Toronto is a great city. Very multicultural, lots of arts, great food, things to do.... I love it here. I work from my loft, so no commute, but public transit is pretty good, and it depends where you live and work how the commute would be.
FYI, Toronto was rated best city in the world to live / most livable by the Economist and Metropolis magazine.

It's not cheap to live here, but overall reasonable for most things like food, transit, etc. Housing not so much.
