MISSISSAUGA, Ont. -- The province's police watchdog has charged an Ontario Provincial Police officer with dangerous driving in connection with a crash near Windsor, Ont., that seriously injured a 20-year-old man.

The Special Investigations Unit says the incident occurred on Oct. 24 when an OPP cruiser collided with a civilian vehicle at an intersection in St. Joachim.

The watchdog has now charged Const. Jamie Porto, with the force's Lakeshore detachment, with dangerous driving causing bodily harm.

An agency spokeswoman refused to say whether Porto was responding to a call at the time of the crash, saying the matter is now before the courts.

Porto is due in court Jan. 22.

The SIU is an arm's length agency that investigates reports involving police where there has been death, serious injury or allegations of sexual assault.
