Since the fire has intermittently blocked the only route south toward Alberta's major cities, evacuees have had to go north toward oil camps and a few small settlements. The province has airlifted 4,000 people to Edmonton and Calgary as of late Thursday. Roughly 20 percent of Canada's crude oil production, around 680,000 barrels per day, is offline and is expected to increase. There are no known casualties from the fire, which today has grown to 210,000 acres (85,000 hectares), but fatalities are reported in at least one vehicle crash along the evacuation route.
