Thank you.
Let's go back to the amendment you're proposing to the Canadian Environmental Protection Act. You say that an owner would have to prove that they took all appropriate measures to prevent, for example, a spill of substances or oil. However, how do we determine whether they actually took all necessary measures to prevent that? It's still rather vague. You might point to ignorance and the adage that “ignorance of the law is no excuse”, but how do we define that?
