The station was launched in 1949 by a local non-profit consortium to bring French radio service to Edmonton, and was directly acquired by the network in 1974.
The station serves the entire province of Alberta from its studios in Edmonton, although it also maintains a smaller bureau in Calgary.
For most of its history, the station broadcast at 680 on the AM band. On January 20, 2012, it was announced that Radio-Canada planned to close down CHFA's AM transmitter at 680, with its nested FM repeater in Edmonton, CHFA-10-FM at 101.1 MHz, swapping places with the much-stronger Espace musique station CBCX-FM-1 at 90.1 MHz. This application was approved by the Canadian Radio-television and Telecommunications Commission on June 22, 2012.
The station's current local programs are Le café show, in the mornings from 6:00 a.m. to 9 a.m., Le midi 30 from 12:30 p.m. to 1 p.m. and La croisée in the afternoons, 4 p.m. to 6 p.m. The Saturday morning program, Les samedis du monde, originates from CKSB-10-FMWinnipeg is heard tape delayed from 7:00 a.m. to 11 a.m. On holidays, its local programs are replaced with special pan-regional programming from CKSB-10-FM: Les matins de l'Ouest, Les midis de l'Ouest and Sors de la boîte, all taped delayed from earlier.
