Over the last two or three years, we've heard about individual findings in Toronto Harbour, in the Sandusky River system, in Lake Erie or just out of Lake Erie, so we have done a risk assessment. We did a risk assessment for bighead carp and for silver carp a few years ago. We've just completed a risk assessment for grass carp. There are four types of Asian carp. They're all a challenge. Maybe the least of the challenge are the grass carp, but they're still a challenge. They're voracious. They eat a lot of algae, etc.
The finding is—as I understand it and I ask Arran to correct me if I'm wrong—that it's not established, but has arrived. We have an Asian carp program that does early detection. We seek to remove them as quickly as we can. We work with the U.S. on it. Part of the challenge is that most of the findings are on the U.S. side, not on the Canadian side. We think the ones on the Canadian side, for the most part, come from the live food trade. On the U.S. side, we're less certain about that.
We are working with stakeholders. We're talking to Ontario. We're talking to stakeholders. We're assessing the new science, and we are maybe entering a new phase in terms of that.
