The Châteauguay police department is asking for the public’s help in locating a 13-year-old girl.

Châteauguay resident Mia Bertrand was last seen in the South Shore suburb on Friday, on a bus headed toward Angrignon. Police say her family and friends have reason to fear for her health and safety.

Mia speaks French. She stands 5 foot 5 (1.58 m), weighs 110 pounds (50 kg) and has brown hair and brown eyes.
