January 1 to March 31 2026: Quarterly progress report update on the Centre Block project
We're restoring and modernizing the Centre Block. We're also designing and building the Parliament Welcome Centre. It's the largest and most complex heritage rehabilitation ever seen in Canada. We estimate the cost to be between $4.5 billion and $5 billion. We aim to complete main construction between 2030 and 2031. The Centre Block will reopen about 1 year later. This will allow Parliament to do testing and get the building ready for operations.

Project spotlight
Each quarter, we highlight an element of work being done on the Centre Block project.
Welcoming Canadian made
Restoring Centre Block, a symbol of Canada’s democracy, is a job that should be done by Canadians, for Canadians. From coast to coast to coast, we are encouraging Canadian companies to join us in restoring this iconic symbol of Canadian democracy.
With over 400 Canadian companies across eight provinces already contributing, there are still countless opportunities for Canadians to be part of this project.
