A joint ceremony between the United States and Canada is no longer expected on Friday to celebrate the opening of the Gordie Howe International Bridge connecting Detroit and Windsor, Ontario, after President Donald Trump announced the imposition of 50 percent tariffs on most Canadian goods.

Trump, in announcing the tariffs, accused Canada of unfairly discriminating against American cars, alcoholic beverages, and dairy products, escalating tensions with one of the United States' closest allies.

"In light of the trade actions threatened by the United States earlier this week, it would be inappropriate to proceed with a celebratory event between the two countries," said a spokesperson for Canadian Infrastructure Minister Gregor Robertson in an email statement.

The move came after U.S. and Canadian officials earlier this month reached an agreement to open the Gordie Howe International Bridge, following delays linked to disagreements between the two countries.

Canada now plans to hold its own ceremony on Friday, while it remains unclear whether the United States will hold a separate ceremony.

Two U.S. officials, speaking on condition of anonymity to discuss internal deliberations, said they still expect the bridge to open to traffic on July 27, but they are less certain than before.
