Welland Canal Welland Canal The 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. Traversing the Niagara Peninsula from Port Weller to Port Colborne, it enables ships to ascend and descend the Niagara Escarpment and bypass Niagara Falls. The canal carries about 3,000 ships which carry about 40,000,000 tons of cargo a year. It was a major factor in the growth of the city of Toronto, Ontario.

In 1887, a new shorter alignment was completed between St. Catharines and Port Dalhousie. One of the most interesting features of this third Welland Canal was the Merritton Tunnel,
