Yes. Thank you for the question.
In a submission we did last week at the Standing Committee on Public Accounts, we talked about a chapter that we tabled in November 2009 on the federal government's management of toxic chemicals generally.
One of the areas in which we said there was significant progress—an important initiative with important progress—involved various programs at Heath Canada, in collaboration with other departments, including Statistics Canada and Environment Canada. It involved putting in place biomonitoring plans nationally in order to identify current levels of exposure for different toxins in the blood of Canadians, as well as, from that baseline information, then detecting changes. We've been very clear that this was an important and significant step.
