I beg to differ. Not ALL Canadians live right on the US border. Where did you get your stats? Edmonton,for instance, has over a million residents and this city ,for its size, is the furthest north of any such in the world and it is growing by leaps and bounds.
Fort McMurray,near the tarsands, has over a 100,000 citizens and is one of the fastest growing cities in N.America. We are a huge country,with vast resources,but we do have great summers. We are not all ice and snow . No need for all of us to crowd the US border,for what reason?
