Thank you for the question.
As I indicated, late last year the Prime Minister announced a first-ever chemicals management plan, which was designed to deal.... We have a very strict regime right now on the addition of new chemicals in the environment, but there is a series of 20,000 legacy chemicals that had not gone through the same strict process. Canada was the first country to get through that list of 20,000 chemicals to decide which ones merit further investigation and which ones are safe for the environment. Of those 20,000, 4,300 of them were found to still be of concern, or we needed more information. Those are the ones that are subject to the reverse onus provision with industry, saying we need proof. They need to show us the scientific evidence that those chemicals can be found in our workplace or found in our kitchen or found in our backyard without having a negative impact on our health and safety.
We've already published a list of certain chemicals that have gone through the process. There will be another list of chemicals published soon, and we're just aggressively going through all these chemicals clump by clump, section by section, to identify which ones should be removed from the manufacturing process or removed from our living space. That will continue until we're done.
