With forecasts that the Bay Area's climate will resemble San Diego's in a few decades, and a similar knock-on effect as you go northwards, maybe provinces like Saskatchewan and Manitoba will become major growth areas.
I've been thinking the same thing, that Canada is poised for significant growth, though I suspect that the great majority of North America's growth will continue to occur closer to the coasts (and in Canada the Great Lakes), as the central states and provinces seem to have a harder time attracting new residents. The major exception to this is Texas, and to some degree North Dakota due to the shale boom there.
I expect that BC/Alberta and Eastern Ontario/Quebec will attract the majority of the population growth, but I won't be surprised if there's a considerable increase in the 'plains' states in the middle as well.

So, while agriculture will move northward, I don't think people will be quick to abandon southern cities. For instance, while I as an outdoors person would consider Phoenix to be uninhabitable, it continues to grow. Of course, that means more and more people using cars to transport A/C from building to building. I suppose that's far more pleasant than being confined to a possible settlement on Mars, however.
It will be interesting to see if the sunbirds choose to travel TO NYC for the winter, in future In the case of a city in the desert southwest like Phoenix, water shortages will limit population growth before energy usage does. They're already running as fast as they can to stay in the same place, trying to build infrastructure to import water from quite long distances, as their existing sources are oversubscribed now.
