The Canadian Sustainability Standards Board (CSSB) is an independent body dedicated to enhancing sustainability reporting in Canada. It operates under the oversight of the Canadian Auditing and Assurance Standards Board (AASB) and the Accounting Standards Board (AcSB). The CSSB develops high-quality sustainability disclosure standards that align with global frameworks.

The primary output of the CSSB is the Canadian Sustainability Disclosure Standards (CSDS), which include CSDS 1, focusing on general requirements for disclosing sustainability-related financial information, and CSDS 2, which outlines specific requirements for climate-related disclosures. These standards are voluntary and aim to harmonize with international benchmarks, ensuring compatibility with global reporting practices. The CSSB’s work supports Canadian companies, particularly publicly traded entities, by promoting transparency in sustainability reporting and influencing regulatory frameworks. The standards will apply to annual reporting periods starting January 1, 2025, with phased implementation guidance for the first three years.
