Codes Canada publications improve with each edition thanks to the contributions of inspectors, designers, suppliers, contractors, researchers, instructors, and others. Every change request is reviewed by a Canadian Commission on Building and Fire Codes (CCBFC) standing committee.

Typical changes:

  • Accommodate new construction techniques and systems
  • Clarify requirements
  • Update references to standards
  • Propose expansion of scope or objective.

Do you have a suggestion to improve one of the codes? If so, please read the detailed guidelines and, for each change request, submit a separate code change request using the online form provided.

Your change request will be considered for the 2020 editions of Codes Canada publications and should include:

  • The existing code requirement, if applicable
  • The reasons for the change or addition
  • Your proposed revision or new requirement
  • Supporting documentation, including cost/benefit data
  • The enforcement implications
  • The related code objectives
