We're from the U.S. and my husband claimed his residency in Canada and flew back to the U.S. Does he need a travel document for when we drive to Canada to move?
When you drive to Canada, you need nothing more than you already have. The certificate of permanent residency proves he's a PR, and can be used at the land border.
If you fly to Canada, unusually, you need nothing more than you already have. US citizens can fly to Canada on a US passport with no eTA, and the COPR then proves he's a PR and will allow him in at the border.
Other nationalities would need additional paperwork to fly in, because they need an eTA to board the plane, and PRs cannot get an eTA. This means the only way for them to get on the plane is a PR card (the COPR is not adequate proof). So you might see advice that that is needed, but because you're an American/Canadian couple, it doesn't apply to you.
