Preparing for Change: Proposed 2024 Ontario Building Code Changes

The Ministry of Municipal Affairs and Housing is gearing up for significant changes to Part 3 of the Ontario Building Code (OBC) as part of the next edition of the Building Code Regulation, slated for release in early 2024. These changes are aimed at enhancing fire protection, occupant safety, and accessibility. 

Here's a glimpse into what the proposed changes entail:

Scope and Timeline: 

Anticipated to roll out in early 2024, it’s expected the new edition of the OBC will undergo a transitional period spanning 6-12 months. This adjustment period will allow stakeholders to adapt to the new requirements smoothly.

Basis for Change: 

With over 2,000 proposed changes, the next edition of the OBC will draw inspiration from various sources, including harmonization efforts with the National Building Code of Canada and recommendations from Ontario's Housing Supply Action Plan. Additionally, Ontario-specific modifications, influenced by Coroner's Inquest recommendations and stakeholder feedback, are in the pipeline.

New Occupancy Types: 

The proposed changes introduce new occupancy classifications, particularly within Group B and Group G occupancy categories. Notable additions include “home-type care” occupancies classified as Group B, Division 4, and various Divisions of agricultural occupancies under a new Group G category, such as "high-hazard” and "greenhouse” agricultural occupancies.

Farm Building Regulations: 

Proposed changes include a new Division B, Part 2, “Large Farm Buildings”, outlining technical specifications for large farm buildings concerning fire protection, structural loads, and HVAC systems as part of the effort to harmonize with the current National Building Code of Canada.. The proposed requirements within Part 2 will apply to specific types and sizes of agricultural major occupancy buildings, ensuring comprehensive safety measures across the board.

Building Fire and Life Safety Systems:

Harmonization with the National Building Code of Canada is proposed to have a significant impact on the requirements for buildings to be equipped with sprinkler and fire alarm systems, as well as impact the design of standpipe systems, mezzanines, and interconnected floor spaces within buildings. Understanding these changes will be instrumental to the smooth transition to a new OBC for projects throughout Ontario.

As we anticipate the official release of the 2024 Ontario Building Code Regulation, it's imperative for stakeholders to stay informed about these proposed changes. The Ministry's extensive public consultation process underscores the collaborative effort towards building a safer and more accessible built environment for all Ontarians.
