Well, that would basically look at the success of the event itself: who it reached, how it reached, comments on how we could do better in the future, the impression of the people who participated, who they are going to take the information to, that kind of thing. That's the kind of evaluation we have.
If you're asking whether we have changed Canadian society, it's a little hard to do such an evaluation without looking at what else has gone on in the world over the last 15 years.
