, the Company shall, if necessary, delay any settlement of such conversion until the second Business Day after the last day of the Averaging Period. If the Company or one of its Subsidiaries is obligated to purchase Subordinate Voting Shares pursuant to any such tender or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Price shall be readjusted to be such Conversion Price that would then be in effect if such tender or exchange offer had not been made. (vi) Capital Reorganization Events. In the case of: any consolidation, amalgamation or merger of the Company with or into another Person (other than a merger, amalgamation or consolidation in which the Company is the continuing or surviving corporation and in which the Subordinate Voting Shares outstanding immediately prior to the merger, amalgamation or consolidation are not exchanged for cash, securities or other property of the Company or another Person); A. any direct or indirect sale, lease, assignment, transfer or conveyance of all or substantially all of the Company’s consolidated property or assets; B. any reclassification of Subordinate Voting Shares into securities, including securities other than the Subordinate Voting Shares (other than changes in par value, if any, or resulting from a subdivision or combination); or C. ○ BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition); D. in each case, as a result of which the Subordinate Voting Shares would be converted into, or exchanged for, securities, cash or other property (each, a “Capital Reorganization”), then, at and after the effective time of such Capital Reorganization, the right to exchange each Perpetual Convertible Preferred Share shall be changed into a right to exchange such share into the kind and amount of shares, cash, other securities or other property or assets (or any combination thereof) that a holder of a number of Subordinate Voting Shares equal to the Conversion Amount (with respect to such Perpetual Convertible Preferred Share) immediately prior to such Capital Reorganization would have owned or been entitled to receive upon such Capital Reorganization (such shares, securities or other property or assets, the “Reference Property”, with each unit of Reference Property being the kind and amount of Reference Property that a holder of one Subordinate Voting Share would have received in such Capital Reorganization). Prior to or at the effective time of such Capital Reorganization, the Company or the successor or purchasing person, as the case may be, shall execute and deliver such supplemental instruments, if any, as the Company reasonably determines are necessary or desirable to (1) provide for subsequent adjustments to the Conversion Price pursuant to SECTION 6(e) in a manner consistent with this SECTION 6(e)(vi) (including giving effect, in the Company’s reasonable discretion, to the Dividend Threshold Amount in a manner that preserves the economic interests of the holders); and (2) give effect to such other provisions, if any, as the Company reasonably determines are appropriate to preserve the economic interests of the holders. If the Reference Property includes shares of stock or other securities or assets of a person other than such successor person, then such other person will also execute such supplemental instrument(s) and such supplemental instrument(s) will contain such additional provisions, if any, that the Company reasonably determines are appropriate to preserve the economic interests of holders. In each case, if a Capital Reorganization causes the Subordinate Voting Shares to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), then the Reference Property into which the Perpetual Convertible Preferred Shares will be exchangeable shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Subordinate Voting Shares. The Company shall notify the holders of the Perpetual Convertible Preferred Shares of such weighted average as soon as practicable after such determination is made. For these purposes, the Closing Price of any unit of Reference Property or portion thereof that does not consist of a class of securities will be the fair value of such unit of Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof). None of the foregoing provisions shall affect (x) the right of a holder of Perpetual Convertible Preferred Shares to convert its Perpetual Convertible Preferred Shares (1) into Subordinate Voting Shares prior to the effective time of such Capital Reorganization or (2) into Subordinate Voting Shares or Reference Property, as applicable, following the effective time of such Capital Reorganization, in any case pursuant to SECTION 6(a), or, (y) if the event constituting a Capital Reorganization is also a Change of Control, the obligation of the Company to redeem the Perpetual Convertible Preferred Shares in connection with such transaction pursuant to SECTION 5. The provisions of this SECTION 6(e)(vi) shall similarly apply to successive Capital Reorganization events. This SECTION 6(e)(vi) shall not apply to any share split or combination to which SECTION 6(e)(i) is applicable or to a Liquidation Event. (vii) The Company shall not enter into any agreement for a transaction constituting a Capital Reorganization unless its terms are consistent with SECTION 6(e)(vi). ○ (viii) Minimum Adjustment. Notwithstanding the foregoing, the Conversion Price will not be reduced if the amount of such reduction would be an amount less than US$0.01, but any such amount will be carried forward and reduction with respect thereto will be made (1) at the time that such amount, together with any subsequent amounts so carried forward, aggregates to US$0.01 or more; (2) upon the Conversion Date of any Perpetual Convertible Preferred Share; (3) upon the date a Change of Control occurs; and (4) upon ○ BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

G. for a third-party tender offer; upon the issuance of any Subordinate Voting Shares pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Original Issuance Date; or H. for any other issuance of Subordinate Voting Shares or any securities convertible into or exchangeable for Subordinate Voting Shares or the right to purchase Subordinate Voting Shares or such convertible or exchangeable securities, except as described above or below. A. ○ (x) Rules of Calculation. All calculations will be made to the nearest one-hundredth of a cent or to the nearest one-ten thousandth of a share. Except as explicitly provided herein, the number of Subordinate Voting Shares outstanding will be calculated on the basis of the number of issued and outstanding Subordinate Voting Shares. ○ (xi) Waiver. Notwithstanding anything in this SECTION 6(e) to the contrary, no adjustment need be made to the Conversion Price for any event with respect to which an adjustment would otherwise be required pursuant to this SECTION 6(e) if the Company receives, prior to the effective time of the adjustment to the Conversion Price, written notice from the holders representing at least a majority of the then outstanding Perpetual Convertible Preferred Shares that no adjustment is to be made as the result of a particular ○ BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

