Ontario Provincial Police say a pedestrian who stepped out of his car on Highway 400 near Barrie this morning was struck and killed by a passing vehicle. 

The incident, which occured shortly before 8:30 a.m., happened in the southbound lanes of the highway near Innisfil Beach Road. 

In a video posted on social media, OPP Sgt. Kerry Schmidt confirmed that the victim got out of his  vehicle after it had broken down on the roadway. 

"It is a construction zone. There is really no shoulders to speak of in that area," he said.

"As the driver was exiting the vehicle, my understanding is they were struck by a passing vehicle."

The driver who was killed was identified by investigators as a 63-year-old man from Barrie. 

A passenger in the vehicle that had broken down was uninjured, according to police. 

The OPP's collision reconstruction unit was on scene and a section of the highway was closed for several hours for the police investigation but all lanes reopened at around 2 p.m. 

Police are asking anyone with dash camera footage of the area at the time to contact investigators.
