I think you would have to speak to the office of the chief information officer, because they're the people who now, in my view, are most active.
On the list of witnesses, we've also suggested that you might want to hear from people at NRCan who are doing it and are producing very good data sets, as well as Environment Canada. These people will be able to tell you who the experts are, whom they've consulted, whom they're working with, and so on.