This waiver will be limited in scope and will not be valid for any issuance of Subordinate Voting Shares or other dividend or other distribution on Subordinate Voting Shares or any other event not specifically provided for in such notice. (xii) Shareholder Rights Plans. To the extent that the Company has a rights plan in effect with respect to the Subordinate Voting Shares on any Conversion Date, Holders shall receive, in addition to the Subordinate Voting Shares, the rights under the rights plan, unless, prior to such Conversion Date, the rights have separated from the Subordinate Voting Shares, in which case the Conversion Price shall be adjusted at the time of separation as if the Company made a distribution to all holders of the Subordinate Voting Shares as described in SECTION 6(e)(iv)(A), subject to readjustment in the event of the expiration, termination or redemption of such rights. ○ (xiii) Reservation of Shares. For the purpose of effecting the conversion of Perpetual Convertible Preferred Shares, the Company shall at all times reserve and keep available, free from any preemptive rights, out of its treasury or authorized but unissued Subordinate Voting Shares the full number of Subordinate Voting Shares deliverable upon the conversion of all outstanding Perpetual Convertible Preferred Shares after taking into account any adjustments to the Conversion Price from time to time pursuant to the terms of this SECTION 6 and any increases to the Liquidation Preference from time to time and assuming for the purposes of this calculation that all outstanding Perpetual Convertible Preferred Shares are held by one holder. All Subordinate Voting Shares delivered upon conversion of Perpetual Convertible Preferred Shares shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests and other encumbrances (other than liens, charges, security interests and other encumbrances created by the holders) and free of preemptive rights. If the Subordinate Voting Shares are then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will cause each such Subordinate Voting Share, when so delivered, to be admitted for listing on such exchange or quotation on such system. ○ (xiv) Successive Adjustments. For the avoidance of doubt, after an adjustment to the Conversion Price under this SECTION 6, any subsequent event requiring an adjustment under this SECTION 6 shall cause an adjustment to such Conversion Price as so adjusted. ○ Certificate of Adjustments. Promptly upon the occurrence of any event requiring an adjustment or readjustment of the Conversion Price pursuant to this SECTION 6, the Company shall compute such adjustment or readjustment in accordance with the terms hereof and, within five (5) Business Days of such event, provide to each holder of Perpetual Convertible Preferred Shares a notice setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a brief description of the transaction or other event and the effective time of such adjustment. The Company shall, upon the reasonable written request of any holder of Perpetual Convertible Preferred Shares, furnish to such holder (i) the calculation of such adjustments and readjustments in reasonable detail, (ii) the Conversion Price then in effect, and (iii) the number of Subordinate Voting Shares and the amount, if any, of share capital, other securities or other property (including, but not limited to, cash and evidences of indebtedness) which then would be received upon the conversion of Perpetual Convertible Preferred Shares. • 7.

PROVISIONS ATTACHING TO THE SERIES B PERPETUAL CONVERTIBLE PREFERRED SHARES In addition to the rights, privileges, restrictions and conditions attaching to the preferred shares as a class, the Series B Perpetual Convertible Preferred Shares shall have the following rights, privileges, restrictions and conditions (the “Series B Perpetual Preferred Share Provisions”). Capitalized terms not defined where used shall have the meanings ascribed to such terms in SECTION 7. 1. Liquidation Preference. In the event of liquidation, dissolution or winding up of the Company, whether voluntary or involuntary, or upon any other return of capital or distribution of the assets of the Company among its shareholders, in each case for the purposes of winding up its affairs (a “Liquidation Event”), each Series B Perpetual Convertible Preferred Share entitles the holder thereof to receive and to be paid out of the assets of the Company available for distribution, before any distribution or payment may be made to a holder of any Subordinate Voting Shares or Multiple Voting Shares or any other shares ranking junior in such liquidation, dissolution or winding up to the Series B Perpetual Convertible Preferred Shares, an amount per Series B Perpetual Convertible Preferred Share equal to the greater of (i) the Liquidation Preference per Series B Perpetual Convertible Preferred Share (as adjusted in accordance with SECTION 1(b)), and (ii) and the amount such holder would have received had they instead converted such Series B Perpetual Convertible Preferred Share in accordance with SECTION 1(c) and SECTION 6(a) (in each case, the “Liquidation Amount”). a. The “Liquidation Preference” per Series B Perpetual Convertible Preferred Share shall initially be equal to the Original Purchase Price. From and after the Original Issuance Date, the Liquidation Preference of each Series B Perpetual Convertible Preferred Share shall automatically increase on a daily basis, on the basis of a 360 day year consisting of twelve 30 day months, as of immediately before the close of business on each such day, at a rate of (i) 6.0% per annum from, and including, the Original Issuance Date to, but excluding, December 17, 2028; (ii) at a rate of 7.0% per annum from, and including, December 17, 2028 to, but excluding, December 17, 2029; (iii) at a rate of 8.0% per annum from, and December 17, 2029; and (iv) at a rate of 13% per annum if the conditions set forth in SECTION 5(b)(ii) are satisfied (as applicable, the “Accretion Rate”) of the then-applicable Liquidation Preference, the amount of which increase shall compound quarterly on each March 31, June 30, September 30 and December 31 (each, a “Quarterly Compounding Date”); provided that if Company elects (or is deemed to elect) to pay the Quarterly Redemption Price for the quarter ending on such Quarterly Compounding Date in cash in accordance with SECTION 5(c), the Accretion Rate for such quarter shall be 5% per annum. The Liquidation Preference shall be proportionally adjusted for any splits, combinations and similar events on the Series B Perpetual Convertible Preferred Shares. b. For greater certainty, prior to any Liquidation Event, each holder of Series B Perpetual Convertible Preferred Shares is entitled pursuant to SECTION 6(a), for a period of ten (10) Business Days following receipt of the written notice of such liquidation, dissolution or winding up, which shall be sent to the holders of the Series B Perpetual Convertible Preferred Shares as soon as practicable, to convert any or all outstanding Series B Perpetual Convertible Preferred Shares held by such holder into, for each Series B Perpetual Convertible Preferred Share c.

