Parts of southern Ontario are crawling out from under a blast of winter Monday that left thousands of people without power and caused chaos on Highway 400.
A major crash near Barrie, Ontario left several people with minor injuries.

Videos of the collision showed dozens of vehicles, including several transport trucks and one fuel tanker, smashed together, with numerous cars also in the ditch.
Authorities were dealing with other multi-vehicle pileups in other parts of the province Monday.
