Proposed changes

From: National Research Council Canada

A Code Change Request (CCR) becomes a Proposed Change once it has been reviewed by a standing committee, under the supervision of the Canadian Commission on Building and Fire Codes, and work has been undertaken for development as either an approved task or a minor task. The outcome of the task work is a Proposed Change to the National Model Codes and follows the path outlined in the code development process.

This Proposed Change tracking database can be used by CCR proponents to follow the progress of proposed changes for a task linked to their CCR. Information in the database can be accessed using the filter option or toggle arrows to sort by:
