A 26-year-old man is in critical condition in hospital after he was shot in Vaughan, the third shooting in the GTA in 12 hours.
A 23-year-old woman was assaulted in the same incident. She was taken to hospital and has since been released.
York police say two men approached the pair in a plaza at 100 Steeles Ave. W, near Yonge Street, around 11 p.m. on Monday.
The men demanded the keys to their car, a black 2008 Ford Focus. Police say they then shot the man, assaulted the woman, and stole their car. The car has the license plate BNNM866.
