Many Canadians now receive their television service through some sort of multichannel television platform, such as cable, satellite and internet protocol television as opposed to an antenna-based system providing only conventional broadcast television stations. While the technical details of these platforms differ, the governing Canadian Radio-television and Telecommunications Commission (CRTC) regulations are similar for all providers.
There are two main multichannel distribution platforms in Canada. The first, and by far the largest, is cable television, the other being satellite television. Multichannel multipoint distribution services and low-power broadcast subscription channels are available in some markets.
In 1949, the Broadcast Relay Service began negotiations for the implementation of what was to be the first large scale cable television system in North America. The development of the system relied on reaching an agreement with the Quebec Hydro-Electric Commission to utilise their existing network of power poles supplying power to the Montreal metropolitan area. Initial discussions began with a meeting with the Montreal City Council on June 21, 1949. After many months of negotiation, an agreement was reached between Hydro Quebec and Rediffusion Inc. on February 28, 1950 for an initial five-year period. The Rediffusion cable system began operation in 1952, and eventually supplied 80,000 homes in Montreal, Quebec.
Cable television in Canada began in 1952 with community antenna connections in Vancouver and London; as to which city was first to launch such a service is not clear. Initially, the systems brought American stations to viewers in Canada who had no Canadian stations to watch; broadcast television, though begun late in 1952 in Toronto and Montreal, did not reach a majority of cities until 1954.
