The auditor's office was created in 1869. Before 1886 the Auditor’s Office was an adjunct of Treasury Department. Since the passage of the 1886 Audit Act then the office has evolved (after the 1950 Audit Act) into an independent provincial agency. The office is located in Toronto, Ontario. With the passage of the 1978 Audit Act, the auditor general no longer submitted his findings to the provincial cabinet, but to the Speaker of the Legislature of Ontario (and thereby report back to the Legislature).
