I've never lived in Toronto, but I have family who live there and I live in a city not far down the road from TO. For a brief period over a decade ago I lived in Oakville which is a suburb of Toronto, but that's as close as I got.
Toronto is a great city to visit, spend the day shopping and walking around, but I could never live there. I'm just not a big city gal. I prefer where I live now, size-wise (an urban area with a population of about 140,000.)
