I would say there could be a provision in CEAA which basically states that where the Minister of the Environment determines that a project is of national significance, he or she may establish a panel review to review that project.
There are some similar sorts of provisions in CEAA right now. They're very complicated and they have not been used that much, but there is the option for individuals to petition the Minister of the Environment to establish a panel review, under several different sections.
This would be clear, and I think it would improve the overall operation of the act and ensure that the federal government is looking out for the environmental effects of projects that are really and truly national in scale.
