A three-year-old boy who was hit by a car near Toronto Street and Notre Dame Avenue late Sunday afternoon has died, according to police and the child's father.

Emergency crews were called to a back lane between Toronto and Victor streets at around 4:15 p.m., after reports came in of a motor vehicle collision involving a pedestrian.

Robert Scherban told CBC News his son, Robert, was playing behind his home and appeared to have wandered out to the back lane just as a car was passing by.

​​"The reason why I lost my son, I believe, is because of speeding — speeding in the back alleys," Scherban said.

"He was playing. The last time I've seen him was a minute before that happened. I gave him a Subway sandwich and then the next minute later, he was gone."

Scherban said he did not see the collision, but as soon as he found Robert on the ground he started administering CPR.

"I tried to do my best and once I noticed he wasn't breathing anymore, I just started running around and telling people everywhere to call 911," he said.

Robert was taken to hospital in critical condition. Police confirmed on Sunday night that he has died.

The driver of the vehicle, who immediately stopped and called 911, was interviewed by police but no charges have been laid.

Speed and alcohol are not considered factors in the crash, police said, adding the investigation is continuing.
