The text of the Regulatory Amendments and General Instruction Amendments is published with this notice and can be viewed on the websites of the CSA member jurisdictions, including: • www.bcsc.bc.ca • www.asc.ca • www.mbsecurities.ca • www.fcaa.gov.sk.ca • www.osc.ca • www.lautorite.qc.ca • nssc.novascotia.ca • www.fcnb.ca

Purpose The Regulatory Amendments and General Instruction Amendments aim to address the following: • the creation by the Canadian Securities Exchange (the "CSE"), through amendments to its listing policies, of a Senior Tier (the "CSE Senior Tier") for the listing of non-emerging issuers, which is currently classified as an emerging issuer tier in securities legislation; • the objective of ensuring that issuers on the CSE Senior Tier are treated identically under securities legislation to issuers listed on another non-emerging exchange; • the change of name of the PLUS Markets, which have become AQSE Growth Market following their sale by PLUS Markets Group plc; • the change of name of La Neo Bourse Aequitas Inc. to Cboe Canada Inc. due to its acquisition by Cboe Global; • the amendments made to the Canada Business Corporations Act (the "CBCA") regarding "majority voting," which may have created uncertainty regarding the voting choices that must be offered to security holders in an uncontested election of directors for issuers incorporated under the CBCA and those provided for in securities legislation.

Background The CSE's listing policy amendments establishing the CSE Senior Tier came into force on April 3, 2023. This tier was created for non-emerging issuers, and its initial and continuous listing conditions align with those of non-emerging exchanges. However, the CSE is an emerging exchange within the meaning of "emerging issuer" in securities legislation.

On January 15, 2019, La Neo Bourse Aequitas Inc. became NEO Exchange Inc., and then, on June 1, 2022, Cboe Canada Holdings, ULC acquired the direct shareholder of this exchange. Since January 1, 2024, the latter has been merged with other related entities to form a single legal entity named Cboe Canada Inc.

The PLUS Markets have become AQSE Growth Market, operated by Aquis Stock Exchange Limited.

Furthermore, August 31, 2022, marks the coming into force of amendments affecting the CBCA and the Canada Business Corporations Regulations, 2001 (the "majority voting amendments") which generally require that, in an uncontested election of directors for an issuer incorporated under the CBCA, each candidate for the position of director be elected by a "majority of votes" cast. When the majority voting amendments apply, the proxy form must allow security holders to specify, for each candidate for the position of director, the direction in which the voting right should be exercised, whereas under subsection 6 of section 9.4 of NI 51-102, it must allow specifying whether the proxyholder should exercise or abstain from exercising the voting right attached to the securities.

To dispel any uncertainty regarding the voting choices that must be offered to security holders of issuers incorporated under the CBCA subject to the majority voting amendments and those provided for in subsection 6 of section 9.4 of NI 51-102, the jurisdictions represented within the CSA issued harmonized local decisions on January 31, 2023, which exempt issuers incorporated under the CBCA from the proxy form requirement related to the election of directors provided for in the aforementioned subsection in the context of an uncontested election of directors[1].

In some jurisdictions represented within the CSA, the local decision will expire or be revoked when the related amendments to NI 51-102 come into force. The Ontario local decision will expire on January 31, 2026.
