As I said, Alberta has diversified a great deal since the 1980s, I think in large part due to lower taxes and lower regulations, but also from spinoffs from the wealth created by that oil sector. We are in a place where we have other things we do, of course, but it would have a pretty drastic effect, just as it would in any province if 25% of the economy was a certain industry and that industry disappeared tomorrow. It would be a pretty dire recovery for a decade at least, but Albertans are resourceful and hard-working and I'm sure we'd find a way to struggle back.
Looking at it the other way, it would be a real lost opportunity for Canada to continue to profit and have spinoff jobs from an industry that provides a product that the world is going to be wanting in copious amounts for another three decades at least.
