I know there are some regular players because there was just a tournament at Flint's a few weeks back.
Be sure to join the Ontario Facebook group: https://www.facebook.com/groups/803949259653009/. A lot of the events are in Toronto but not all. It is probably not worth making the trip for a single game but hopefully you can make it out to tournaments where you will get 3-4 games in. There are some really good players but it is still pretty casual and the community of players is great for helping newer players get into the game.
The next tournament is actually scheduled for October 28th at 401 Games in Toronto (http://www.401games.ca/events). It is not far from the 401 (obviously) if you're driving and on a subway line if you are taking public transit. I am a newer player as well so hope to see you out there.
