America Rewrites The Agreements It Signs
The Gordie Howe International Bridge was financed and built by Canada under a bilateral agreement, yet Washington threatened to block its opening and extracted new concessions—an episode that has become a symbol of how little signed commitments may mean under Donald Trump.
Canada paid for the new bridge linking Windsor and Detroit, accepted the construction risk and entered the project under a 2012 agreement designed to preserve a vital continental trade corridor. But as the opening approached, President Trump threatened to prevent it, demanded changes involving tolls and American influence, and then imposed fresh 50% tariffs on a range of Canadian goods. The joint celebration was cancelled, leaving Canada to mark the opening alone while both governments returned to another round of trade talks.
The dispute matters beyond one bridge. USMCA itself is now under strain as Washington negotiates separately with Canada and Mexico and uses tariffs to seek concessions outside the normal treaty process. Agreements are supposed to make commerce predictable and protect smaller partners from raw power. When the stronger party can reopen settled terms whenever leverage appears, cooperation becomes provisional, investment becomes riskier and allies begin looking for alternatives to dependence on the United States.
