The real political theatre is coming from Alberta. Secession can't be achieved unilaterally under Canadian constitutional law. A clear majority on a clear referendum question would create an obligation to negotiate.

More critically, the Numbered Treaties (6, 7, and 8, and to a lesser extent 4 and 10) make the entire idea, for all practical purposes, a legal dead end. These are nation-to-nation covenants with the Crown and not with the province.

To leave with its borders intact, Alberta would have to negotiate constitutional amendments with Ottawa and the other provinces, while securing affected First Nations’ consent to any transfer or replacement of their treaty relationships with Canada in a situation where Alberta has almost no leverage.

Good luck.
