I think if you go back in the history, there were several attempted renovations of the Centre Block in the far past, but I wouldn't be able to go into the details of those. I think it is accurate that there were some planned restoration initiatives over a number of decades that didn't quite get to the point of realization.
One of the key elements is a kind of robust swing-space strategy. The West Block, the Government Conference Centre and the visitor welcome centre provided the ability to empty the building into facilities that would support the operations of Parliament.
