A man is dead after a collision involving a tractor-trailer on the Linc in Ancaster Monday morning.

The incident happened just after 6:30 a.m. The Linc itself is now open after a lengthy closure but the on and off ramp at Mohawk and Golf Links road will remain closed for some time as crews clear the scene.

A man in his 60s who was driving the tractor-trailer is dead, police say.

Both the Hamilton police Collision Reconstruction Unit and the Ministry of Transportation (MTO) have been called in.

“Hamilton police ask that commuters avoid this area as crews continue to work safely to investigate this fatal collision,” Hamilton police tweeted.

Police are asking people to find an alternate route and to expect delays. The cause of the accident hasn't been determined, police say.

Hamilton fire crews were also called in, but Fire Information Officer Claudio Mostacci said he couldn't say if firefighters had attempted a rescue or extraction of the man in the truck. "It's a police matter now," he said.

MTO officials were brought in to do a mechanical inspection of the truck and trailer, spokesperson Bob Nichols told CBC Hamilton.

"The damage was extensive and the driver’s body was still inside pending the arrival of the coroner," he said. "Our truck enforcement officers were able to partially examine the brakes and tires, although access was limited given the state of the vehicle, the placement of it in the ditch, and the presence of the driver’s body."

This is Hamilton's 17th traffic fatality of the year.

There was also another crash in the area Monday morning. Ontario Provincial police reported a three-vehicle crash on the eastbound lanes of the 403 between Wilson Street and Hwy 52. Cars were struck by pieces of a tractor wheel that had become dislodged, police say.

There were minor injuries.
