> there is no legal mechanism by which Canadian provinces can unilaterally secede

Legal? Who's laws? Albertans can just declare that they don't respect Ottawa's authority, right?

Guns and bullets are the only "legal" currency. It's not paperwork.

Sure, but just like nobody gives a shit about what Sovereign Citizens do or do not respect, such a declaration would only carry weight if there are enough people that want to mount an armed rebellion. And despite what American influence operations would have you believe, there simply aren't. Most Albertans want to remain in Canada.
