I guess anything that makes labour or capital or services flow more freely across borders is always a good thing. I think all you have to do when you do that is just make sure you have the right standards. What can often happen when you break down various trade barriers is that you get a race to the bottom in terms of standards. So you just have to make sure you have the appropriate standards.
For us that's not a particular issue, because CAs have the same standard across Canada. But in certain areas, you really just have to make sure you have the right standards.
