Call signs in Canada

Call signs in Canada are three, four or five letters long (not including the "–FM", "TV" or "–DT" suffix) and are assigned to a variety of broadcasters. Call signs are regulated internationally by the ITU as well as nationally by Industry Canada, which regulates all aspects of amateur radio in the country. It assigns call signs, issues amateur radio licences, conducts exams, allots frequency spectrum, and monitors the radio waves.

Call signs generally begin with "CB", "CF", "CH", "CI", "CJ", "CK", "VA"–"VG", "VO", "VX", "VY", or "XJ"–"XO". The "CB" series calls are assigned to Chile by the ITU, but Canada makes de facto use of this series anyway for stations belonging to, but not exclusively broadcasting programs from, the Canadian Broadcasting Corporation (CBC). Several other prefixes, including "CG", "CY", "CZ" and the "XJ" to "XO" range, are available. Conventional radio and television stations almost exclusively use "C" call signs; with a few exceptions noted below, the "V" codes are restricted to specialized uses such as amateur radio.

Special broadcast undertakings such as Internet radio, cable FM, carrier current or closed circuit stations may sometimes be known by unofficial call signs such as "CSCR". These are not governed by the Canadian media regulation system, and may at times reflect call signs that would not be permissible on a conventional broadcast platform.

The International Telecommunication Union has assigned Canada the following call sign blocks for all radio communication, broadcasting or transmission:

While not directly related to call signs, the International Telecommunication Union (ITU) has further divided all countries assigned amateur radio prefixes into three regions; Canada is located in ITU Region 2.
