That has been part of the discussions with the U.S. Again, it's just one of the options we're looking at. At this stage of the game, we're trying to work through the specific issues we have on the border. I think we've been very successful in doing that over the last couple of years.
There does seem to be an adaptation by business to the changes that have taken place along the border. Wait times are improving. Both governments are putting much more money into infrastructure at the border.
We are concerned about how things will proceed with the passport deadline in June. But again, I think we have established a very strong working relationship with the U.S. in trying to work through each of these issues as they come up.
The perimeter is certainly an option, and it is being looked at, but it has complexities to it, as you can well imagine.
