In 1943, George Duffield began a nearly 40 year radio career, during which he only had one boss: Dick Rice. Until the latter years, even the call letters stayed the same. In 1972, he moved from Edmonton's CFRN-AM to CFRN-FM, whose call letters had changed to CKXM by the time Duffield retired on January 31, 1982. But George had no qualms about new technology, being part of the station's first FM demonstration at the 1946 CAB Convention in Jasper Park Lodge. He passed away in April 2004 at 87.
In 1973, the CRTC issued a policy proposal on FM radio, seeking Public and Industry input for the remainder of that year on how FM should differ from AM radio in Canada.
In 2002, Standard Radio received CRTC approval to acquire 64 radio stations and 2 television stations in Ontario, Alberta and British Columbia from Telemedia, and immediately resell some of the medium and small market stations to Rogers and NewCap. Standard did not resell use of the EZ Rock (pronounced as in the U.S. "Eee-Zee Rock") name that it obtained from Telemedia, so Rogers and NewCap found themselves re-branding some of automated Adult Contemporary stations to things like Lite-FM.
Meanwhile, in Quebec, the Competition Commissioner was overruled by the CRTC after Astral agreed to sell CFOM-FM, and was allowed to purchase all of Telemedia's Quebec radio stations.
