I noticed a bunch of commuters from Toronto, but I don't think I'd want to meetup for my commute ride - I like the alone time.
I would love, however, to ride recreationally with anyone - I signed up on cyclingcog.net which has a 'ridematching' thing on and seems to be local to Toronto.
Once my wrist is healthy again, I'll be keen to ride with others just to gauge how badly I suck
