A pilot project that will see a slight bump in speed limits on some of Ontario’s highways will go into effect later this week, the province’s transportation minister said Tuesday. Caroline Mulroney said the new rules, meant to bring Ontario in line with some other provinces, will take effect on three stretches of highway beginning on Thursday. They include a 90-kilometre stretch of Highway 402 between London and Sarnia, 32 kilometres of the Queen Elizabeth Way between St. Catharines and Hamilton, and the 102 kilometres of Highway 417 between Ottawa and the Quebec border.
