CFIX is a former radio station licensed to Cornwall, Ontario to serve its francophone community. The station first took to the air on November 11, 1959 as CFML, with an effective radiated power of 10 watts. The station was a daytimer, and established a repeater in Hawkesbury as CHPR 1110 in 1976. CFML later became CFIX.
The station went silent in December 1983 due to technical and financial problems. Its owner kept the Hawkesbury rebroadcaster in service, changing its programming source to his CJLA in Lachute, Quebec and later adding some local programming.
