Two people in their 20s were forced to evacuate their car as it slid off the road into the freezing waters of the Lac des Deux Montagnes in Vaudreuil-Dorion, just west of Montreal.
The incident happened just after midnight Wednesday on de Breslay Street, a quiet road just north of Highway 40 that ends at the water’s edge.
