To other Vancouver players: I spoke with a local accountant who was recommended through a locally-based poker internet forum. She indicated that income from gambling, including poker, is not taxable unless it is your only or primary source of income, as determined by the number of hours you spend working for your taxable income. I told her I work 27 hours a week in addition to playing and she said it was close enough to full-time that I could claim my poker winnings were windfall rather than taxable income.

This advice is contradictory to what has been offered in this thread, however I am inclined to take it since it is beneficial to me and it is the only "official" advice I have received.
