Ontario traders operate under the national CIRO framework with the Ontario Securities Commission as the provincial regulator — one of the most active in North America against offshore platforms.

All five brokers in our comparison matrix accept Ontario residents. There are no Ontario-specific product restrictions for forex beyond the national rules.
