The growing risk of tornadoes in Canada

It was a late summer evening when James Blacksmith was travelling along a prairie highway. The Manitoba man saw nothing out of the ordinary, save for a black cloud right above him. Suddenly, a massive wind kicked up and he was forced to pull off the road. Then a tornado struck. 

What follows is a story of survival and discovery. And while scientists aren’t sure yet what role climate change plays when it comes to tornados - they are observing changes. In Canada, researchers say these shifts, along with a growing population, are making people more vulnerable. Leading some to ask: is the country doing enough to warn Canadians of the risks?
