Very briefly, perhaps on a slightly different tack, because of the way this discussion has evolved, I have some points I think are relevant. Dr. Khatter raised this, and I want to come back to it, as it's very relevant to this discussion.
First and foremost, it's important to recognize there is not a silver bullet in all this. If we demanded information from industry, as we do now, the departments still have an obligation to assess that, to determine if we can replicate that, if it's sound, if it's repeatable, and then work to draw a conclusion. When you take a look at how we receive that data, we have to validate it, make sure it is done according to standards, and replicate it.
The other point in all of this is that the science is evolving, so to ask for information on things like mixtures, cumulative effects, those are areas where we are concerned, but the science and its ability to answer that are still evolving. Some of these are areas where more research is needed--not just in Canada, but internationally--and there is an understanding of that.
If you take a look at the 23,000 chemicals, the number of potential mixtures, the number of ingredients that go into any one product, you could keep both departments busy for a long, long time on just one substance.
