A massive crash involving 14 semi-trailers shut down a section of the Trans-Canada Highway near Kenora, Ont. on Thursday.

The highway was closed in northwestern Ontario between Kenora and Vermillion Bay starting around 2 a.m., and one lane of traffic was reopened before noon.

According to the Ontario Provincial Police (OPP), black ice caused two semis to collide near Nixon Lake at about 1 a.m. That led to a chain reaction on the dark, twisting patch of road.

Damage to some of the trucks is extensive but there are only minor injuries, police said, adding that no passenger vehicles were involved.

The OPP say all the semis were loaded and it will likely take some time before the highway reopens.

Drivers were advised to take Highway 71 east of Kenora as an alternate route.
