Well i know theres a few rooms in Calgary here. Only need to be 18. I've only been to the one and it was alright nothing special apparently the other rooms are nicer, they have twice daily rebuy tournaments(20,30$) and run some 4/8, 5/10 and 10/20 depending on demand if i remember correcrly.
I'm pretty sure there are atleast 2 more rooms and another casino opens up this weekend or last i believe and due to the fact its a 30+ minute drive away i havent gone to see it yet.

Apparently Vancouver has a pretty good poker room. Atleast a lot of the stars play there when they are out shooting movies on the coast.
