I'm not in Canada.. but wanted to comment..
I'm in a relationship with a delightful couple..and on okcupid. But I wouldn't have found my couple on okcupid because they are completely outside my search criteria there.
So when you are disappointed with what you find ... open up your options.
Specifics: my okcupid profile is looking for guys who like girls, , 45- 60 (my couple are 35 and 40), near me (they live an hour away). Recently we were talking and I admitted that there are several things about them that would have kept me from dating them... But once I knew them...the conversations were a turn on.
Living near a major city with a thriving poly community has helped tremendously. And having a poly group that acted as a match maker helped also.
