You figure that the Indigenous people are going to side with rootin'-tootin' armed assholes who think that it's their right to shoot injuns that wander across their ranches? You'll be lucky if you manage to convince one solitary native to side with you and lose the Protection of the Crown in favour of nothing from angry white nationalists.
That was one of the Federal Government secret weapons in the Quebec Referenda, as well. Native support of separation ran around zero and their trust of the French ran into the minuses. A seperate Quebec was going to be about a 200 mile side strip with UN mandated First Nations on all sides of them. Expect Alberta to look the same. Expect Alberta to lose some of even all of the Athabasca Sands to UN mandated First Nation control.
