Snow fall caused a major multi-vehicle pile up on Highway 400 Thursday afternoon. The highway reopened just before 4 p.m. after closing around 1 p.m.

The pile up forced the closure of Highway 400 in both directions from Highway 88 to Innisfil Beach Road, said OPP Sgt. Kerry Schmidt in a video posted on Twitter. About 50 cars and at least six transport trucks were involved, Schmidt said.

The pile up was mainly concentrated in the north-bound lanes by Innisfil Beach Road. “It looks like winter is certainly arriving right now, and it sure looks like Christmas,” he told Twitter as first responders rushed to the area.

Police also dealt with a collision on the Queen Elizabeth Way down at the Garden City Skyway near St. Catharines where a motorist was struck by another vehicle trying to pass, he said.

No injuries were reported following the reopening of the highway.
