There is indeed a great deal of energy going into this issue. I'd be remiss if I didn't pass on the minister's thanks to this committee for the focus you've put on it and the personal time and attention you've paid to it. That has made a difference with the European parliamentarians, among others. He's very grateful for that.
On the specific issue you raise, there have been meetings as recently as this week. In fairness to Foreign Affairs, I think they are fully engaged. Certainly Ambassador Sullivan has been very heavily engaged. The Premier of Nunavut has been engaged and met with the minister. Adding that presence to some of the recent trips to Europe was extremely useful. But the minister shares your concerns that we need to keep working on this, because it's not an easy issue. We're not necessarily up against scientific facts; we're up against perceptions, or whatever.
Kevin, you might want to say something.
