I thought that in the categorization process, because it was science-based, there was science there that you had to make some determination that it met the criteria, which are persistent, bioaccumulative, inherently toxic, or there was potential for human exposure. So there is science to make a determination of the 23,000, and the result is we have 4,000 that require further assessment.
Again, the government set the parameters of the science that would be involved in that program. It will be involved in setting the science and the parameters of what science will need to be part of the second phase, the screening phase. I think it's a bit misleading to say there isn't evidence out there, because the government is going to be looking at a wide range of data. While they look at other jurisdictions, they can also use other programs that are in place. For example, I mention the high volume program that they'll be looking at.
As well, if there is a data gap or it appears there is a data gap, before a determination can be made about that substance being continued to be used in Canada, industry will be challenged to provide that data to the government for the government to make their assessment and determine if that substance can continue to be used.
