There's a difference between who should do it and who should pay for it. Actually, what we've seen things evolving into is that regulatory authorities set up departments of risk management where they negotiate the plan with the companies very early on and then they agree that such a study needs to be done.
There has to be monitoring of how the study is done because we have to ensure that high-quality data will be generated. What we've seen and what could be very applicable in Canada is to create a network of centres for excellence in, for example, pharmaco-epidemiology or observational studies. I think this is already on the map. Certainly the studies could be conducted through that network and funded by the companies, and we've seen that this model is actually taking place in both the U.S. and the EU.
