In Canada, there are rules for advertising to children. Except in Quebec, where all advertising to children under the age of 13 is prohibited under the Quebec Consumer Protection Act, advertisements in broadcast media directed at children under 12 years of age must follow a set of voluntary guidelines called the Broadcast Code for Advertising to Children. The Code does not pertain to ads broadcast on U.S channels. Compliance with the Code is a condition of licence for Canadian broadcasters.
