Indigenous Matters in the Canadian Standard on Sustainability Assurance (CSSA) 5000, General Requirements for Sustainability Assurance Engagements

Summary

The Auditing and Assurance Standards Board (AASB) has adopted the International Standard on Sustainability Assurance (ISSA) 5000, General Requirements for Sustainability Assurance Engagements, as a new Canadian Standard on Sustainability Assurance (CSSA) 5000.

Background

Sustainability information is highly relevant and has a significant impact on Indigenous Peoples. The Government of Canada has accepted the Truth and Reconciliation Commission (TRC) Report, including the 94 Calls to Action. The TRC’s Call to Action 92 highlights the necessity of incorporating Indigenous rights into corporate policies and operations.

The AASB recognizes that:

  • practitioners may struggle to determine how Indigenous rights are incorporated into an entity’s policies and operations, especially when sustainability reporting criteria do not address diverse interests; and
  • offering further guidance to practitioners serves the public interest by strengthening the integrity and reliability of sustainability assurance engagements.

The AASB has proposed a Canadian amendment related to Indigenous matters in CSSA 5000, General Requirements for Sustainability Assurance Engagements, requiring practitioners to obtain an understanding of the entity’s response to TRC’s Call to Action 92 to identify and assess risks of material misstatement that may be pervasive throughout the sustainability information related to that response.

By incorporating this amendment into CSSA 5000, the AASB believes that Canadian practitioners will be better equipped to provide sustainability assurance reporting that considers Indigenous rights and promotes ethical corporate practices.

AASB Decision Summary December 1-2 2025

The AASB discussed the proposed Canadian Standard on Sustainability Assurance (CSSA) 5000, General Requirements for Sustainability Assurance Engagements, and the amendment related to Indigenous matters in CSSA 5000. Key issues discussed included:

  • the volume of comments received on the Re-Exposure Draft of the amendment related to Indigenous matters, suggesting there are unresolved implementation challenges and a need for additional subject-matter expertise to support the project moving forward;
  • agreement that, based on feedback received on the Indigenous amendment:
    • the Board, with support from its Sustainability Assurance Committee, will require additional time, beyond what was anticipated at re-exposure, to carefully analyze and respond to all feedback;
    • further field testing on the revised Indigenous amendment is necessary to ensure that implementation challenges are resolved; and
    • interested parties need to be updated on the status and next steps for the Indigenous amendment, including the anticipated timeline for completion.
  • whether to finalize CSSA 5000 while continuing to work on the Indigenous amendment, in order to maintain congruence with the international standard and reduce market confusion.

The AASB will continue discussing the Indigenous amendment at its January 2026 meeting.
