We obviously have a good sense of how many customers each of our members has, and we can create a cumulative list from that. There are entities in Canada using natural gas that are not our members. Obviously, we don't have a sense of how much is being used there; we would look to others to find that information.
Where are we going to find it? There isn't a single point for it. In each province it might be collected by a different body in a different way. We can give you a rough, general sense, but we can't be particularly precise. I think we should be able to be more precise than we are.
I can tell you that there are roughly seven million customers for natural gas, and as I noted, it represents a customer base of about 20 million Canadians, because each customer has a meter and we know how many meters our members have.
