The Kitchener–Waterloo Symphony (KWS) is an orchestra based in the twin cities of Kitchener and Waterloo, Ontario, Canada. Its home venue is located at Centre In The Square in Kitchener, Ontario. The orchestra consists of 52 professional musicians under full-time contract. KWS performs close to 90 performances during a 38-week season for a combined concert audience of over 90,000. The orchestra is regularly heard across Canada on CBC Radio Two. In September 2023, the symphony abruptly halted its 2023–2024 season, citing its financial difficulties, and later declared bankruptcy. This included all concerts and other activities such as, Kitchener–Waterloo Symphony Youth Orchestra and Bridge to Music. As of late October 2024, the orchestra announced that the bankruptcy had been annulled and that they are rebuilding with a new Board of Directors.
