OPP are reminding motorists to clear all the ice off your vehicle before heading out.
They say they received dozens of calls yesterday about chunks of ice flying off vehicles.
In one incident on Highway 400 near Finch Ave a large piece off ice flew off a truck heading southbound and smashed through the windshield of a car travelling northbound.
The driver was treated on the scene.
OPP Sgt. Kerry Schmidt says it could have been a lot worse
