Not only does it undermine Canada's sovereignty, it would I believe be open to a court challenge if a government decided to confer nationhood status and all that it implies on a segment of the population and then made the taxpayer responsible for the upkeep of that nation. The people of Canada would need to first be consulted then given the opportunity to express their wishes in a referendum. Winning an election would not be sufficient to undertake such a drastic alteration as to what Canada is.
