Thank you for the question. I'll begin the answer, and then perhaps my colleagues will want to add some details.
But there is absolutely a need for ongoing studies to understand the long-term impacts. It's one of the reasons that we believe the biomonitoring program that has been started is so key, because now we can actually, with the assistance of working with Statistics Canada, which has significant expertise in statistical analysis and monitoring.... Canadians have proven to be quite willing to come forward and be part of these biomonitoring samples where we actually take blood levels and other samples that we can test and thus look in the long term at exposure. So I think we have a very new and quite important mechanism on an ongoing basis.
