Mr. Poilievre, I mentioned at least three difficulties with that particular proposal.
One is the requirement for officers, which you in your question have acknowledged, and, I gather, agreed with, that makes that type of border enforcement rather impractical.
The second part of it is that if you have a border port of entry that is 9,000 kilometres long, you need to have, correspondingly, cooperation from the United States on the other side of the border—which they are, I think it's fair to say, not likely to do. You have no counterpart.
