It all depends on the nature of the activity. I'm not sure that the same conditions apply to oil and gas development and to shipping. A system is already in place to govern the exploration operations of oil companies, for instance. This system, which is based on other laws, is rather air-tight. Should there be any danger of a spill, for instance, the National Energy Board takes the matter in hand and ensures that steps are taken to correct the problem immediately or to intervene.
