If I might supplement, Mr. Chair, there are a number of factors that go into this: severity of disease, the number of people relative to what you might normally expect, and how broad it is. There are quite a number of factors, and it's a scaled response.
What many people don't realize is that at the very same time as we were dealing with this listeria outbreak, we had another listeria outbreak going on in Quebec related to cheese, as well as some 20-plus other outbreaks and events we were tracking, following, working on, paying attention to, and being involved with. It's not as if we only have one thing to do or one outbreak to deal with at a time. We're constantly monitoring the world. We're constantly engaged with our partners around the world and in Canada. Some we are more heavily involved with than others.
Again, those are some of the factors that determine our level of engagement. Clearly, when a province says it needs our help, that is one of the jobs we fulfill as well.
