We can. The issue is to always to watch what's happening, because science and technology are evolving, and industry is changing what chemicals we use.
One of the responsibilities of my branch is the chemical management plan. It's a very positive program. We are looking at the safety of chemicals before they are permitted to be used, which was not done before 1990s. I think it was CEPA in 1999 that instigated looking at chemicals before they were used.
You want to continue to monitor these things. We have had success in a number of areas, and the Montreal Protocol is clearly one of them. I talked about flame retardants as another one. We've also made a lot of progress with acid rain and acid-sensitive lakes in eastern Canada.
