CKMB-FM is a Canadian radio station, broadcasting at 107.5 FM in Barrie, Ontario. The station airs music in the HOT AC format. The station was launched in 2001 by Rock 95 Broadcasting (Barrie-Orillia) Ltd., the owners of CFJB. It was launched as Star 107.5.
CKMB's call letters were taken from station owner Doug Bingley's desire to name the station after his children, Michael, Matthew and Megan Bingley. He had originally wanted to use the call letters for CFJB when that station was launched in 1988, although the call sign was not available at that time.
In December 2005, CKMB-FM rebranded from Star 107-5 to 107.5 Kool FM and forcing more current/recurrent airplay over classic airplay.
