I think my main concern is not the border services but airport workers. I was at the airport recently and there were people in my line just in front of me traveling to Canada. I didn’t hear much but they had some issues with an airport worker even though it seemed they had everything prepared for the trip.Unfortunately that's just the terminology they use - because (in theory) they can choose otherwise at the border. In practice for those that truthfully meet the criteria, it's really rare they decide otherwise at border.
