Police in Châteauguay, in coordination with Quebec provincial authorities, have launched an appeal for public assistance in locating a 13‑year‑old girl who disappeared on Friday, September 18, 2026. The child was last seen while traveling on a bus that departed from Châteauguay and was headed toward Montreal. No further details about the bus route or the circumstances of her disappearance have been released.

Authorities confirmed that the search began shortly after the girl was reported missing. Both municipal and provincial police units are conducting inquiries and have asked anyone who may have been on the bus, or who observed unusual activity along the route, to come forward. Officers emphasized that any piece of information, no matter how minor it may seem, could be valuable to the investigation.

The police bulletin stated that the girl is 13 years old, and that her disappearance is being treated with urgency. While the exact time of her last sighting has not been disclosed, the incident occurred on the same day the bus left Châteauguay for Montreal. The joint effort reflects the standard protocol for missing‑person cases involving minors, with local officers handling immediate response and Quebec police providing additional resources.

Members of the public are encouraged to contact the Châteauguay police department directly if they have any recollection of the bus ride, the girl’s appearance, or any other relevant observations. The police have assured that tips can be submitted anonymously. The investigation remains active, and authorities have reiterated the importance of community cooperation in resolving the case.

No further updates have been provided at this time, and the search continues as police maintain a presence in the area. The family of the missing child has not been quoted publicly, and no statements from them have been released.
