The Health Canada standard, which was established a long time ago, has been revised. In the last few years, there have been other revisions. There have been reports, such as the “Final Human Health State of the Science Report on Lead”, which has new scientific data that we have used. We made a new recommendation and published it for public consultation in the past year. We are in the process of finalizing it with the provinces. So there should be a new recommendation for drinking water quality in Canada. It should be available by about next year.
