I'll start with a bit of a generality and then drill down a little bit more in detail. Sylvain may have something to add to that as well.
The act applies to Canadian territorial waters and also out to 200 nautical miles. The act itself was developed in 1970. It was extremely robust. It was much ahead of its time and probably still may be, to a large degree, the most comprehensive and rigorous set of requirements in the world for the Arctic.
The associated regulations with that speak to areas such as the equipment required and the requirement for ships operating particularly in areas of pollution and other areas. It requires in the act zero discharge, for example. There are a number of areas along those lines. It's quite rigorous. It's applied by our inspectors in the north and we do make that fairly onerous within the normal level of inspection processes.
