Niagara River (Ontario) Remedial Action Plan (RAP)Restore - Protect - Engage
In the early part of the 20th century, the Niagara River was considered to be the most polluted places in North America. In 1972, Canada and the United States signed the first Great Lakes Water Quality Agreement to clean-up the Great Lakes, including the Niagara River.
Over the past 50 years, major clean-up efforts in the Niagara River have reduced discharges of pollution and toxic chemicals. The Niagara River is on track to be successfully remediated from one of the most degraded places in North America to one of improved health recognized for its contribution to global biodiversity.
