Former U.S. President Donald Trump vowed to block the new Gordie Howie bridge between Ontario and Michigan unless Washington gains 50% ownership, claiming Canada bypassed U.S. approval processes. In a Truth Social post, Trump alleged predecessor Barack Obama enabled Canada to avoid buying American materials for the crossing, demanding compensation for alleged losses.

The C$6.4 billion ($4.8 billion) project, fully funded by Canada through its Windsor-Detroit Bridge Authority, is scheduled to open in early 2026. Trump’s demand arrives as bilateral tensions rise over Canada’s pursuit of Chinese trade partnerships, which he called a national security threat without evidence.

This marks Trump’s latest intervention in North American infrastructure disputes. The bridge’s construction began in 2012 under a Canadian federal agency, designed to ease congestion at the busy Ambassador Crossing. Trade analysts warn the ultimatum could disrupt supply chains affecting auto manufacturers and agricultural exporters.
