There is a precedent here in Quebec. I have a document about a program they put in place for the trucking industry. Claude, and I think David, talked about the accelerated CCA for the newer trucks, along with the LNG, but in addition to that, they put in place a program in 2009 directed at the introduction of new technologies to reduce fuel consumption, and by extension greenhouse gases.
You were asking about numbers. In the Quebec program, they will rebate 30%, up to $3,000, for an auxiliary power unit. Side skirts make up another category—it's 30%, up to $1,500. The program is sunsetted. It doesn't last forever; it expires in 2013. The total cost of the program is $27 million for the trucking industry. That's an example of the sorts of things that could be done.
