The Icebreaking Service's main activities in the Quebec Region are:

• Ice-route assignment in order to facilitate the transit of marine traffic in ice-infested waters, and the escort of commercial vessels experiencing transit difficulties due to ice conditions in the Estuary and Gulf of St. Lawrence;
  


• Flood control, by ensuring a free movement of the ice, and prevention of ice-jam formation, particularly at the St. Lawrence River's more pronounced curves, in the vicinity of bridges spanning it and at the mouth of tributary rivers.
