Certainly. As my colleague noted earlier, we have a number of measures that serve to protect Canadian interests as related to the import of products to Canada that could bring with them pests or diseases. The regulatory framework under the Health of Animals Act prescribes a number of diseases on which Canada places restrictions in terms of the entry of products. The plant health act does the same. Listing individual measures would be lengthy, but suffice it to say that the regulatory framework in terms of the control of imports of food, agricultural products, and beyond serves to provide those protections.
I'll use one example in the plant health context that most people would not anticipate, which is that in returning to Canada as a hiker, if you have dirty boots with soil on them—soil is a significant vehicle of plant pests—our regulatory requirements could then result in those boots having to be decontaminated before they could enter Canada. The examples go from as simple as that one to a shipment of grain coming to Canada with us seeking the assurance through export certification that a number of plant pests are not present before the shipment is offered entry to Canada.
