The station's roots date back to 1970, when CIEL's AM predecessor CJFP was authorized by the Canadian Radio-television and Telecommunications Commission to add some programming from a studio in Trois-Pistoles to the main AM signal originating in Rivière-du-Loup. However, because the AM signal failed to adequately serve Trois-Pistoles at nighttime, an FM rebroadcaster with the call sign CJTF-FM[2] was added in 1985.[3]
This transmitter was deleted from CJFP's license in 1997,[4] becoming a separate station with a license commitment to air at least 10 hours per week of distinct programming at Trois-Pistoles. The station adopted its current call sign in 2001, at the same time CJFP became CIEL-FM.[5]
