Effective January 1, 2009, both Ontario and Quebec began requiring that commercial motor vehicles operating within those provinces be equipped with speed limiters set at 105 km/h, which equates to 65 mph. The regulations were subject to an educational period of soft enforcement, but are now being enforced in both provinces. Importantly, the rules are not limited to vehicles based in either province. Thus, for instance, a U.S. based vehicle operating in either province pursuant to Canadian authority is subject to the commercial vehicle safety measure. Fines vary in each province. The regulations will be enforced by enforcement officers that will plug a portable testing device into the vehicle's Electronic Control Module.
