Madam Chair, I think the issue might be better answered or supplemented by a comment by Mr. Dufresne because, in fact, it's a legal question in the main.
From my point of view, I would be tempted to say that, from looking at what they do at Westminster, you admit that you have maybe an interest, basically because of a prior career that you had before you were elected a member. You simply say that you want everybody to know that you were formerly the head of a company or the head of a union of one kind or another, so they can at least understand the framework that might inspire your comments, and this is where I think Mr. Dufresne would be more helpful.
The idea of reporting your income streams is a private issue between you and the commissioner. It is not something that is, in fact, public knowledge.
