I guess there are several reasons for the increase in the number of cases. I think that, over the last few years, Canadians have become more interested in the environment, especially last year, when the Copenhagen Conference, among others, was held.
I think that people are more interested in environmental issues. I don't know how this shift has affected other departments, but I assume that they have all experienced a fairly similar increase in demand. We have certainly noted an increase over the last few years.
Could you give us a reason or two for this shift, Mr. Bernier?
