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.
The CSA operates, through various agreements, a number of shared information technology systems that serve securities regulatory purposes and functions. These CSA National Systems are the primary interface between regulated entities and each provincial and territorial regulator. In addition, many of the systems provide information to other market participants including institutional investors and the public.
The operations, maintenance, and enhancement of the CSA National Systems are managed by the CSA IT Systems Office which is co-located within the premises of the Ontario Securities Commission.
