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. 

Registered builders who are appealing a NOP at LAT are indicated in the Ontario Builder Directory.

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