One of the project's very clear mandates is affordability and transparency. I would say that from a governance perspective, on a scale of one to ten, Alto is probably at seventeen, because we have an independent board of directors; we have the Auditor General; we report to Transport Canada; we systematically publish every progress report, the quarterly reports. Everything is completely, completely public. That's really the foundation of the governance that's in place.
Second, not putting forward costs or promises too early is a good way to go. Today, we still have only a working hypothesis that the project could cost between $60 billion and $90 billion. Once I have done enough work, I'll be happy to come back and tell you what the budget is for the first segment, how we intend to stick to it and what the contingencies are. That will come a little later in the process.
