CBCS-FM
radio station (99.9 FM) licensed to Sudbury, Ontario, Canada
CBCS-FM is a Canadian radio station. It is the CBC Radio One station in Sudbury, Ontario, broadcasting at 99.9 FM, and serves all of Northeastern Ontario through its network of relay transmitters. The station's studio is located at the CBC/Radio-Canada facilities at 43 Elm Street in Sudbury.
History
On July 28, 1975, the Canadian Broadcasting Corporation received approval from the CRTC to operate a new English-language FM station at Sudbury, Ontario. The proposed frequency was 97.1 MHz (later read 99.9 MHz when launched).
The station was launched on May 5, 1978 on 99.9 MHz. Prior to its launch, CBC Radio programming aired on private affiliates CKSO and CKSO-FM.
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.

Why this record matters
The subject matters to the places & architecture register because the source frames it as radio station (99.9 FM) licensed to Sudbury, Ontario, Canada. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 25, 2026. The linked authority identifier is Q5008993. Authority coordinates are 46.504, -80.968. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1975, 1978, 1984 and 1991.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
