Canada’s Parliament Renovation: $5 Billion and Still Years From Completion

Canadians are facing a massive bill to restore and modernize the country’s historic Parliament buildings in Ottawa. The question is: how much will it cost, and how long will taxpayers have to wait?

The rehabilitation of Centre Block, home to the House of Commons and the Senate, is one of Canada’s largest and most complex heritage construction projects.

According to the federal government’s latest quarterly progress report, published September 29, 2026, the estimated cost of restoring Centre Block and building a new underground Parliament Welcome Centre remains between $4.5 billion and $5 billion, excluding taxes.

How much will it cost?

• Estimated total: $4.5 billion to $5 billion.
• Already spent: Approximately $1.94 billion as of September 15, 2026.
• Main construction completion: Targeted for 2030–2031.
• Expected reopening: Approximately one year after construction, potentially in 2031–2032.

These figures cover both the Centre Block rehabilitation and the new Parliament Welcome Centre, not simply repairs to the House of Commons chamber.

Why is the project taking so long?

The Centre Block requires far more than cosmetic repairs. The work includes strengthening the historic structure, replacing aging mechanical and electrical systems, installing modern technology, restoring heritage features and constructing additional underground space.

The Peace Tower’s foundation is also being strengthened. Historic masonry, stained glass, marble, woodwork and other architectural features must be preserved while the building is modernized.

The government describes this as the largest and most complex heritage rehabilitation project in Canadian history.

What does this mean for taxpayers?

The project is intended to preserve a national landmark for future generations while providing Parliament with modern facilities. However, a multibillion-dollar project extending over many years raises legitimate questions about cost control, scheduling and public accountability.

The federal government’s September 2026 report says the project remains within its approved cost and schedule parameters for the reporting period, although its schedule rating indicates challenges that could affect delivery.

Canadians should continue to receive clear updates on spending, construction milestones and any changes to the expected completion date.

The bottom line

Canada’s Parliament renovation is currently budgeted at up to $5 billion, with main construction expected to finish in 2030 or 2031. The Centre Block is expected to reopen about a year later.

The key question for taxpayers is whether the government can complete this enormous heritage project within its stated budget and timeline.
