Proposal summary

The Ministry of Municipal Affairs and Housing is entering its third and final phase of consultation on the next edition of Ontario’s Building Code. As part of this phase, changes to an energy efficiency requirement and sewage system provisions (Part 8 of the Building Code) are proposed.

Proposal details

Ontario’s Building Code is a regulation under the Building Code Act, 1992 which sets out minimum administrative and technical requirements for new construction, renovation, and change of use of buildings.

The Ministry of Municipal Affairs and Housing has been actively working on the development of the next edition of the Building Code since 2021. 

The third and final phase of consultation focuses mainly on remaining Ontario-specific proposals and issues identified through the first two phases of consultation. 

Due to their potential relevance to the environment, a proposal related to energy efficiency and proposed Part 8 changes on sewage systems are being posted separately from other Phase 3 proposals (see attached List of Proposed Changes to Sewage Systems and Energy Efficiency).  

The Phase 3 consultation consists of engagement and discussion in November/December 2022, and three simultaneous online postings. In addition to this current posting on proposed sewage system and energy efficiency changes, the other two postings are on the Regulatory Registry of Ontario on:

  1. General Proposed Changes for the Next Edition of Ontario’s Building Code
  2. Building Code Changes to Support More Homes Built Faster: Ontario’s Housing Supply Action Plan 2022-23

The ministry will continue to carefully review and analyze the feedback collected from all three phases of consultation. This information will inform the drafting of the next edition of Ontario’s Building Code.

Please submit comments on any of the proposed changes by: 

  1. using the link provided within the attached list of proposals, or
  2. submitting an email directly to buildingcode.consultation@ontario.ca with the Sentence(s) or Article number(s) as the subject line.

This posting is open for 45 days for feedback. A bulk comment form is also available and is attached below. 

Analysis of Regulatory Impact    

Costs: There are no new administrative costs anticipated for regulated entities.

Benefits: The proposed changes would update requirements and increase harmonization between Ontario’s Building Code and National Construction Codes.
