Officers were called to the area of Beaverbrook Crescent and Capella Drive after receiving reports of a group of people fighting.
When they arrived, Mounties found a man lying on the street with stab wounds.
RCMP Staff Sgt. Wayne Baier says an initial investigation has found the stabbing is likely not gang-related.
He is asking any witnesses to contact Crimestoppers or the local detachment in Burnaby.
Investigators have no suspect description and no one has been arrested.
