California tourism could lose billions of dollars because of President Donald Trump's policies on tariffs, immigration, and gender identity, as well as his talk of annexing Canada.

"Canada, the second largest source of international tourism dollars for the state after Mexico, accounted for $3.7 billion of the $26.5 billion foreign travel brought into the state last year," said Visit California, a tourism non-profit.

It could be a big problem for California that many Canadians are angry about tariffs and Trump's insistence that their country should become the 51st US state.

Many are refusing to buy US-made products and don't want to cross the border.

Canada and other countries have also issued advisories for travel to the United States, warning travelers that they risk being detained.

Charlie Angus, a member of Canada's parliament, recently called Trump's rhetoric an act of war and urged Canadians not to travel to the United States.

Anna Kelly, a White House spokesperson, doubled down on Trump's annexation comments in an email response to CalMatters' questions about the decline in international travel, especially from Canada.

California saw an 8.8% year-over-year decline in international arrivals in February.

Visit California said, "If that continues, a broad travel slowdown could hurt different industries that fall under the tourism umbrella, including hospitality and restaurants, and the roughly 3 million Californians who work in them.

"Tourists spent $34.8 billion at the state's restaurants in 2023, more than the $32.8 billion they spent on lodging," Visit California said.
