Yes.
Canada's is one of the more developed mechanisms, and the work that's happening right now demonstrates how this ends up being developed. There have been many conversations about what this would actually look like; there's been a lot of engagement in this process. Some other countries, while they may have something that looks like implementing legislation, don't necessarily have implementing legislation that is workable or that is defined enough to be able to move forward.
Then I would go back to the question of political will. There is an enormous amount of political will, as demonstrated by all of us who are here today and the thousands of postcards that are here and the many others who have spoken out on this issue, all of which has pushed this forward in Canada in a way that it has not been pushed forward in other countries.
