As of March 28, 2022, code users can access the latest, updated editions of the National Model Codes, including the National Building Code of Canada 2020, the National Fire Code of Canada 2020, the National Plumbing Code of Canada 2020, and the National Energy Code of Canada for Buildings 2020. The Codes are developed by the Canadian Commission on Building and Fire Codes (CCBFC), and are published by the National Research Council of Canada (NRC).
The CCBFC has included nearly 400 updates in the latest editions of the National Model Codes. These replace the 2015 and 2017 editions of the codes.
Previous editions of the codes also remain available through these websites.
Provincial and territorial code regulations
Provincial and territorial governments have legislative authority over building design and construction within their jurisdictions, and adopt or adapt the National Model Codes into regulation in order for them to come into effect.
Provinces and territories were provided with advance copies of the latest code changes in December 2021, so that they could prepare regulations based on the updates.
Current provincial and territorial building, fire, plumbing and energy regulations will remain in effect until these latest editions of the National Model Codes are adopted, with or without modifications, by the provincial or territorial authority having jurisdiction.
