Canadian Online Poker Tax Thread
If I remember right, someone (raze maybe) posted about you only have to pay taxes on winnings if you are a professional or something, but I wouldn't take that as the rule. Look through that thread, post a question if you don't find your answer. If you still don't have an answer and you run into this problem, spend a small amount of money and get a tax professional to consult you about it.. it really shouldn't take longer than a few minutes and a small amount of $ to have your questions answered if you have this "problem".
