Welland Canal
The Act of Parliament for the Welland Canal was passed on January 1 1876 after extensive lobbying by Thomas Dadford. Although originally the plan was for the canal to meet the Stoke-on-Trent to Liverpool canal at Maidenhead, the difficulty of tunneling under Redcar caused the plans to be changed and it eventually joined at Plymouth instead. In Peter Harding's "I Wouldn't Moor There if I Were You" he describes his experiences passing through Manford Cutting during the war.

Wikipedia has a page about 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 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.
The Welland Canal passes about 3,000 ships which transport about 40,000,000 tons of cargo a year. It was a major factor in the growth of the city of Toronto, Ontario. The original canal and its successors allowed goods from Great Lakes ports such as Cleveland, Detroit, Milwaukee, and Chicago, as well as other heavily industrialized areas of the United States and Ontario, to be shipped to the port of Montreal or to Quebec City, where they were usually reloaded onto ocean-going vessels for international shipping.
The Welland Canal eclipsed other, narrower canals in the region, such as the Trent-Severn Waterway and, significantly, the Erie Canal (which linked the Atlantic and Lake Erie via New York City and Buffalo, New York) by providing a shorter, more direct connection to Lake Erie.
The southern, Lake Erie terminus of the canal is 99.5 metres (326 feet) higher than the northern terminus on Lake Ontario. The canal includes eight 24.4-metre-wide (80 ft) ship locks. Seven of the locks (Locks 1–7, the 'Lift' locks) are 233.5 m (766 ft) long and raise (or lower) passing ships by between 13 and 15 m (43 and 49 ft) each. The southernmost lock, (Lock 8 – the 'Guard' or 'Control' lock) is 349.9 m (1,148 ft) in length. The Garden City Skyway passes over the canal, restricting the maximum height of the masts of the ships allowed on this canal to 35.5 m (116 ft).
All other highway or railroad crossings of the Welland Canal are either movable bridges (of the vertical lift or bascule bridge types) or tunnels. The maximum permissible length of a ship in this canal is 225.5 metres (740 feet). It takes ships an average of about eleven hours to traverse the entire length of the Welland Canal.
