glorious revolution 2.0   if they would support it then it's not really that absurd. a few battalions could just walk into ottawa (in full parade dress because it's a purely symbolic show of force that won't be resisted) and politely demand a referendum to be issued by the parliament (which has been fully independent since 1982 so it doesn't need to ask for the uk parliament's permission or anything). not one drop of blood spilled.
