Grandparents, grandchild among 4 dead in wrong-way 401 pursuit crash

Two grandparents and their infant grandchild were killed on a busy stretch of Highway 401 on Monday night after a van being chased by police east of Toronto crashed while going the wrong way, causing a multi-vehicle collision.

The crash – which also left the person in the suspect van dead raised questions about the police pursuit that had been triggered by an alleged liquor store robbery, as Ontario's police watchdog began its investigation into what happened.

"It was a really big collision scene, and we're still trying to get to the bottom of how many vehicles, how were they involved, where people were from," Monica Hudon, a spokeswoman for the Special Investigations Unit said at a news conference Tuesday.

"As part of the investigation, we are going to look into the pursuit. When it started, where it started, what transpired."

The SIU said an off-duty police officer first reported an alleged robbery at an LCBO in Clarington, Ont., around 7:50 p.m. Monday to Durham Region police. Officers then found a cargo van of interest and began pursuing it, the watchdog said.

"Officers followed the cargo van through numerous streets in Durham region as the vehicle drove erratically," Hudon said.

Police continued their pursuit as the van got on to Highway 401 near Stevenson Road and began travelling west in eastbound lanes, she said.

About 20 minutes after the chase began, there was a crash involving six vehicles, Hudon said.

"Three individuals from a civilian vehicle were pronounced deceased at the scene, and in that vehicle were a 60-year-old, a 55-year-old, and an infant," Hudon said, adding that the infant was the grandchild of the adults killed.

She said another person was taken to the hospital with serious injuries

The SIU, which invokes its mandate any time a police officer has been involved in a serious injury, death or sexual assault, said it is investigating the circumstances of the crash and what led to it, including the police pursuit.

Hudon said she did not know if the police pursuit was called off or if officers were asked to pull back before the suspect van got onto the highway.

"It's still really early stages," she said, adding that police policies around pursuits would be part of what's examined. "We will be getting communications, recordings, doing interviews to figure out what happened, when and why."

Hudon did not have further information on the grandparents and infant killed.

The Durham Regional Police Service wrote in a post on X, formerly known as Twitter, that they had been called to a robbery in Clarington, the suspect fled when officers arrived and a pursuit began.

"The suspect proceeded onto the 401 highway in the opposite direction, resulting in a multi-vehicle collision with fatalities," the force wrote, saying further information would follow.

Ontario Premier Doug Ford called the crash "heart wrenching."

"My heart goes out to the family and my condolences go out to them," he said.

"When you see everyone from a grandfather to a little baby, the loss of lives because someone decides to rob a liquor store and go on the other side of the highway, it's a tragedy."
