The House of Commons Broadcast Service was set up in October 1977 to be responsible to maintain the video and audio equipment. It was CBC's responsibility to take that signal and transmit it to the Anik satellite to be received by Canadian cable companies.
For most of the network's history, John Warren hosted a preview monologue before the beginning of and provided a short summary after the daily proceedings.
In 1986, it was used to air CBC's The National and The Journal at 10 p.m. Eastern when it was pre-empted on the main CBC network by the NHL hockey playoffs. This prompted complaints from the cable services and the CBC's privately owned affiliates and the network was rebuked by the CRTC for not having first asked for the authorization from the CRTC. Commission chairman Andre Bureau commented "We're not against the CBC using the parliamentary channel for special events if they are authorized to do so by the CRTC, but they should respect the regulations and come to us first." The experiment was not repeated.
For a while during the 1980s, CBC suggested that its broadcast day could be expanded into a second CBC network, CBC-2. However when they applied to the CRTC for this network, they denied it for that purpose.
