The Canadian Commission on Building and Fire Codes is responsible for the development of the National Model Construction Codes. NRC publishes the Codes and, through the Canadian Codes Centre, ensures that the best available knowledge from across Canada and around the world is brought to bear on their development. NRC also publishes several User's Guides for the Codes as well as some provincial codes.

To order the National Model Construction Codes, visit the NRC virtual store. Most are available through online subscriptions. Printing is disabled for the electronic Codes and Guides.
