This Goose was manufactured by Grumman Aircraft Engineering Corporation in 1944, as part of a U.S. Navy contract. It was acquired by the RCAF that same year and used for light transport duties. It was transferred to the Royal Canadian Mounted Police (RCMP) in 1946. Its registration, CF-MPG, apparently stands for Mounted Police Goose. When it was retired in 1994, the Goose had been in continuous public service longer than any other Canadian civil aircraft.
