What Building Officials need to know about Tarion

By law, all new homes in Ontario built by a licenced vendor or builder comes with a statutory warranty under the Ontario New Home Warranties Plan Act (ONHWPA).

This statutory warranty protection follows the home and is valid for seven years from the original date of possession, regardless of who owns the home. 

Tarion ensures new home buyers receive the statutory warranty coverage they are entitled to under the Act.   

Every day, Tarion helps to build confidence in Ontario’s new home building industry by backstopping the new home warranty protection provided to homeowners. This section contains resources that may be helpful to you, your building department, and your local association.

If you have questions about Tarion, the warranty program or would like us to speak to your building department or local chapter, please contact us at stakeholderrelations@tarion.com.
