I'm going to give you my personal opinion and then my professional opinion. Personally, I disagree with the Harper decision, so I would agree with the Chief Electoral Officer that we should have absolute freedom of expression. I don't like those kinds of limitations, but that's not the law. I have to live with the law, and so does Parliament.
Harper and all of the cases following Harper make it clear that you may limit third parties and that you may require all donations to be identified. There is no precedent I am aware of that would suggest that there are some individuals who get to make secret donations and don't have to disclose those because of the charter. That's just not the law.
