Ontario's police watchdog is investigating after a man fell to his death in a No Frills parking lot in Newmarket.
The S-I-U says it happened at about seven o'clock Sunday evening.
It says the man had reportedly been causing a disturbance at the grocery store.
When officers arrived, the agency says that the man was standing on a ledge roughly nine metres from the ground in the parking lot.
It says the man fell to the ground a short time later and was pronounced dead after being taken to hospital.
