OK, but there are some logistical issues here- let's say Alberta votes to secede and this is somehow legally viable. All of the Albertan voters who didn't want to secede- including the native tribes- could then by your rules vote to secede from Alberta and join back to Canada. It'd be a mess. Towns and counties would split themselves in half, and so on.
What would happen if a landlocked town within Alberta wants to rejoin Canada- how would you handle that?
