CBC Symphony Orchestra

The CBC Symphony Orchestra (CBCSO) was a Canadian orchestra based in Toronto, Ontario that was operated by the Canadian Broadcasting Corporation during the 1950s and 1960s. Founded in 1952, conductor Geoffrey Waddington served as the orchestra'a only music director; although other conductors, such as Jean-Marie Beaudet, had strong ties with the orchestra. The CBCSO consisted of 80 instrumenalists of which approximately half were also members of the Toronto Symphony Orchestra. Violinist Albert Pratz was notably concertmaster of the orchestra from 1953-1961.

The CBCSO played weekly broadcasts on CBC Radio and also made frequent appearances on CBC Television. It gave its first broadcast on 29 September 1952 performing Jean Sibelius's Symphony No. 3 and the overture to Gioachino Rossini's opera La Cenerentola. The orchestra disbanded in 1964.
