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.
