CBL-FM is the flagship station of the CBC Music network. It is a non-commercial station, licensed to Toronto, Ontario, and is owned by the Canadian Broadcasting Corporation.

History

CBL-FM was launched on October 7, 1946, with the callsign VE9EV, as an FM simulcast for 740 CBL. It was the corporation's second FM station behind VE9CB in Montreal. In 1947, its callsign was changed to CBC-FM. The station originally broadcast at 99.1 MHz, but moved to 94.1 in 1966.
As part of an 18-month trial for a nationwide FM network, CBC-FM began airing separate programming in 1960, playing mostly classical music along with the corporation's other English-language FM stations. CBC-FM returned to simulcasting CBL in 1962, but resumed separate programming again in 1964. The station was renamed CBL-FM in 1968. The FM network was rebranded CBC Stereo on November 3, 1975, CBC Radio Two in 1997 and CBC Music in 2018, as it shifted away from mostly classical music, to a mix of adult album alternative, classical, jazz and other genres.

Rebroadcasters

On February 15, 1979, the CRTC approved the CBC's application to operate a new FM transmitter in Belleville on 94.3 MHz and on May 7, 1979, the CRTC also approved the CBC's application to operate a new FM transmitter in Brockville on 104.9 MHz, to rebroadcast the programming originating from CBL-FM Toronto. Neither of these transmitters in Belleville and Brockville were implemented and the frequencies were awarded to other broadcasters.
In 1979, CBBK-FM began broadcasting at 92.9 MHz in Kingston.
In 1983, a rebroadcaster was added at Peterborough operating at 103.9 MHz as CBBP-FM.
On June 28, 2005, the CRTC approved the CBC's application to change the frequency of its transmitter CBL-FM-1 104.7 to 106.9 MHz. This change of frequency was to eliminate significant interference with a local radio station CFBK-FM operating at 105.5 MHz in Huntsville.
