Not a bad idea. Alberta is so frigid in the winter, its replacing California would lower the average national temperature by enough to eliminate the effects of global warming in the US!
I’d go even further. Break up Canada. The western provinces, BC, Alberta, Saskatchewan,and Manitoba would become states. Ontario would remain as the nation of Canada, while Quebec and the eastern provinces would become French Canada. Though without transfer payments from Ottawa, provinces like PEI, Nova Scotia, and Newfoundland, maybe even New Brunswick, would become economic basket cases that even the northeastern US states would take a pass on.
Culturally, neighboring US states and their Canadian counterparts have more in common with each other than their east-west orientated populations. Do it, already, eh?
