As the current commissioner, I administer two, one for public office-holders and one for members of the House of Commons. I don't see anything conceptually difficult about expanding to three. It does mean you have to be careful when you're asked for advice, because it means you have to differentiate, for example, between whether the person is a public office-holder, a member of the House, or a senator. That is not, however, enormously difficult to do. It's one of the reasons behind a decision we recently made operationally to try to assign each file that we get to the same adviser, in a sense, for life, so that they focus on that particular relationship and whether that person is a public office-holder, a member of the House, or a member of the Senate.
