After Astral Media (successor to Radiomutuel) bought all Telemedia Quebec radio properties in 2001, it was forced by the Competition Bureau to sell their AM stations due to concentration of ownership concerns.
Corus Entertainment, which already owned all-news station CINF (Info 690) in Montreal, promptly renamed Radiomédia as Corus Québec, and simultaneously dismantled the local CKAC newsroom, even though that newsroom was much more respected by listeners than the one from Info 690.
