All 25 passengers and crew of a Canadian-operated ATR 42 have survived after the aircraft crashed outside of Fond du Lac airport in the province of Saskatchewan.

The aircraft had been en route from Fond du Lac to Stony Rapids in the far north of the province, says West Wind Aviation, the operator of the turboprop.

West Wind says there were 22 passengers and three crew members on board the aircraft.

"There are no fatalities," it states. "The extent of injuries is unknown."

Transportation Safety Board of Canada has been informed of the accident, which occurred at around 18:15 on 13 December, the carrier adds.

"At this time the cause of the accident is unknown," says the airline. "The care of passengers and crew remain the priority."

West Wind Aviation is based at Saskatoon and has a fleet of four ATR 42-300s, according to Flight Fleets Analyzer.

Images on social media purporting to show the accident site indicate that the aircraft came down in a region of woodland and was substantially damaged.

No meteorological data is immediately available from Fond du Lac airport. Stony Rapids airport, some 80km to the east, had been indicating low visibility, mist and snow in freezing temperatures.
