A multi-vehicle crash involving a tanker trailer has closed the eastbound and westbound lanes of Highway 401 near Avenue Road.
Provincial police say the incident occurred in the westbound lanes just after 11 p.m. It was unclear how many vehicles were involved or the extent of injuries.
Highway camera photos show a tanker truck blocking the westbound portion of the express lanes while a portion of the concrete barrier separating the express lanes has been damaged, with large pieces of concrete debris strewn across the eastbound portion of the highway.
Paramedics tell CityNews they had transported one man to a trauma centre with serious but non-life threatening injuries, but were still on the scene assessing patients.
One lane of the eastbound portion of the highway was opened to allow traffic to pass through shortly after midnight.
