Royal Canadian Air Force Detachment Alliston was opened in July 1940 near the village of Alliston, Ontario (Lots 6, 7 & 8, Concession 11, Tecumseth Twp.), this small aerodrome served as the No. 2 Relief Landing Field for No. 1 Service Flying Training School of the British Commonwealth Air Training Plan, located at RCAF Station Camp Borden. The airfield at RCAF Detachment Alliston consisted of 3 runways in a standard triangular pattern, but unlike the RCAF Detachment Edenvale, they were compressed grass runways and there were no lights for night landings. The airfield was abandoned at the end of World War II and the land was sold for farmland.
Today, not the slightest trace remains of RCAF Detachment Alliston.
