There has been some thought and some discussion on that. To my earlier point about communicating differently and being transparent, there's some overlap there.
I think it would be smart and wise to look at this with a different lens. An early assessment could be described exactly as such. It's an early estimate that is derived using parametric variables according to what we know at the time. For a 25-year procurement, things will change and we'll manage them accordingly.
Where I think real accountability and precision should start surfacing in a different language—that is, no longer as an estimate—is when we sign contracts. As we approach our time to sign contracts and bring submissions to Treasury Board, numbers are well derived and there's a lot of accuracy. We can then be held accountable to our contract and be asked to get the best contract possible instead of doing guesswork 10 years ahead of delivering something.
