TSX Amendments to Original Listing Requirements

TSX continuously seeks opportunities to improve the quality and integrity of the marketplace. With that aim in mind, TSX has introduced new original listing requirements (“OLRs”) for corporate issuers seeking to list on TSX. These OLRs seek to ensure that our rules: (i) continue to reflect the current needs and expectations of Canadian and global capital market participants; (ii) provide clear and pragmatic listing requirements; and (iii) reduce the need for discretionary waivers and exemptions, thereby reducing issuer burden, while maintaining sound requirements to protect marketplace quality.
