It's Not Nostalgia, Exactly
I have spent most of my life in Montreal but there was a decent sized chunk in the middle, spanning high school and university, when I lived in Toronto.
I still visit Toronto not infrequently. I have a soft spot for it; at the very least, I don't harbour quite the same level visceral hatred a lot of people seem to lob at the city.
But I haven't lived there for over 20 years. Obviously, a lot has changed in that time. I'm not sure I could live there now. I mean, I guess I could but my life would look very different. The place is so huge, and the housing so expensive, that I'm not sure it would be a good trade.
