Let me first just add something on the geographical links.
Limiting it to flights that depart Canada would make sense if every other country in the world had equivalent protection. The European Union does, but there are a hundred other countries that do not have equal levels of protection or do not have any protection.
By doing that, we then exclude a number of people from any kind of protection. I think it's very important, and again the devil is going to be in the details to figure out how we're going to operate it, but there is really no uniformity across the world.
To your actual question, I think the European Union directive is a good start. It is not fully transferable to Canada, and we ought to be careful about importing things that work in one jurisdiction to other jurisdictions, but I think they have spent much more time thinking about this than we have, and we can learn certainly from their successes but also from their mistakes.
