Thank you very much for your question.
Mr. Chair, as I mentioned in my opening remarks, the West Block will be completed by 2017, in time for those celebrations. That includes the visitor welcome centre, which will be underground. The work on the East Block will not have started. There will be minimal visual work on the west pavilion of the Centre Block at that point. The work and the scaffolding around the East Block will be towards the east, and it will not be visible from the main grounds of Parliament Hill. This will be achieved without any significant acceleration, or any undue acceleration, of the work.
