In terms of the reach of this statute—and you mentioned something about shipping companies--I'm not entirely clear. Let me give what I think might be an answer based on what I think your question was about.
On the issue of what might be called the relationship of intent--how close, is it enough, do you have to intend to do things that are in breach of the voluntary principles--is it enough if you know there's a risk that you might come into violation? What happens if you are connected to somebody who's connected to somebody who might be violating them, and so on?
So those are issues that I think certainly warrant attention, and those are the sorts of things that typically in government legislation of this sort remain to be worked out, both through the level of regulation, through the Governor in Council, and then through guidelines and policies that are developed by the body implementing it.
So I don't deny that one has to give thought to those issues, but as I understand it—and I speak to you, as a parliamentarian, perhaps of greater expertise in this—when I teach administrative law, I say “Here is what the statute says; there are many things that remain to be worked out through regulation and guideline, levels of specificity that are perhaps beyond the level of detail that parliamentarians want to deal with”. On the one hand I agree, you would want to address those. But I think that the statute itself probably is not the place where you need to do that. You would need to do that in regulation and then in guideline, and that's something that certainly the government of the day has some control over.
On the point of where you stop with all of this, I'm not sure I agree with you about the advantages of that kind of reach that you suggest. But if you think that's good, I would say that if you think that's where this leads—again, I'm not sure that would in fact be perfect—I would just say it's important not to let what you see as perfect be the enemy of the good. If this is good, the fact that there is something you think might be logically better or perfect is not a reason not to make a move on this.
Would it require further movement? No, of course not. You legislate as you see fit. You don't have to legislate any further than you do. You're never forced into legislating.
