History
CBL-FM was launched on October 7, 1946, with the callsign VE9EV, as an FM simulcast for 740 CBL. It was the corporation's second FM station behind VE9CB in Montreal (now CBFX-FM). In 1947, its callsign was changed to CBC-FM. The station originally broadcast at 99.1 MHz, but moved to 94.1 in 1966. (The 99.1 frequency was vacant until 1977, when it was assigned to the CKO all-news radio network. CKO ceased operations in 1989, and the frequency was again vacant until it was assigned to CBLA-FM, co-owned with CBL-FM.)
As part of an 18-month trial for a nationwide FM network, CBC-FM began airing separate programming in 1960, playing mostly classical music along with the corporation's other English-language FM stations (CBM-FM Montreal and CBO-FM Ottawa). CBC-FM returned to simulcasting CBL in 1962, but resumed separate programming again in 1964. The station was renamed CBL-FM in 1968. The FM network was rebranded CBC Stereo on November 3, 1975, CBC Radio Two in 1997 and CBC Music in 2018, as it shifted away from mostly classical music, to a mix of adult album alternative, classical, jazz and other genres.

Why this record matters
The phrase “cBC Music flagship radio station in Toronto” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q5009126. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1946, 1947, 1966 and 1977.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
