Yes. So as we do an assessment, we'll say we do not like a substance, or we do but we would never want to see it above this level. This program of bio-monitoring will then allow us to track progress. So risk assessments will set those levels and will allow us to move forward.
With respect to the pace, the other thing I should point out is that Canada is the only country in the world at this point in time that has been able to come forward, as far as I know, with a plan to the meet the SAICM commitment, which is the Strategic Approach to International Chemicals Management. We'll be done well ahead of the international deadline, which is 2020. They view it as a very long-term approach, and we're moving very aggressively. This committee has asked in the past how many assessments we've done since CEPA 1988. There have been about 500 substances. We're going to be moving that much through very quickly, as I've just pointed out.
