I'll turn to Bill to respond to part of that, but let me just deal with the question here about when this issue started. If you actually trace back the migration patterns of when people started to move toward the Canadian border, it in fact predates the last election in the United States. The beginnings of that movement were before the government changed in the U.S.
Therefore, I don't think you can say entirely that what is happening is a phenomenon triggered by political developments in the U.S., because the origins of this began before that.
Our agencies, all of them at this table, coordinated by the government operations centre, learned many best practices and many practical lessons from the experience of last year and applied those lessons to our planning process for this year and for future years, as necessary. We've engaged multiple departments of the Government of Canada, together with provinces and municipalities, as well as NGOs. A number of NGOs are engaged in this, like the Red Cross, for example, to make sure that we have the provisions in place and the flexibilities to deal with the eventualities as they present themselves. We may need to increase; we may need to decrease.
As we saw earlier this year, there was a trend upward in the numbers until about Easter. There was a spike in the numbers around Easter, and ever since then the numbers have actually been going down to the point right now that they're at the lowest level they've been all year.
