August 2019


On March 21, 2017, the Canadian Securities Administrators (CSA) announced a project to review the disclosure of risks and financial impacts associated with climate change. The project will gather information on the current state of climate change disclosure in Canada and internationally, and will include consultation with investors and reporting issuers.

Reporting issuers in Canada are currently required to disclose material risks, which may include risks associated with climate change, among other environmental matters, in their periodic disclosure. The existing CSA guidance with respect to climate change disclosure is contained in CSA Staff Notice, 51-333, Environmental Reporting Guidance, dated October 27, 2010. 

CSA Staff intend to review disclosure prepared by large TSX-listed reporting issuers on the material risks and financial impacts associated with climate change as well as related governance processes.

Following this review, on Au­gust 1, 2019, the CSA issued CSA Staff No­tice 51-358 Re­port­ing of Cli­mate Change-re­lated Risks, which is in­tended to as­sist com­pa­nies in iden­ti­fy­ing and im­prov­ing their dis­clo­sure of ma­te­r­ial risks posed by cli­mate change. Notice 51-358 does not create any new legal requirements or modify existing ones. It reinforces and expands upon the guidance provided in CSA Staff Notice 51-333 and should be read in conjunction with CSA Staff Notice 51-333, which continues to provide guidance to issuers on existing continuous disclosure requirements relating to a broad range of environmental matters, including climate change.
