As Canada responds to Trump’s moves with emergency interventions and “buy local” boosterism, significantly fewer Canadians are crossing the border for once-ordinary activities: shopping, eating, fueling vehicles, vacationing or visiting family and friends.

The Sault area lost at least $82.9 million last year in local spending because of decreased crossings, according to an estimate from the International Bridge Administration, which manages the span: $62.7 million on the Michigan side and $20.2 million on the Ontario side.
