That's a good question.
As I said, things are becoming more complex. We have intelligence from abroad that we use, intelligence from other countries—for example, with a number of like-minded countries. We work very closely with the United States, with Australia, and with the European Union as well. We can't test everything, because we're the fifth-largest importer in the world as well as an exporter, but at the same time, we target products based on risk. We know from import controls what's coming in, and most cases in advance.
One of the things we've done is that in budget 2016 there was funding given to the CFIA to start looking at and working with industries and establishments in other countries. We are looking at and intercepting and having conversations about food products prior to them coming to Canada, as well as when they come to Canada.
