2024 Ontario Building Code
Ontario has released a new Building Code to reduce regulatory burdens for the construction industry, increase the safety and quality of buildings, and make it easier to build housing.
The 2024 Building Code streamlines processes for the sector and increases harmonization with the National Construction Codes by eliminating at least 1,730 technical variations between the provincial and national requirements.
The 2024 Building Code comes into effect on January 1, 2025, with a three-month grace period until March 31, 2025 for certain designs that are already underway.
