Hey - I've started a Steam group specifically for gamers from Ontario. I'm using it to help people find LANs or tournaments in their city and help hook up gamers that live near each other. Anyways, I don't know how many people here might be from Ontario but if you are, please join up and maybe we'll see each other at a LAN or something!
