Have you looked at the forum here for updates on poly groups in Toronto? Is there any other groups than the one you are in?
What is it that you are not interested in about the group/s you have found? Just that the people are coupled? Are they not looking for poly-fi then? Or is there something else?
Sorry for all the questions, I just am trying to get a grasp on what the issue is.
You could start your own group. Even if its just to meet for coffee at first. Put the word out there that you will be meeting at a certain time and place for a specific purpose and see where you get. This is where groups start. It's where I started in creating my community. It really works. I have made some great friend and meet loves that way.
