Ontario Securities Commission

The Ontario Securities Commission (OSC; French: Commission des valeurs mobilières de l’Ontario) is a regulatory agency which administers and enforces securities legislation in the Canadian province of Ontario. The OSC is an Ontario Crown agency which reports to the Ontario legislature through the Minister of Finance.

Canada does not have a national securities regulator, and each province and territory regulates its own capital markets; OSC regulates the capital markets in Ontario.^[3] Other notable provincial regulators include the Alberta Securities Commission, the Autorité des marchés financiers (Québec), and the British Columbia Securities Commission.

The OSC's mandate is to:

• Protect investors from unfair, improper and fraudulent practices
• Foster fair and efficient capital markets
• Maintain public and investor confidence in the integrity of those markets
• Contribute to the stability of the financial system and the reduction of systemic risk

The OSC administers the Ontario Securities Act and the Commodity Futures Act and with about 500 employees,^[4] is the largest securities regulator in Canada and has the Toronto Stock Exchange within its jurisdiction.

From inception, the OSC was run by a chairman who was the de facto chief executive of the commission. Following the proclamation of the Securities Commission Act, 2021 on 29 April 2022, a separate chief executive officer was created and the chairman became a non-executive office.
