4 found dead after crashed aircraft discovered southeast of Sioux Lookout, Ont.

An aircraft has been discovered crashed in Northern Ontario after concern was expressed about its whereabouts early Saturday morning.

David Lavallee , a public affairs officer with the Canadian Air Division, part of the Royal Canadian Air Force (RCAF), told Global News that two RCAF aircraft — a CC-130H Hercules from Winnipeg-based 435 Squadron and CH-146 Griffon helicopter from 424 Squadron based at 8 Wing Trenton, Ont. — were sent to search for the missing plane “very early” in the morning.

The crash-site was southeast of Sioux Lookout and difficult to access, Lavallee said.

Joint Rescue Coordination Centre Trenton issued a tweet Saturday afternoon that said an aircraft was “reported overdue near Marathon, Ont.”

A provincial helicopter assisted with the search, alongside Civil Air Search and Rescue Thunder Bay, according to Lavallee.

“After homing in on the aircraft’s emergency locator beacon, the aircraft was found to have crashed, and tragically, there were no survivors among the four people on the aircraft,” Lavallee said.

There were four people on board the aircraft. None of them survived.

A news release from the Transportation Safety Board said a team of investigators has been deployed to the crash site.

Spokesman Chris Krepski said the plane appears to have left Dryden on Friday evening.
