Ontario is increasing the speed limit of six sections of highways in southern Ontario to 110 km/h from 100 km/h beginning April 22, 2022.
At the time, the province will also raise the speed limit of select sections of highways in Northern Ontario to 10 km/h on a trial basis.
The province says the change follows consultations with other jurisdictions across Canada and a pilot project which raised speeds of three sections of 400-series highways beginning September of 2019.
The province also held a public survey and according to the news release, 80% of the people who participated in the survey supported the raised speed limit pilot.
Sections of highways where the speed limit will be raised to 110 km/h permanently:
- Queen Elizabeth Way (QEW) from Hamilton to St. Catharines (32 km)
- Highway 402 from London to Sarnia (90 km)
- Highway 417 from Ottawa to the Ontario/Quebec Border (102 km)
- Highway 401 from Windsor to Tilbury (approximately 40 km)
- Highway 404 from Newmarket to Woodbine (approximately 16 km)
- Highway 417 from Kanata to Arnprior (approximately 37 km)
Sections of highways where the speed limit will be raised to110 km/h on a trial basis:
- Highway 400 from MacTier to Nobel (approximately 55 km)
- Highway 11 from Emsdale to South River (approximately 45 km)
Currently, six other provinces – Alberta, Manitoba, New Brunswick, Nova Scotia, Saskatchewan and British Columbia – have posted speed limits of 110 km/h (~68 miles per hour).
