A formal ribbon-cutting had been planned for Friday for the Gordie Howe International Bridge, according to invitations seen by Reuters.
“Canada and the United States have agreed to delay the opening of the bridge, taking the necessary time to resolve any outstanding issues,” the Windsor-Detroit Bridge Authority said.
Canadian Prime Minister Mark Carney said Canada agreed to delay the opening at the request of the Trump administration.
“We agreed to delay the opening and take the necessary time to resolve outstanding issues,” Carney said at an event in Toronto, without detailing what those issues were.
“For a bridge that is going to be in place and serve Canadians, Americans, others for decades, the question of a few weeks is time well spent,” he added.
Windsor Mayor Drew Dilkens said on X that while officials want to see the bridge open, “Canada need not fall on bent knee to make it happen.”
Pete Hoekstra, the US ambassador to Canada, told The Detroit News that he and Commerce Secretary Howard Lutnick are leading discussions with Canada about opening the bridge. Lutnick’s office did not immediately respond to a request for comment.
The White House has not commented.
Trump in February cited Canada’s refusal to stock some US alcoholic beverages on Canadian store shelves, Canada’s tariffs on dairy products and its trade talks with China as grounds for why he might not allow the bridge to open.
Matthew Moroun, owner of the rival Ambassador Bridge that connects Detroit and Windsor, in February met with Lutnick and weeks earlier had donated $1 million to a Trump-aligned political action committee. House Democrats have suggested that Moroun used his influence to “jeopardise American commerce” to protect his company’s bottom line.
The Detroit International Bridge Company, which runs the Ambassador Bridge, did not respond to an emailed request for comment.
Construction of the bridge, which began in 2018, was financed by Canada because the US refused to pay for it. The costs will be covered by tolls over 30 years.
Homeland Security Secretary Markwayne Mullin said at a Senate hearing last week that the department was good to go to staff the Gordie Howe bridge.
The new bridge will help ease truck traffic on the Ambassador Bridge into Detroit, the largest freight port on the US-Canada border, which handled $126 billion of value traded by commercial trucks as of 2023.
It will cut 20 minutes off the crossing time, saving truckers $2.3 billion over 30 years, according to a University of Windsor study.
Trump has made several threats against Canada in his second term and drastically hiked tariffs on the US northern neighbour. This week, Trump said he might not renew a free trade deal with Mexico and Canada.
