Event Information:
This presentation will provide a concise, high-level overview of the 2025 National Construction Codes, with a focus on the most significant technical changes introduced in the newly released 2025 National Building Code (NBC) and 2025 National Plumbing Code (NPC). The session is designed for professional engineers and EITs seeking an efficient briefing on what has changed and why it matters in practice.
The discussion will place these national updates in context by examining their relationship to the 2024 Ontario Building Code (OBC), including areas of alignment, divergence, and anticipated implications for engineering design, coordination, and regulatory review in Ontario. Particular attention will be given to changes that may affect structural, small buildings, fire safety, plumbing, and systems design, as well as provisions that signal broader shifts in regulatory direction.
The presentation will also highlight emerging themes reflected in the 2025 codes (such as resilience, climate considerations, modernization of technical requirements, and increased technical specificity), and how these themes may influence future Ontario code cycles and professional practice.
