This is again an excellent question and a hard one to answer.
On the first part—why we need to have international collaboration—it's that we have very smart people in Canada, but we are only a small proportion of the population of the rest of the world, and there are very smart people around the world. We can take advantage of their knowledge. By adding collaboration, typically on the research side, that helps very much.
Once you start the commercialization, things become a bit more complex, because then you may have both national security issues and also IP protection involved. We know that around the world there are different countries that are very aggressive in learning about what we're doing here in Canada, so we have to be sure that we are alert.
That's another thing I've learned in working in Canada. In fact, in working at a national lab in the U.S., security concerns definitely were something that was kind of up there. When I arrived here in Canada in 2000, there was very little, although I would like to thank people at CSIS and CSEC for their help in ensuring that what we do in Canada is protected in the right way.
