More and more of my (Canadian) friends and family have made the decision to cancel discretionary trips to and through the USA in recent months.
Most people I know who are are staying away aren't doing it because of Trump's EOs or new rules that are coming. The majority are caucasian Canadian citizens, so they'd breeze right in anyway.
It's more that many Canadians that I've talked to feel that discretionary travel to the US is tacit support for Trump and his Republicans. We realize it's a drop in the ocean, but it's the only tool we have.
My wife and her friends recently cancelled a 'girl's weekend' in Seattle. I have a cousin who recently made the decision to go to Cuba in May instead of the Hawaii trip she had planned. Other friends who cancelled a Disney trip. Still others who cancelled San Diego and went to Mexico.
I also know of several people here in Vancouver who booked trips to points south and east and specifically avoided (cheaper) US carriers so they could avoid transiting the USA. They instead transited YYZ, YUL and MEX.
None of these people are radical eco-hippie-lefties. Just average Canadians who have made the decision not the travel to or through the USA.
I know, I know, anecdotal, we don't need you socialist commie Canadians anyway, Trump rules, America's great, don't let the door hit us on the way out, blah blah blah, but nevertheless that's tens of thousands of dollars deflected away from the USA right there in my little sphere, within the last month or two.
