The short answer is yes. We would use different words, but I think the concept is the same. The challenge function launched on Friday is about having industry likely do with new substances what we would like them to do with existing substances, which is demonstrate to Environment Canada and Health Canada that they can use that substance in a way that does not cause harm to the environment or to human health, and that will include all the ranges. So some industries might be able to demonstrate that they can do that and others might not. That will allow us to target our regulations more efficiently.
The second thing is that the only way we will get through categorization and the timelines that have been imposed is if we move away from a substance-by-substance approach to look at classes or categories of substances and the industries that use them. So we will be looking at industrial sectors and strategies as well as at classes of substances that have similar chemical properties, and we will try to deal with those in groupings.
