Thank you for the question.
As I said earlier, the first project was established or looked at in 1997.
Since then, the scope of the projects changed following amendments and requirements from parliamentarians and senators. We have also had to deal with a lot of changes in code and in an increased deterioration of West Block, especially the interior.
In 2007, we established the new baseline for the next five years. We are completely up to date in that respect. As you can see, in 2007, we had said that we would start work on West Block, the Sir John A. Macdonald Building and the Wellington Building. That's what we are currently doing. We awarded the contracts and started carrying out these projects.
There is currently an acceleration of the different projects under way, and we intend to continue at that pace. That's why we have five-year plans. We can better control costs and better report to the government on what we did over those five years. It enables us to submit a request for another five-year period. It allows us and the government to exercise control that ensures we have a more realistic vision of things. A 25-year plan is more difficult to carry out, whereas a five-year plan is clear.
