Winter 2020 National Code Consultation


The National Research Council of Canada (NRC) has launched a subsequent public consultation on proposed changes to the national construction codes, including the National Building Code of Canada, National Energy Code of Canada for Buildings and the National Plumbing Code of Canada that were not covered in the Fall 2019 consultation.

This public consultation will shape the content of the anticipated 2020 national codes and subsequently Ontario’s Building Code. Ontario code users are strongly encouraged to review and provide comments on the national proposals as they are expected to significantly influence the content of future editions to Ontario’s Building Code.  

As part of on-going efforts to transform the development of construction codes, provinces, territories and the federal government are committed to increasing the harmonization of the technical requirements across Canada. This will help streamline the national and provincial code development process, thereby reducing duplication and increasing efficiency.

The consultation runs from January 13, 2020 through March 13, 2020.  It can be accessed in the link below:


 The majority of the changes in NRC’s consultation are related to: 

  • Large Farm Buildings,
  • Accessibility,
  • Energy Efficiency,
  • Earthquake and Structural design,
  • Referenced document table,
  • Plumbing, and 
  • Others
