I don't know whether I would position it as barriers. Certainly, standards are one thing we need to look at, interprovincial standards. As I said in the presentation to the FINA committee, we need to look at these standards. There needs to be harmonization between the U.S. and Canada. That's very important. Certainly, as you look at public transit and at the actual capital, it needs to be seamless with the U.S.
The other element to this is certainly in regard to looking at some of the programs that come out. If you look at the eco-programs, I would ask any member to find the reference to natural gas on the transportation side—I didn't see it—as alternative fuel. So in terms of some of the programs that are already there, we need to reference that there are opportunities for natural gas.
