The CRTC decision authorizing the launch of CBCS in fact encouraged, but did not direct, the CBC to retain an AM frequency for CBC Radio, and to reserve CBCS for its CBC Stereo network. However, the station launched in 1978 as an affiliate of the talk network after the CBC was unable to negotiate an agreement with Cambrian Broadcasting to directly acquire CKSO.
The CBC later applied for a second license for its Stereo network, which was granted in 1984. However, that station remain unlaunched throughout the 1980s, and the CBC was forced in 1991 to surrender all of its non-operating licenses. Consequently, CBC Radio 2 service was not available in the city until the launch of CBBS-FM in 2001.
In the CBC's service reductions announced in March 2009, CBCS was slated to lose half of its existing staff. Several hundred people attended a rally at the city's Tom Davies Square on April 5 to protest the cutbacks, with participants including federal MPs Glenn Thibeault, Claude Gravelle and Charlie Angus, and musicians Kevin Closs and Stéphane Paquette.
The station's local programs are Morning North, hosted by Markus Schwabe, in the morning and Points North, hosted by Jason Turnbull, in the afternoon. In May 2009, Morning North won the Radio and Television News Directors Association's Peter Gzowski Award for Best Information Radio Program in Central Canada, and in June 2009, the program won the award for all of Canada.
Former Points North host Dan Lessard retired from the program in June 2010.
In the CBC's proposed new regional programming strategy released in 2005, North Bay is scheduled to receive its own local news bureau, although North Bay would continue to receive CBCS' local programming apart from news updates.
