Indeed, a regrettable substitution is an area that has been a concern of government officials, industry and all Canadians, I would say. An approach moving forward is that a chemical assessment is being done from more of a class-based approach that understands similar chemistry, a similar mode of action and similar uses to be able to identify which of those may be a concern and which of those may not. That would give predictability to industry on the chemistries there are concerns about from an environmental or human health perspective and those about which there are not concerns.
There's also a new mechanism under the Canadian Environmental Protection Act called a watch list that lists chemicals for which there may be concerns from a health and environmental perspective. That is a communication mechanism for industry and Canadians to stay away from that chemistry, recognizing the concerns we have. That's a basis upon which investments in alternatives can be made that would not be in areas of concern identified by the government.
