A 17-year-old male suffered life-threatening injuries when he was stabbed inside a Brampton highrise building on Saturday night.
Peel Regional Police say the victim was stabbed on the sixth floor or the building at 31 Fair Oaks Place.
Someone who lives in the building found the victim after he was stabbed and called police.
The victim, who does not live in the building, was taken to a Toronto trauma centre for treatment.
Sgt. Pete Brandwood said that police do not have leads yet on possible suspects or a motive for the stabbing.
