No. 3 (Bomber) Squadron was a Royal Canadian Air Force (RCAF) squadron active during the late 1930s. Formed in 1935 with bomber and fighter flights, the squadron took two years to receive its bomber aircraft, after which the fighter flight was expanded into a separate squadron. After the outbreak of World War II it moved to Halifax to provide anti-ship capability, but was redesignated as a fighter squadron while in transit. The squadron never actually became the latter and was disbanded within days of its move to Halifax, with its aircraft and personnel being transferred to a new bomber squadron.
