“King welcomes the province’s continued investment in improving transportation efficiency across Ontario,” King City Mayor Steve Pellegrini said Wednesday. “Expanding the 110 km/h speed limit to additional highway sections will help people and goods move more efficiently.”

“As communities like King continue to grow, initiatives like this help reduce travel times, strengthen economic connections, and support a modern transportation network that meets the needs of residents, businesses, and visitors alike,” he added.

Taking effect on Friday

Speed limit increases will begin taking effect incrementally from Friday until Sept. 30. 

Starting June 26, the province will begin increasing the speed limit to 110 km/h on sections of Hwys. 401 and 416 in Eastern Ontario, followed by sections of the Queen Elizabeth Way (QEW) and Hwys. 400, 401, 402, 403, 416 and 417.

“Our government is building new subways, highways, and GO transit to get Ontarians moving faster,” King-Vaughn MPP Stephen Lecce said. “This new policy builds on our actions to reduce congestion on our roads and save families time, all while maintaining safety on and off the road. Ontario was proud to complete the widening of Highway 400 from Highway 9 to Major Mackenzie Drive, along with building the Bradford Bypass, Highway 413, and the largest public transit expansion in North America.”

Currently, 873 kilometres of provincial highways are posted at 110 km per hour. Once in effect, nearly 89% of the province’s highway network will have a posted speed limit of 110 km/h. 

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/h.

All part of the plan

These changes are not new as the province raised speed limits on selected portions of highways in April of 2024 when 10 additional sections of highways across the province were increased to 110 km/h. 

On July 12, the speed limit was raised to 110 km/h on five sections of the 401, two sections of the 403 and one section of both the 406 and 416, followed by a 69-km stretch of Hwy. 69 between Sudbury and French River with the remainder coming into force by the end of the year.

In September of 2019, the province launched three speed limit pilot programs on sections of the 402, 417 and QEW to explore new ways to improve traffic flow on provincial highways.

Until 1975, Hwys. 400, 401, 417 and the QEW were posted at 113 km/h before being reduced due to the energy crisis. 

Stunt driving penalties will continue to apply at 150 km/h. On the highway sections with increased speed limits, stunt driving penalties will apply at 40 km/h over the posted speed limit.
