Card counting is not illegal in Canada but it is almost useless to try it. They use 8 decks of cards and cut 2 or more out of play. You can try Wonging it if you want to, but doing so against 8 decks can get very boring. It also will probably get you barred if it looks like you are having very much success.
But the news isn't all that Current for most. The only locations that have been updated in the last 12 months are Vancouver BC (8 casinos, Jan. 2005), Niagara Falls ON (3 casinos, 1 in U.S., Oct. 2004), and Victoria BC (1 casino, May 2004). The most out-of-date is Quebec, which hasn't been updated since Oct. 1998.
Of course, you can join CBJN, and then pay for your subscription by filing updates... that's what I do. According to the CBJN page, you can earn between $8 and $47 (depending on location and number of casinos) for Canadian reports on locations that have not been updated in at least two months... and those are U.S.$!
