U.S. President Donald Trump threatened Monday to block the opening of the Gordie Howe International Bridge, a key infrastructure project connecting Detroit, Michigan, and Windsor, Ontario, escalating a trade dispute with Canada and raising concerns about economic repercussions for both countries.
In a post on his Truth Social platform, Trump stated he would “not allow” the bridge to open until “the United States is fully compensated for everything we have given them,” and Canada demonstrates “Fairness and Respect.” He announced the immediate commencement of negotiations, but offered no specifics on how he intends to prevent the bridge’s opening.
The Gordie Howe International Bridge, named for the legendary Canadian hockey player, is a 1.5-mile structure designed to ease congestion at the existing Ambassador Bridge and improve trade flow between the two nations. Major construction is complete, and the bridge is expected to open this year following a period of testing, according to the Windsor-Detroit Bridge Authority, which oversees the project.
Trump’s claims that Canada “owns both the Canada and the United States side” and built the bridge “with virtually no US content” are inaccurate. The more than $4 billion bridge is being fully funded by Ottawa, but will be jointly owned by the Canadian government and the state of Michigan, as stipulated in a 2012 agreement. The agreement mandates that any iron and steel used in the bridge’s construction originate from either the United States or Canada, ensuring equitable sourcing.
Windsor Mayor Drew Dilkens responded to Trump’s statement, telling CNN’s Canadian partner CBC News that U.S. Steel was used in the construction of the bridge on the Michigan side. “It’s just insane,” Dilkens said.
The threat to delay the bridge opening is the latest in a series of escalating tensions between the Trump administration and Canada. Earlier this year, Trump announced his intention to decertify all aircraft manufactured in Canada and proposed a 50% tariff on Canadian-made planes. He has also threatened a 100% tariff on all Canadian goods should Canada pursue a trade deal with China, warning that China “will eat Canada alive.”
Recent developments include a “new strategic partnership” formed last month between Canadian Prime Minister Mark Carney and Chinese leader Xi Jinping. This partnership involves Canada easing tariffs on Chinese electric vehicles, allowing up to 49,000 annually, even as China is expected to reduce barriers on Canadian canola seed, lobster, and peas.
These disputes are unfolding as the United States, Mexico, and Canada prepare for a scheduled review of the United States-Mexico-Canada Agreement (USMCA), the trade deal renegotiated by Trump during his first term. Trump also complained Monday that Ontario, Canada’s most populous province, “won’t even put U.S. Spirits, beverages, and other alcoholic products, on their shelves,” a move taken by Ontario and other Canadian provinces in protest of U.S. Tariffs on Canadian goods.
Despite the current friction, Trump previously acknowledged the bridge’s importance to the U.S. Economy. A 2017 joint statement with former Canadian Prime Minister Justin Trudeau described the Gordie Howe Bridge as “a vital economic link between the two countries.”
Michigan Senator Elissa Slotkin, a Democrat, warned that blocking the project would have “serious repercussions” for the state’s economy, stating on X, “The President is punishing Michiganders for a trade war he started. Canada is our friend — not our enemy.”
The White House, Prime Minister Carney’s office, Michigan Governor Gretchen Whitmer, and the Windsor-Detroit Bridge Authority have not yet issued public responses to Trump’s latest threat.
