What I can say is that the authority that the lobbyists commissioner is given in Quebec is the authority of an investigations commissioner. That authority makes it possible to find all the evidence necessary, which isn't always easy to obtain.
You just spoke about the concept of "significant part". It's one of the major reasons that makes it difficult to comply with the act. Every piece of legislation that has been adopted in Canada has in part copied what existed. In my opinion, that explains some of the problem.
As for the authority to investigate, it's important that we be able to go and see public office holders and that they be required to provide the information required so that we can conduct an inquirty. It's also important to be able to go and get the lobbyists' side of things, when the time comes, if explanations are required.
The lobbyists commissioner is best suited to get to the bottom of things because it is his responsibility to ensure that the act is respected and because he administers that specific act. He knows all the ins and outs of it. He's the one who can go the furthest in finding the truth.
Since the purpose of the act is to enable the public to know what has happened, in other words, making the activities of lobbyists transparent, I firmly believe that the commissioner must have all the authority to obtain all the information needed to be able to report to Parliament, to the National Assembly or to the provincial legislative assemblies.
