The station was originally launched in Iroquois Falls in 1922, as CFCH, a corporate communications service for lumber camps owned by Abitibi Power and Paper Company.
In 1960, Thomson's Northern Broadcasting acquired the city's television station, CKGN, which also adopted the CFCH callsign.
CFCH was an affiliate of the Canadian Broadcasting Corporation's Trans-Canada Network and then of CBC Radio, until 1976 when CBCN-FM launched.
On August 16, 1996, Telemedia swapped the stations in a move similar to its 1990 switch involving CKSO and CIGM in Sudbury.
The heritage CFCH call sign returned in North Bay at a radio station (as CFCH-FM) that was launched by Vista Broadcast Group at 90.5 FM on June 15, 2021).
