CFIN-FM is a defunct radio station in Coaticook, Quebec Canada. In 1982, Coaticook FM Inc.'s application for a new FM station was denied. The station reapplied the same year to broadcast at 104.5 MHz (FM) with power of 710 watts and received CRTC approval in November 1982. The CFIN callsign was assigned in February 1983 and signed on in October later that same year. CFIN received approval to decrease power from 710 to 450 watts in 1984. In 1986, the station received a short-term one year licence renewal. The commission denied the renewal application a year later.
