Tarion Warranty Corporation

About Tarion

For the past 40 years, Tarion has been enhancing confidence in the new home buying experience. Tarion is a private, not-for-profit corporation that administers the Ontario New Home Warranties Plan Act, and backstops the warranty coverage. We set the standards for builder licensing and after sales service and step in when your builder cannot or will not fulfill their warranty obligations. Since 1976, Ontario’s new home warranty program has registered close to two million homes and paid out hundreds of millions of dollars in warranty claims. Our mandate is to serve the public interest, and is what guides us every day.
