CJBC (860 kHz) is a French language, non-commercial, public radio station in Toronto, Ontario.

A previous radio station with the call sign CJBC was owned and operated by the Jarvis Street Baptist Church from 1925 until 1933.

The CJBC call letters were subsequently acquired by the Canadian Broadcasting Corporation to replace CBY.

CJBC began carrying some French language programming in 1962, initially in the form of a nightly, half-hour newscast.

With the closure of the Dominion Network on October 1, 1962, CJBC's French schedule expanded to two hours of programming each evening.

The station maintained a skeleton staff of just two reporters for local news breaks, while otherwise simulcasting CJBC's programming the rest of the time.

Since 1993, the CJBC studios have been based at the Canadian Broadcasting Centre on Front Street West in Downtown Toronto.

In 2011, following the revocation of CKLN-FM's licence, the CBC submitted an unsuccessful application to the CRTC to add a nested rebroadcaster of CJBC on 88.1 FM in Toronto.
