About us

The Ontario Securities Commission (OSC) is an independent Crown corporation that regulates Ontario’s capital markets by making rules that have the force of law and by adopting policies that influence the behaviour of capital markets participants.

The OSC exercises its regulatory oversight function through the administration and enforcement of Ontario’s Securities Act and Commodity Futures Act and administration of certain provisions of Ontario’s Business Corporations Act.

Our statutory mandate is:

To provide protection to investors from unfair, improper, or fraudulent practices, to foster fair and efficient capital markets and confidence in capital markets, and to contribute to the stability of the financial system and the reduction of systemic risk.

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

Our Goals

  1. Promote confidence in Ontario’s capital markets
  2. Reduce regulatory burden
  3. Facilitate financial innovation
  4. Strengthen our organizational foundation

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