This difference would be due, first of all, to the fact that we went from one to two ships, which obviously has an impact on the cost. However, we don't know how the government arrived at the $1.3‑billion estimate.
So it is difficult for me to explain the difference between our cost estimate and the government's. The Minister of Fisheries and Oceans may be tabling a new updated cost estimate soon, which may shed some light on this.
Based on the estimates and data we have been able to use, we are fully confident in our cost estimate. However, unfortunately I cannot comment on the appropriateness of the 2013 government estimate, because I do not know how the government arrived at that figure.
