Owned and operated by the (government-owned) Canadian Broadcasting Corporation, it broadcasts on 95.1 MHz from the Mount Royal candelabra tower with an effective radiated power of 100,000 watts (class C1) using an omnidirectional antenna. Its studios and master control are located at Maison Radio-Canada in Montreal.
The station has an ad-free news/talk format and is the flagship of the Ici Radio-Canada Première network which operates across Canada. Like all Première stations, but unlike most FM stations, it broadcasts in mono.
CBF went on the air on December 11, 1937, as the CBC launched its French-language network (Radio-Canada). CBF replaced CRCM, a station operated by the Canadian Radio Broadcasting Commission on 600 kHz in alternance with CFCF. CBF operated on 910 kHz using 50,000 watts full-time with an omnidirectional antenna as a clear channel (class A) station. The transmitter was located in Contrecoeur.
The station moved from 910 kHz to 690 kHz on March 29, 1941, as a result of the North American Radio Broadcasting Agreement. In 1978 the CBC consolidated its two Montréal AM broadcast transmitters and the station moved to a new transmitter site shared with CBM 940 kHz in Brossard.
CBF started to broadcast from the Maison Radio-Canada in November 1971. Commercial advertising on the station was eliminated in 1974 except for Montreal Canadiens hockey games. (CBF was the Canadiens' radio flagship since its opening in 1937 and would remain so until 1997.)
CBF applied to move to FM and was authorized to do so by the Canadian Radio-television and Telecommunications Commission (CRTC) on July 4, 1997. The AM signal covered virtually all of the western half of Quebec, and was strong enough to decently cover Ottawa and the National Capital Region as well. Indeed, until CBOF signed on in 1964, CBF doubled as the Radio-Canada outlet for Ottawa as well. Its nighttime signal covered most of the eastern half of North America, including three-fourths of Canada. However, radio frequency interference rendered it almost unlistenable in parts of Montreal during the day.
The FM transmitter was put on the air ahead of schedule on January 22, 1998, and initially had special programming targeting people affected by the 1998 Ice Storm (i.e., people without electricity). The AM signal was shut down on January 21, 1999. (For an unknown reason, English-language sister station CBM, which got permission to move to FM and started FM operations at the same time, retained its AM signal until May 14, 1999.) CBF became CBF-FM as a result of this move to FM; the existing CBF-FM station was renamed CBFX-FM. The station's old home at 690 AM was taken over by CKVL, which moved from AM 850 under the new calls of CINF. That station closed down in 2010, and the frequency remained dark until 2012, when English-language sports station CKGM moved there.
Because of severe reception problems, CBF-FM was authorized to increase its power from 17,030 watts to 100,000 watts on June 2, 2000. The power increase was implemented in mid-2001.
In recent years the popularity of the station has increased significantly. The station is now usually one of the top five stations in Bureau of Broadcast Measurement ratings (using shares), after decades of being an also-ran.

CBF-FM-10 in Sherbrooke and CBF-FM-8 in Trois-Rivières were once full satellites of CBF-FM, but have been separately licenced since 2000 (though they began airing some local programming in 1998), despite still having rebroadcaster-like callsigns. However, they are still essentially semi-satellites of CBF-FM; both repeat CBF-FM for most of the day.
On July 5, 2010, the CBC applied to decrease the effective radiated power of CBF-FM-20, Saint-Donat and also on the same date, the CBC also applied to broadcast, on the rebroadcasting transmitters CBF-16 Clova, CBF-17 Lac Edouard and CBF-18 Parent, the programming of CBF-FM-8 Trois-Rivieres instead of the programming of CBF-FM. All technical parameters of the rebroadcasting transmitters would remain unchanged.
On October 30, 2012, the CBC received approval to change the source of programming from CBF-FM to CBFG-FM Chisasibi on the following repeaters:   CBFA-FM-1 Manouane, CBFA-FM-2 Obedjiwan, CBFW-FM Wemindji, CBFM-FM Mistassini, CBFA-3 Weymontachie, CBFH-FM Waskaganish, and CBFV-FM Waswanipi.
