Thank you for the question.
I concur with you that industry likes certainty and schedules are helpful. When I said that 2020 would be a good goal, it was really in the context of completing the full categorized list that requires screening assessments. Within that timeframe it should be left up to Environment Canada and Health Canada to set the schedule for how those assessments should best be meted out.
From our understanding in talking with Environment Canada and Health Canada, we're expecting that very soon we'll see a schedule that delineates how these substances will be prioritized and meted out. From the latest conversation, we're expecting to see a scheduling of 15 substances every six months. That will help us schedule how we're presenting our information, preparing it, and assembling it, whether it's from our own companies in Canada or from international portions of our companies overseas. But you're right that there is a need for a schedule. Industry is very anxious to see that schedule and understand what is going to be demanded of us and when.
Putting a timeframe on each individual assessment is not realistic because, as I said in my comments, these will be highly variable. Some substances will require a lot of assessment and others will be quick to be completed, so I don't think that setting a timeframe on that basis will really be helpful. Having an overall timeframe for completing the full job could be of value, similar to what was happening in the categorization process. That's as much help as could be needed, from a political will standpoint.
