CIBL-FM opened in 1980 and operates under a community radio licence. It originally operated on 104,5 MHz with 16 watts from the top of one of the pyramids of Montreal's Olympic village and its target audience at that time was the Hochelaga-Maisonneuve district. Its antenna and transmitter are now located on the Olympic stadium and its signal covers the whole city since 1991. It is also known as a launch pad for several artists and radio personalities such as the late French language humor group Rock et Belles Oreilles and Télé-Québec's Marie-France Bazzo. One of its former general managers, Line Beauchamp, was a cabinet minister in Jean Charest Liberal government.
In February 2012, the station moved to a new street-level studio in the 2-22 building at the corner of Ste-Catherine and St-Laurent in the Quartier des spectacles.
