The Transportation Safety Board of Canada is investigating a plane crash that killed four people in northwestern Ontario on Friday. David Lavallee, public relations officer at the Royal Canadian Air Force, says the search for the Piper PA-28 Cherokee began near Sioux Lookout, OD, at about 4:30 a.m. Saturday after officials were notified of a delayed aircraft . He says rescuers were able to enter the house with the aircraft’s emergency response transponder and the crash site was discovered later that day in a remote area southeast of Sioux Lookout, about 450 miles (450 km) east of Winnipeg. Lavallee says four people were on the plane and no one survived the crash. The extensive search included a Hercules turbocharged aircraft and a Griffon helicopter from the Air Force, as well as an Ontario government helicopter and a team from the Civil Aviation Search and Rescue Association of Thunder Bay, Ont. A statement from the Transport Safety Council said a team of investigators had been deployed to the crash site. This Canadian Press report was first published on May 1, 2022.
