On Friday, September 18, 2026, a 13-year‑old girl was reported missing after she was last seen aboard a bus traveling from Châteauguay toward Montreal. The disappearance prompted the Châteauguay police department to launch an immediate investigation and to request assistance from the public in locating the teenager.
According to police, the girl boarded the bus in Châteauguay sometime during the morning hours of September 18. She was observed on the vehicle as it headed northward toward Montreal, but she did not disembark at any of the scheduled stops along the route. After the bus completed its run, family members reported that she had not returned home, and a missing‑person report was filed later that day.
Châteauguay police have released a description of the girl and are urging anyone who may have seen her on the bus, at any of the stops, or in the surrounding neighborhoods to contact authorities. Officers are reviewing surveillance footage from the bus and from transit stations along the route to determine the exact point at which she may have left the vehicle. They have also canvassed the areas surrounding the bus stops for potential witnesses.
Investigators have not disclosed details about the ongoing search tactics, but they confirmed that resources are being allocated to the case, including patrol units and specialized teams. The police department emphasized the urgency of the situation, noting that the girl’s age makes her particularly vulnerable.
Members of the community are being asked to remain alert and to report any information, no matter how minor it may seem, to the Châteauguay police. The department has provided a dedicated phone line and an online tip form to streamline the intake of leads. Authorities reiterated that timely information could be critical to ensuring the safe return of the missing teenager.
The case remains active, and police continue to monitor all avenues of investigation while awaiting public assistance to bring the young girl home.
