The National Post reports in its Wednesday edition that border crossings from Canada into the United States dropped by nearly a million travellers in March compared with the same month last year. The Post's Adrian Humphreys writes that the latest data from U.S. Customs released Monday says 4,105,516 travellers were logged crossing into the U.S. through its northern border with Canada last month by air and land, which is a drop of 864,844 travellers from March 2024 when 4,970,360 travellers were logged. That is a decrease of 17.4 per cent. Cross-border travel from Canada into the United States was soaring at the end of 2024, shaking off the reduced travel after the COVID-19 pandemic. Through October, November, December and January, there were more U.S.-bound travellers year-over-year since 2022, when pandemic travel restrictions ended. U.S. President Donald Trump started taunting Canada and threatening broad tariffs and even annexation in January. Last week, Statistics Canada said the number of Canadians returning from the U.S. by car was down almost 32 per cent compared with March, 2024, the third consecutive month of year-over-year declines. Return trips from the U.S. by air were down 13.5 per cent in the same periods.