held, a number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares equal to the then-applicable Conversion Amount and, subsequent to such conversion, such holder shall no longer be entitled to receive the Liquidation Preference with respect to any so converted Series B Perpetual Convertible Preferred Shares. After payment to the holders of the Series B Perpetual Convertible Preferred Shares of the full amount to which they are entitled in respect of outstanding Series B Perpetual Convertible Preferred Shares pursuant to SECTION 1(a) (which, for greater certainty, have not been converted prior to such payment), such Series B Perpetual Convertible Preferred Shares will have no further right or claim to any of the assets of the Company. d. In the case of any Liquidation Event, the Liquidation Preference shall be payable to holders of Series B Perpetual Convertible Preferred Shares in cash; provided, however, that to the extent the Company has, having exercised commercial reasonable efforts to make such payment, insufficient cash available to pay the Liquidation Preference in full in cash, the portion of the Liquidation Preference with respect to which the Company has insufficient cash (and the remaining portion of the Liquidation Amount, if and to the extent the Liquidation Amount exceeds the Liquidation Preference) may be paid in property or other assets of the Company. The value of any property or assets not consisting of cash that is distributed by the Company in satisfaction of any portion of the Liquidation Amount will equal the Fair Market Value thereof on the date of distribution. e. 2. Voting Rights. The holders of the Series B Perpetual Convertible Preferred Shares are entitled to receive notice of, attend and vote (in person or by proxy) at all meetings of the shareholders of the Company, except where holders of another class or series are entitled to vote separately as a class or series as provided in the Business Corporations Act (Ontario), applicable securities laws or the rules of any applicable stock exchange. Except as otherwise required by law, the holders of the Series B Perpetual Convertible Preferred Shares, the Perpetual Convertible Preferred Shares, the Subordinate Voting Shares and the Multiple Voting Shares will vote together as a single class on all matters submitted to a vote of the shareholders of the Company. The Series B Perpetual Convertible Preferred Shares shall confer the right to one (1) vote for each Series B Perpetual Convertible Preferred Share held at all such meetings of shareholders of the Company.

Each holder of Series B Perpetual Convertible Preferred Shares shall be deemed to hold, for the sole purpose of voting at any meeting of shareholders of the Company at which such holder is entitled to vote, the number of Series B Perpetual Convertible Preferred Shares equal to the number of whole Subordinate Voting Shares into which such holder’s registered Series B Perpetual Convertible Preferred Shares are convertible pursuant to these share provisions as of the record date for the determination of shareholders entitled to vote at such shareholders meeting or, if no such record date is established, the date such vote is taken or any written resolution of shareholders is solicited. The holders of Series B Perpetual Convertible Preferred Shares will be entitled to notice of all shareholders meetings or proposed actions by written consent as if such holders were holders of Subordinate Voting Shares. II. 3. Dividends. The holders of Series B Perpetual Convertible Preferred Shares shall be entitled to receive only such dividends on the Series B Perpetual Convertible Preferred Shares, if any, as are expressly declared thereon by the Board of Directors and shall not be entitled to any other dividends. The holders of Series B Perpetual Convertible Preferred Shares shall not have the right to receive any dividends that are declared only with respect to the Subordinate Voting Shares or the Multiple Voting Shares, and nothing in these Series B Perpetual Preferred Share Provisions will restrict the declaration or payment of any dividends on the Subordinate Voting Shares or the Multiple Voting Shares to the exclusion III.

From and after the date of purchase of any Series B Perpetual Convertible Preferred Shares under the provisions of this SECTION 4, any shares so purchased shall be cancelled. IV. 5. Redemption. Except as expressly set out in this SECTION 5, the Company may not redeem any of the Series B Perpetual Convertible Preferred Shares. a. (i) If a Change of Control occurs, then, the Company may elect, at its sole option, to redeem for cash all (but not less than all) of the then outstanding Series B Perpetual Convertible Preferred Shares on the date (“Redemption Date”) that is twenty (20) Business Days following the effective date of the Change of Control at a price (the “Redemption Price”) per Series B Perpetual Convertible Preferred Share equal to the greater of (i) an amount equal to (a) 105% of the Liquidation Preference as of the Redemption Date if such Change of Control occurs within five (5) years following the Original Issuance Date or (b) 100% of the Liquidation Preference as of the Redemption Date if such Change of Control occurs more than five (5) years after the Original Issuance Date; and (ii) the Fair Market Value of the consideration such holder would have received had such holder converted its Series B Perpetual Convertible Preferred Shares in accordance with SECTION 6(a) with a Conversion Date immediately prior to the effective date of the Change of Control. The Company shall provide written notice (the “Redemption Notice”) of such redemption pursuant to this SECTION 5(b)(i), on the effective date of the Change of Control to the holders of record of the Series B Perpetual Convertible Preferred Shares as they appear in the records of the Company. The Redemption Notice must state: (A) briefly, the events causing such Change of Control; (B) the effective date of such Change of Control; (C) the Redemption Price as of the Redemption Date, and the calculations supporting the specified Redemption Price; (D) the name and address of the transfer agent; (E) that the Series B Perpetual Convertible Preferred Shares may be converted at any time before the Redemption Date; and (F) the procedures a holder must follow to require the Company to convert its Series B Perpetual Convertible Preferred Shares, including the name and address of the place to where the Series B Perpetual Convertible Preferred Shares are to be surrendered for payment of the Redemption Price. The Company shall, on the Redemption Date, pay the applicable Redemption Price, upon surrender of the certificates or DRS statement representing the Series B Perpetual Convertible Preferred Shares to be redeemed. Series B Perpetual Convertible Preferred Shares to be redeemed on the Redemption Date will, from and after such date, no longer be outstanding and the rights, privileges, restrictions and conditions attaching to the Series B Perpetual Convertible Preferred Shares (except the right to receive from the Company the applicable Redemption Price) shall cease and terminate with respect to such shares; provided that in the event that a Series B Perpetual Convertible Preferred Share is not redeemed due to a default in payment by the Company, such Series B Perpetual Convertible Preferred Share will remain outstanding and will be entitled to all rights, privileges, restrictions and conditions attaching to the Series B Perpetual Convertible Preferred Shares as provided herein (including continued increases in Liquidation Preference at the applicable Accretion Rate).

