We continue to monitor the building on an ongoing basis. Health and safety is the number one priority, and it is the real reason we've been collectively putting all this effort into making sure that the building is emptied prior to 2019, when we have that assessment that there really is an elevated risk that there could be a building system failure.
Again, all the buildings are different. In the Centre Block, the elevated risks are really around building systems—so mechanical systems or electrical systems—which, if there were a failure, would impact the operations of Parliament. With regard to the West Block, structural stability was the prime, critical factor facing that building.
