May is Building Safety Month

2025 marks the 50th Anniversary of the Ontario Building Code (OBC). This year, we recognize 50 years of the OBC and how it has shaped public safety during Building Safety Month.   

​

The Government of Ontario introduced the first Ontario Building Code in 1975 to promote public safety through the application of uniform building standards. The OBC established technical requirements for all building construction and demolition in the province.   The Ontario Building Code has evolved significantly since its introduction in 1975, with major updates incorporating new technologies and safety standards.  Key changes to the Building Code over the last 50 years include: Barrier-free accessibility requirements, Enhanced fire safety measures, Energy efficiency standards, Climate resilience measures & more.

​

Building Officials in Ontario have the important job of enforcing the building code and ensuring that construction and renovations meet safety and quality standards.  Over the last 50 years, the role of a building official has become much more complex.   In the early days, building enforcement was informal, handled by local by-law officers with little training. Without standardized codes, inspections were conducted based on basic safety concerns. With the introduction of the building code, professional building inspectors became necessary. The role grew beyond inspections to include plan reviews, zoning compliance, and fire & safety enforcement and more!

 As we observe Building Safety Month this May, we acknowledge the evolution of the Ontario Building Code over the last 50 years and its role in keeping Ontario safe.
