Yes.
We think, but we're not sure, that ballast water is not going to be a problem going forward. We need to test that to make sure that that's the case. Hull fouling is an issue, particularly on the two coasts. We don't think it's a problem in the Great Lakes.
The live trade is another area that I think is emerging as a dominant problem. There are a lot of species—both animal and plant—that are sold in pet stores around the country that could pose significant problems for the systems if they were to get out.
I know that in Ontario we have a case where at the same time as people are free to sell plants on the Internet, the Ontario government is conducting an eradication program. Somewhere along the line, the federal government.... Of course, before you can ban a species, you have to do a risk assessment, and it's the federal government that would do these risk assessments. We've done them for Asian carp and for some other species. The federal government would be asked by the provincial government or by the citizens: “We want to protect our resource. Please do a risk assessment to determine if it can get here and if it will cause harm if it gets here.” If the answer to both of those questions is yes, then the provinces should be acting. Ideally, they're going to act in concert with the federal government—DFO in this case.
