National Model Construction Codes

Canada's National Model Construction Codes and Guides 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). The NRC Canadian Codes Centre plays a vital role in this process by providing technical, research and administrative support to the CCBFC and its related committees.

These Codes are adopted, with or without modifications, and enforced by most provinces and territories. Standards development organizations publish other Canadian construction codes and standards.

Individuals from all segments of the Canadian construction community have the opportunity to contribute to development of the Codes, either directly, through committee membership, or indirectly, by submitting or commenting on proposed changes.

The National Model Construction Codes can be purchased through NRC's Virtual Store (print formats, downloadable PDFs and online subscriptions). For more information about the online subscription service, see the NRC CODES-GUIDES Online Library.

Code development

Canada's approach to developing the National Model Construction Codes is evolving to better respond to innovation and globalization.

Four of the Codes are now in an objective-based format: the National Building Code of Canada (NBC) 2010, National Fire Code of Canada (NFC) 2010, National Plumbing Code of Canada (2010) and National Energy Code of Canada for Buildings (NECB) 2011. A fifth code, the Model National Energy Code of Canada for Houses 1997 will no longer be published. Instead, provisions dealing with energy efficiency for housing have been incorporated into Part 9 of the 2010 NBC and were published as an interim change to that Code in December 2012. As for the National Farm Building Code of Canada 1995, the CCBFC has agreed to work on updating the requirements for large farm buildings with a view to their incorporation into the 2015 NBC and NFC.
