CKJD and CJFI were sold to Maclean-Hunter subsidiary Blue Water Broadcasting in 1987.

The following year, CKJD adopted a country format with the new call sign CKTY.

When Rogers acquired Maclean-Hunter in 1994, the Blue Water stations were transferred to Blackburn Radio.

On July 1, 2020 at 1:06 pm, CHKS ended its active rock format with playing "Fireworks" by The Tragically Hip repeatedly from 12:00 p.m. until 1:06 p.m.

The first song played on the new rock-oriented classic hits-based Cool 106.3 was "Electric Avenue" by Eddy Grant.
