The short answer is that I don't know the extent to which governance has contributed to this; however, choosing a ship that has not yet been built anywhere increases the risk. That's probably one important aspect. Choosing a design on paper as opposed to choosing another type of ship that had already been built and for which costs to a certain extent were known would probably have reduced the risks somewhat, but not entirely. It all depends on the specifications that the Royal Canadian Navy has and the tailoring of that other ship that would have been made.
With respect to governance, that will be a very good question for specialists in that area to look at, notably the Auditor General. Like you, I'm concerned about the cost increase of this type of procurement, because we're talking dozens of billions of dollars in increase when it comes to cost, and there doesn't seem to be a clear rationale, at least not one that's obvious to me when it comes to explaining these cost increases.
