Alberta's oil and gas is one of the cornerstones of the Canadian economy and without it Canada will struggle to pay her bills.
I wish we could annex British Columbia too in order to have a land connection between the lower 48 and Alaska, but the BC public is quite liberal thanks to Vancouver and would wind up being a Democratic stronghold if we were to annex it. So we can be content with Alberta sticking well up into the heartland of Canada, a sort of giant middle finger to Canadian socialism and the leftists in Ottawa.
The article points out that the numbers do not appear to be there for secession (and Canada has rules about seceding, which have to be addressed unless Albertans want to fight a war of independence). And it appears many Albertans aren't that interested in joining the U.S. yet, but that may change in due course.
Of course Texas will howl if we take Alberta into the Union; they would become the THIRD largest state. They were already fit to be tied over the entrance of Alaska into the union, bumping them from the top slot.
But annexation and statehood would be swift, provided Congress approved it. Alberta is not some frontier settlement but a thriving settled territory all ready to go. It would just need to write a new state constitution and buy some American flags. They could use the Canadian flags to wipe up any oil spills...
Meanwhile Quebec is renewing it's own independence demands, and should Quebec leave the Dominion Canada would become a wholly anglo nation and would be much more conservative, likely leading to the end of guys like Mark Carney's rein of error. We could only hope, anyway. Yes, BC and Ontario are no doubt still going to send lefties to Parliament but the balance of power would shift.
And Quebec is the center of at least 20% of the Canadian economy. So if Quebec leaves Canada will have to kiss the bottoms of the Albertans or risk the complete collapse of the country. If both leave that's the end of the Dominion of Canada (as it is formally known).
