The station operates under a community radio licence and offers varied programming in seven different languages whereas all programmes are produced and animated by volunteers. It identifies itself as "Radio Centre-Ville".
CINQ-FM opened on 27 January 1975; at the time the station was on 99.3 MHz and used only 7.5 watts of power. Originally, the station aired programming in five different languages, hence the call sign ("cinq" being the French word for "five"). Those five languages were English, French, Spanish, Portuguese, and Greek. It has since added Creole and Chinese (Mandarin and Cantonese) programming to its lineup.
