The CBHCC encourages code users, interested organizations, and members of the public to get involved in the code development system. There are several ways to get involved:

Submit a code change request

Anyone can participate in the code development process by submitting a code change request to the Canadian Board for Harmonized Construction Codes.

Learn more about code change requests and submit a request here.

Volunteering on a code development committee

New members are recruited to serve on code development committees prior to each code cycle and on an as-needed basis throughout the code cycle.

Individuals interested in participating in national codes development work as a code development committee member are invited to submit their expression of interest at any time using the electronic form below.

Recruitment generally occurs prior to each code cycle in order to populate the committees, with members added as needed during the code cycle.

Please indicate which committee(s) you are interested in joining, include a summary of your relevant experience and send a separate email containing your résumé (required) and up to two recommendation/reference files (optional) to: CBHCC Committee Application.

Information on the 2030 code cycle committees will be posted when available.

Public reviews

The CBHCC regularly invites code users, the Codes community, and the public to participate in public reviews of proposed changes to the National Model Codes.

The purpose of public reviews is to:

  1. provide code users, the Codes community, and the public with a detailed look at proposed technical changes, and
  2. seek comment on each proposed technical change as to whether it should be approved, altered, or withdrawn.

Important

A public review is currently running until April 29, 2024 at 11:59 pm PDT, after which comments will no longer be accepted.

What happens after a public review?

The result of the public review process is a collection of comments on proposed code changes. The comments are sorted and analyzed by Codes Canada staff who are familiar with the development of the proposed changes, and propose a draft resolution to each comment.

The draft resolutions are validated by the responsible code development committees, which form the recommendations to the CBHCC. The recommendations to the CBHCC could be one of the following:

  • approve for publication,
  • revise for publication,
  • defer publication pending further development – subject to subsequent public review, or
  • withdraw proposed code change.

The CBHCC decides which changes will be published in the next edition of the National Model Codes based on the recommendations of the code development committees.
