Revocation of Registration

PLEASE NOTE: If designated, on February 1, 2021 the Home Construction Regulatory Authority (HCRA) will assume responsibility for builder and vendor licensing in the province of Ontario. At that time, some of the functions addressed on this page will no longer be handled by Tarion. You can find out more here


Under the Ontario New Home Warranties Plan Act, Tarion has the power to refuse an application for registration or renewal, and to suspend or revoke a builder or vendor's registration. Tarion may choose to take such action for a number of reasons, including situations where a builder or vendor fails to provide Tarion with financial information or required security.

Notice of Proposal

In order to do so, Tarion must first issue a Notice of Proposal (NOP) to the builder setting out Tarion's reasons for the proposed refusal, suspension, or revocation.

If the builder disputes the reasons, the builder may appeal the NOP to the Licence Appeal Tribunal (LAT), which is an independent adjudicative government agency.  If the appeal is not resolved between Tarion and the builder, LAT will hold a hearing and, based on evidence provided by Tarion and the builder and applicable law, will determine whether the builder's registration should be refused, suspended, or revoked. 

For more information about LAT or the NOP process, please visit LAT's website.

Ontario Builder Directory

Tarion's Ontario Builder Directory indicates whether a builder's registration has been revoked, refused or suspended.  It also lets you know when a registered builder is appealing a Notice of Proposal at the Licence Appeal Tribunal. ​​
