In general, across our modes where safety management systems are applied, they are an additional set of distinct regulations that apply to the particular topic of how a company manages itself and requires certain provisions on how documents are kept and how training is done and a whole series of requirements that are very similar between the modes.
Those, as I said, are regulations. They're applied to that area, and we assess against those regulations in terms of compliance and their effectiveness.
In addition, we have a whole suite in all the modes of other regulations which have been there for some length of time and have been modified over time. They are directed at particular safety issues that have arisen through various factors in the past. Those regulations continue to be enforced, monitored and surveilled by Transport Canada.
There are multiple sets of regulations, but safety management systems are a different set of regulations and those regulations are applied in the same way as others.
Within the safety management system and the requirements that are regulated for a company, the company must put a plan together to carry out those regulatory requirements, and because they are how you do your business, how you document, flexibility is provided to the company in how they do that. That's where people sometimes have some confusion over whether this is self-regulation. The regulation is clearly laid out. They're required to follow the regulation, and how they do their operational plan or their management plan to carry out some of these things is left with some latitude. Inspectors look at that, and if there is a problem we have different ways to deal with that.
