This isn't an area I'm an expert in, but I would make two comments.
First, as best as I understand it--and certainly I don't have any problem with those seven countries, although I can't rhyme them off to you--the legislation says the price in Canada can't be higher than the median price of those seven countries. So I guess my first question would be how the prices in those other countries are set. It seems to be what the market will bear, not much relation to what the benefits of the drug are.
Second, my understanding is that Canadian prices are compared to the list price. France, for example, enters into all sorts of volume price agreements. The list price might be the price they'll pay for the first 500,000 people for the drug and they'll pay a much lower price for the next 250,000, just for an example. We're comparing our price with the list price of those drugs for those countries when in fact the actual prices that are paid might be lower.
There are others who are much more expert in international drug pricing than I am.
