Guarding the Welland Canal at Port Colborne: A Wartime History

The Welland Canal is the reason ocean-bound grain, iron ore and coal can move between Lake Erie and Lake Ontario without portaging around Niagara Falls. At Port Colborne, the canal meets Lake Erie through Lock 8 - the guard, or control, lock - which at roughly 350 metres (about 1,148 feet) is one of the longest locks in the world. That single waterway carried much of the traffic feeding Great Lakes industry, so in wartime it was not just a piece of civic infrastructure: it was a strategic artery. Disable a lock gate and you could choke shipping for months. That vulnerability is exactly why soldiers, sentries and garrison regiments were stationed along its length, and why the photographs of troops at the Port Colborne Post survive in the city's historical record today.

The threat was not hypothetical. On the evening of 21 April 1900, a dynamite charge was set off against the gate hinges of Lock 24 on the Third Welland Canal, doing limited damage but signalling that the waterway was a deliberate target. The saboteurs were caught nearby in Thorold. The ringleader, John "Dynamite" Luke Dillon - a member of the Irish republican society Clan-na-Gael - along with John Walsh and John Nolan, was tried at the Welland courthouse, convicted, and sentenced to life at Kingston Penitentiary. The key witness was a sixteen-year-old Thorold girl who glimpsed the bombers before the blast knocked her unconscious. The episode hardened the canal's reputation as something that had to be watched around the clock, and it set the precedent for the heavy guard presence that would follow.

When the First World War broke out, the canal became a prize for German-directed saboteurs operating out of New York. In 1914 a plot organised through agents Horst von der Goltz and Franz von Papen aimed to dynamite the Welland Canal and cut the flow of munitions and raw materials moving to Britain's allies. The conspirators obtained explosives, travelled toward the canal to survey it - and found it so heavily guarded that they lost their nerve and abandoned the scheme. The plan only came fully to light later, through seized documents and a saboteur's confession to investigators. The plot's failure is itself a testament to the men on the ground: it was the visible, continuous military guard at the locks that turned would-be bombers away before they ever struck.

The local memory of that guard survives in the Niagara Falls Public Library's Historic Niagara photograph collection, which preserves images of the 2nd Canadian Garrison Regiment at the Port Colborne Post. Garrison regiments were home-defence units whose job was precisely this kind of static guard duty - protecting bridges, locks and shorelines while front-line battalions shipped overseas. Stationed at the canal's Lake Erie entrance, these troops patrolled the approaches to Lock 8, watched the lift and swing bridges, and gave Port Colborne the atmosphere of a garrison town for the duration of the war. For a community better known for grain elevators and flour mills, those archival photographs are a reminder that the harbour was also, for a time, a guarded military frontier.

Visitors can still stand where those sentries once kept watch. Port Colborne's West Street and the canal-side promenade run alongside the Welland Ship Canal, and the viewing area near Lock 8 lets you watch lakers and ocean-going salties rise and fall in the giant guard lock - the same chokepoint that saboteurs once schemed to destroy. Interpretive signage and the nearby Port Colborne Historical and Marine Museum fill in the story, and during the Canal Days festival each summer the waterfront fills with tall ships, vendors and crowds. It is an easy day trip from Niagara Falls, roughly forty minutes south, and pairs naturally with a walk through the historic harbour district. Read together with the city's grain-elevator and railway heritage, the wartime chapter rounds out a fuller picture of why this small Lake Erie town mattered far beyond its size.
