About the Centre Block project

The Centre Block is closed for renovations. This is the largest, most complex heritage rehabilitation project ever seen in Canada and is one of the largest in the world. Public Services and Procurement Canada (PSPC) will use innovative approaches and technologies throughout the project. When the Centre Block reopens, it will be ready to meet the needs of a 21st-century Parliament for years to come.

An essential investment for the future

PSPC is restoring and modernizing the Centre Block.

From the time the Centre Block opened in 1920, only minor repairs have been made to this iconic Canadian building. Short-term fixes were no longer a cost-effective option for preserving the building. It needed major repairs to bring it up to modern safety, environmental and accessibility standards and to make the building functional for parliamentarians. The Report of the Auditor General of Canada to the House of Commons. Chapter 3,: Rehabilitating the Parliament Buildings predicted the Centre Block would experience "total failure" sometime between 2019 and 2025.

The Centre Block had outdated systems and suffered from crumbling mortar, damaged sculptures and stained glass, as well as aging water pipes. Earthquake proofing and security are also issues that must be addressed, and the original electrical system cannot safely handle the multitude of modern technology required to support the operations of Parliament.
