Consultation on proposed Changes to Ontario’s Building Code

The Ministry of Municipal Affairs is seeking input from the public and industry stakeholders on changes for potential inclusion in the next edition of the Building Code.

The consultation, which will extend from July 14 to September 29, will include proposed requirements to support the implementation of the government’s Climate Change Action Plan (CCAP). To support CCAP, we are seeking input on proposed requirements that would reduce greenhouse gas (GHG) emissions in the building sector through changes to the Building Code.
