Exposure Draft

Audits of Less Complex Entities

The AASB established the Audits of Less Complex Entities Working Group

Canadian Activities to Inform the International Auditing and Assurance Standards Board’s (IAASB) International Standard on Auditing (ISA) 540 (Revised) Post-implementation Review

IAASB is discussing the feedback received on their public consultation survey to develop recommendations for the way forward

Listed Entity and Public Interest Entity

Track 1

The IAASB approved narrow-scope amendments to ISA 700 (revised) and ISA 260 (revised)

The AASB approved narrow-scope amendments to CAS 700 and CAS 260

Track 2

The IAASB approved narrow-scope amendments to the ISQMs, ISAs, and ISRE 2400 (Revised) as a result of the revisions to the definitions of “listed entity” and “public interest entity” in the IESBA Code

The AASB decided to continue to defer adoption of the IAASB’s narrow-scope amendments

The AASB approved Canadian amendments to CSQMs and CASs, which will be issued in the CPA Canada Handbook in July 2026. As the AASB did not adopt the IAASB’s narrow-scope amendments, there are no changes to the effective dates of requirements in CSQMs and CASs

Targeted Standards in the Canadian Auditing Standards (CAS) 500 Series

The IAASB approved the project proposal for the ISA 500 Series in March 2026.
