[1] Due to signal deficiencies on 102.1, the station was given CRTC approval to move to 107.7 FM on July 30, 2008.

[2] Since its transmitter site is located at Mount Bellevue, the station has (unlike competitors CITE-FM-1 and CIMO-FM) good coverage in the city of Sherbrooke.

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

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

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