An Ontario Provincial Police officer has been injured in Dufferin County, north of Toronto, where blowing snow and extremely cold temperatures have resulted in a state of emergency.

The officer was investigating a collision involving a transport truck Wednesday afternoon when another truck hit her police cruiser from behind making it collide with the first truck, according to Const. Paul Nancekivell.

The officer has since been treated in hospital and released.

The OPP are warning drivers to stay away from the roads in Dufferin County because of the weather which has caused a number of road closures.

The state of emergency was declared Wednesday afternoon by County Warden Bill Hill, who added that the weather has critically impacted infrastructure in the area.

“Local resources have been exhausted and mutual assistance agreements need to be implemented to further manage this situation,” a release from the county read.
