The other aspect is that conceptually, as a previous question alluded to, public health authorities were all on board, in terms of the previous Quarantine Act. I think the question comes to the practical application--for example, even the technical problem with the wording: the operators of conveyances are obligated to report to the nearest point of entry. Those were things that we didn't recognize in a practical sense, until we got into the practical implementation.
Things have advanced. As has been alluded to several times, when we had the discussion and the negotiations for the revised International Health Regulations, this was certainly a part of the discussion among all member states of the WHO. Because of the same types of issues we're discussing here, from a practical risk management point of view it made sense. Therefore the internationally accepted standard is not a decrease in coverage; it's really that the appropriate and necessary application of risk management applies to air and marine. So in Canada, we're not doing more or less; we're basically being consistent with what's being done around the world.
