It's for all of Canada, and the international community to decide, and the requirements that a province needs to fulfill make separation legally impossible.

Add to that the fact that Alberta would be immediately annexed or even worse, turned into a conflict zone and then annexed makes talk of separation even more stupid. Ask yourself, how is Alberta going to defend itself when the largest organized fighting force left is the Alberta provincial police?

Thirdly, the economy would collapse overnight, since Alberta (the country) has no currency, and all resource contracts are with Alberta (a part of Canada), not Alberta (the country). Alberta would have to re-negotiate resource contracts with all the companies in it's (theoretically) only profitable sector in a currency that doesn't exist and no other country in the world trades in.

That's not even counting the fact that Alberta (the country) wouldn't even exist after separation since a country needs to be recognized as a country by other nations. What would likely happen is Russia and probably a couple other BRICS countries would officially recognize them and the US would immediately move to invade and annex the province to get to the oil sands. The end result of that is Alberta becomes (at best) a US territory, but more likely a vassal state or simply a war zone if the remainder of Canada decides it wants to push it's claim to re-take Alberta... as a territory.

But, all of that is still virtually impossible, as Canadian law as well as rulings from the Supreme Court have clearly laid out what is required to even start considering separation, and the federal government can still unilaterally reject it.
