CJLM-FM is a French-language Canadian radio station located in Joliette, Quebec, about 40 kilometres northeast of Montreal. The station has an adult contemporary music format and identifies itself as "M 103,5 FM". It broadcasts on 103.5 MHz with an effective radiated power of 3,000 watts (class A) using an omnidirectional antenna.
Since 1997, CJLM-FM is owned and operated by the "Coopérative de radiodiffusion MF 103,5 de Lanaudière", a cooperative that was created to buy the station after the bankruptcy of the previous owner.
CJLM (as it was originally known) opened in April 1960 as an AM station on 1350 kHz, and moved to FM in 1996.
In 2013, Attraction Radio announced plans to acquire CJLM-FM from the cooperative; the decision is currently awaiting CRTC approval.
