Canadian content (abbreviated CanCon, cancon, or can-con; French: contenu canadien) refers to the Canadian Radio-television and Telecommunications Commission (CRTC) requirements derived from the Broadcasting Act of Canada that radio and television broadcasters (including cable and satellite specialty channels) must comply with. These requirements dictate how much Canadian programming must be included in each broadcast episode of a program distributed by a commercial broadcaster. CanCon is part of a broader set of rules called cultural property. Cultural property includes music, movies, books, and other types of art and literature that are protected under copyright or related rights laws. Broadcasters must include a minimum amount of Canadian content in their daily schedules, which are known as periods. A period is either three hours long for radio or four for television. For example, a radio station that wants to broadcast the same program on both weekday mornings at 6 a.m. and weekend afternoons at 2 p.m. would need to provide one third (6 a.m.) Canadian content and one third U.S. content (2 p.m.). The remaining one third could be foreign language programs, educational standards programs, etc. The requirement was introduced by the government of Canada in 1970 as part of a plan to promote Canadian culture and artists. The goal was to have half of all broadcast time be Canadian content.
