Consultation on New Agreements and Changes to Builder Bulletins

Thank you for sharing your invaluable feedback during the review of our Builder Bulletins and Vendor and Builder Agreements. Your input is crucial to guiding Tarion’s continued role in administering new home warranties and protections.

Tarion is in the process of analyzing and reviewing all feedback as part of our policy development. We will continue to keep homeowners, builders and industry informed of any changes to this initiative.


On February 1, 2021, the Home Construction Regulatory Authority (HCRA) will be designated as the new regulator of new home builders and vendors under the New Home Construction Licensing Act, 2017. At that time, Tarion will no longer be responsible for registering builders and vendors of new homes but will continue to administer warranties and protections under the Ontario New Home Warranties Plan Act.

Due to these changes, Tarion will need to adjust its operational policies.

Tarion is therefore consulting on proposed changes, including:

  • Eliminating certain Builder Bulletins and updating others to address changes to Tarion’s mandate following the launch of the HCRA;
  • Creating four new Registrar Bulletins; and 
  • Developing new standardized Vendor and Builder Agreements to align with the new home enrolment process.

Additionally, Tarion will be renaming existing and new bulletins as “Registrar Bulletins” and re-numbering them to provide a coherent and sequential framework. These changes will help ensure a smooth transition for the launch of the new regulatory authority. Your feedback will help to inform Tarion’s policy changes to support implementation of this key government initiative.
