CKOB-FM

CKSM was not owned by Corus Entertainment as it was retained by Astral Media; it ceased to broadcast on June 30, 2007.

CHLN was authorized by the Canadian Radio-television and Telecommunications Commission (CRTC) to move to FM on November 24, 2006.

In March 2009, then-owner Corus Entertainment announced plans to drop the talk format on Corus Québec outlets CHLN, CJRC-FM in Gatineau, CHLT-FM in Sherbrooke and CKRS-FM in Saguenay in favour of a classic hits-oldies format branded as "Souvenirs Garantis", effective on March 28, 2009.

[5] On December 17, 2010, the CRTC approved the sale of most of Corus' radio stations in Quebec, including CHLN-FM, to Cogeco.

[7][8] On June 20, 2012, Cogeco announced that CKOB-FM, along with CKOF-FM and CKOY-FM, will revert to their talk formats on August 20, 2012, all but dismantling the CKOI network.
