The province's police watchdog is investigating after a man was killed in a Mississauga crash.

The Special Investigations Unit says OPP officers were conducting RIDE checks just before 6:30 a.m. on Saturday when a vehicle failed to stop for them.

The SIU says police officers tried to stop the vehicle, which hit a utility pole at Hurontario Street, north of Dundas Street.

The driver of the vehicle was pronounced dead at the scene.

The SIU says three investigators, three forensic investigators and one collision reconstruction investigator are examining the incident.

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.
