Thank you, Mr. Chair.
You mentioned that prevention is probably one of the best ways we can deal with aquatic invasive species possibly entering Canadian waters. I'm wondering if you could expand on what some of the best ways are. We've heard some. Do you have other specifics in terms of prevention? Your presentation here talks about risk assessment, but I'm looking for some specific steps.
I'm thinking also specifically in relation to your comments about your work with Transport Canada. You mentioned you work cooperatively with the department, but does that mean it takes the lead and its mandate dominates, or does DFO have the ability to, for instance, say that you have to deal with ballast water, and that's an issue, and you need to go beyond...? Whose mandate trumps?
