I think there have been very different types of initiatives. They're hard to compare in many ways, because different departments and agencies are engaging in different functions. I wouldn't necessarily point to one as being the best.
Treasury Board has been leading the open government movement within the government, so that's a good place to look. I would encourage you to call someone from Treasury Board to maybe talk about the transparency initiatives, the Open Government Partnership, and of course how it relates to the access to information system as well.
Access to information was included in some of the early open government work engaged in by the Government of Canada in the context of the Open Government Partnership, and then it kind of fell out of place in the open government action plans.
I know I'm moving away from your question. However, I think it's quite subjective and a bit more nuanced to say that someone is doing a lot better, or one agency or department is doing much better, than the others. They each have their own very different initiatives.
