The Ontario government is raising the speed limit from 100 km/hour to 110 km/hour on an additional 938 kilometres of provincial highways.

Crash that took place on a 400 level highway.

The change builds on the safe and successful increase to speeds on 10 sections of provincial highways in 2024 and six sections of provincial highways in 2022, aligning with posted speed limits in other jurisdictions across Canada. Currently, 873 kilometres of provincial highways are posted at 110 km/hour. Once in effect, nearly 89 per cent of the province’s highway network will have a posted speed limit of 110 km/hour, up from 43 per cent today.

Starting June 26, the province will begin increasing the speed limit to 110 km/hour on sections of Highways 401 and 416 in eastern Ontario, followed by sections on other highways, including the Queen Elizabeth Way (QEW) and Highways 400, 401, 402, 403, 416 and 417. With this new speed limit in place, drivers travelling from Sarnia to Toronto could save nearly 20 minutes, while those travelling from Toronto to Ottawa could save nearly half an hour.

Speed limit increases are only implemented on highways that have been designed and engineered to safely accommodate higher speeds, following rigorous technical reviews and any necessary infrastructure improvements. Most of Ontario’s freeway network was originally designed to safely accommodate a posted speed of 110 km/hour.

The problem is that drivers are not “designed and engineered to safely accommodate higher speeds”.
