First of all, it actually occurs at all three levels of government. There are agreements in place and, on occasion, exercises and real-life scenarios in border communities. For example, Windsor and Detroit have MOUs in place and are able to move reasonably seamlessly across the border, and the federal government can play a role in ensuring that. They can also offer mutual aid and share resources. It may be much quicker to bring in a local bordering municipality. They are planning together, exercising together, and thinking about these things.
Many of the provinces, including Ontario, Quebec, and the maritime provinces, have been meeting as groups of provinces and putting in place MOUs for mutual assistance in the event of natural or man-made events that would affect both and working out how to do that. We have seen it actually happen during power blackouts, for example. Hydro crews move back and forth. There are very detailed MOUs in place that allow them to be licensed and to move into various areas. Dealing with forest fires is another area--Canadian crews go south and American crews come north.
At the federal level, we obviously are working with the Department of Homeland Security and building relationships as well and trying to improve on our ability to mobilize quickly and to have the American people understand that we sometimes possess expertise that can assist them and they in turn us.
During SARS, one issue we had was that there were some very detailed investigations we needed to do in a particular case of SARS. We called CDC. CDC from Atlanta sent a team that worked with the federal people and the provincial people. The three levels formed a team and wrote a joint report.
That exists, and we take advantage of it. I think since 9/11 it has actually been strengthening.
