Thank you.
It is a national initiative, but there are a number of sites across the country. There are pilot sites at various points so we aren't just gathering information in one part of the country, for example. They are distributed across the country.
For example, we also have a program to work with first nations communities, because we know that we have some specific risks. We want to follow up and make sure that we can augment our information from the national study to understand whether there are specific risks in those communities.
We also know that, particularly with mercury, historically there have been some challenges for Inuit people because of some of the exposures in the Arctic. So we have a particular protocol called the northern contaminants program, in which we work with INAC and others in the community, with the territories, and with the aboriginal groups in the Arctic to make sure that we can have an ongoing mechanism to examine and look at that particular population, where we know from the research that there are specific issues.
