Thanks, Mr. Chair.
Thanks to all of you for travelling the long distance to be with us. It's much more convenient for us to see you when you come to us, but it would be great to go and visit the Northwest Territories. It's the only part of Canada I haven't been to yet, but I have seen the presentation on the highway design and the protection of the permafrost layer. Knowing what has happened over the last 30 years, there have been some drastic changes. Could you comment a little bit on the risk we face, and the need for science to be on top of this?
