CKGB is a Canadian radio station that broadcasts an adult contemporary format at 99.3 FM in Timmins, Ontario. The station uses the on-air brand EZRock (pronounced "E-Zee Rock", not "E-Zed Rock".)
The station is owned by Rogers Communications.
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 Timmins Daily Press in 1934, and the newspaper and radio station shared a building and ownership for many years. 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.
In 2001, the station moved to FM, retaining its legendary call letters as CKGB-FM but taking on the EZRock brand and adult contemporary format, giving the small Timmins radio market its first direct competition, as the Haliburton Broadcasting Group-owned CHMT 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.
