I believe the outstanding question was on the regulatory side.
South of 60, the Major Projects Management Office has timeframes within which it works. Once a proponent brings in a project description, and it's fully acceptable and departments have acknowledged they have to make a regulatory decision, the process will take two years. The Canadian Environmental Assessment Act was just amended, and for comprehensive studies, they have reduced that timeline even further, I believe, to one year. So there are fairly stringent timelines. That being said, the clock can stop if proponents don't provide the necessary information as they go through the process.
As to your other question about the different decision-making and who makes the decision on what type of environmental assessment there will be, that is based on the legislation. There is a law list that decides which projects has a comprehensive study versus a screening level study, and then the Minister of the Environment undertakes whether there will be a review panel or not, based on public interest and the environmental impacts.
