A recent study by researchers at the University of Toronto has revealed a 42% decline in Canadian visits to major US metropolitan areas during the second Trump administration, significantly exceeding the 25% drop indicated by official border-crossing data. This decline is affecting economies in US border towns that depend on Canadian visitors, as many Canadians reconsider traveling to the US due to immigration enforcement and tariffs imposed by former President Donald Trump. The research highlights notable decreases in visits to popular destinations such as Las Vegas, Walt Disney World, and winter recreation areas in Florida, which are traditionally favored by Canadian tourists. The study analyzed cell phone data from Canadian devices traveling to US metro areas between April 1, 2024, and March 31, 2026, revealing that the decline also encompasses business-related travel and return migration of Canadians previously residing in the US. The findings suggest broader economic uncertainties are influencing travel preferences, particularly in high-tech and financial centers like San Francisco and Houston.
