If a US citizen, who works for a US company, often needs to visit Canada for work, is a work permit required ?
My husband is a US citizen, and we live and work in the US. He often has to go to Canada for business (to service contractors who buy his product). Technically, he is not doing any “paid” work in Canada but last time he crossed the border the Canadian border patrol told him next time he will need a work permit. Anybody knows what kind of permit they were talking about?
