The Canadian Radio-television and Telecommunications Commission is a public organization in Canada with mandate as a regulatory agency for broadcasting and telecommunications. It was created in 1976 when it took over responsibility for regulating telecommunication carriers. Prior to 1976, it was known as the Canadian Radio and Television Commission, which was established in 1968 by the Parliament of Canada to replace the Board of Broadcast Governors. Its headquarters is located in the Central Building of Les Terrasses de la Chaudière in Gatineau, Quebec.

Les Terrasses de la Chaudière is a complex of government office buildings in Gatineau, Quebec, Canada. The complex was built in 1978 as part of Prime Minister Pierre Trudeau's initiative to see more federal workers based in the Quebec side of the Ottawa River. It was built by developer Robert Campeau and then leased to the government. This arrangement caused some controversy as Campeau had close links to the governing Liberals. The complex was named after the nearby Chaudière Falls in the Ottawa River.
