We're back at the question of the Prime Minister engaging in debates over legislation or regulation or policy that affects whole industries or the entire economy, and therefore also affects his own interests as a result. I'll go back to the observation that there are three remedies for conflict of interest: recusal, divestment and disclosure.
In some of the cases that you are talking about, he can't recuse himself, because he's the Prime Minister and he has to be involved in these issues. Maybe he can't divest himself, either; maybe the blind trust hasn't found a buyer for those interests. In those cases, disclosure is what we're talking about.
In fact, there is de facto disclosure. You just articulated it: The Prime Minister is involved in massive policy decisions that affect interests of his, as well as those of many other Canadians. As Canadians, you and I can judge whether we think the Prime Minister's judgment was biased, and we can weigh that in our vote at the ballot box and in our assessments of how he's doing.
In the absence of recusal and divestment, which may not work in this case, disclosure has to happen, but we sort of have it de facto.
