The combined effect of Sections 197 to 206 of the Canadian Criminal Code bans for-profit gaming or betting, with exceptions made for provincial lotteries, licensed casinos, and charity events. Many stores, radio stations, and other groups still wish to hold contests to encourage more purchases or increase consumer interest. These organizations take advantage of the fact that the law does allow prizes to be given for games of skill, or mixed games of skill and chance. To make the chance-based contests legal, such games generally consist of a mathematical skill-testing question (STQ). Penalties for violating the contest section of the Criminal Code, if it was enforced, include up to two years of imprisonment if charged as an indictable offense or a fine no more than $25,000 on a summary conviction charge.
