Ontario’s phased speed limit increase to 110 km/h is designed to improve travel efficiency while maintaining safety standards. The expansion covers nearly 89% of the provincial highway network by the end of September 2026, with careful selection of highways based on engineering assessments and public consultation. Drivers should continue to follow all traffic laws, including speed enforcement and stunt driving regulations, while benefiting from reduced travel times on major routes
