Thank you for the question.
I cannot comment, of course, about the past estimates, but the current situation is the following.
The scope of the project could have been different and the process on which we have embarked is to find a private partner consortium to better define what the scope will be and to, of course, in that process identify and refine what the budget will be. It's difficult today to have precise numbers, or it would probably be imprudent to throw numbers out, because the scope is not defined. The corridor is, but the scope is not defined. The technology is not well defined yet.
I think we absolutely need the support of the expertise in the private corporations to support us. The process in which we are, the procurement process, is to select that partner and work in codevelopment to provide Canadians with the best economical and operational solutions in a few years to come.