(ii) In the event that the Company does not elect to redeem for cash all (but not less than all) of the then outstanding Series B Perpetual Convertible Preferred Shares on the Redemption Date pursuant to SECTION 5(b)(i), then the Accretion Rate shall automatically increase to 13% on and after the date on which such Change of Control occurs for purposes of SECTION 1(b)(iv). • (iii) For greater certainty, if a Change of Control occurs and results (or upon a completion would result) in a Change of Control, then, prior to the Redemption Date, each holder of Series B Perpetual Convertible Preferred Shares is entitled to convert, including prior to the occurrence of the Change of Control and in order to participate therein as a holder of Subordinate Voting Shares, at the option and election of such holder, any or all of the outstanding Series B Perpetual Convertible Preferred Shares held by such holder into Subordinate Voting Shares pursuant to SECTION 6(a). • Quarterly Redemption by the Company. (i) On December 31, 2025 and on each Quarterly Compounding Date thereafter (each a “Quarterly Redemption Date”), at the Company’s option and election and upon its compliance with this SECTION 5(c)(i), the Company may redeem, on a pro rata basis if there is more than one holder, such number of the then outstanding Series B Perpetual Convertible Preferred Shares having an aggregate Liquidation Preference equal to the product of: (A) one quarter (1/4) of the applicable Accretion Rate for the quarter ending on the Quarterly Redemption Date, and (B) the aggregate Liquidation Preference of all of the then outstanding Series B Perpetual Convertible Preferred Shares (rounded to the nearest whole number) as of the applicable Quarterly Redemption Date, at a price (the “Quarterly Redemption Price”) per Series B Perpetual Convertible Preferred Share equal to the Liquidation Preference as of the applicable Quarterly Redemption Date. The Quarterly Redemption Price shall be paid, at the election of the Company, in cash or, if the Liquidity Conditions are satisfied, by issuing to the holder(s) such number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares determined per Series B Perpetual Convertible Preferred Share so redeemed by dividing (i) the Quarterly Redemption Price by (ii) 97% of the Current Market Price of the Subordinate Voting Shares on the date of the applicable Quarterly Redemption Notice.

In lieu of fractional shares, the Company shall, subject to the last sentence hereof, round to the nearest whole number, the number of Subordinate Voting Shares to be issued upon payment of the applicable Quarterly Redemption Price. If more than one Series B Perpetual Convertible Preferred Share is being redeemed at one time by or for the benefit of the same holder, then the number of full Subordinate Voting Shares issuable upon such redemption will be calculated on the basis of the aggregate number of Series B Perpetual Convertible Preferred Shares redeemed by or for the benefit of such holder at such time. • Optional Redemption by the Company. (i) On and after the five (5) year anniversary of the Original Issuance Date, at the Company’s option and election and upon its compliance with this SECTION 5(d)(i), all (but not less than all) of the then outstanding Series B Perpetual Convertible Preferred Shares may be redeemed at a price (the “Optional Redemption Price”) per Series B Perpetual Convertible Preferred Share equal to (a) 105% of the Liquidation Preference as of the Optional Redemption Date if such redemption occurs prior to the six (6) year anniversary of the Original Issuance Date; (b) 103% of the Liquidation Preference as of the Optional Redemption Date if such redemption occurs after the six (6) year anniversary of the Original Issuance Date and prior to the seven (7) year anniversary of the Original Issuance Date; or (c) 100% of the Liquidation Preference as of the Optional Redemption Date if such redemption occurs after the seven (7) year anniversary of the Original Issuance Date.

Conversion at the Option of Holders of Series B Perpetual Convertible Preferred Shares. Each holder of Series B Perpetual Convertible Preferred Shares is entitled to convert, at any time and from time to time, at the option and election of such holder, any or all outstanding Series B Perpetual Convertible Preferred Shares held by such holder into a number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares equal to the number (the “Conversion Amount”) determined per each Series B Perpetual Convertible Preferred Share so converted by dividing (i) the Liquidation Preference (as adjusted pursuant to SECTION 1(b) to the applicable Conversion Date) for each Series B Perpetual Convertible Preferred Share to be converted by (ii) the Conversion Price (which Conversion Price shall be adjusted from time to time as provided in SECTION 6(e)) in effect on the Conversion Date. The “Conversion Price” is initially US$43.92, as adjusted from time to time as provided in SECTION 6(e). In order to convert the Series B Perpetual Convertible Preferred Shares into Subordinate Voting Shares pursuant to this SECTION 6(a), the holder must surrender the certificates or DRS statements representing such Series B Perpetual Convertible Preferred Shares, accompanied by transfer instruments reasonably satisfactory to the Company, at the office of the Company or its transfer agent for the Series B Perpetual Convertible Preferred Shares (as directed by the Company), together with the prescribed form of written notice, set forth on the Series B Perpetual Convertible Preferred Share certificates or DRS statement, that such holder elects to convert all or such number of shares represented by such certificates or DRS statement as specified therein. Notwithstanding the foregoing, the right of conversion may be exercised as to any portion of such holder’s Series B Perpetual Convertible Preferred Shares from time to time; provided that, in each case, no right of conversion may be exercised by a holder in respect of fewer than 27,322 Series B Perpetual Convertible Preferred Shares (unless such conversion is in respect of all Series B Perpetual Convertible Preferred Shares held by such holder). a. Conversion at the Option of the Company. (i) If the Liquidity Conditions are satisfied, on and after the three (3) year anniversary of the Original Issuance Date, at the Company’s option and election and upon its compliance with this SECTION 6(b)(i), all (but not less than all) outstanding Series B Perpetual Convertible Preferred Shares shall be converted into a number of duly authorized, validly issued, fully paid and non-assessable Subordinate Voting Shares equal to the then-applicable Conversion Amount per each Series B Perpetual Convertible Preferred Share so converted, upon written notice by the Company to holders of record of the Series B Perpetual Convertible Preferred Shares as they appear in the records of the Company notifying such holders of the conversion contemplated by this SECTION 6(b)(i), which conversion shall occur on the tenth (10th) Business Day following the date of such notice, which Conversion Date shall be specified in such notice, provided, that such notice may be delivered by the Company (and such Series B Perpetual Convertible Preferred Shares may be converted into Subordinate Voting Shares pursuant to this SECTION 6(b)(i)) only if the Closing Price (or, if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount • b.

