CBBS-FM is a Canadian radio station, which broadcasts the Canadian Broadcasting Corporation's CBC Music network on 90.1 FM in Sudbury, Ontario. The station was originally licensed by the CRTC in 1984. However, due to financial constraints at the CBC, the station was never launched, and the CBC was forced in 1991 to surrender all of its non-operating licenses. The license surrender left Sudbury as one of the largest cities in all of Canada not served by the CBC's music network.
