Marion Alice Orr, CM (née Powell; 25 June 1918 – 4 April 1995) was a pioneering Canadian aviator who was the first woman to run a flying school.
She served with the Air Transport Auxiliary during World War II and was awarded the Order of Canada in 1986.
[1] She then worked as an aircraft inspector at de Havilland Canada, and qualified for her commercial licence two years afterwards.
Her ATA record card in the RAF Museum shows she flew about 15 aircraft types, including the Airspeed Oxford, the only twin-engine machine.
Orr assumed the responsibility of Aero Activities Limited at Barker Field in 1947 and two years later acquired the company starting her own flying school in 1949.
She was forced to close at Barker Field because the airfield was sold for developed purpose; Aero Activities Limited was relocated to Maple, Ontario where she had to get permission from the Prime Minister Louis St. Laurent to open her own airfield, Maple Airport.
