A tow truck driver injured in a shooting in Toronto drove himself to hospital for treatment on Wednesday night, Toronto police say.

The shooting happened near Leslie Street and Highway 401. Police were called to the scene at 7:22 p.m.

Insp. Jim Gotell, spokesperson for the Toronto Police Service, told reporters at the scene that the man is being treated in hospital for a non-life-threatening gunshot wound.

Gotell said police have determined that the shooting occurred relatively close to the hospital where the man went for treatment.

"At this point in time, we do know that the victim was driving a tow truck at the time he was shot," Gotell said.

One person has already come forward with dashboard camera video of the incident, he added.

On Wednesday night, police were on the scene, looking for more witnesses and security camera video.

"We have some pretty good information right now and we are working with that," Gotell said.

He said it took time for police to determine where the shooting actually happened and it is too early to say if the shooting is related to recent conflicts among tow truck drivers in the Greater Toronto Area.

No description of a suspect has been released.

Police have closed Leslie Street between Esther Shiner Boulevard and Highway 401. The closures include Highway 401 on and off ramps in the area.

Anyone who was in the area at the time of the shooting, or who has dashboard camera video of southbound Leslie Street near Highway 401 from just before 7:30 p.m., is urged to call police 33 Division at (416) 808-3300.
