Mr. Chairman, I believe that all of this was sole-sourced. I might add that we contracted with Mr. Robertson as a follow-up to the work that he had done on the electrical generation study.
The information and the advice we needed was very technical. As Mr. Voytilla has pointed out, a lot of it -- in fact, most of it is not available in the Northwest Territories. We relied on Mr. Robertson's expertise to give us advice on where we could turn for the best advice. We were also committed to reviewing hydro potential at all of the aboriginal assemblies over the summer. We were working in a fairly tight time frame to get good advice before we went out and did presentations to aboriginal communities. Thank you.
