Toronto-area drivers headed up north this weekend will be getting there a little bit faster. As of Friday, on Highway 400 between Highway 401 to Lake Joseph Road, the speed limit will increase to 110 kilometres an hour.Highway 400 is among four other highways where speeds will be increasing including Highway 115 from highway 35 to Parkway Interchange in the east end of the GTA.It’s part of the Ford’s government sweeping expansion of 110 km/h speed limits that has been rolled out in phases over the summer.Ontario first tested higher limits in 2019 on three highway segments, then expanded the program in 2022 and again in 2024. Those expansions covered roughly 860 kilometres – about 36 per cent of the network – and included stretches of the QEW, Highway 402, Highway 417, and Highway 404.The following highways will also have their speeds increased later on this summer:Aug. 31, 2026Highway 401 from Merlin Road to Hwy. 427Highway 401 from Highway 404 to Hwy. 35/115Highway 401 from Cobourg to ColborneHighway 401 from Sidney Street to CNR Overhead Bridge in BellevilleHighway 401 from County Road 38 to Hwy. 15Highway 403 from Hwy. 401 to Middletown LineSept. 30, 2026Highway 403 from QEW to Hwy. 401Highway 404 from Hwy. 401 to Mulock DriveHighway 406 from Westchester Avenue to Hwy. 58Highway 407 from Brock Road to Hwy. 35/115Highway 412 from Hwy. 401 to Hwy. 407Highway 418 from Hwy. 401 to Hwy. 407QEW from Freeman Interchange to Hwy. 403QEW from Concession Road to McLeod RoadQEW from Mountain Road to Jordan Road
