A man was arrested on suspicion of impaired driving following a three-vehicle collision downtown that sent one person to hospital with serious injuries.

Police responded to the area of Jarvis St. and Carlton St. just before 7 a.m. following a report that a vehicle had run a red light and caused a collision. Three vehicles were involved, and the streets were closed for several hours. Paramedics say a female in her teens was taken to hospital in serious condition, with what police described as an upper body injury. No one else was taken to hospital.

The streets were closed for the investigation, but have since been reopened. It is not yet known whether charges will be laid.
