Four people are dead following the crash of an Air Sagenuay plane into a Labrador lake on Monday night.
The president of Air Saguenay confirmed the deaths on Tuesday morning, and said the fate of three more people is unclear.
The Joint Rescue Coordination Centre (JRCC) got a call at 11:30 p.m. that a Havilland DHC-2 Beaver float plane was overdue.
Seven people were on board, heading from a fishing lodge near Crossroads Lake, near the Quebec border, to a remote camp on Mistastin Lake in northern Labrador.
The group was scheduled to be back in Quebec at 6 p.m. Monday, but did not return. A Hercules airplane was put in the air as soon as the call came in to JRCC. The Hercules spotted the wreckage at 5 a.m. on Tuesday morning.
Air Saguenay has tasked a second plane to fly to Mistastin Lake to help with the search for survivors.
The cause of the crash is unknown, but officials with the Transportation Safety Board have been called in.
