Essentially what it does is force the companies to constantly, from day to day, look at their safety issues to ensure that they're meeting the regulatory requirements or, indeed, exceeding the regulatory requirements. What we do is go in and verify that they have the systems in place to show us that they're doing that.
As Mr. Eley pointed out, it's a much more proactive system. Instead of waiting for Transport Canada to find some flaw in their system, the safety management system actually forces them to go out and look for the flaws, to look for the deficiencies in their system, and also to develop plans to rectify those flaws.
