Raising Highway Speed Limits

This provincial government is raising the speed limit permanently from 100 km/h to 110 km/h on 10 additional sections of provincial highways in northern and southern Ontario.

The change builds on the safe and successful increase here in York-Simcoe on the 404 and five other sections of provincial highways in 2022 and aligns with posted speed limits in other jurisdictions across Canada.

Most of Ontario’s highways were originally designed to safely accommodate speed limits of 110 km/h and data from the changes in 2022 show they do just that.

These evidence-based increases are a common-sense change to make life more convenient for Ontario drivers while bringing our highway speed limits in line with other Canadian provinces.

The permanent increase in speed will cover 36 per cent and 860 kilometres of Ontario’s highway network.

All highway sections were selected based on their ability to safely accommodate higher speed limits.
