According to the Criminal Code, R.S.C. 1985, c. C-46:
365. Every one who fraudulently
(a) pretends to exercise or to use any kind of witchcraft, sorcery, enchantment or conjuration,
(b) undertakes, for a consideration, to tell fortunes, or
(c) pretends from his skill in or knowledge of an occult or crafty science to discover where or in what manner anything that is supposed to have been stolen or lost may be found,
is guilty of an offence punishable on summary conviction.
As such, if you engage in witchcraft, sorcery, fortune telling, or other similar activities, you must actually perform such as it is unlawful only when someone "pretends". Note that this law is applicable 365 days a year without exception for Hallowe'en!
As an offence punishable on summary conviction procedures, the maximum fine is $5,000 and/or six months imprisonment in the most tortuous of deathly dungeons!
If you are charged with pretending to engage wizardry, sorcery, fortune telling, infliction of magic, call Scott McEachern, Licensed Paralegal for assistance. Scott's team of hocus-pocus legal professionals can "pretend" to spell bind any judge into issuing the most lenient sentence possible.
Note: The above is satirist for entertainment purposes only - Scott McEachern is unable to actually perform witchcraft!
