Actually, quite a ways from Toronto - I'm in Thunder Bay - around 1500 km and a world away from To.

Very active cycling group here; Club that I get out with when I can has weekly tour rides (mostly road bikes) although they do have some scheduled rides later in the season with routes more suitable for MTB. A couple other organized groups as well. Started commuting a couple of days a week and am surprised at the number of cyclists doing the same.

I'm rather envious of your more temperate climate and MUCH longer season in Vancouver - we're hoping for a long fall this year!
