Thank you. It is a good question.
I would underline two key points. One is part of the long-term vision and plan. There is a need for additional committee rooms, so that's in the plan. These will be converted into permanent committee rooms on the Hill, where there is limited space. In that sense, it is a use of prime real estate.
The other issue is this we've studied several times whether the Centre Block could be done in two phases. The analysis back from experts each and every time has been to do it in one shot, as the deputy termed it earlier for the West Block. That is, to relocate both the House functions and the Senate functions out of the Centre Block at the same time so that we will have full access to the Centre Block to do the rehabilitation.
