Mark Campbell told CTV News Toronto that he witnessed the incident, calling it “pretty traumatic.”

The construction worker said he was standing about 20 feet away when he saw the driver of the vehicle reverse out of the driveway, turn the wheel and proceed forward. Campbell said that he heard a child scream and went running towards the car.

“The front bumper struck the child, because the child ran out and he didn’t see the child and just ran him over.”

As the driver carried the boy into the home, Campbell said he called police.

Police said the boy was airlifted to hospital, where he remains in a stable condition.
