Canada has cancelled plans for a joint ceremony with the United States celebrating the opening of the Gordie Howe International Bridge following President Donald Trump’s announcement of new 50% tariffs on Canadian goods.

Officials from both countries had been expected to attend the cross-border celebration on Friday, July 24. The bridge connects Detroit, Michigan, with Windsor, Ontario, across the Detroit River.

The Canadian government said holding a shared celebratory event would be inappropriate following the latest trade measures threatened by Washington. Canada will instead hold its own ceremony on Friday.

It remains unclear whether the United States will organize a separate event on its side of the border.

Trump announced the tariffs earlier this week, accusing Canada of unfairly discriminating against American automobiles, alcoholic beverages and dairy products. The decision has further strained relations between two countries with deeply integrated economies and one of the world’s largest bilateral trading relationships.

The cancellation comes only weeks after Canadian and American officials reached an agreement allowing the long-delayed bridge opening to move forward.

Despite the dispute, officials still expect the bridge to open to traffic on July 27. However, uncertainty surrounding the opening has increased following the cancellation of the joint ceremony.

The Gordie Howe International Bridge was designed to strengthen trade and transportation between Canada and the United States while reducing congestion at existing border crossings in the Detroit-Windsor region.

The crossing is expected to become a major route for commercial vehicles travelling between the two countries. Its opening carries considerable economic importance for manufacturers and businesses that depend on cross-border supply chains.

The latest disagreement highlights how trade tensions have begun affecting even projects originally promoted as symbols of cooperation between Washington and Ottawa.
