Canada follows a unique building code system where the National Research Council (NRC) develops model codes, but provinces and territories adopt and modify these codes independently. This creates a complex landscape for metal building construction across the country. This guide helps architects, contractors, and building owners navigate the different provincial requirements and understand code evolution from 2015 to 2024.
How Canadian Building Codes Work
- National Model Codes: Developed by NRC (National Research Council of Canada).
- Provincial Adoption: Each province adopts and may modify national codes.
- Local Amendments: Municipalities can add additional requirements.
- Federal Buildings: Use National Building Code directly.
