Honourable member Bennett, the public health community is a small one. I know Dr. Schabas, and I know all the others. They're all my colleagues. I'm part of that community.
From the consultations and practical interactions we've had with our colleagues in the United States and other countries, public health officials responsible for their respective quarantine acts or equivalent in terms of control measures at the border, there is consensus, among the people I've spoken to, that from a risk management point of view, it's not practical, as you say, to look at the land conveyance issue but to focus on air and watercraft. That's why we're proceeding in this fashion.
In a sense, that's reflected in terms of the results of the revision of the International Health Regulations. Among the many people involved in those negotiations in Geneva, you obviously had official diplomats and so on. But underneath those people, the people who actually provided the practical advice were the public health officials from each of those countries--including me, for Canada. So we all came to the same place, at the end of the day, in terms of how we should be coordinating and collaborating in terms of control of infectious diseases.
So in terms of measures at respective borders, in terms of what is good risk management for how to deal with cases that are identified prior to arrival in Canada, this is the end result.
