WLake Erie is the fourth-largest lake of the five Great Lakes in North America, and the eleventh-largest globally if measured in terms of surface area. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. At its deepest point Lake Erie is 210 feet deep.
WLake Ontario is one of the five Great Lakes of North America. It is surrounded on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the American state of New York, whose water boundaries meet in the middle of the lake.

According to Iroquoian scholar Bruce Trigger, Niagara is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the Niagagarega people on several late-17th-century French maps of the area. According to George R. Stewart, it comes from the name of an Iroquois town called Ongniaahra, meaning "point of land cut in two".

In between, it passes through the towns of Les Cèdres and Coteau-du-Lac. It superseded the first Beauharnois Canal which was on the south shore of the Saint Lawrence. It is 23 kilometers (14 mi) long and had a 4.3-meter (14.1 ft) draught. Five locks measuring 85.3 m × 14 m give a total rise of 25 meters (82 ft).
WThe Welland Canal is a ship canal in Ontario, Canada, connecting Lake Ontario and Lake Erie. It forms a key section of the St. Lawrence Seaway and Great Lakes Waterway. Traversing the Niagara Peninsula from Port Weller in St. Catharines to Port Colborne, it enables ships to ascend and descend the Niagara Escarpment and bypass Niagara Falls. The name currently refers to the fourth such canal, three earlier and much smaller canals servicing the same route are also known as the Welland.
