Trump Threatens to Block Gordie Howe Bridge Opening, Escalating US-Canada Tensions

A major diplomatic and trade dispute is brewing between the United States and Canada over a vital new border crossing. President Donald Trump has publicly threatened to delay or block the opening of the Gordie Howe International Bridge, which connects Detroit, Michigan, and Windsor, Ontario. The multi-billion-dollar infrastructure project, jointly funded by Canada and Michigan and nearing completion, aims to ease congestion and modernise North America's busiest trade corridor.

President Trump has criticised the project, claiming it unfairly disadvantages the privately owned Ambassador Bridge and the United States. He has suggested using federal authority over border crossings to stop the bridge's opening, framing it as leverage to renegotiate trade terms with Canada under the USMCA agreement. This threat directly challenges years of binational planning and investment.

The Canadian government and the Premier of Ontario have issued strong rebukes, calling the threat harmful and illogical for the deeply integrated North American economy. The potential blockade raises immediate concerns for the automotive industry and other manufacturers whose just-in-time supply chains rely on dependable crossings. Analysts warn that hindering the bridge could disrupt billions in daily trade, signalling a significant escalation in employing critical infrastructure as a tool in bilateral negotiations.
