A massive wildfire in western Canada is expected to double in size by late Saturday as shifting winds push it northeast — away from the fire-ravaged Alberta community of Fort McMurray but straight into heavily forested areas offering fresh fuel.
Nearly 90,000 people have been evacuated from the area in the heart of Canada's oil sands region, with some forced to relocate twice as the flames shifted.
The fire so far has destroyed about 1,600 buildings and homes.
The mass evacuations forced as much as a quarter of Canada's oil output offline.
The region contains the third-largest reserves of oil in the world, behind Saudi Arabia and Venezuela.
No deaths or injuries have been reported.
