summer season or when a regularly scheduled program is preempted due to a statutory holiday. Former affiliates While all CBC Radio stations today are owned and operated by the network there previously were a number of privately owned network affiliates of what is now CBC Radio One and its predecessors, the Trans-Canada Network, and the original CBC Radio network. Some were affiliates of the original CBC radio network prior to 1944, several of which had previously been affiliates of the CBC's predecessor, the Canadian Radio Broadcasting Commission. Some were affiliates of the Trans-Canada Network (1944-1962) and either disaffiliated from TCN or became CBC Radio affiliates when TCN became CBC Radio in 1962. Some transferred their affiliation to CBC Radio when the Dominion Network dissolved in 1962. Most affiliates disaffiliated as the CBC built new owned and operated stations, expanded coverage by other stations, or built transmitters to rebroadcast existing CBC Radio stations. Other affiliates were purchased from their owners by the CBC and are listed under CBC Radio One stations above or at List of defunct CBC radio transmitters in Canada if they are no longer operating.
