I will tell you that what we're hearing from the expert officials—we have some here with us today, but there are many others—is that, yes, it's hard to predict the exact amount of funding needed to move what are often very complex procurement processes forward.
They're doing what they can at the front end. Additional needs often crop up that were not noted at the outset. We know that once the work begins, equipment that's been produced at one point for other countries may not quite meet Canada's needs. Canada is a huge country with a geography and surface area that may differ greatly from what's found elsewhere on the planet.
So it does happen regularly, but thankfully not always, that the initial estimates differ from what's needed in the end due to the Canadian context, which is a little more complex than what we sometimes see in other countries.
