Environment committee  Thank you very much for that question, because it's a very--

Environment committee  Oh, I see, the priority substances list.

Environment committee  Okay. The domestic substances list is all of those chemicals that are in trade in sufficient volume, and it's been added to over the years as things come through our new chemicals program. The toxic substances list is schedule 1 in CEPA, where the government has concluded that a

Environment committee  The domestic substances list. It was to take a look at the entire suite of those legacy substances in commerce to determine whether they met the categorization criteria as established in the act.

Environment committee  Yes, Mr. Chair, I can confirm that we have.

Environment committee  I did have a slight bit to add regarding your excellent question about how synergistic effects may be assessed. This is a very new and difficult area in the science of risk assessment, because it's often hard to understand all of the context for these interactive exposures. But o

Environment committee  Thank you very much for the question. The acceptance or refusal of a confidentiality request is a reviewable decision on the part of the minister and the exercise of the minister's discretion. There is communication between the government and the company claiming confidentiality

Environment committee  I suppose I should try to respond to that as well. Thank you very much for the question. Commercial confidentiality concerns do indeed have a huge impact on the useful exchange of information internationally among regulatory agencies. We try to overcome that problem by entering

Environment committee  She has asked me to provide a little bit of background information on the use of mask names in the context of the new substances program. Very often when a notifier brings forward a chemical for assessment, review, and entry into the market, there is a commercial context to tha

Environment committee  I'm afraid we don't have exact figures here today, but the kinds of resources that we've applied in my program to conduct that research have included a team of about a dozen individuals and also the development, in conjunction with Canadian academia and industry, of computer anal

Environment committee  I can get back to you on that very quickly.

Environment committee  Thank you, Mr. Chairman. My point was that it was assessed as a mixture. We didn't do sodium chloride or potassium chloride as unique constituents of that mixture, but we assessed the mixture of road salts themselves, of which potassium chloride is a small part.

Environment committee  Thank you very much, Mr. Chair. I have just one point of clarification. The risk assessment treated road salts as a kind of mixture, understanding that there were different chloride compounds included in the product, and did an assessment on that whole mixture, which did of cour

Environment committee  Perhaps I should explain a little bit about how that part of the act becomes operational within the new substances program. It happens whenever a risk assessor believes there is a reason for concern that isn't addressed adequately by the test information that has been received or

Environment committee  Thank you very much for that question, Mr. Godfrey. Obviously there are advantages in being able to gain access to test results and information on chemicals that are generated internationally. Canada's work in this area, to date, has been actually quite ambitious, to be able to