No fractional Subordinate Voting Shares will be issued upon conversion of the Series B Perpetual Convertible Preferred Shares. In lieu of fractional shares the Company shall, subject to the last sentence hereof, round to the next whole number, the number of Subordinate Voting Shares to be issued upon conversion of the Series B Perpetual Convertible Preferred Shares. If more than one Series B Perpetual Convertible Preferred Share is being converted at one time by or for the benefit of the same holder, then the number of full Subordinate Voting Shares issuable upon conversion will be calculated on the basis of the aggregate number of Series B Perpetual Convertible Preferred Shares converted by or for the benefit of such holder at such time, and if all of the Series B Perpetual Convertible Preferred Shares held by a holder are being converted at the same time, then the number of full Subordinate Voting Shares issuable upon conversion will be calculated on the basis of the aggregate number of Series B Perpetual Convertible Preferred Shares converted by or for the benefit of such holder at such time, with any resulting fractional entitlement being rounded to the nearest whole number. c. Mechanics of Conversion. (i) On the second Business Day immediately succeeding the Conversion Date, the Company shall issue and deliver to each holder of Series B Perpetual Convertible Preferred Shares the number of Subordinate Voting Shares to which such holder is entitled in exchange for the certificates or DRS statement formerly representing Series B Perpetual Convertible Preferred Shares. Such conversion will be deemed to have been made on the Conversion Date, and the person entitled to receive the Subordinate Voting Shares issuable upon such conversion shall be treated for all purposes as the record holder of such Subordinate Voting Shares on such Conversion Date.

without cost to the holder thereof, except for any documentary, stamp or similar issue or transfer tax due because any certificates DRS statement for Subordinate Voting Shares or Series B Perpetual Convertible Preferred Shares are registered in a name other than the name of the converting holder. The Company shall pay any documentary, stamp or similar issue or transfer tax due on the issue of Subordinate Voting Shares upon conversion or due upon the issuance of a new certificate or DRS statement for any Series B Perpetual Convertible Preferred Shares not converted other than any such tax due because Subordinate Voting Shares or a certificate DRS statement for Series B Perpetual Convertible Preferred Shares are issued in a name other than the name of the converting holder, which shall be paid by the converting holder. (ii) From and after the Conversion Date, the Series B Perpetual Convertible Preferred Shares to be converted on such Conversion Date will no longer be outstanding, and all rights and privileges of the holder thereof as a holder of Series B Perpetual Convertible Preferred Shares (except the right to receive from the Company the Subordinate Voting Shares upon conversion) shall cease and terminate with respect to such shares. • (iii) All Subordinate Voting Shares issued upon conversion of the Series B Perpetual Convertible Preferred Shares will, upon issuance by the Company, be duly and validly issued, as fully paid and non-assessable Subordinate Voting Shares in the capital of the Company. • Adjustments to Conversion Price. (i) Adjustments for issuances of subordinate voting shares, share splits and share combinations. If the Company shall, at any time and from time to time while any Series B Perpetual Convertible Preferred Shares are outstanding, issue Subordinate Voting Shares as a dividend or distribution to all or substantially all holders of its Subordinate Voting Shares or the Company shall effect a share split or share combination of Subordinate Voting Shares into a greater or lesser number of Subordinate Voting Shares (in each case excluding an issuance solely pursuant to a Capital Reorganization, as to which SECTION 6(e)(vi) will apply), then the then-applicable Conversion Price will be adjusted in accordance with the following formula: • e. where CP0 = the Conversion Price in effect immediately prior to the close of business on the Record Date for such dividend or distribution or immediately prior to the open of business on the Effective Date for such share split or share combination, as the case may be; CP1 = the Conversion Price in effect immediately after the close of business on such Record Date or immediately after the open of business on such Effective Date, as the case may be; OS0 = the number of Subordinate Voting Shares outstanding immediately prior to the close of business on such Record Date or immediately prior to the open of business on such Effective Date, as the case may be (in either case, prior to giving effect to such event); and OS1 = the number of Subordinate Voting Shares that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split or share combination. Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(i) shall become effective immediately after the close of business on the Record Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

as the case may be. If any dividend or distribution of the type described in this SECTION 6(e)(i) is declared but not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to make such dividend or distribution, to such Conversion Price that would be in effect if such dividend or distribution had not been declared. For the purposes of this SECTION 6(e)(i), the number of Subordinate Voting Shares outstanding immediately prior to the close of business on the Record Date for such dividend or distribution or the open of business on the Effective Date for such share split or share combination, as applicable, shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of Subordinate Voting Shares. The Company shall not pay any such dividend or make any such distribution on Subordinate Voting Shares held in treasury by the Company. (ii) Adjustments for certain rights, options and warrants. If the Company shall, at any time or from time to time, while any Series B Perpetual Convertible Preferred Shares are outstanding, issue to all or substantially all holders of Subordinate Voting Shares rights, options or warrants (other than rights issued pursuant to a shareholder rights plan, as to which SECTION 6(e)(iv)(B) and SECTION 6(e)(xii) will apply) entitling such holders, for a period of up to 45 calendar days from the date of issuance of such rights, options or warrants, to subscribe for or purchase Subordinate Voting Shares at a price per share less than the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, then the then-applicable Conversion Price shall be adjusted based on the following formula: ○ CP1=CP0 x (OS0+Y)(OS0+X) where, CP0 = the Conversion Price in effect immediately prior to the opening of business on the Record Date for such issuance; CP1 = the Conversion Price in effect immediately after the close of business on such Record Date; OS0 = the number of Subordinate Voting Shares outstanding immediately prior to the close of business on such Record Date; X = the total number of Subordinate Voting Shares issuable pursuant to such rights, options or warrants; and Y = the total number of Subordinate Voting Shares equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance. Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(ii) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the close of business on the Record Date for such issuance. In the event that such rights, options or warrants described in this clause (ii) are not so issued, the Conversion Price BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to issue such rights, options or warrants, to such Conversion Price that would then be in effect if such issuance had not been declared. To the extent that such rights, options or warrants are not exercised prior to their expiration or Subordinate Voting Shares are otherwise not delivered pursuant to such rights, options or warrants upon the exercise of such rights, options or warrants, the Conversion Price shall be readjusted, effective as of the date of such expiration or the date it is determined such shares will not be delivered, as the case may be, to such Conversion Price that would then be in effect had the adjustment made upon the issuance of such rights, options or warrants been made on the basis of the delivery of only the number of Subordinate Voting Shares actually delivered. In determining whether any rights, options or warrants entitle the holders thereof to subscribe for or purchase Subordinate Voting Shares at less than the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, and in determining the aggregate price payable to exercise such rights, options or warrants, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors. For the purposes of this SECTION 6(e)(ii), the number of Subordinate Voting Shares at the time outstanding shall not include shares held in treasury by the Company but shall include any shares issuable in respect of any scrip certificates issued in lieu of fractions of Subordinate Voting Shares. The Company shall not issue any such rights, options or warrants in respect of Subordinate Voting Shares held in treasury by the Company. (iii) Adjustments for Payment of Cash Dividends. If the Company makes a dividend or distribution consisting exclusively of cash to all or substantially all holders of Subordinate Voting Shares (excluding (1) any regular quarterly dividend that does not exceed US$0.011 per Subordinate Voting Share (“Dividend Threshold Amount”), (2) any cash that is distributed in, and will constitute Reference Property as a result of, a Capital Reorganization in exchange for Subordinate Voting Shares and (3) any dividend or distribution in connection with the liquidation, dissolution or winding up of the Company), then the Conversion Price shall be adjusted based on the following formula: ○ CP1=CP0 x (SP0-C)(SP0-T) where, CP0 = the Conversion Price in effect immediately prior to the close of business on the Record Date for such dividend or distribution; CP1 = the Conversion Price in effect immediately after the close of business on the Record Date for such dividend or distribution; SP0 = the average of the Closing Prices per Subordinate Voting Share (if the Closing Price on any Trading Day is quoted only in Canadian dollars, the USD Equivalent Amount thereof on such Trading Day) over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such dividend or distribution; T = the Dividend Threshold Amount; provided that if the dividend or distribution is not a regular quarterly cash dividend, the Dividend Threshold Amount shall be deemed to be zero; and BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

