We're in consultations with our partners on this, to come to ground and get a better understanding of the timelines and what they will entail. We're not sure if we can close Centre Block down on a Friday and have West Block open on a Monday. There may be a transition period there. We're going to be looking to get some further information on that.
There's also the government conference centre, which is at the forefront of our attention. As we get closer to 2018, we'll have a better idea of what our personnel pressures will be. Will we have to maintain a fully operational Centre Block concurrently with a fully operational West Block and the government conference centre? Those are some of the unknowns we hope will become clear in the remainder of this calendar year.
