As early as 1970, Université de Montréal students developed the idea of a French college radio station. In 1980, a requested feasibility study gave place to recommendations for a potential radio broadcasting school. At noon on October 7, 1985, CISM broadcast its first radio show over the university's campus. In July 1990, CISM gained its FM broadcast permit from the Canadian Radio-television and Telecommunications Commission (CRTC).[1] Then, on March 14, 1991, CISM's broadcasting antenna (located atop Mount Royal) was boosted to 10,000 watts. With a broadcasting radius of 70 km, CISM is now the world's largest French-language college radio station.

The station also broadcasts a Tamil language radio format on a subsidiary communications multiplex operation frequency, branded as International Tamil Radio (ITR-FM). ITR-FM has recently been granted approval for a 50-watt station on FM 102.9 in the Ahuntsic neighbourhood.[2]
