Four people have died and two are unaccounted for after a seaplane crash east of Tadoussac, Que., on Sunday afternoon.
The Beaver seaplane went down north of Bergeronnes in a remote wooded area not accessible by road after taking off from Bouchette Lake. Five passengers and one pilot, whose names have not yet been released, were on board.
Surete du Quebec spokesman Jean Tremblay says a search is underway for the two who are missing.
Police say they were contacted Sunday afternoon and were told the plane could not be found.
They say the wreckage was not accessible by road, and was located with the help of parachutists from the Canadian Armed Forces.
The Transportation Safety Board has sent a team of investigators to the crash site, where they will determine the best way to reach the aircraft.
Canadian Armed Forces search and rescue and Air Force personnel are aiding in the rescue and recovery efforts.
Air Saguenay did not immediately respond to requests for comment.
The airline upgraded its security system after another of its seaplanes crashed in bad weather in 2010, killing four of the six people on board.
It describes itself as an airline which provides charters for fishing, hunting and mining exploration.
