Maybe there's just a ton of gamers there. Down here the larger cities have a higher number of gamers.
Also could be that they are searching based on distance from them. I think that there's a feature that can be enabled to search based on that to find local gamers.
Maybe Québec geeks are more used to checking people's profiles (to verify if they speak french?), whereas other Canadians don't have this urge as everyone here speaks english anyway ? Just an idea.
