Cargo ships travelling between Lake Ontario and Lake Erie cannot use the Niagara River: the falls and the rapids around them make that stretch impassable. The Welland Canal exists to get around the escarpment instead, lifting or lowering ships 99.5 metres over a run of about 43 kilometres. The canal running today is the fourth version, opened in 1932, and it uses eight locks. The first canal, built in the 19th century, needed 40 locks to cover the same climb in smaller steps. Confusing the two figures is easy and common; the number that matters for a ship crossing today is eight. ![A cargo ship inside a lock chamber of the Welland Canal at St. Catharines](https://www.bestwesternfallsview.com/wp-content/uploads/2026/09/canal-welland-corps.jpg) *A ship rises through one of the canal's eight locks.* ## Why the canal is here at all Niagara Falls sits on an escarpment that separates the two lakes by 99.5 metres of elevation, and no ship built for the Great Lakes trade can go over it or through it. The canal solves the problem the way canals always have, by building a staircase of locks around the obstacle instead of trying to remove it. About 3,000 ships make the crossing each year, carrying roughly 40 million tonnes of cargo, over a canal that runs about 43 kilometres from lake to lake. None of that traffic is visible from the falls themselves, which sit a short drive east of the canal's route. Visitors who spend a day at the brink and never hear about the Welland Canal are missing the half of the Niagara story that has nothing to do with sightseeing: the half that keeps the Great Lakes shipping trade running at all. **The climb in numbers** Eight locks carry ships 99.5 metres between the lakes, over a canal about 43 kilometres long. A full transit takes roughly 11 hours. ## Eight locks, not forty The Welland Canal has been rebuilt three times since the first version opened. Each rebuild made the locks bigger and cut their number, from 40 down to the eight in use since the current canal opened in 1932. A lock does one job: it raises or lowers the water level inside a chamber so a ship can move from one section of canal to the next without a waterfall in the way. Fewer, larger locks move more tonnage faster than a long chain of small ones, which is most of why the older 40-lock canal was replaced rather than kept running alongside its successors. It is worth being precise about which number belongs to which canal, because the two get mixed up constantly in casual writing about Niagara. Forty locks is a fact about a canal that no longer exists in that form. Eight locks is a fact about the one ships use this year. **A canal, not a shortcut** Forty locks on the 19th-century canal became eight on the current one, opened in 1932. The two numbers describe different canals, not different counts of the same thing. ## What Lock 3 shows you The place to watch this happen without a boat ticket is the Lock 3 viewing centre in St. Catharines. From the platform there, a ship enters the chamber, the gates close behind it, and the water level changes around it while the hull stays still relative to the lock walls. The scale is easy to underestimate from photographs: a laker fills most of the chamber's width, and it moves slowly enough that the change in water level, not the ship itself, is what actually holds your attention. Nothing about the process is fast, which is part of what makes it worth watching in person rather than in a clip. A transit of the full canal runs about 11 hours end to end, and no single lock viewing shows more than a fraction of that. What it shows instead is the mechanism itself: gates, chambers, and a ship several storeys tall being walked uphill a step at a time, in full view of anyone standing on the platform. **Before you go** The canal operates from late March to December and closes for the winter. There is no ticket or booking involved at Lock 3: the viewing platform is open to whoever turns up. ## Timing the visit A stop at Lock 3 works best as part of a day already spent in the Niagara region, rather than a special trip built around one ship. The canal's working season runs from late March into December; outside those months the chambers stand empty and there is nothing to watch. Inside the season, patience is the only requirement: with roughly 3,000 transits spread across those months, a ship will come, even if the exact hour is a matter of waiting rather than scheduling. Most visitors to Niagara Falls never see this part of the region at all. The falls themselves draw the crowds, and the canal runs quietly a short drive away, doing the unglamorous work of keeping Great Lakes shipping connected without a waterfall in the way. Adding an hour at Lock 3 to a day built around the falls costs little and shows a side of the region that has nothing to do with scenery: a piece of working infrastructure that has been solving the same problem, in four different forms, for close to two centuries. What holds the attention at the lock is not speed but scale. A ship several storeys tall, loaded with cargo bound for a port on another lake entirely, comes to a stop inside a concrete chamber and simply waits while the water around it rises or falls to match the next stretch of canal. There is no equivalent sight anywhere else along the Niagara Parkway, and none of it depends on the falls being nearby at all. --- ## À propos de l'auteur **Falls View** — Die Redaktion von Mein Südtirol: Pässe, Mautgebühren und Öffnungstermine, jede Angabe mit ihrem Datum.
