Canada will maintain those international linkages—not Environment Canada, though. This would fall to my colleagues in the federal government. There is something called the International Plant Protection Convention, and within that there is a mechanism called the North American Plant Protection Convention Organization, where risk assessments are done on plants that could be invasive. That's one mechanism. The second mechanism is the World Trade Organization agreement on what the Canadian Food Inspection Agency refers to as sanitary and phytosanitary measures. For example, shipments of seed should not have seeds of potentially invasive plants mixed in with other seeds such as wheat or oats. There are a couple of mechanisms internationally that focus on invasive alien species.
I don't know if there's anything additional from my colleague from Natural Resources Canada.
