History of the Squadron Post-WWII (Aircraft: Harvard II, Chipmunk, Vampire III, Silver Star, Sabre 5, Expeditor, Otter, Kiowa)

411 Squadron was reformed as an auxiliary fighter squadron at RCAF Station Downsview Ontario on 1 October 1950, and was known as the ‘County of York’ squadron. With North American Harvards and de Havilland Chipmunks as trainers the squadron operated the de Havilland Vampire III until 1956, then transitioned to the Canadair Sabre Mark V, with the Canadair Silver Star used as a trainer.

In October 1958, 411 was moved from Air Defence Command to Air Transport Command, and became a light transport squadron flying the Beech Expeditor C-45. The squadron adopted a Search and Rescue (SAR) role in spring of 1960 with the acquisition of the DHC-3 Otter. The Expeditor was retired in 1966.

On 1 February 1968 the squadron was integrated into the Canadian Armed Forces as No. 411 “County of York” Air Reserve Squadron. In 1969, 411 Squadron was transferred from Air Transport Command to 10 Tactical Air Group, and the squadron's primary role changed to the support of army operations. It continued to hold a secondary SAR role, and to do mapping surveys and sovereignty flights in the Canadian arctic. In 1981, the Otter was retired and the squadron transitioned to the CH-136 Kiowa (OH-58) helicopter, which it operated in a reconnaissance and tactical support role. The squadron finally disbanded on 1 Jan 1998.
