Taken by Margaret Olafson. This aircraft came to Canada new in 1971 and has been operating in Canada's North ever since. The one on the left is likely C-FYDU which is no longer on the Canadian registry.
This 1970 Islander worked in the USA and Puerto Rico until 1978 when Air North bought it. After an accident in 1986, the aircraft was sold to Rocky Mountain Aircraft for parts and the registration cancelled.
