The Office of the Auditor General of Ontario is an independent office of the Legislative Assembly that conducts value-for-money and financial audits of the provincial government, its ministries and agencies. We also audit organizations in the broader public sector that receive provincial funding, such as hospitals and long-term-care homes, universities and colleges, and school boards. In 2019, our mandate was expanded to include reporting on the operation of the Environmental Bill of Rights, 1993, including reviews of any environmental matters our Office considers appropriate. Our work helps ensure that taxpayers receive value for their tax dollars.

Bonnie Lysyk (MBA, FCPA, FCA, LPA) is the Auditor General.

Auditor General’s Office Working for the Legislature and Ontarians—July 27, 2020

We continue to work productively thanks to the co-operation of government ministries and agencies, which are doing their best to fulfil information requests for audits underway.

Our auditors are now working in our office and at auditee locations. We are reachable through our reception (416) 327‑2381 and public inquiry (416) 314‑5772 telephone lines. However, our office is not open to outside visitors without appointments at this time.
