Canada's rise to superpower status is largely because of climate caused migration from the rest of the Americas. Much like Sinosiberia, most of the population is 1st or 2nd generation climate refugees. Thanks to climate change most of the country is now habitable. Canada's territory includes Alaska, parts of the northern United States and a number of overseas territories. Quebec was independent country of its own since the mid-2040s, but the growing movement for it to rejoin Canada resulted in re-unification in 2094. Canada's political system is a combination of the early 21st century, Canadian, and the American political systems, with a number of European influences.
