A pileup involving nearly 20 vehicles occurred in the late evening Friday on Highway 401, east of Toronto, killed three people and more than 15 injured, five of whom are in critical condition.
The tragedy occurred on Friday night at the height of Whitby.
A trailer would have crashed into a group of vehicles that had slowed approaching a construction site, causing several other collisions.
A man, a woman and a young boy died in the pileup, said the sergeant of the Ontario Provincial Police, Kerry Schmidt, adding that nearly 20 vehicles, including four semi-trailers were involved in collisions in the westbound lanes of the highway.
Besides the five wounded in critical condition, 11 others suffered serious injuries and were transported to hospital.
Highway 401, one of the busiest in Canada, was closed in both directions and should not reopen before the end of the day on Saturday. Mr. Schmidt said that the road was dry and the weather and visibility were good at the time of collision.
“With all these crushed vehicles, it’s an amazing scene of aluminum and twisted steel of these vehicles that are similar even to auto,” the sergeant said.
