Toronto police are blaming road rage after a motorist's vehicle was blasted with two rounds of ammunition on Tuesday.

Police said the victim cut off a man in a gold-coloured four-door sedan near Markham Road and Highway 401 shortly before noon on Tuesday.

Police say the suspect followed the victim to Meadowvale Road and Ellesmere Road, where he pulled out a handgun and shot at his target's car door.

"There was very little provocation," Toronto Police Sergeant Robert Duthie told CTV Toronto. "The reaction of the assailant doesn't justify the force that was utilized."

The driver, who said he sped up when he saw the gun, was only missed by a narrow margin.

The suspect is between 20 and 25 years old, black and has short, wavy black hair and a thin beard resembling a chin-strap. He was last seen driving away on Meadowvale Road.

The shooting was one of two drive-bys in Toronto on Tuesday. The other sent one man to the hospital with serious injuries after at least five shots were fired at a car at a plaza parking lot on Weston Road.
