This was a real treat to find here! As far as I knew Buffalo had gotten rid of all their Cansos many years ago.
According to Warbirdregistry.org she was delivered to the RCAF in December of 1943. In 1966 she was retired from the Air Force and went to Kenting Aircraft inToronto as CF-UAW. In 1971 Norcanair acquired it and kept it until the Province of Saskatchewan got it in 1980. It then moved to Buffalo Airways in 1992.
