This whole Alberta separatism thing feels very similar to separatist actions in former Soviet-bloc nations:
Russia has this pattern of supporting "separatist" movements in nations where it wants to carve out some territory. They get agents embedded with local malcontents and stir up trouble, eventually legitimizing themselves as a political movement, and then destabilize the national government.
I don't have any evidence that actually links Russia to Alberta, but we know that Russia has intent to destabilize Western nations and to me this fits the pattern:
Russia should use its special services within the borders of the United States and Canada to fuel instability and separatism against neoliberal globalist Western hegemony, such as, for instance, provoke "Afro-American racists" to create severe backlash against the rotten political state of affairs in the current present-day system of the United States and Canada. Russia should "introduce geopolitical disorder into internal American activity, encouraging all kinds of separatism and ethnic, social, and racial conflicts, actively supporting all dissident movements – extremist, racist, and sectarian groups, thus destabilizing internal political processes in the U.S. It would also make sense simultaneously to support isolationist tendencies in American politics".
