Until repealed in December 2018, per the Criminal Code, R.S.C. 1985, c. C-46: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, in the past, if you engaged in witchcraft, sorcery, fortune telling, or other similar activities, you were required to actually perform such witchcraft, sorcery, fortune telling, or other similar activities, whereas it was unlawful only to "pretends" to perform witchcraft, sorcery, fortune telling, and the like. Note that this law was applicable 365 days a year without exception, even without exception for Hallowe'en!
As an offence punishable on summary conviction procedures, the maximum fine was $5,000 and/or six months imprisonment - which leads to wondering if the six months imprisonment would be within tortuous of deathly dungeons!
Note: The above reference to 'tortuous dungeons' is satirist only!
