Truck carrying dog food rolls over on Highway 409

The OPP says a tractor-trailer carrying dog food rolled over on a Toronto highway on Tuesday afternoon, and they expect it to cause delays for commuters heading home from work.

The rollover happened in the eastbound lanes of Highway 409, just east of Highway 427.

An OPP spokesperson says that the shoulder and left lane are currently blocked.

The incident has forced the closure of the northbound and southbound ramps leading from Highway 427 to Highway 409.

The closures are expected to last until about 5 p.m.
