CBL-FM is the flagship station of the CBC Radio 2 network, based in Toronto, Ontario, Canada. It broadcasts at 94.1 on the FM dial, and also serves Huntsville (FM 106.9), Orillia (FM 90.7), Peterborough (FM 103.9) and other locations in Ontario.
CBL's studios are located at the Canadian Broadcasting Centre, while its transmitter is located atop the CN Tower.
CBL-FM was launched in 1946, simulcasting CBL-AM on the FM band. It originally broadcast at 99.1, but moved to 94.1 in 1966. (The 99.1 frequency was vacant until 1977, when it was assigned to the CKO radio network. CKO ceased operations in 1989, and the frequency was again vacant until it was assigned to CBLA.)
It began airing separate programming in 1960, along with the other CBC FM stations, in 1960. It became a simulcast of CBL again in 1962, but broke off again in 1964. The FM network was rebranded CBC Stereo on November 3, 1975, and CBC Radio Two in 1997.
