Welcome to our forum.
Might I suggest the Dating & Friendships subforum
? It might help you get connected with some of the poly people in your area.
Other things you can try:
And you can google "Vancouver polyamory" and see if any other local poly groups come up. Somewhere in there you should be able to get a chance to meet poly people in your area and maybe even snag a couple of dates.
Hope your time spent with us on Polyamory.com will be helpful.
