The military police says it found no evidence that assets were misused when the CH-146 Griffon flew to No Name Lake on June 8, 2012.
Members of 5 Wing Goose Bay came under criticism after a provincial politician posted a photo on Facebook showing crew members fishing during the trip.
At the time, the airbase said the trip was meant to recognize the effort of ground crews in finishing maintenance and inspection of an aircraft that returned from a deployment in Jamaica.
A spokesman for 5 Wing Goose Bay also said at the time that crew members conducted a reconnaissance mission and survival training in the area of No Name Lake, including fishing.
The Canadian Forces National Investigation Service, the military police's investigative wing, says the chopper was used for local training and to clear brush from a landing pad, and not as survival training as the air force originally reported.
