All eastbound lanes of Highway 401 have been shut down at Islington Avenue as police carry out an investigation near Keele Street, OPP say.

Keele Street has been closed both ways in the area too as police investigate.

It’s not clear how long the closure will last.

“We are dealing with a very tough drive on the eastbound 401 and I would actually suggest sticking with the eastbound 407 or city streets,” CP24 Traffic Specialist Lisa Morales said. “It is a really frustrating commute for motorists in that vicinity.”

Police are advising motorists to use alternate routes for the time being.
