Raison d’être, mandate, and role: Who we are and what we do

Raison d’être

The Office of the Auditor General of Canada (OAG) is the legislative audit office of the federal government and of the 3 northern territories. The main legislative auditing duties are financial audits, performance audits, special examinations, and sustainable development monitoring activities and environmental petitions. Our audits and studies provide objective information, advice, and assurance to Parliament, territorial legislatures, governments, and Canadians. With our reports and testimony, we assist parliamentarians and territorial legislators in their work on the authorization and oversight of government spending and operations. The Minister of Finance is responsible for tabling the Auditor General’s administrative reports in Parliament, including the Departmental Plan and Departmental Results Report.

Under the Public Servants Disclosure Protection Act, the Auditor General has the mandate to investigate disclosures by public servants of alleged wrongdoing within the Office of the Public Sector Integrity Commissioner of Canada.

Professional practices

The OAG works with other legislative audit offices and professional organizations, such as the Chartered Professional Accountants of Canada, to advance legislative audit methodology, accounting and auditing standards, and best practices.

In addition, the OAG serves members of the Canadian Council of Legislative Auditors by offering methodology, training, and advice on request.

International activities

The OAG is actively engaged in international activities, primarily through its collaboration with the International Organization of Supreme Audit Institutions (INTOSAI) and engagement in peer reviews. These activities contribute to strengthening the OAG’s legislative audit practices, facilitating the sharing of knowledge, and increasing audit capabilities across supreme audit institutions.
