Canada's New Road Construction Method Could End Potholes Forever

Every spring, Canada fills hundreds of thousands of potholes. Toronto alone filled more than 250,000 in 2025. Bad roads cost Canadian drivers about $3 billion a year. But Canadian engineers have been quietly testing a different kind of road. On Highway 401 near Woodstock, Ontario, the province built a road in 2009 that was designed to last 50 years, and the University of Waterloo buried sensors inside it to listen to every truck. In Kingsey Falls, Quebec, researchers from Université Laval put a layer of recycled glass under a test road to stop frost heave. And in the Yukon, engineers learned how to build a highway that breathes out the heat on frozen ground. So can a Canadian road really end potholes forever? And why is your street still full of them?

It is not a real project and no city is building it.