C = the amount in cash per share the Company distributes to holders of Subordinate Voting Shares. The Dividend Threshold Amount is subject to adjustment in the same manner as, and at the same time and for the same events for which, the Conversion Price is adjusted, but no adjustment shall be made to the Dividend Threshold Amount for any adjustment made to the Conversion Price pursuant to this SECTION 6(e)(iii). Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(iii) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. If any dividend or distribution of the type described in this SECTION 6(e)(iii) is declared but not so paid or made, the Conversion Price shall again be adjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution, to the Conversion Price which would then be in effect if such dividend or distribution had not been declared. Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing decrease, each holder of Series B Perpetual Convertible Preferred Shares shall receive at the same time and upon the same terms as holders of Subordinate Voting Shares, the amount of cash as a dividend on the Series B Perpetual Convertible Preferred Shares that such holder would have received if such holder owned a number of Subordinate Voting Shares at the Conversion Price in effect immediately prior to the close of business on the Record Date for such cash dividend or distribution. ○ (iv) Adjustments for certain distributions. (A) If the Company shall, at any time and from time to time while any Series B Perpetual Convertible Preferred Shares are outstanding, distribute to all or substantially all holders of the Subordinate Voting Shares any shares of Capital Stock (other than Subordinate Voting Shares), evidences of the Company’s indebtedness, assets or rights, options or warrants to acquire Capital Stock, indebtedness or assets (excluding (1) any dividend or distribution (including share splits or share combinations) as to which an adjustment was effected pursuant to SECTION 6(e)(i), (2) any rights, options or warrants as to which an adjustment was effected pursuant to Section 6(e)(ii), (3) except as otherwise described in SECTION 6(e)(xiii), rights issued pursuant to any shareholder rights plan of the Company then in effect, (4) any dividend or distribution described in SECTION 6(e)(iii), (5) distributions of Reference Property in a transaction described in SECTION 6(e)(vi) and (6) any Spin-Off to which the provisions set forth in SECTION 6(e)(iv)(B) shall apply, then the applicable Conversion Price will be adjusted based on the following formula: CP1=CP0 x (SP0-FMV)SP0 where, CP0 = the Conversion Price in effect immediately prior to the close of business on the Record Date for such dividend or distribution; CP1 = the Conversion Price in effect immediately after the close of business on such Record Date; SP0 = the average of the Closing Prices per Subordinate Voting Share for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the Ex-Date for such dividend or distribution; and BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

FMV = the Fair Market Value on such Record Date of the shares, evidences of indebtedness, assets or rights, options or warrants so distributed, expressed as an amount per Subordinate Voting Share. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP0” (as defined above), in lieu of the foregoing decrease, each holder of Series B Perpetual Convertible Preferred Shares shall receive at the same time and upon the same terms as holders of Subordinate Voting Shares, the kind and amount of the Company’s shares, evidences of indebtedness, assets or rights, options or warrants that such holder would have received if such holder owned a number of Subordinate Voting Shares at the Conversion Price in effect immediately prior to the close of business on the Record Date for such dividend or distribution. Any adjustment to the Conversion Price made pursuant to this SECTION 6(e)(iv)(A) shall become effective immediately after the close of business on the Record Date for such dividend or distribution. In the event that such distribution described in this SECTION 6(e)(iv)(A) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such distribution, to the Conversion Price that would then be in effect if such dividend or distribution had not been announced. (B) In a Spin-Off, the Conversion Price will be adjusted based on the following formula: CP1=CP0 x MP0(FMV0+MP0) where, CP0 = the Conversion Price in effect immediately prior to the open of business on the Ex-Date for the Spin-Off; CP1 = the Conversion Price in effect immediately after the open of business on the Ex-Date for the Spin-Off; FMV0 = the average of the Closing Prices (as if references to “Subordinate Voting Shares” therein were references to such shares or similar equity interest distributed to holders of Subordinate Voting Shares) of the shares or similar equity interests so distributed applicable to one Subordinate Voting Share for the 10 consecutive Trading Day period commencing on, and including, the Ex-Date for the Spin-Off (the “Valuation Period”); and MP0 = the average of the Closing Prices per Subordinate Voting Share for the Valuation Period. Any adjustment made pursuant to this clause (vi)(B) will be calculated immediately after the close of business on the last Trading Day of the Valuation Period but shall be given effect as of immediately after the open of business on the Ex-Date for the Spin-Off; provided that, if any Conversion Date occurs during the Valuation Period, the Company shall, to the extent necessary, delay any settlement of such conversion until the second Business Day after the last day of the Valuation Period. In the event that such distribution described in this clause (vi)(B) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such distribution, to the Conversion Price that would then be in effect if such distribution had not been announced. The Company shall not make any such dividend or distribution on Subordinate Voting Shares held in treasury by the Company. (v) Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries successfully completes a tender offer or exchange offer for Subordinate Voting Shares (other than a normal course issuer bid under applicable Canadian securities laws) where the cash and the value of any other consideration included in the payment per Subordinate Voting Share validly tendered or exchanged exceeds the average of the ○ BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

