Well, I will be speaking to my own interests here. In Quebec, we decided to set up a mandatory system because the morning a health crisis erupts, we need to have all the information within an extremely short period of time. When we took the decision in Quebec to establish the current system, we didn't try to reinvent the wheel. When we first began discussing this issue in 1998, there had been many crises in Europe, if you remember, such as mad cow disease, foot and mouth disease and swine fever.
We organized a number of technical visits, during which we had the opportunity to meet with veterinarians and epidemiologists who had worked on these diseases and had tried to minimize their impact with the little information that they had. Once we had returned back home, they recommended to us that if we wanted to establish an efficient and effective system that would allow us to minimize the impact of such diseases and respond quickly, we should establish a mandatory system. We realize that this is a very tough requirement, but the morning that a crisis breaks out, the borders will be closed extremely quickly, and then it will be up to us to demonstrate that we can deal with the crisis. But if we don't have all the information we need, forget about it. And massive amounts of money will have to be spent to re-open these borders.
