Five people are injured, one of them critically, after a single-vehicle crash in Toronto early Monday.

Toronto police said emergency crews responded at around 1:15 a.m. to the area of Weston Road and St. Clair Avenue West.

Police said a 19-year-old man was driving a 2009 Toyota Corolla north on Weston Road when he lost control and crashed into a pole at Birdstone Crescent.

One of the passengers in the car was taken to hospital with life-threatening injuries.

The driver and three other passengers were transported to hospital with non-life-threatening injuries, police said.

There is no word on what may have led to the crash, but police said they don’t believe alcohol was a factor.

The Toronto police Traffic Services Unit is continuing to investigate.
