How would global warming affect the settlement patterns of Canadians?

The global warming is not a problem for Canada, because with almost 10 million square kilometers it is the second biggest country in the world, while 33 million people barely cover any of the available space.

The regions where the settlement could not be extended

1.  Cordilleras, where mountains make it significantly harder to settle there, because it is colder and it is harder to build houses there. From the climatic aspect the Cordillera region is the best one for settlement which would cause lots of people to go there. But only the small area where there are no mountains can be used for living space, so the population density would rapidly increase.
2. In the Canadian Shield the temperature is very similar to the Interior Plains, where there are lots of people living, but it is not possible to build houses or grow foods because the ground is rocky. The Interior Plains would still provide lots of room for new inhabitants as Canada warms up. Right now, the Settlement in that region extends from the border to the United States to North from Edmonton. North from there it is way too cold to live there, but the climate change might warm Northern Canada up so much that Settlement might get possible far north from Edmonton, so that would provide lots of room for living.
3. Since the temperature makes it nearly impossible to settle, the global warming would cause huge regions in Northern Canada to provide room where people can live. The temperature would rise to what it in the Interior Plains right now and there are lots of people permanently settled.
