Ontario is raising speed limits from 100 km/h to 110 km/h on 938 kilometres of highway across the 400-series network, one of the largest expansions in the province's history.
The first change for the Ottawa area takes effect June 26, on Highway 416 from Cedar Grove Road to Highway 401. Highway 416 from 1.5 kilometres south of Fallowfield to County Road 12 will increase on August 21.
On Highway 417, the changes apply from the 416 split to Highway 7 through Ottawa's west neighbourhoods, including Highway 7 to Appleton Side Road/County Road 17. In the east end, Highway 417 from Leitrim Road to Highway 174 will also increase. The move builds on earlier expansions in 2022 and 2024 that followed a multi-year pilot project showing select highways could safely accommodate higher speeds. Further roadways across Ontario are scheduled throughout the summer, with additional sections on Highways 401, 402, 403, 416, 417, and the Queen Elizabeth Way to follow by the end of September.
