I can't answer for the operational commanders in Canada Command, but I'm sure they'll have some suggestions.
At the strategic level in Ottawa, for example, a number of interdepartmental committees deal with the Arctic on a weekly or monthly basis at both the ADM and DM levels. So there is information sharing. I've been working on the Arctic files for about seven or eight years now, and a lot of progress has been made. So right now it's working fairly well at the strategic level.
