The Auditing and Assurance Standards Board (AASB) is an independent body with the authority and responsibility to set standards for quality control, audit, other assurance and related services engagement and guidance in Canada.

We contribute to the development of International Standards on Auditing (ISAs), which we adopt 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 AASB at work.

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

The Auditing and Assurance Standards Oversight Council (AASOC) oversees our activities and ensures we follow our rigorous due process with due regard for the public interest. AASOC appoints our members and provides input on strategy and priorities. AASOC also assesses and reports to the public on our performance.


We serve a number of stakeholders, including:

  • members of the public;
  • public accountants;
  • financial statement preparers;
  • investors, creditors, analysts and bond raters;
  • boards and audit committees;
  • governments; and
  • regulators.


14 members make up the AASB. View current AASB members.

Our membership consists of a diverse group of members with a range of experience from various locations across Canada.   

The Board’s support staff includes:

  • a Director;
  • seven principals; and
  • one administrative assistant.

The Board also hires consultants as the need arises.


We normally meet five times a year. Additional meetings and conference calls may take place.
