2016 Fort McMurray wildfire Reuters reports that Alberta Province, which projects a C$10 billion deficit this fiscal year as the prolonged slump in oil prices has reduced tax revenue, last month cut funding for wildfire prevention, including millions for programs created in response to the province's Slave Lake wildfire in 2011, which destroyed more than 300 homes.
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.
The western Canadian province of Alberta declares a state of emergency as devastating wildfires, fed by unseasonably hot temperatures and dry conditions, grow to five times their initial size. The mandatory evacuation order expands to include the communities of Anzac, Gregoire Lake Estates, and Fort McMurray First Nation, forcing thousands who had just resettled to move again.
