Canada Fire Deals Staggering Blow to Oil Sands Industry and Economy. (The New York Times, 5/11/2016)
Fort McMurray, the heart of the province’s oil sands production, plays an outsize role in the country’s prospects.
When oil prices were surging, the city and its vast reserves of oil sands fed an economic boom. Energy companies poured billions of dollars into projects and thousands of workers flowed into Fort McMurray.
But the oil slump of the last year brought an end to the prosperity. Even before the fire, the government projected an $8 billion deficit, in contrast to an $800 million surplus in 2014.
