Toronto Traffic Services is investigating a crash in the city's west-end.
It happened Wednesday night, near Parkside and Bloor.
Police say they were called to the area for reports of a stolen vehicle.
There was a short chase that ended with a car smashed into the garden centre of a convenience store on Bloor.
Police say three suspects were arrested, one male is still on the loose.
One of the suspects, a female, was transported to hospital with minor injuries.
Because of that, the province's Special Investigations Unit may come in to investigate. The SIU is called in whenever police are involved in incidents where someone has been seriously hurt.
Bloor St. closed both directions at Keele as police investigate.
