I'm in Ontario... the ones I go to are:
Fallsview Casino Niagara:
http://www.fallsviewcasinoresort.com/
They have blackjack, but its hard to get a table unless you play high limits. Also, very rarely have low limit tables.
Great Blue Heron Casino:
http://www.gbhcasino.com/
Have several BJ tables. Usually easier to get a seat and also have lower limits.
Casino Rama
http://www.casino-rama.com/home.aspx
Lots of tables, lots of limits.
Also, when the Exhibition is in town, there is the Casino at the Ex. Very bad (rookie) dealers, could probably take advantage of that :D
