On November 15, 2025, two aircraft crashed into each other in Ontario, Canada, a Cessna 172, and a Piper Seminole. A 28-year-old man from Montreal was declared dead at the scene.
The Crash in Ontario
The incident occurred on Saturday morning at around 10:50 am according to a spokesperson for the Transportation Safety Board (TSB).
Ontario Provincial Police received a call from a witness according to Const. Serge Duguay and the sole occupant of the Cessna 172 was pronounced dead after crashing in a forest north of Martintown, South Glengarry. The other aircraft, the Piper Seminole, was carrying two people who were left unharmed and landed safely at the Cornwall-Summerstown Regional Airport.
Local resident Glen Finbow recounted his sighting of the crash, hearing a loud “pop” before seeing a plane rapidly descend towards the ground with only one wing intact.
He immediately called 911, and has said:
The plane was probably, I would think 2,000 feet up. And all you could see was [it going] straight down, … Didn’t turn, didn’t spin, didn’t do anything. Just straight down.
Training Exercise Gone Wrong
Both planes were owned by Cornwall Aviation and were in the middle of separate training exercises when they collided in the air. It is suspected that the crash may have severed one of the Cessna 172’s wings, causing it to descend in such a way that it did.
Senior TSB Investigator, J.P. Regnier has said that the TSB is unsure as to how the two aircraft came in contact with each other. However, an investigation is underway, with authorities recovering the wreckage from the forest and investigators remaining on site for several days working to determine how the collision occurred.
This tragic incident that hit Canadian aviation over the weekend is a saddening event and our thoughts are with those affected. As the investigation continues we will provide updates with any further progression.
