A 20-year-old man is facing a second-degree murder charge after his father was stabbed to death in Etobicoke.

The stabbing happened on Redgrave Drive, near Martin Grove Road and Eglinton Avenue West, around 4:30 p.m. on Tuesday.

Police say the two men were involved in an altercation when the father was stabbed. He was pronounced dead at the scene.

He has been identified as 50-year-old Ameer Saib of Toronto.

A woman, who police say is the suspect’s mother, attempted to intervene and suffered minor injuries. She was assessed at the scene and was not taken to hospital.

The suspect, identified as Noah Saib, fled the scene and was involved in a single-vehicle crash near Highway 401 and Islington Avenue. He was rushed to hospital with serious stab wounds, and has since been arrested.

All eastbound collector lanes of the 401 were closed between Dixon Road and Islington during rush hour.
