One of the responses of Fisheries and Oceans to the Auditor General's audit was the creation of a centre called CEARA, the Centre of Expertise for Aquatic Risk Assessment, and it's based in Burlington, Ontario. Before you can ban the sale of these organisms.... This is trade, and so the government could, in fact, be sued by the vendors, if the vendors initially selling these are, say, somewhere in the United States or some other part of the world. They could say that their business had been harmed. Before we can do that, the World Trade Organization has rules that governments must play by if they want to ban live sale of organisms.
One of the things you must do is a formal risk assessment. DFO has this centre and they will do the formal risk assessments as they've done with snakeheads and with Asian carp species. After those ecological risk assessments are done, if the answer is that they could survive in Canada and that they would harm Canada if they were introduced—you have to have a yes to both of those questions—then the government is legally entitled to ban live sale of that organism in the country. That's when Ontario then brought in legislation to ban possession of live Asian carp in Ontario. So, you'd have to do this with these plants as well.
