July 1 to September 30, 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 (PWC). 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.

Status: On track
Basement excavation: Approximately 5,300 truckloads
Centre Block: Exterior
Masonry wall dismantling in the courtyards and copper roof removals continue in preparation for rebuild. Installation of the Trompe L’oeil (decorative tarp) on the south façade is underway and is expecting to be complete before winter.

Project spotlight
Each quarter, we highlight an element of work being done on the Centre Block project.
A new foundation for a historic landmark
The Peace Tower's foundation was strengthened and made more stable while protecting the historic structure above. Workers carefully excavated beneath the tower and poured a thick concrete foundation around its 4 main piers. This new foundation was then connected to the building’s new level 1 floor to help strengthen the structure.
Efforts are focused on the rehabilitation of the tower itself now that the base is reinforced. Once completed, the Peace Tower will look much like it did before, while benefiting from upgrades that will help preserve it for future generations. Standing tall over Parliament Hill, it will continue to symbolize Canada’s enduring values of peace, democracy, and unity, inspiring Canadians for another hundred years and beyond.
