Changes to the Building Code Act

Relevant amendments to the Building Code Act are available here for reference after they are sent out through CodeNews.

June 8, 2023

Legislative changes were made to the Building Code Act as part of the Helping Homebuyers, Protecting Tenants Act, 2023. The changes provide additional options for the ministry to enforce the Act and the Building Code in the areas in which Ontario has jurisdiction (that is, areas without municipal incorporation).

July 21, 2020

Legislative changes were made to the Building Code Act as part of the COVID-19 Economic Recovery Act, 2020. The changes:

  • allow the Minister of Municipal Affairs and Housing to make most regulations under the Act, instead of the Lieutenant Governor in Council (Subsection 7(1), Subsections 34(0.1), (1), (1.1), (2), (2.1), (2.2) and (2.3))
  • clarify the importance of incorporating standards or codes, such as the National Construction Codes into Ontario’s Building Code (Subsection 34(1.1))
  • allow the minister to make regulations that require certain structural aspects of building construction be designed by professional engineers and architects to align with the National Construction Codes (Article 34(1.1)(2)).

These changes ensure Ontario can adopt the requirements of future editions of the National Construction Codes in a timely and efficient manner to help harmonize construction codes across Canada.

December 10, 2019

Bill 132, Better for People, Smarter for Business Act, 2019, received Royal Assent on December 10, 2019. It included the following Building Code amendments:

  • adding email as an additional way for building officials to serve notices and orders required under the Building Code Act and setting out when a notice or order served by email will be deemed to have been served (Subsection 27(1))
  • repealing mandatory reviews of energy and water conservation standards in the Building Code (Subsections 34(6) and 34(7))
  • dissolving the Building Code Conservation Advisory Council (Section 34.1)
