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?

It's like having to belong to a higher imposed authority (either the original country or the seceded territory) is bad for the individual that doesn't want any of that. If only there was a solution to that problem...

Eh, it ain't ever happening anyways, this is just the UCP and other assorted wack-jobs playing games with Ottawa again.

All the Oil Sands land is treaty land, so First Nations get it if we leave.
