A new research tool that tracks cell phone activity has found a 42% drop in visitors from Canada to big metropolitan areas in the US that is much higher than official border-crossing data, suggesting Canadians during the second Trump administration are avoiding US cities in particular.

Researchers from the University of Toronto said the tool showed a “year-over-year median decline of approximately 42% in Canadian visits to US metropolitan areas – significantly higher than official border-crossing data, which showed a roughly 25% decline”.
