At least eight incidents of balcony glass panels falling from the D’Or Condos in Vaughan, Ontario, have raised concerns about the safety of the building’s glass guardrail systems.
Since the complex opened in 2023, residents have reported multiple cases of glass panels falling onto the street below. The City of Vaughan launched an investigation in June 2025, issuing an unsafe building order and requiring engineering assessments and testing.
The investigation concluded in January 2026, when a professional engineer certified that the balcony guardrail system met or exceeded Ontario Building Code requirements. The city subsequently lifted the order. However, residents report that further incidents have occurred since then.
The cause of the failures remains undetermined. Developer Fernbrook Homes says investigations involved engineers, testing agencies and the railing contractor. However, the broken panels were reportedly removed before they could be examined, preventing investigators from identifying the failure mechanism. 
The developer has also requested maintenance records from the condominium corporation and property management company.
The incidents raise questions about the long-term safety, maintenance and performance of glass balcony guardrail systems.
