I found this video to be interesting. Douglas Coupland was asked the Canada-nation or notion question, particularly in light of the rise of CanCon cultural product exports. Coupland noted the rise of Vancouver as a place and the fluid dynamics of it as a changeable place that is likely to look quite different in the future, a characteristic that Canada shares as well.
