6 Repair Depot (6 RD) was an aircraft modification and repair unit of the Royal Canadian Air Force's Air Materiel Command located at Trenton, Ontario.
Nicknamed "tent city", the mechanics had to sleep there for many weeks in a row.
During New Year's Eve of 1952, fireworks set fire to hangar No.
9 and it burned to the ground along with three Lancasters, two Mitchells, one Grumman Goose, a Harvard and numerous pieces of handling equipment.
6RD specialized in the repair of North American Harvard trainers as well as Avro Ansons, Liberators and Spitfires for the RCAF and the RAF in 1940 until after the Second World War.
