Yes. That is a terrific question, and it's one of two that I was going to suggest the committee should really think about, the other being the involvement of the Ethics Commissioner beyond simply setting up a recusal regime and continuing on.
On the question of whether or not an official should be able to affect their interests if those interests are not disproportionate or are a part of a broad class, that idea comes from American legislative ethics. The idea is that if you're a legislator and you're voting on legislation that's going to affect many people and not just you, and there are 400 other members of the legislature who are involved in the decision and it's not yours alone, then it's okay for you to participate, because you're being countered by others.
It's been imported in Canada, into our ethics regime for the executive branch, and I'm not sure it's legitimate to do that, but there is a push-back, which is that if the Prime Minister can't even deal with broad issues that affect his interests coequally with others, then we're getting into a situation where the Prime Minister is not able to really act in office.
I've heard it said that the Prime Minister should simply liquidate his assets totally and put them in GICs or cash, but even then, of course, he can affect his own interests, because he can affect in various ways the interest rate, etc.
Some thought has to be given to where—from really disproportionately affecting your own interest to even affecting your own GICs—we should draw the line as to what constitutes a conflict of interest. That's an important question. It's a philosophical question that I think the committee should wrestle with.
