The plant discharges into the St. Lawrence River watershed, which flows through Ontario and Quebec before reaching the Gulf of St. Lawrence and the Atlantic Ocean. The St. Lawrence River supports diverse aquatic life, including fish species such as sturgeon and walleye, and provides critical habitat for migratory birds. Protecting water quality in this system is essential for maintaining ecological health and supporting local communities.
