The city of Ottawa is vowing to go all out in the battle against slippery sidewalks this winter, introducing new ice-crushing equipment and adopting a 24/7 approach.
The city is adding another six ice breakers to the four it introduced in March, as well as eight new "hatch blades" to give traditional sidewalk plows that extra edge. The new machinery will also facilitate the spread of salt and sand to either melt the ice or provide better traction for pedestrians.
