“Since Donald Trump began his tariff threats against Canada and his ‘jokes’ about making Canada the 51st US state, I have not bought a single product originating in the US,” said Lynne Allardice, 78, a retired business owner from New Brunswick, Canada.

“Not a single lettuce leaf or piece of fruit. I have become an avid reader of labels and have adopted an ‘anywhere but the US’ policy when shopping. I will not visit the States while Trump remains in office, and most of the people I know have adopted the same policy.”

Acquaintances, Allardice added, were selling US holiday properties they had owned for many years.
