No. 6 Repair Depot was an aircraft modification and repair unit of the Royal Canadian Air Force's Air Materiel Command located at Trenton, Ontario. Duties of No. 6 RD included handling aircraft at other stations around southern Ontario and assisting with aircraft being serviced or modified at other locations such as Avro where aircraft were modified for postwar use. No. 6RD personnel ferried many aircraft types to and from Trenton, and flew aircraft to storage facilities after the Second World War. Aircraft salvage was another responsibility. Crashed aircraft or aircraft that had forced-landed were cleaned up or dismantled to be shipped back to Trenton.
