Starting with Wardair in 1972, reusing famous registration CF-TFX, this Twin Otter has been with about all Yellowknife airline companies save Buffalo. In the Summer of 2019 though, it jumped across the continent to be employed by the Parachute School of Toronto, via ALCI Aviation and still in Summit Air livery.

This Twin Otter first flew in November 1971 and worked with Wardair Canada's northern operation from January 1972 to December 1979. Sold to Ptarmigan Airways, who continued to fly it out of Yellowknife. The airline merged with Bradley Air Services (First Air) in January 1997 and although later sold to Arctic Sunwest / Summit Air, the Twin Otter continues to be based in Yellowknife.
