If you are wondering where to meet poly people in your area, you might try our Dating & Friendships subforum
. Also you could google "Toronto polyamory" and see what turns up. There may be a group nearby that meets for social events.
As for jealousy, it happens from time to time, but it doesn't have to spell disaster; people have learned to handle it appropriately. First thing to figure out is how much of it is external and how much is internal; but really, you'd just cross that bridge if/when you get to it.
You can always turn to Polyamory.com for help on various issues. You can do thread searches, tag searches, browse through the various boards, and post whenever you have a thought/question/concern you want to share.
I hope we are able to help.
