The Ontario Provincial Police (OPP) says the ongoing snowstorm is making roads dangerous and urges residents to stay off them if possible.
Heavy snowfall is creating treacherous driving conditions, leading to delays in the area.
Drivers are advised to avoid Highway 43 while crews work to clear the scene.
