BB,
Don't know how it works in Toronto but here's an idea. Hold a weekly or monthly sing-along jam at your place. Invite anyone you think might be interested. If you are consistently meeting, you are bound to find musicians who want to check it out.
When you find out who you like jamming with, then you can keep running your session or go to theirs. The point is to cultivate those who are on your musical wavelength and you'll find out who there are if you run the sessions.
