She was last seen walking west on Helen Avenue toward Kennedy.
York Regional Police Const. Andy Pattenden said it’s out of character for her to go missing.
“It’s very odd for her to have not been in contact with friends and family … and we are concerned for her well-being.”
Luong is described as Asian, five feet five inches tall and 100 pounds.
She has short black hair with bangs and was last seen wearing a long purple winter coat.
