Six people were sent to hospital after a highway crash involving multiple vehicles.

Police responded to the collision on Highway 8 between Shakespeare and Stratford around 5:30 p.m. on Thursday.

A tractor trailer and four other vehicles were involved.

“The tractor trailer was exiting from a private driveway, conditions at the time were snowing and blowing and there was a chain reaction collision where the four sedans collided with the rear of the tractor trailer,” said Cst. Barry Cookson.
