Ontario is one of the most strictly regulated regions for retail forex trading in North America. The Ontario Securities Commission (OSC) enforces some of the toughest compliance rules globally, limiting retail access to many popular international brokers. As a result, finding the best forex brokers in Ontario means identifying firms that are legally registered, OSC-compliant, and offer competitive trading conditions under Canadian regulations.
