It is a challenging question, because you have the data to look at history; you don't have the data of what could be if you were to get rid of the trade barriers. That's where you have to look at comparative advantages in terms of competitiveness and asking whether we could be more competitive in Canada in selling that product abroad, or maybe importing it because they are more competitive. That has to do with the aspect of comparative advantages. Their trade deficit doesn't help you; it's really getting into the micro-detail of comparing industry to industry in terms of the degree of competitiveness.
We did some work on the life sciences side; we're looking at biotech, for example. We spend a lot on life sciences in Canada, but we're such small players globally. There are other areas of biotech in which we spend very little, but we do have a comparative advantage. If we were to invest more in those other areas, such as bioenvironment or bioagriculture, we'd be much further ahead.
That's only a small example.
