Growing up in Calgary but visiting family in Toronto pretty much every summer, I always considered Southern Ontario to better fit my stereotypical idea of "Canadian". Calgary didn't particularly feel this way as the climate always seemed at odds with "the East".

I'd agree with most posters that Ottawa-Gatineau is up there, but I may actually put Toronto first. Acajack summed up why quite well. I'm also increasingly of a mind that there probably have to be two distinct answers to this one...
