In 1937, CFGP Grande Prairie signed on at 7:30 p.m. with a Remote from Speke Hall, where the official opening ceremonies were taking place. The station was on 1200 KHz with 100 watts. A lot of frequency changes followed: 1310 in 1940; 1340 in 1941; 1350 in 1944; 1050 in 1946; and to FM on 97.7 MHz in 1996.

In 1987, CFCR-FM Red Deer became CIZZ-FM at 9:00 a.m., switching from its money-losing country music format, to Rock. In late August, Shaw (later known as Corus) had acquired the station, and Country-formatted CKGY-AM, from Park Country Broadcasting, which had just bought CFCR from Central Alberta Broadcasting.

In 1994, the CRTC revoked (at owner request) the licenses of Quebec AM stations CJMS Montreal, CJRP Quebec City, CJMT Chicoutimi, CJRS Sherbrooke, CJTR Trois-Rivieres and CKCH Hull following the merger of Telemedia and Radiomutuel, who each owned an AM station in those markets. They retained their FM stations.
