What I can say is that we haven't undertaken a study or an analysis of the potential increase in drug costs. My limited understanding is that there are other agreements that also have an impact on what would happen directly out of the TPP, including CETA. I think some of those issues are still outstanding. There's a common view, though, that those drug costs could increase.
Today we think drug costs in Canada are already too high. We're participating in the Patented Medicine Prices Review Board and undergoing a modernization consultation right now. I think there are a lot of issues that make drug costs high, and in this case we haven't done an analysis linking it to the TPP, because of the other implications there. There may be other witnesses who are better able to answer the drug cost question.
