Saint-Charles-sur-Richelieu, Québec – Two people have died following a single-vehicle crash in Saint-Charles-sur-Richelieu, Québec, on Sunday, September 13, 2026.
The collision happened at approximately 4 p.m. on chemin des Patriotes, also known as Route 133 or Patriotes Road, near Meunier Street in the Montérégie region.
According to preliminary information, a vehicle travelling along the road lost control, left the roadway and struck a tree. The crash prompted an emergency response, with authorities attending the scene to assist those involved and begin investigating the circumstances.
The driver, a woman in her 40s, was seriously injured in the collision. She was transported to a hospital for medical treatment but later died from her injuries.
A minor who was travelling as a passenger in the vehicle was pronounced dead at the scene.
The Sûreté du Québec (SQ) is investigating the crash. At the time of the latest available information, authorities had not publicly established what caused the vehicle to leave the roadway. Factors such as speed, weather, road conditions or driver-related circumstances had not been confirmed.
Investigators are expected to examine the crash scene and available evidence as they work to determine the sequence of events leading to the fatal collision. Until the investigation establishes the cause, speculation about contributing factors should be avoided.
The fatal crash occurred on the same afternoon as another serious collision in the wider area. Approximately 30 minutes earlier, a separate two-vehicle crash in nearby Saint-Rémi sent two people to hospital, with one reported to be in critical condition. The incidents are not reported to be connected.
Saint-Charles-sur-Richelieu has experienced other serious road collisions in previous years, including fatal crashes on chemin des Patriotes. Those earlier incidents provide historical context for road safety in the municipality, though they do not establish the cause of the September 13 collision.
The identities of the woman and minor killed in Sunday’s crash had not been publicly released in the information available for this report.
The SQ investigation remains ongoing. Further information about the victims, the circumstances of the crash and any findings from investigators may be released as authorities continue their work.
For families and residents of Saint-Charles-sur-Richelieu, the deaths mark another devastating road tragedy in the Montérégie community. Any confirmed updates should be based on statements from police, the Coroner or the victims’ relatives.
