Yes, Mr. Chair, thank you for the question.
This is a project that we're very proud of. It's the largest, most complex heritage project ever undertaken in Canada. It's not only restoration, but it's bringing the building up to modern standards—the building systems, the seismic standards, the security posture of the building, making it green and accessible. These are very high standards relative to the nature of the building when it was constructed.
We're very pleased with the progress, the planning around it. As members know, there's a whole domino effect on the planning, of identifying swing space, moving, and then moving facilities back in. That's been a big part of it.
There's been $4.2 billion in work provided to date as part of this project. Right now on the Centre Block, I believe there are 400 workers in place. As the long-term plans unfold, we would see, I believe, a peak of 1,500 workers as part of that project, so it's a source of employment for some high-skilled trades and other workers as part of the rehabilitation.
