The Ministry of Municipal Housing and Affairs is currently in the process of developing a new channel for the submission of code change requests related to code provisions unique to the Ontario Building Code (i.e. Part 8 and Part 11). Due to the new harmonization commitments outlined in the signed Reconciliation Agreement, any code change request to a provision present in both the National and Ontario construction codes must be submitted through the National Code Development system. 

MMAH recommends submitting code change requests using an online link if the request is covered by both Codes. If submitting a code change request to a provision unique to Ontario’s Building Code, a form can be completed and sent to Codeinfo@ontario.ca with the Subject line: “2012  Building Code Change Request Form.”
