The station, owned by Bell Media, airs an adult hits format branded as Bounce 104.1.

Midland-Penetang Broadcasting Ltd. opened CKMP 1230 AM on July 1, 1959, with studios at 196 Dominion Avenue in Downtown Midland.

[1] CKMP was home to many well-known announcers, including Jim Van Horne, Brian Henderson, Dan McLean and Ken Rowland.

On June 3, 1992, CKMP was given permission to rebroadcast the programming of co-owned CFOR in Orillia between 1:00 and 6:00 a.m. (with local inserts).

[10] As part of a mass format reorganization by Bell Media, on May 18, 2021, CICZ shifted to adult hits, and adopted the Bounce branding.
