What I have found in my experience talking about the Lobbying Act is that Canada is considered to have quite a robust regime model when it comes to lobbying. In fact, in terms of designated public office holders, they now report on a monthly basis if it's oral and arranged. In my experience, when I was in the United States, they're looking at the 20% rule. It actually applies to consultant lobbyists. When we're looking at why we have lobbying legislation and transparency, it makes sense that there is no 20% rule in Canada applying to consultant lobbyists.
