The border between New York State, USA and Ontario, Canada is formed entirely by waterways. Lake Ontario is the longest stretch of the border. The rivers which form the rest of the border are the Niagara River, which flows from Lake Erie into Lake Ontario, and the Saint Lawrence River, which flows from Lake Ontario out to the Gulf of Saint Lawrence and the Atlantic Ocean.
The border between Ontario, Canada, and New York, USA, runs through the entire length of the Niagara River (from Lake Erie to Lake Ontario), as well as through that part of the St Lawrence River between Lake Ontario and the 45th parallel of latitude (which is near Cornwall, Ontario).Niagra River
