The station has an ad-free news/talkformat and is part of the Première Chaîne network, which operates across Canada. Like all Première Chaîne stations, but unlike most FM stations, it broadcasts in mono.
The station signed on sometime in the late 1970s as a rebroadcaster of CBAF in Moncton. On October 3, 1983, a first radio show was produced for the Island from Moncton (La marée de l'Île, hosted by Maurice Arsenault). In 1994, it officially became a separate station, though it still has rebroadcaster-like calls.
The station has its own morning drive show, produced in Charlottetown since September 1, 1996. Denis Duchesne is the host of Le Réveil, Monday to Friday from 6 to 9 a.m. The rest of its programming is a simulcast of CBAF-FM-5 from Halifax, Nova Scotia.
On November 21, 2005, the CRTC granted CBAF-15 to operate rebroadcasters in St. Edward and Urbainville to serve areas on the fringe of the primary transmitter's signal.
CBAF-FM-15 was originally identified as CBAF-29-FM; the call sign change took effect on September 1, 1989, as the old 1300 kHz AM signal of CBAF was shut down.
