Thank you very much for the question.
We certainly share the view that this is an important emerging issue. As has been noted, this is an issue that has emerged relatively recently. Our scientists are aware of it. We've been in discussions with the U.S. EPA, for example. As they are doing research, we want to be linked to it so we are in touch with them.
As was noted earlier, we try wherever we can to work in partnership with other countries. If any one of us discovers something new, an emergent issue, we will work on it. It's also an issue that we will monitor as the science develops.
But even while it's in the developmental stage, we will make our colleagues in the provinces and territories aware. Because there may be occupational health and safety guidance they would want to follow up on even while the science is developmental.
So this is an issue we are monitoring internationally, and if the science that we discover, or that our partners discover in concert with us...we share this information. If we have new information that additional action is warranted, then we will certainly take it.
