U.S. border guards have recently issued several five-year bans to Canadians at border crossings.
Canadian traveller Rochelle Trepanier was detained at the Peace Arch border after being turned away in Port Angeles, where border guards had asked for proof of her ties in Canada. Despite providing several documents that proved she lived in Calgary, she was questioned at the Peace Arch border and issued a five-year ban against visiting the U.S.
The bans have been handed out more frequently as of late, particularly to Canadians who don’t have steady, full-time work or who don’t own a home. Border guards can issue them at their discretion, and there’s no appeal process.
