Police in Châteauguay are urging anyone with information to come forward after a 13‑year‑old girl vanished on a bus traveling toward Montreal on Friday, September 18, 2026. The disappearance prompted an immediate response from the local police force, which has since broadened the effort to include provincial authorities.

The teenager was last observed aboard a public transit vehicle departing Châteauguay for Montreal. After the bus left the municipality, she could not be located, and her absence was reported to officers later that day. Since that initial report, Châteauguay police have been conducting a systematic search of the area, checking bus routes, stations and nearby neighborhoods for any sign of the missing child.

Quebec police have joined the investigation, providing additional resources and expertise to assist the local team. Together, the agencies are canvassing the bus route, reviewing surveillance footage, and speaking with passengers who may have been on the vehicle at the time of the incident. Both police services have emphasized that any detail, no matter how small, could prove critical in locating the girl.

Authorities have asked the public to remain alert and report any sightings or information that could relate to the case. They have also reminded residents that the search is ongoing and that the safety of the child remains the top priority. Police have set up a dedicated line for tips and are prepared to follow up on every lead received.

The community response has been swift, with local volunteers offering assistance and neighbors expressing concern for the missing teenager. As the investigation continues, police maintain that they will keep the public informed of any developments and remain committed to bringing the girl home safely.
