Owned and operated by RNC Media, it broadcasts on 104.9 MHz using an omnidirectional antenna with an effective radiated power of 3,000 watts (class A). The station airs an oldies format branded as Lov' Radio. Part of CJLA-FM's programming is simulcast on co-owned CHPR-FM in neighbouring Hawkesbury, Ontario.
The station was launched in 1974 on AM 630 kHz by Radio Lachute, and was acquired by Guy Vaillancourt in 1980. Vaillancourt subsequently acquired CFIX in Cornwall, Ontario in 1983, and shut that station down but retained its rebroadcaster CHPR in Hawkesbury as a rebroadcaster of CJLA.
The station moved to the FM band in February 1986, being one of the very first AM stations permitted to do in Canada. As an AM station, CJLA was one of the few stations authorized to increase its power at night, from 500 watts to 1,000 watts. The station switched its call sign from CJLA-FM to CJGO-FM in 2000, but quickly reverted to CJLA-FM the following year; the reason for these changes is unknown.
