Canadian leaders are planning their own event Friday without any American officials to celebrate the construction of the $4.7 billion Gordie Howe International Bridge over the Detroit River amid trade tensions with the United States.

On Tuesday, Canadian leaders told Michigan officials they planned to cancel a joint U.S.-Canada event planned for Friday to celebrate the opening of the Gordie Howe International Bridge after President Donald Trump leveled new tariffs on America's northern neighbor, according to three sources briefed on the decision.

"The July 24, 2026, event for the Gordie Howe International Bridge has been cancelled," according to an email sent late Tuesday from the Windsor-Detroit Bridge Authority to one U.S. elected official.

"We appreciate your interest. We regret any inconvenience and appreciate your understanding."

The scuttling of a two-nation event celebrating the new Detroit River span is not expected to interrupt Monday's planned opening of the bridge. Canada's infrastructure ministry in a statement said it remains "committed" to the June 27 opening.

"In light of trade action threatened by the United States earlier this week, it would be inappropriate to proceed with a celebratory event between the two countries," Canada's infrastructure ministry said in a statement.

"The Gordie Howe International Bridge remains a vital infrastructure project that reflects years of hard work and will be a major economic driver in the region, expanding options for commuters, tourists, businesses, and families."

On Wednesday morning, the Windsor-Detroit Bridge Authority announced a "Canadian Celebration" of the new bridge on Friday morning on the Windsor side of the 1.5-mile span. Gregor Robertson, Canada's minister of housing and infrastructure, will be attending the event, according to a media advisory.

Canadian officials informed Michigan VIPs about the cancellation of the the joint Canadian-U.S. event a day after Trump imposed new 50% tariffs on a wide range of goods, including Canadian cement, wine, dairy and hockey sticks.

This marks the second time in two months that a planned ribbon-cutting ceremony was called off amid disputes between the two countries. The first one, scheduled for June 12, was called off after Trump administration officials sought to fulfill Trump's demand to get a "better" deal for America in the bridge jointly owned by Canada and Michigan.

Earlier this month, Canadian Prime Minister Mark Carney's administration agreed to a split of any toll profits for the U.S. for economic development efforts on the American side of the Detroit River border.

Earlier Tuesday, Michigan Gov. Gretchen Whitmer was asked whether she believed there would be further delays to the bridge’s opening.

“I sure hope not," Whitmer told reporters at a budget bill signing ceremony in Southfield.

Whitmer, a Democrat, slammed the Republican president's fluctuating, “capricious” tariff policy and said it was impacting Michigan more than most.

“We are sensitive to all of these capricious rule changes,” Whitmer said. “I do worry about the long-term ramifications of this, but the short-term ramifications are painful for Michiganders. So I was really beside myself to see yet another iteration come out yesterday.”
