Hey Erin!
The groups I've come across so far seem to be internet-based, but I'm sure there's potential to meet face to face once you decide which group you'd like to join. The first link below outlines options in the Toronto/York Region area as far as home school support groups go. I don't know if you're religious/non-religious so feel free to hunt around as there seems to be groups within both categories. The second link is an unschooling channel through YouTube that may have some more research information. I haven't looked into it yet myself so I don't know what type of info you'll find there...
Let me know if any thing interesting comes up from your end - ie books, links, groups, etc.
Thanks!
