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.
