History

In 1947, CBM-FM first signed on at 100.7 MHz. In its early years, it simulcast the programming of co-owned CBM. French language CBF-FM also officially went on the air that year, at 95.1 MHz, although it had done experimental broadcasts for several years leading up to its sign-on.
In 1960, CBM-FM began airing separate programming, along with the other CBC FM stations, playing mostly classical music. It became a simulcast of CBM again in 1962, but returned to separate programming in 1964.
In 1971, CBM-FM moved to 95.1 MHz, while CBF-FM took over the 100.7 frequency vacated by CBM-FM. The exchange was made because the 100.7 frequency that was vacated had a larger coverage area and was thus deemed more suitable to serve the larger French-speaking audience. The downgrade was the result of a new bilateral arrangement with the United States for FM radio allocations. However, reception on the new frequency was poor, and as a result in July 1976 the CBC was approved by the Canadian Radio-television and Telecommunications Commission to move to 93.5 MHz. The change was made on 3 October 1977.
The CBC FM network was rebranded CBC Stereo on 3 November 1975 and CBC Radio Two in 1997. In 2006, CBM-FM and other Radio Two stations began a transition from mostly classical and jazz programming to a mix of adult album alternative, singer-songwriter and world music, as well as some classical and jazz.
The weeknight version of the jazz program Tonic, hosted by Katie Malloch, originated from CBM-FM until Malloch's retirement in 2012.
