Guess you do.. had to google it:

Profits derived from bookmaking or from the operation of any
gambling establishment (carried on legally or otherwise) constitute
income from a business. In addition, an individual may be subject to
tax on income derived from gambling itself, if the gambling activities
constitute carrying on the business of gambling; see the decision of
MNR v. Morden, (1961) CTC 484, 61 DTC 1266 (Ex. Ct.). The issue of
whether or not an individual's activities are such that he or she can
be considered to be carrying on a gambling business is a question of
fact that can be determined only by an examination of all of the
circumstances and the taxpayer's entire course of conduct. Although no
one factor may be conclusive, the following criteria should be
considered in making the determination: (a) the degree of organization
that is present in the pursuit of this activity by the taxpayer,
(b) the existence of special knowledge or inside information that
enables the taxpayer to reduce the element of chance,
(c) the taxpayer's intention to gamble for pleasure as compared with
any intention to gamble for profit as a means of gaining a livelihood,
and
(d) the extent of the taxpayer's gambling activities, including the
number and frequency of bets.
