I'm no less surprised, Mr. Chair. We request an economic opinion from a research centre, from CERI, the Canadian Energy Research Institute, and from people working with the Government of Canada, and they give us a presentation that would not be accepted by a student with an MBA, a master's degree in business administration. In this kind of study, external factors also have to be considered. They are part of any economic assessment done today. Nowhere have external factors been calculated, such as the cost of water supply services, roads, health services, the cost to clean up land and air and so on. I'm very surprised.
Why don't you include the cost of external factors, which are calculated by all businesses operating in all fields, whether it be aluminum, Alcan, steel or others?
