Question 1:

What are Codes Canada publications?

Answer to question 1:

Codes Canada publishes five national model codes, in English and in French: the National Building Code of Canada (NBC), National Fire Code of Canada (NFC), National Plumbing Code of Canada (NPC) and National Energy Code of Canada for Buildings (NECB). They also include the National Farm Building Code (last published in 1995).

The Codes are developed and maintained by the Canadian Commission on Building and Fire Codes (CCBFC), an independent committee of volunteers established by the National Research Council of Canada (NRC). They are published by NRC as models for provincial and territorial building and fire regulations and must be adopted by an authority having jurisdiction to come into effect. In some cases, they are amended and/or supplemented to suit regional needs, and then published as provincial Codes.

Question 2:

How are the Codes developed and updated?

Answer to question 2:

The Canadian Commission on Building and Fire Codes is responsible for developing and updating Codes Canada publications. It is assisted by nine standing committees and several task groups and working groups comprised of hundreds of volunteer members. The Codes are developed and updated using an extensive consensus-based process involving all sectors of the construction community and the public. This code development process benefits from the research, technical and administrative support of the NRC. Ongoing development and updating of Codes Canada publications is necessary so future editions can reflect improvements in technology, address emerging health and safety issues and generally continue to meet the evolving needs of the construction industry and Canadian society.

Question 3:

Have all the national model codes been updated?

Answer to question 3:

The NBC, NFC, NPC and NECB have been updated.

The Model National Energy Code for Houses, last published in 1997, will no longer be published separately. Its provisions dealing with energy efficiency for housing and small buildings have been incorporated into a new section of Part 9 of the NBC, Section 9.36.

With respect to the National Farm Building Code, last published in 1995, a Joint Task Group of the CCBFC and the Provincial/Territorial Policy Advisory Committee on Codes will examine farm building requirements this code cycle (2020). The fire and structural requirements in the National Farm Building Code are increasingly in conflict with the latest edition the National Building Code.

Question 4:

Have the intent statements been updated for the 2015 Codes?

Answer to question 4:

The intent statements pertaining to the 2015 Codes are available, free of charge on the Codes Canada website. The application statements for the 2010 Codes have not been updated as the CCBFC has discontinued their publication.

Question 5:

How different are the 2015 Codes from the 2010 editions?

Answer to question 5:

Since the 2010 editions of the NBC, NFC and NPC, nearly 600 technical changes have been incorporated in the 2015 editions to address technological advances, social policy and health and safety concerns. Examples of new areas can be found in the introduction of water use efficiency in the NPC and the expansion to six-story combustible construction in the NBC and NFC. A summary of the significant changes to these Codes is available on the Codes Canada website.

Question 6:

Will revisions to Codes Canada publications be published after they are released? If so how do I get the revisions?

Answer to question 6:

Revisions and errata approved by the CCBFC are published in mid-cycle, while emergency changes are released immediately. Revisions to Codes Canada publications are available on request. Please contact Publication Sales at for revisions and errata access.

Question 7:

If I find something wrong with the Codes that needs to be changed, who do I tell and what do I do? OR I would like to make a change to the Codes. How do I forward this change and who do I forward it to?

Answer to question 7:

Any code user can submit technical inquiries or request a change to the national code documents. Information on how to do this can be found on the Codes Canada website under Technical enquiries and Request a code change.
