The best "true" sports bar is probably the Varsity Sports Bar and Grill, but that's all the way over at the beginning of the B concourse. They'll probably be playing your game, but it'll be a bit of a hike coming from the customs/immigration area. It is all behind security, though.

Let me know if you'd like detailed instructions on how to get there. Otherwise, you can use the maps/links above to make your way there. I do recommend walking to the beginning of the C concourse and taking the tram the whole way from the beginning of C to the beginning of B, though.
