Costs Skyrocket for Notre-Dame Basilica Renovation
Renovation costs for Montreal's iconic Notre-Dame Basilica have more than doubled, according to a report published on July 10, 2026. The budget for the restoration project has ballooned from an initial estimate of $50 million to over $100 million, leaving officials scrambling to secure additional funding.
Details of the Budget Overrun
The original renovation plan, approved in 2024, aimed to restore the basilica's deteriorating structure, including its famous stained-glass windows, intricate woodwork, and exterior stonework. However, unforeseen structural issues and rising material costs have driven the price tag up significantly. According to the report, the discovery of extensive water damage and weakened foundations added $30 million to the project. Additionally, the cost of specialized labor and imported materials surged due to inflation and supply chain disruptions.
Impact on the Project Timeline
The renovation, initially slated for completion in 2028, is now expected to be delayed by at least two years. The basilica remains open to visitors, but some sections are cordoned off for safety. “We are committed to preserving this historic landmark, but the financial challenges are immense,” said a spokesperson for the basilica. “We are exploring all options, including government grants and private donations, to cover the shortfall.”
Broader Implications for Heritage Sites
The cost overrun at Notre-Dame Basilica highlights a growing trend among heritage restoration projects in Canada. A 2025 study by the Canadian Heritage Foundation found that 60% of major restoration projects exceed their initial budgets by an average of 40%. Experts attribute this to aging infrastructure, stricter safety regulations, and volatile material costs. The basilica's situation may prompt a review of how heritage projects are funded and managed.
