As someone living in Alberta your comment answers a question we ask each other frequently: Do people outside of Alberta understand the benefit they've enjoyed from energy revenues over the past 20 years?
Your comment suggests NO, but I'm not sure where you are located.
Canada has a massive transfer payment process from "Have" provinces to "Have Not". This is not something as academic as "overall GDP increase" but is BILLIONS of actual dollars that Alberta has contributed during all the good times that were then redistributed to other Canadians, just like people living in Toronto. Not to over-emphasize the point, but I'm talking cold hard cash literally taxed from one province and given to the others, with the Federal government taking their vig during the transfer.
If you're not Canadian it's unlikely you are aware of the direct positive impact this has had on the entire nation. If you are Canadian and unaware of the relative value of transfer payments... well, this accounts for a huge amount of the alienation the Western prairie provinces are feeling.
This is an issue outside of the debate around where our energy comes from. The reality is a huge part of the entire country's expenditures has been financed by oil and gas revenues for a large part of the past 20 years.
