Police are investigating after an SUV rolled into a ditch north of Toronto Saturday night, killing its driver.

Peel Regional Police were called to the single-motor vehicle crash in King Township at 8:50 p.m. where they found the SUV resting in the south-bound ditch of the road.

The motorist was pronounced dead at the scene after his grey-coloured vehicle "rolled over and over" again on Concession Road 11 south of Sideroad 15, Insp. Gary Minor told CTV Toronto.

Minor said from the debris and tire marks, investigators believe the driver had somehow lost control of the vehicle but "what made the operator loose control is of interest to us."

Police said the driver had somehow been ejected from the SUV.

Anyone with information is asked to contact Traffic Reconstruction at 905-830-0303 ext. 7704 or Crime Stoppers at 1-800-222-TIPS.
