The station was launched in late 1933 by young Northern Ontario media entrepreneur Roy Thomson, who would later become the owner of The Times of London. Thomson acquired the TimminsDaily Press in 1934, and the newspaper and radio station shared a building and ownership for many years. In the 1940s and 1950s, CKGB was operating on 94.5 FM as "CKRT-FM", until it was shut down. The station broadcast on AM from its inception, periodically changing frequencies until its last AM home at 750 in 1984, and adopting a country music format in 1990. Coincidentally, Thompson hired Jack Kent Cooke to be a sales rep in the hungry 1930s. He went on to own the Los Angeles Kings hockey franchise. Also in 1984, CKGB was authorized to drop its CBC Radio affiliation as network service was now available in the area from CBC-owned CBCJ-FM. In 2001, the station received CRTC approval to move to the FM dial, retaining its legendary call letters as CKGB-FM but taking on the EZ Rock brand and adult contemporary format, giving the small Timmins radio market its first direct competition, as the Haliburton Broadcasting Group-owned CHMT-FM had launched as adult contemporary/CHR hybrid Mix 93 just a few months before. Less than a year after EZRock's Timmins launch, CHMT flipped to fill the void in country radio as Moose FM. In July 2011, the station altered its musical format to present a more contemporary version of its AC Mainstream Plus blend. With this shift, the station cancelled The '80s Lunch program and Sunday at the '70sSolid GoldSaturday Night was replaced by The Saturday Night Show, a program featuring music from the 1970s to present. Scott Turnbull remains as host. The station also adopted a new logo as well as the positioning statement, "Today's Best Music". CKGB was one of four EZ Rock-branded stations owned and operated by Rogers Media, all of which are located in Northern Ontario ; as of July 2013, Rogers is in the process of rebranding all 4 stations, and is entertaining listener input through surveys on the stations' websites and through social media. On August 29, 2013, all EZ Rock stations rebranded to "Kiss", discarding the EZ Rock branding now owned by Bell Media Radio.
