The Welland Canal is a ship canal that runs 42 km (27 miles) from Lake Erie to Lake Ontario. As part of the St. Lawrence Seaway, the canal allows ships to avoid Niagara Falls by traversing the Niagara Escarpment. The canal has a total of eight locks. Locks four through seven are located in the City of Thorold.
Along the Welland Canals Parkway Trail, see massive 26,000 ton ships up to 226 metres in length glide along the banks on their way to climb the Niagara Escarpment. Ascending 42.5 metres (139.5 ft) in only three lengths of the vessel, the world’s largest flight locks are an engineering marvel to behold.
Lock 4, 5 and 6 make up the Twin Flights Locks. This is where ships climb the mountain as they are raised or lowered in a giant flight of stairs – at the same time!
Lock 7 is the highest point of the Canal system at 174.3 metres (572 ft). At the Lock 7 Viewing Centre, see 23 million gallons of water fill the lock then see ships sail out as you wave to the ship’s crew.
