A 78-year-old man from Brockville, Ontario, has died following a single-vehicle collision on Highway 401 near Moulinette Road in South Stormont.
The fatal crash occurred on Thursday, November 12, 2026, at approximately 2 p.m. Stormont, Dundas and Glengarry Ontario Provincial Police (OPP) officers responded after receiving reports that a vehicle had left the westbound lanes of Highway 401 and entered a ditch.
The driver was the vehicle’s only occupant. Emergency responders transported him to a local hospital, where he was pronounced dead.
Police have not publicly released the man’s name. Investigators are working to establish the circumstances that led to the vehicle leaving the highway.
According to preliminary findings from the OPP, a medical emergency may have contributed to the collision. However, that possibility has not been confirmed, and investigators have ordered a postmortem examination to help determine the circumstances surrounding the man’s death.
The incident has prompted a renewed appeal for information from anyone who may have witnessed the crash or travelled through the area around the time it happened.
The OPP is particularly interested in receiving dashcam footage that could help investigators reconstruct the vehicle’s movements before it left the roadway.