Closing Prices per Subordinate Voting Share for the 10 consecutive Trading Day period (the “Averaging Period”) commencing on, and including, the Trading Day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender offer or exchange offer (the “Tender Offer Expiration Date”), then the Conversion Price will be adjusted based on the following formula: CP1=CP0 x (SP0 x OS0)AC+(SP0 x OS1) where, CP0 = the Conversion Price in effect immediately prior to the close of business on the Tender Offer Expiration Date; CP1 = the Conversion Price in effect immediately after the close of business on the Tender Offer Expiration Date; SP0 = the average of the Closing Prices per Subordinate Voting Share over the Averaging Period; OS0 = the number of Subordinate Voting Shares outstanding immediately prior to the Tender Offer Expiration Date, prior to giving effect to the purchase of any shares accepted for purchase or exchange in such tender offer or exchange offer; AC = the aggregate value of all cash and the Fair Market Value (as determined by the Board of Directors) on the Tender Offer Expiration Date of any other consideration paid or payable for Subordinate Voting Shares acquired pursuant to such tender offer or exchange offer; and OS1 = the number of Subordinate Voting Shares outstanding immediately after the Tender Offer Expiration Date, after giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer. The Conversion Price will in no event be adjusted up pursuant to this SECTION 6(e)(v), except to the extent provided in the last sentence of this paragraph. Any adjustment to the Conversion Price pursuant to this SECTION 6(e)(v) will be calculated as of the close of business on the last Trading Day of the Averaging Period, but shall be given effect immediately after the close of business on the Tender Offer Expiration Date; provided that, if any Conversion Date occurs during the Averaging Period, the Company shall, if necessary, delay any settlement of such conversion until the second Business Day after the last day of the Averaging Period. If the Company or one of its Subsidiaries is obligated to purchase Subordinate Voting Shares pursuant to any such tender or exchange offer, but the Company or such Subsidiary is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Price shall be readjusted to be such Conversion Price that would then be in effect if such tender or exchange offer had not been made. (vi) Capital Reorganization Events. In the case of: any consolidation, amalgamation or merger of the Company with or into another Person (other than a merger, amalgamation or consolidation in which the Company is the continuing or surviving corporation and in which the Subordinate Voting Shares outstanding immediately prior to the merger, amalgamation or consolidation are not exchanged for cash, securities or other property of the Company or another Person); A. ○ BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

any direct or indirect sale, lease, assignment, transfer or conveyance of all or substantially all of the Company’s consolidated property or assets; B. any reclassification of Subordinate Voting Shares into securities, including securities other than the Subordinate Voting Shares (other than changes in par value, if any, or resulting from a subdivision or combination); or C. any statutory exchange of securities of the Company with another Person (other than in connection with a merger or acquisition); D. in each case, as a result of which the Subordinate Voting Shares would be converted into, or exchanged for, securities, cash or other property (each, a “Capital Reorganization”), then, at and after the effective time of such Capital Reorganization, the right to exchange each Series B Perpetual Convertible Preferred Share shall be changed into a right to exchange such share into the kind and amount of shares, cash, other securities or other property or assets (or any combination thereof) that a holder of a number of Subordinate Voting Shares equal to the Conversion Amount (with respect to such Series B Perpetual Convertible Preferred Share) immediately prior to such Capital Reorganization would have owned or been entitled to receive upon such Capital Reorganization (such shares, securities or other property or assets, the “Reference Property”, with each unit of Reference Property being the kind and amount of Reference Property that a holder of one Subordinate Voting Share would have received in such Capital Reorganization). Prior to or at the effective time of such Capital Reorganization, the Company or the successor or purchasing person, as the case may be, shall execute and deliver such supplemental instruments, if any, as the Company reasonably determines are necessary or desirable to (1) provide for subsequent adjustments to the Conversion Price pursuant to SECTION 6(e) in a manner consistent with this SECTION 6(e)(vi) (including giving effect, in the Company’s reasonable discretion, to the Dividend Threshold Amount in a manner that preserves the economic interests of the holders); and (2) give effect to such other provisions, if any, as the Company reasonably determines are appropriate to preserve the economic interests of the holders. If the Reference Property includes shares of stock or other securities or assets of a person other than such successor person, then such other person will also execute such supplemental instrument(s) and such supplemental instrument(s) will contain such additional provisions, if any, that the Company reasonably determines are appropriate to preserve the economic interests of holders. In each case, if a Capital Reorganization causes the Subordinate Voting Shares to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), then the Reference Property into which the Series B Perpetual Convertible Preferred Shares will be exchangeable shall be deemed to be the weighted average of the types and amounts of consideration received by the holders of Subordinate Voting Shares. The Company shall notify the holders of the Series B Perpetual Convertible Preferred Shares of such weighted average as soon as practicable after such determination is made. For these purposes, the Closing Price of any unit of Reference Property or portion thereof that does not consist of a class of securities will be the fair value of such unit of Reference Property Unit or portion thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face amount thereof). None of the foregoing provisions shall affect (x) the right of a holder of Series B Perpetual Convertible Preferred Shares to convert its Series B Perpetual Convertible Preferred Shares (1) into Subordinate Voting Shares prior to the effective time of such Capital Reorganization or (2) into Subordinate Voting Shares or Reference Property, as applicable, following the effective time of such Capital Reorganization, in any case pursuant to SECTION 6(a), or, (y) if the event constituting a Capital Reorganization is also a Change of Control, the obligation of the Company to redeem the Series B Perpetual Convertible Preferred Shares in connection with such transaction pursuant to SECTION 5. The provisions of this SECTION 6(e)(vi) shall similarly apply to successive Capital Reorganization events. This SECTION 6(e)(vi) shall not apply to any share split or combination to which SECTION 6(e)(i) is applicable or to a Liquidation Event. ○ (vii) The Company shall not enter into any agreement for a transaction constituting a Capital BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

