The collision happened on the QEW, between McLeod and Sodom roads at around 12:30 p.m., Ontario Provincial Police said.
“We have one confirmed fatality at the scene – a single person in a passenger vehicle collided with equipment in a construction zone,” Sgt. Kerry Schmidt said in a social media post.
There is no information yet about the identity of the person who died.
The QEW was shut down in both directions between McLeod and Sodom roads for several hours as a collision reconstruction team looked into the deadly crash. The highway has since reopened in both directions.
