The US president has demanded ownership of “at least half” of the crossing between Ontario and Michigan
President Donald Trump has threatened to block the opening of a major new bridge linking Canada and the United States unless Washington receives compensation and a partial ownership stake in the project.
In a lengthy post on his Truth Social platform on Monday, Trump said he would not allow the Gordie Howe International Bridge – connecting Windsor, Ontario, and Detroit, Michigan – to open until the United States is “fully compensated” and Canada treats the US with what he described as “fairness and respect.”
“With all that we have given them, we should own, perhaps, at least one half of this asset. The revenues generated because of the US market will be astronomical,” he wrote.
Trump accused Canada of benefiting disproportionately from the project, claiming it was built with “virtually no US content” and alleging that a waiver issued under former president Barack Obama allowed Canada to bypass Buy American requirements. He also repeated longstanding grievances over Canadian dairy tariffs, provincial restrictions on US alcohol sales and Ottawa’s outreach to China.
The new six-lane crossing is expected to open early this year following final testing and inspections, and will become one of the busiest trade links between the two countries. The bridge, which began construction in 2018, is projected to cost about $6.4 billion, up from an original estimate of $5.7 billion.
According to the Canadian government, the bridge has been fully funded by Ottawa but will be publicly owned by Canada and the state of Michigan. Windsor Mayor Drew Dilkens said parts of the US president’s post were “just insane,” insisting that US steel was used on the Michigan side of the project.
Trump endorsed the bridge during his first term, calling it a “vital economic link,” despite lobbying from the owners of the Ambassador Bridge, who have long opposed the project.
The new threat comes amid broader strains in US–Canada relations. In recent weeks, Trump has also warned of steep tariffs on Canadian-made aircraft and suggested punitive measures if Ottawa deepens trade ties with Beijing.
Canadian Prime Minister Mark Carney has rejected claims that Canada is pursuing a free-trade deal with China and has urged Washington to respect Canadian sovereignty.
