The Alberta tar sands hold much of Canada’s oil wealth: the region contains an estimated 1.7 trillion barrels of bitumen oil. The size of this reserve makes it the third largest oil deposit in the world after Venezuela and Saudi Arabia. Yet despite this, the cost of extraction now outweighs the profit made per barrel.
