the major (and so far as I know only) operating news group for U2 fans in Ontario is the U2_GTA group on Yahoo... as the name suggests membership is mainly in the Toronto area but it has members as far away as UK and California (I think there is one in Guatemala too). This is an amazingly active group which has social events, film viewings etc. all year round and was responsible for the U2 fan fest thing that happened in Toronto a couple of weeks ago so if you're interested I suggest you go to http://groups.yahoo.com/group/U2_GTA/ and sign up. It's free, you'll find out about any and all U2 related events in Ontario and if you don't like it you can leave anytime. So give it a whirl.
