Who we are

Tarion is a not-for-profit consumer protection organization established by the Ontario government  to administer the province’s new home warranty program. For over 40 years, Tarion has served new home buyers and new home owners by ensuring that one of their life’s biggest investments is protected.  

What we do

By law, all new homes built in Ontario are provided with a warranty by the builder. Tarion’s role is to ensure that buyers of newly built homes in Ontario receive the coverage they are entitled to under their builder’s warranty. Tarion’s responsibilities include:

  • Protecting consumers when builders fail to fulfill their warranty obligations;
  • Educating new home buyers and new home owners about their warranty rights and responsibilities;
  • Administering the MyHome online portal, which allows homeowners to manage their warranty and report defects to the builder and Tarion;
  • Facilitating the fair resolution of disputes between homeowners and builders over warranty coverage, repairs or customer service;
  • Assessing warranty claims to determine if they are valid either through an on-site inspection or alternative method of investigation;
  • In cases where a builder fails to address a valid warranty claim, resolving the claim directly with the homeowner either through compensation or repairs by a third party; and
  • Managing a guarantee fund to protect new home buyers, out of which compensation for warranty claims is paid.

Effective February 1, 2021, Tarion's previous licensing responsibilities have been transitioned to the Home Construction Regulatory Authority. The HCRA is now responsible for regulating new home builders and vendors in the province. To learn more about the HCRA, visit www.hcraontario.ca
