Madam Speaker, again the working assumption in the member's question is that this should be done unilaterally. Certainly that would be highly inadvisable, given our partner across the border. Again, these are discussions that need to be taken privately and soberly in a whole-of-government approach to how the border is managed. Hundreds of thousands of people cross that border regularly. We are lucky compared to our European partners to have only one partner across a border. People cannot simply march into Canada and march through Canada. We have three quasi-impermeable borders, and our partner in the major crossing of 9,000 kilometres is indeed a safe country, but issues do arise and we are addressing them in a sober and orderly fashion.
