Police say blustery snow squalls caused a pileup of nearly 100 vehicles on a busy highway north of Toronto.

Ontarior provincial police spokesman Sgt. Dave Woodford officers counted 96 vehicles involved the chain-reaction crash Thursday morning on Highway 400's southbound lanes.

No major injuries have been reported.

It happened after a snow squall moved into the region off Lake Huron and Georgian Bay, creating whiteout conditions on the highway.

Provincial police reported several highway closures across southwestern Ontario on Thursday.
