About the AASB

The Auditing and Assurance Standards Board (AASB) establishes standards for assurance and related services engagements. The AASB contributes to the development of International Standards on Auditing (ISAs), which it adopts as Canadian Auditing Standards (CASs), by participating in consultations and activities of the International Auditing and Assurance Standards Board (IAASB) to ensure Canadian entities’ auditing needs are considered.

The Auditing and Assurance Standards Oversight Council (AASOC) oversees the activities of the AASB and ensures it follows its rigorous due process. AASOC appoints AASB members and provides input on strategy and priorities. AASOC also assesses and reports to the public on the performance of the AASB.

Auditing and Assurance Standards Board

Why the AASB Matters

The general public and stakeholders in the Canadian economy need reliable information to make financial decisions. The AASB’s strong and clear auditing, assurance and related services standards raise the credibility of public accountants.

The AASB’s History

1973: The Canadian Institute of Chartered Accountants (CICA)* established the Auditing Standards Committee, which was made up of volunteer members who were directly responsible for the development of new standards.

1991: The Auditing Standards Committee was renamed as the Auditing Standards Board, signifying a structural change to the auditing standard-setting process in Canada. The new Board began to operate in accordance with the present AASB philosophy, whereby the Board approves matters of principle and policy while the development of new standards is delegated to staff.

1998: The Auditing Standards Board was again renamed as the Assurance Standards Board, assuming responsibility for setting standards and practice guidance for assurance and related services for public sector entities. This had previously been the responsibility of the Public Sector Accounting and Auditing Board.

2003: The Assurance Standards Board was renamed the Auditing and Assurance Standards Board (AASB) as it is known today.

The AASB’s Relationship with CPA Canada


CPA Canada is the national organization representing the Chartered Professional Accountants (CPA) profession in Canada. CPA Canada provides funding, staff and other resources to support an independent standard-setting process.

CPA Canada and the boards and oversight councils function at arm’s length from one another. As a result, the boards and oversight councils, as well as their staff, carry out their standard-setting operations in an independent manner.


* The CICA, CGA-Canada and CMA Canada have since consolidated under the CPA Canada banner as the profession’s national body.
