That comes down to the governance of major procurement projects.
Public Services and Procurement Canada is in charge of those major projects. Unfortunately, my office didn't examine that. It's possible that my fellow officer of Parliament, the Auditor General, has already looked into that, so she may have some insight into better governance mechanisms for major procurement projects.
It's clear from the cost estimates I've provided to parliamentarians since becoming the Parliamentary Budget Officer that the mechanisms are in need of improvement.
