The Ontario 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 to six sections of provincial highways in 2022 and aligns with posted speed limits in other jurisdictions across Canada, according to a news release.

“Most of Ontario’s highways were originally designed to safely accommodate speed limits of 110 km/h and the data from our changes in 2022 shows they do just that,” said Prabmeet Sarkaria, minister of transportation. “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.”

Starting July 12, 2024, the speed limit will be permanently raised to 110 km/h on most of the following provincial highway sections, with the remainder coming into force before the end of the year:

• Hwy 401, Tilbury, extending the existing 110 km/h zone further east by 7 km
• Hwy 401 from Hwy 35/115 to Cobourg (approximately 35 km)
• Hwy 401 from Colborne to Belleville (approximately 44 km)
• Hwy 401 from Belleville to Kingston (approximately 66 km)
• Hwy 401 from Hwy 16 to Quebec boundary (approximately 107 km)
• Hwy 403 from Woodstock to Brantford (approximately 26 km)
• Hwy 403 from Brantford to Hamilton (approximately 14.5 km)
• Hwy 406 from Thorold to Welland (approximately 13 km)
• Hwy 416 from Hwy 401 to Ottawa (approximately 70 km)
• Hwy 69 from Sudbury to French River (approximately 60 km)

All highway sections were selected based on their ability to safely accommodate higher speed limits. Alberta, Manitoba, New Brunswick, Nova Scotia and Saskatchewan have a maximum speed limit of 110 km/h, while in British Columbia, the maximum speed limit is 120 km/h.

Speed limiters on trucks

Trucks operating in Ontario and Quebec have had to mechanically govern their speeds at 105 km/h since 2008. Speed limiters were mandated in B.C. on April 5.

The permanent increase in speed from 100km/h to 110km/h will cover 36% and 860 kilometres of Ontario’s highway network.

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.
