One man is dead after a six vehicle crash Wednesday morning on Highway 401 in Ajax.
An SUV was crushed between a couple of tractor trailers.
Another person from another vehicle suffered life threatening injuries.
All eastbound lanes of the 401 have been closed between Salem and Westney Roads, but they may re-open by noon or so.
Sgt. Kerry Schmidt says fog may have been a factor in the crash, but the investigation continues.
