There was a question asked earlier about why we aren't pushing ahead with cargo pre-clearance now. Besides the fact that the agreement isn't in force yet, the other issue is, of course, that we have to learn how to do cargo pre-clearance. We don't have the decades of experience that we have with traveller pre-clearance. We have to learn how to secure loads. We have to learn how to make sure that we've done the necessary checks but haven't gone overboard, hence the importance of continuing to do pilots and of identifying new cargo pilots that build on the Pacific Highway and the Peace Bridge pilots that were done before.
We still have things to work out and to figure out. I think that once we've been through a round of those cargo pre-clearance pilots, we'll have a much better idea of, first, the economic opportunities and, second, what the actual costs of establishing cargo pre-clearance are.
