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.

The corporate jet HS-125 aircraft departed Montreal at 2123 (GMT), 9 December 1977 with Churchill Falls as destination. The estimated time en route was 1 hour 45 minutes. The flight proceeded normally and was in contact with Air Traffic Services en route. When in range of Churchill Falls the flight received a clearance for the approach from Moncton ATC. At 2228Z the pilot acknowledged the clearance to the Churchill Falls airport and received the latest weather. The aircraft left cruising altitude shortly thereafter; the descent was normal to the minimum initial altitude for the instrument approach. The flight reported outbound to Churchill Falls advisory at approximately 2252Z. The final transmission from the crew was that they were two miles back on final with a confirmation that they could see the strobe lights and the VASIS. Moncton Centre was alerted shortly after 2300Z when it was evident that the aircraft had not landed. A local search was initiated with two helicopters from the airport but because of deteriorating weather, the search had to be discontinued and the aircraft was not found that night. Search and Rescue were alerted at 2314Z. Near blizzard conditions occurred that night and the next day, December 10. It wasn't until 11 December that the air search was resumed and the aircraft was located two miles short of the threshold of runway 14. There was no sign of life.

Flight number 621 of Air Canada DC-8-63 CF-TIW with 100 passengers, six cabin air crew and three flight crew aboard on July 5, 1970 from departure at Montreal International Airport until its final crash at Toronto International Airport lasted slightly more than 52 minutes. This aircraft took off at Montreal at 07 hours and 17 minutes EDT, initially touched down on runway 32 at Toronto International Airport at 08 hours 06 minutes and 36 seconds EDT and finally crashed at 08 hours 09 minutes 34 seconds EDT. The flight from Montreal to Toronto was routine. The flight during this interval was also routine. The "In-Range Check" was made when the aircraft was about 10 miles from Toronto International Airport on a southerly heading. The "Before-Landing Check" was made when the aircraft was about 8 miles from this Airport, and just commencing its turn onto final approach. On this Before-Landing cockpit check, which includes the lowering of the undercarriage, the item "spoilers armed" was intentionally omitted. During this period there occurred a conversation between the Captain and the First Officer as to whether the ground spoilers would be armed 'on the flare' or 'on the ground' and an agreement between them as to this was reached. The agreement was that the First Officer would arm them 'on the flare', that is, immediately before the aircraft touched down on the runway. Power was reduced then on the aircraft for the purpose of the flare and the Captain gave the order to the First Officer by saying 'OK'; and immediately thereafter the ground spoilers were deployed. The spoilers were deployed when the aircraft was about 60 feet above the runway. As a result, the aircraft sank rapidly. Practically immediately thereafter the Captain, with an exclamation, applied full throttle to all four engines and pulled back the control panel causing the nose of the aircraft to rotate upwards. During this sequence the First Officer apologized to the Captain for what he had done. Notwithstanding the action taken by the Captain, he did not succeed in preventing the aircraft from touching down on the runway. Instead, the aircraft struck the runway very heavily. It remained on the runway only about half a second and then rose back into the air at which time the ground spoilers commenced to retract and then did retract. When the aircraft struck the runway, number 4 engine and pylon separated from the aircraft and fell on the runway along with a piece of the lower wing plating (which allowed fuel to escape and subsequently ignite). Damage was also done at this time to the attachments relating to number 3 engine, but that engine after touchdown continued to function. After this touchdown, the aircraft climbed to an altitude of 3,100 feet above the ground. During this climb, there were conversations between the First Officer and the aircraft airport control tower from which it is patent, that the air crew considered that they would be able to cause their aircraft to circle for another landing attempt on runway 32. In fact, the air crew did not know, until only about 40 seconds prior to the final crash, that the happening of such final crash was irreversible. During this climb, fire and smoke were seen trailing behind the aircraft intermittently. About 2 and one half minutes after the initial touch down of this aircraft on the runway, the first explosion occurred in the right wing outboard of number 4 engine location causing parts of the outer wing structure to fall free to the ground. Six seconds later, a second explosion occurred in the vicinity of number 3 engine and the engine with its pylon ripped free of the wing and fell to the ground in flames, trailing heavy black smoke. Six and one half seconds later, a third explosion occurred which caused the loss of a large section of the right wing, including the wing tip. The aircraft then went into a violent manoeuvre, and with the right wing still ablaze, lost height rapidly and at the same time more wing plating tore free following which the aircraft struck the ground at a high velocity, about 220 knots in the attitude with the left wing high and the nose low. At final crash, all persons aboard this aircraft were killed.

Shortly after takeoff from Seven Islands Airport, while climbing, the crew reported a fire on engine number two and was cleared to return for a safe landing. After touchdown, the crew started an emergency braking procedure when control was lost due to fire in the left main gear wheel well. The airplane veered off runway to the right before coming to rest in flames. A passenger died during the evacuation and the aircraft was written off.

After passing over Chute-des-Passes, the crew encountered poor weather conditions when control was lost. The airplane crashed in unknown circumstances in the Péribonka Lake. The wreckage was found three days later. Both pilots were killed.

On final approach to Toronto-Lester Bowles Pearson Airport, while at an altitude of 700 feet 3,200 meters from the runway 28 threshold, the engine number lost power. The captain decided to shot down the engine but mistakenly stopped the engine number one. Unable to restart the engine number one, the crew increased power on both right engines number three and four but due to an asymmetric thrust, the airplane banked left then stalled and crashed short of runway threshold. All 44 occupants were evacuated safely while the aircraft was damaged beyond repair.

While flying at low height, the single engine hit trees and crashed in Longueuil, in the suburb of Montreal. The aircraft was destroyed and both occupants were injured. The airplane was owned by D. Pearson and W. Wilson.

The flight departed Montreal at 1112LT and was cleared to Burlington by the Civil Aeronautics Air Route Traffic Control to proceed In accordance with visual flight rules. A message was received from the aircraft, by the Colonial radio at Burlington, indicating that it was over the Grand Isle Fan Marker, approximately 25 miles northwest of Burlington at 1135. Colonial radio acknowledged the report and transmitted the latest local weather ceiling 800 feet, visibility 1 mile in heavy rain. This report was acknowledged. Nearing the airport, light rain was encountered. The flight asked Burlington Tower for its existing traffic, and being in the approach control area, farther asked permission to make an approach from its present position. After checking with Boston Air Route Traffic Control establishing that no traffic was in the area, the aircraft was cleared to approach VFR. The windshield wipers were turned on and simultaneously wit passing over the range station at an altitude of approximately 700 feet and sighting the airport, the tower called and stated that it had the ship in sight and that the flight was cleared to land. Flight 3 previously had been informed that the surface wind was west, variable to northwest, 5 mph, and due to a heavy rain occurring east of the airport the pilot elected to use Runway 1. The aircraft headed southwest in order to widen the pattern and establish a downwind leg at a suitable distance from the runway. During the turn to final approach the flaps and landing gear were extended, and descent was made toward the airport aligned with Runway 01. The aircraft landed long and was unable to stop within the remaining runway, overran and came to rest in trees. All 17 occupants escaped slightly injured while the aircraft was damaged beyond repair.
