Madam Chair, there is no jurisdiction that yet has the tool to deal with all the potential mixtures. We continue to assess individual substances. We can look at the cumulative exposures of that substance through all its potential uses, but when you look at mixtures in one product and another product and how they all come together, there is new science that is required to be able to do that. We think we're close to that, but we're not there yet—Canada or any other jurisdiction.