Reorganization unless its terms are consistent with SECTION 6(e)(vi). (viii) Minimum Adjustment. Notwithstanding the foregoing, the Conversion Price will not be reduced if the amount of such reduction would be an amount less than US$0.01, but any such amount will be carried forward and reduction with respect thereto will be made (1) at the time that such amount, together with any subsequent amounts so carried forward, aggregates to US$0.01 or more; (2) upon the Conversion Date of any Series B Perpetual Convertible Preferred Share; (3) upon the date a Change of Control occurs; and (4) upon the date the Company sends any notice of redemption pursuant to SECTION 5. ○ (ix) When No Adjustment Required. Notwithstanding anything herein to the contrary, no adjustment to the Conversion Price need be made: upon the issuance of any Subordinate Voting Shares pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Company’s securities and the investment of additional optional amounts in Subordinate Voting Shares under any plan; A. upon the repurchase of any Subordinate Voting Shares pursuant to the trust or escrow arrangement entered into on behalf of the legacy option holders before the Original Issuance Date; B. upon the issuance of any Subordinate Voting Shares in accordance with the terms of the Company’s Multiple Voting Shares; C. upon the issuance of any Subordinate Voting Shares or rights, options, restricted share units, warrants or similar securities to purchase those shares pursuant to any present or future employee, director or consultant benefit or incentive plan or program of or assumed by the Company or any of its Subsidiaries; D. upon the repurchase of any Subordinate Voting Shares pursuant to an open market share repurchase program or other buy-back transaction, including structured or derivative transactions, that is not a tender offer or exchange offer of the nature described in SECTION 6(e)(v); E. for the sale or issuance of Subordinate Voting Shares, or securities convertible into or exercisable for Subordinate Voting Shares, for cash, including at a price per share less than the Fair Market Value thereof or otherwise or in an acquisition, except as described in one of SECTION 6(e)(i) through SECTION 6(e)(v) above; F. G. for a third-party tender offer; upon the issuance of any Subordinate Voting Shares pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the Original Issuance Date; or H. for any other issuance of Subordinate Voting Shares or any securities convertible into or exchangeable for Subordinate Voting Shares or the right to purchase Subordinate Voting Shares or such convertible or exchangeable securities, except as described above or below. A. ○ (x) Rules of Calculation. All calculations will be made to the nearest one-hundredth of a cent or to the nearest one-ten thousandth of a share. Except as explicitly provided herein, the number of Subordinate Voting Shares outstanding will be calculated on the basis of the number of issued and outstanding ○ BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.

Subordinate Voting Shares. (xi) Waiver. Notwithstanding anything in this SECTION 6(e) to the contrary, no adjustment need be made to the Conversion Price for any event with respect to which an adjustment would otherwise be required pursuant to this SECTION 6(e) if the Company receives, prior to the effective time of the adjustment to the Conversion Price, written notice from the holders representing at least a majority of the then outstanding Series B Perpetual Convertible Preferred Shares that no adjustment is to be made as the result of a particular issuance of Subordinate Voting Shares or other dividend or other distribution on Subordinate Voting Shares. This waiver will be limited in scope and will not be valid for any issuance of Subordinate Voting Shares or other dividend or other distribution on Subordinate Voting Shares or any other event not specifically provided for in such notice. ○ (xii) Shareholder Rights Plans. To the extent that the Company has a rights plan in effect with respect to the Subordinate Voting Shares on any Conversion Date, Holders shall receive, in addition to the Subordinate Voting Shares, the rights under the rights plan, unless, prior to such Conversion Date, the rights have separated from the Subordinate Voting Shares, in which case the Conversion Price shall be adjusted at the time of separation as if the Company made a distribution to all holders of the Subordinate Voting Shares as described in SECTION 6(e)(iv)(A), subject to readjustment in the event of the expiration, termination or redemption of such rights. ○ (xiii) Reservation of Shares. For the purpose of effecting the conversion of Series B Perpetual Convertible Preferred Shares, the Company shall at all times reserve and keep available, free from any preemptive rights, out of its treasury or authorized but unissued Subordinate Voting Shares the full number of Subordinate Voting Shares deliverable upon the conversion of all outstanding Series B Perpetual Convertible Preferred Shares after taking into account any adjustments to the Conversion Price from time to time pursuant to the terms of this SECTION 6 and any increases to the Liquidation Preference from time to time and assuming for the purposes of this calculation that all outstanding Series B Perpetual Convertible Preferred Shares are held by one holder. All Subordinate Voting Shares delivered upon conversion of Series B Perpetual Convertible Preferred Shares shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests and other encumbrances (other than liens, charges, security interests and other encumbrances created by the holders) and free of preemptive rights. If the Subordinate Voting Shares are then listed on any securities exchange, or quoted on any inter-dealer quotation system, then the Company will cause each such Subordinate Voting Share, when so delivered, to be admitted for listing on such exchange or quotation on such system. ○ (xiv) Successive Adjustments. For the avoidance of doubt, after an adjustment to the Conversion Price under this SECTION 6, any subsequent event requiring an adjustment under this SECTION 6 shall cause an adjustment to such Conversion Price as so adjusted. ○ Certificate of Adjustments. Promptly upon the occurrence of any event requiring an adjustment or readjustment of the Conversion Price pursuant to this SECTION 6, the Company shall compute such adjustment or readjustment in accordance with the terms hereof and, within five (5) Business Days of such event, provide to each holder of Series B Perpetual Convertible Preferred Shares a notice setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based, including a brief description of the transaction or other event and the effective time of such adjustment. The Company shall, upon the reasonable written request of any holder of Series B Perpetual Convertible Preferred Shares, furnish to such holder (i) the calculation of such adjustments and readjustments in reasonable detail, (ii) the Conversion Price then in effect, and (iii) the number of Subordinate Voting Shares and the amount, if any, of share capital, other • BCA - Articles of Amalgamation - GFL ENVIRONMENTAL INC. - OCN:1000750064 - January 01, 2024 The endorsed Articles of Amalgamation are not complete without the Certificate of Amalgamation.
