A 24-year-old man from Moncton, N.B. was taken to hospital with what police are calling serious injuries after a Friday morning collision on the Trans-Canada Highway in northwestern Ontario.

According to Ontario Provincial Police, around 7 a.m., a vehicle travelling west on Highway 17 near Marathon, east of Thunder Bay, collided with the rear wheels of a tractor trailer going in the opposite direction. The 24-year-old had to be extricated from the vehicle by firefighters.

The man was taken to hospital while three other people involved in the crash — two in the transport and one in the other vehicle — were treated at the scene for minor injuries, police said.

Highway 17 was reportedly closed for about an hour and re-opened to one lane of traffic around 10:30 a.m.

Drivers should expect delays in the area, according to police.
