About


The Ontario Securities Commission (OSC) is an independent Crown corporation that is responsible for regulating the capital markets in Ontario. Our statutory mandate is:

To provide protection to investors from unfair, improper or fraudulent practices and to foster fair and efficient capital markets and confidence in capital markets.

We contribute to the health and performance of Ontario’s economy by using our rule-making and enforcement powers to help safeguard investors, deter misconduct and regulate participants involved in capital markets in Ontario. We regulate firms and individuals who sell securities and provide advice in Ontario. We also regulate public companies, investment funds and marketplaces, such as the Toronto Stock Exchange.

Our powers are given to us under the Securities Act (Ontario) the Commodity Futures Act (Ontario) and certain provisions of the Business Corporations Act. We operate independently from government and are funded by fees charged to market participants. We are accountable to the Ontario Minister of Finance.

The history of the OSC dates back to 1928 when the Government of Ontario introduced the Security Frauds Prevention Act. The province’s securities regulator, the Security Frauds Prevention Board, was renamed the Ontario Securities Commission in 1933.

Our goals

  1. Deliver strong investor protection
  2. Deliver responsive regulation
  3. Deliver effective compliance, supervision and enforcement
  4. Promote financial stability through effective oversight
  5. Be an innovative, accountable and efficient organization

Our priorities for the current year are set out in our Statement of Priorities.
