I know those words are kind of scary, but they're really true. I can give you the example of what happened with the West Block. Two weeks after we vacated the West Block, there was a significant break of water pipes and there was significant flooding. That means that if the building had not been vacated for its rehabilitation, we would have had to shut down operations with no advance notice. That would have significantly hindered the operations of the government.
The way we can estimate or qualify the risk of failure of the building systems is by having regular building condition reports. We hire third parties to come and assess the state of our systems. I'm talking electrical, mechanical, water pipes, everything. That infrastructure for the Centre Block is indeed at critical risk of failure as of 2019, but right now, with the activity sequencing and with the progress of the work on time and on budget, it means that we should be able to vacate Centre Block and move everybody into the interim spaces on time before we get to that critical date.
