Police say they have identified two drivers involved in a "wild crash" on a Toronto stretch of the province's busiest highway that was captured on dashcam video and posted online.

The video shows a large truck pushing a car sideways down the highway and onto the shoulder as traffic hums by. Ontario Provincial Police Sgt. Kerry Schmidt confirmed that the incident happened on Monday.

"When you see the video, it is absolutely shocking," Schmidt said.

Investigators were able to get in touch with both drivers on Tuesday, he added.

The driver of the car, a 41-year-old man from Scarborough, suffered minor injuries.

"He was terrified. Honking his horn, yelling at the top of his lungs," Schmidt said. "He's obviously worried as to how this could have happened in the first place."

The driver of the truck told police he didn't see what was happening in front of him as he was changing lanes.

"That is still has yet to be determined," Schmidt said. "The investigation is still ongoing."

There were two people in the cab of the truck at the time of the collision, he told reporters, and the company that owns the truck reportedly told investigators it was not made aware of it.

At this point, no charges have been laid.

Schmidt said police are "very thankful" that the video was posted online.

"It was very helpful in the investigation to get a better perspective on what happened," he explained.

"Many times with a crash, it's usually one driver against the other, a he-says-she-says type of scenario. When we have dashcam video or a witness come forward, it really helps."
