I'll just answer it briefly, Mr. Chair.
For the Food and Drugs Act sector, a lot of the substances that have been on schedule 1 and are of concern to us, for example ammonia, aren't toxic. So we continue to use it in our products because it's not toxic in glass cleaner, for example. It's toxic in waste water effluent.
With respect to other substances that we may know going under risk assessments, companies try to provide the best science that's available to Health Canada and Environment Canada during their review processes. But if there is a time when a substance may become CEPA toxic in consumer products, of course the companies would reformulate and take that into consideration.
