The station began broadcasting in 1947 as CJIB at AM 940 kHz and went through different ownerships over the years. On March 15, 2001, CJIB was converted to the FM band at 107.5 MHz becoming Vernon's first ever FM radio station. In late 2001, CJIB adopted new call letters as CKIS which lasted until 2003, at which time it took the current callsign CKIZ, and changed formats to hot adult contemporary. CKIZ-FM reverted to AC in 2007.
The call letters CKIZ were previously used by a part-time community radio station located in Pincher Creek, Alberta, originally licensed to operate only 35 hours per week. That station operated at least through October, 1994.
