Blazes in the oil sands region have led to evacuations and government action.

Wildfires in Canada’s oil sands region have forced tens of thousands of people from their homes. The city of Fort McMurray, Alberta, was evacuated this week as the flames engulfed homes, businesses, and acre after acre of forest.

Canadian Prime Minister Justin Trudeau has pledged support for the victims of the fire, promising to match Red Cross donations with federal funds. Meanwhile, the evacuees continue to move south, pushed by the natural disaster.
