The listed crash cause is human factor. The Hydro-Québec Convair 340 (580), registration C-GFHH, serial number 109, with 18 passengers and 4 crew members on board, made an instrument flight rules flight from La Grande 3 to La Grande 4, Quebec. The aircraft touched down on the snow-covered runway at La Grande 4 approximately 800 feet beyond the runway threshold. Shortly after the nose wheel touched down and the pilot set the propellers to reverse pitch, the aircraft drifted to the right. Despite the attempts of the pilot flying (the captain) to correct, the aircraft continued its course and exited the south side of Runway 09 at approximately 50 knots. The aircraft travelled 350 feet over soft, rocky ground and came to rest about 120 feet outside the runway edge, about 2500 feet from the runway threshold. The flight crew followed the procedure to shut down the engines, but the left engine would not stop. On the captain's order, the first officer went into the passenger cabin and ordered an evacuation. All passengers exited the aircraft via the window emergency exits over the right wing. The left engine eventually shut down on its own after about 15 minutes. Five persons sustained minor injuries. The aircraft sustained substantial damage but did not catch fire.

Aircraft reference details include registration C-GFHH, MSN 109, year of manufacture 1953.
