The Ontario Securities Commission (OSC) is the statutory body responsible for regulating Ontario's capital markets in accordance with the mandate established in the provincial Securities Act and the Commodity Futures Act. The mandate of the OSC is to provide protection to investors from unfair, improper or fraudulent practices, to foster fair, efficient and competitive capital markets and confidence in the capital markets, to foster capital formation, and to contribute to the stability of the financial system and the reduction of systemic risk. This mandate is performed through policy, operational, and enforcement activities. The OSC also contributes to national and global securities regulation development.

We offer a diverse, fair, and flexible work environment and take pride in our challenging and rewarding work.

Summer Accounting Student positions will be available in the below divisions. These positions may offer experience aligned with the foundational experience requirements needed for the CPA designation.

Registration, Inspections and Examinations

The Registration, Inspections and Examinations (RIE) division is a regulatory division that oversees dealers, advisers and investment fund managers, derivative firms and other market participants in Ontario that the public relies on when investing in securities. RIE is also responsible for the oversight of market infrastructure entities, including marketplaces, self-regulatory organizations (SROs), and clearing agencies.

The division reviews public distributions of securities, exempt market activities and continuous disclosure of reporting issuers, and leads issuer-related policy initiatives.

Enforcement

The Enforcement division investigates and litigates breaches of securities laws in Ontario. Team members work closely with other securities regulators, SROs and law-enforcement agencies to enhance initiatives to fight misconduct. A strong visible enforcement presence assists in protecting investors from unfair, improper or fraudulent practices, fosters fair, efficient and competitive capital markets, fosters capital formation, and contributes to the stability of the financial system and the reduction of systemic risk.
