In 1934, CFRN Edmonton signed on for the first time under those call letters. It was the first time that Dr. Dick Rice owned a radio station, despite radio experience that dated back to World War I. He had obtained funding from Coalspur grocer Hans Nielsen, the "N" in CFRN, to purchase the financially troubled CFTP from Taylor & Pearson. Taylor & Pearson had just been awarded a contract to run CJCA for the Edmonton Journal. CFTP originally signed on in 1927 as CHMA, licensed to the Christian and Missionary Alliance.
In 1975, the CBC-FM network was renamed "CBC Stereo". CBW-FM Winnipeg was the CBC's first stereo station when the CBC purchased and renamed 354,000 watt CFMW-FM, licensed to St. Norbert. CBU-FM Vancouver was the second stereo CBC station, also in 1965.
In 1998, Bryan Adams was inducted into the CAB Broadcast Hall of Fame, one day before his 39th birthday. But it would be 2006 before he was inducted into the Canadian Music Hall of Fame.
Also in 1998, CFUN and CBU Vancouver were approved by the CRTC for digital radio transmitters on 1458.048 MHz (channel 2) and 1454.560 (channel 2), respectively, both from sites in Burnaby and Mount Seymour.
