The station launched in 1978 playing "oldies" from offices and studios just north of Edmonton in St. Albert. The original frequency was 1070 kHz with the callsign CKST. In 1988, CKST received approval to move from to 1200 AM and changed callsigns to CHMG the same year. CHMG received approval move from AM to FM in 1994. In 1995, CHMG changed to its current callsign, CFMG. At the same time, the station shifted to an adult contemporary format, branded as EZ Rock. Programmed by longtime broadcaster Tammy Cole, EZ Rock was a station designed to appeal tooffice work environments. Music was slanted towards female listeners 25–54 years old. On September 28, 2007, the CRTC approved the sale of CFMG and all Standard Radio assets to Astral Media. Astral changed the logo of the station in September 2010; however, the adult contemporary format is unchanged while continuing to say the decimal point on the station ID. In addition, most of the classic hits were dropped.
104.9 Virgin Radio
On February 4, 2011, the station dropped adult contemporary and flipped to Top 40/CHR as 104.9 Virgin Radio. EZ Rock's last song was The Boys Of Summer by Don Henley, while the first song on "Virgin" was "Firework" by Katy Perry. This left Edmonton with no adult contemporary station for 51 days until CKEA-FM dropped adult album alternative for adult contemporary. CFMG, during its final adult contemporary week, did list its contemporary hit radio adds on Mediabase's Canadian adult contemporary panel. A week after the station flipped formats, the station was delisted from Mediabase's station adds. As of March 2011, CFMG-FM joined CHBN-FM on the Mediabase contemporary hit radio panel. CFMG is the third Virgin Radio station in Canada to have a mainstream top 40 format, the first being at Calgary's CIBK-FMthe year before, and in Toronto at CKFM-FM in 2009. Every year for one week, along with sister stationsCFBR-FM and CFRN, CFMG-FM presents, Stollery Week, a week long fundraiser for the Stollery Children's Hospital. In past years all three stations had broadcast live for 2 days from the Stollery Children's Hospital. In year one, $300,000 was raised for the Pediatric Oncology Unit; in year two, EZ Rock and her sister stations raised $500,000 for Research.
