George Ponsford gained his wings with the Royal Flying Corps during World War I and served as a flying instructor in Texas. After the war he worked for a number of commercial flying companies and was appointed Director of the Ontario Provincial Air Service in 1934, succeeding RoyMaxwell. In the 1930's, using purchased plans, he had Air Service engineers construct four Buhl CA-6 Air Sedans in the Sault Ste Marie hangar. The aircraft, even with several modifications, was not a great success though Ponsford redeemed himself by encouraging de Havilland to build the DHC-2 Beaver in 1947. He and his staff had much to do with the development of methods of aerial fire-fighting. Ponsford retired from the Air Service in 1960 owing to ill-health and died December, 1961.
