I'll start by saying that companies choose to voluntarily develop, implement, and maintain a safety management system because their customers demand it, quite frankly. It is a competitive advantage in our subsector of the industry. Market forces drive some of that, which is positive. It's good for the environment, it's good for shipping, and it's good for the customers and potentially the customers downstream.
Is Transport Canada auditing the voluntary SMS? I don't have an answer for you in term of frequency. I know that the dialogue has been there since Transport Canada was considering making it mandatory, so they're looking at models that already exist. But I don't have the exact number to give you, or the frequency of that auditing. That is something I'd have to follow up on for the committee.
