Agree that Toronto is lovely, but 113km is a curious definition for "stone's throw"... Especially given the 401's proclivity for stop-and-go traffic...
I went to Waterloo for school and used to make the drive to TO regularly - under an hour is a very optimistic estimate that probably relies on some fortuitous celestial alignment.
In any case I also wouldn't describe Berkeley-SF as a "stone's throw" either...
Which is actually a great example - many a person has moved out of SF for Berkeley, because "I'll be around all the time, it's not that far" - only to be rarely seen again.
The "work/live in Loo, hang out in TO" thing is mostly theoretical, though I'm sure you can find a few people who actually do it.
