Quick Answer Box:Tarion warranty is a mandatory protection for new homes in Ontario, covering defects, builder failures, and deposit loss for up to seven years. It gives buyers recourse if their builder cannot or will not address covered issues, safeguarding their investment and home.
What is Tarion Warranty?
A tarion warranty is a form of insurance and legal protection for new homebuyers in Ontario. The tarion warranty guarantees repairs and compensation for construction defects, deposit risks, and builder failures, all under the Ontario New Home Warranties Plan Act. Coverage lasts up to seven years and is administered by the Tarion Warranty Corporation, a non-profit regulator and insurer for newly built homes. This mandatory new house warranty is a crucial safeguard when building a house in Ontario Canada, offering peace of mind to buyers and ensuring home protection from the start of construction through to years after occupancy.
The Role of Tarion Warranty Corporation
The Tarion Warranty Corporation is the non-profit administrator of the Ontario New Home Warranties Plan Act. Since 1976, it has ensured all newly built homes in Ontario are covered by required warranties. Tarion oversees builder compliance, mediates disputes, and steps in if a builder fails to fulfill obligations or leaves a project unfinished.
Tarion also educates homebuyers and homeowners about their rights, the warranty claim process, and timeframes for filing complaints. While the warranty is technically provided by the builder, Tarion enforces regulations and adjudicates disagreements to protect consumers. For individuals building a house in Ontario Canada, selecting a Tarion-registered builder is critical for home protection and consumer security. Obtaining your tarion warranty from a reputable Tarion-registered builder can make all the difference in securing your investment and avoiding future disputes.
HCRA Meaning and Its Context
The HCRA meaning refers to the Home Construction Regulatory Authority, which licenses builders and vendors in Ontario. The HCRA’s main job is to ensure only reputable and qualified professionals build and sell new homes. While HCRA focuses on builder qualifications and ethics, the Tarion Warranty Corporation manages new house warranty coverage, including deposit protection and claims. Together, HCRA and Tarion work to provide stringent standards and effective homebuyer recourse.
Tarion Warranty Coverage
Tarion warranty coverage is structured across three main timeframes: one, two, and seven years. Each period addresses specific types of defects and construction failures, giving homeowners staged protection as their home settles and ages. A tarion warranty delivers robust coverage for homebuyers, shielding against a range of risks that may not be immediately apparent during initial occupancy.
1-Year Warranty
- Defects in work and materials throughout the home.
- Ontario Building Code violations present at possession.
- Unauthorized substitutions and assurance the home is fit for habitation.
2-Year Warranty
- Water penetration through basement walls, foundations, or building envelopes.
- Defects in electrical, plumbing, mechanical, and HVAC systems.
- Defective exterior cladding and windows.
- Major Building Code health and safety violations.
7-Year Warranty
- Structural failure or collapse involving load-bearing elements (walls, beams, foundation).
- Environmentally hazardous substances (covered up to $50,000).
- Septic system failures (covered up to $25,000)
Condominium Units
Condo units carry the same 1/2/7 year structure as freehold homes. However, common elements—such as lobbies, shared roofs, parking garages—are covered under a separate warranty, with an aggregate limit of up to $3,500,000 per project.
The tarion warranty is always attached to the home, not the homeowner. If you sell your home within the seven-year period, any remaining warranty automatically transfers to the new owner, protecting both buyers and sellers.
Tarion Insurance and Extended Coverage
Tarion insurance provides essential coverage for new home buyers, supplementing what builders offer directly. If your builder’s insurance fails or does not cover a certain loss, tarion warranty steps in as an additional safety net. This is vital in cases of builder insolvency or unaddressed defects.

What is Not Covered by Tarion Warranty?
Certain exclusions apply to every new house warranty. Tarion warranty does not provide coverage for:
- Everyday wear and tear from normal use.
- Damage caused by lack of homeowner maintenance, improper repairs, or unauthorized alterations.
- Minor cosmetic cracks and blemishes within accepted tolerance limits.
- Landscaping elements (lawns, shrubs, and trees) unless included in a major grading issue.
- Issues from non-residential uses, such as home-based businesses causing damage.
- Materials, finishes, or items supplied by the homeowner after closing.
- Environmental hazards not outlined explicitly (e.g., radon unless proven part of a major defect).
- Acts of vandalism, theft, or natural disasters.
- Appliances and finishes separately covered by the manufacturer.
Understanding these limitations helps Ontario homeowners avoid common misconceptions during the claims process. For full details, always consult the official Construction Performance Guidelines and review your warranty certificate.
Home Protection Beyond Tarion
Home protection under Tarion complements other safeguards like home insurance policies and manufacturer warranties. While Tarion focuses on construction and builder-related failures, it is prudent to secure additional policies—especially as your home ages beyond the seven-year mark.
Tarion Deposit Protection Explained
For many buyers, the deposit is one of the largest up-front risks. Tarion deposit protection exists to return your deposit if your builder cancels the transaction, becomes insolvent, or cannot deliver the home.
Coverage Details:
- Freehold Homes: Deposits are protected up to $100,000.
- Condominiums: Deposit protection is mandated by different rules, but Tarion also provides delayed occupancy and cancellation coverage.
- Maximum Coverage: For homes purchased after February 1, 2021, deposit protection has increased to $400,000 in certain scenarios of builder default.
Buyers purchasing after January 1, 2026, must notify Tarion within 45 days of the transaction for maximum coverage. Failure to complete timely Tarion registration can mean reduced compensation in cases of builder bankruptcy or cancellation.
Tip: Always insist on a written deposit receipt and retain all documents and correspondence. These records simplify any claim under the Tarion deposit protection program.
Tarion Registration for Deposit Coverage
Tarion registration is crucial for homebuyers. If you register your new home and deposit promptly after purchase, you’re eligible for full Tarion deposit protection. In addition, registration ensures a seamless claims process, as all documentation is linked in the Tarion My Home portal.
How to Make a Tarion Claim
Filing a claim under the Tarion warranty requires following clear procedures and observing claim periods.
Step-by-Step Tarion Warranty Claim Process
- Document the Problem: Photograph, record, and describe the defect in detail. Reference the Construction Performance Guidelines to confirm eligibility.
- Notify the Builder: Builders get the first chance to address the defect. Notify them in writing and document any communications.
- File With Tarion via MyHome: Log in using your Tarion login. In the MyHome portal, select and complete the relevant claim form:
- 30-Day Form*: Issues found within the first 30 days
- Year-End Form*: Issues left unresolved by the end of year one
- Second-Year Form*: Defects eligible under two-year coverage
- Major Structural Defect Form*: Claims up to year seven
- Allow Builder’s Repair Period: Builders typically have a 120-day window to assess and address defects. Track all communications in your MyHome portal.
- Request Tarion Conciliation: If your builder fails to resolve the issue, request a Tarion inspection and mediation. Tarion will review, inspect, and make a binding decision.
- Track and Follow Up: Monitor your claim’s status using MyHome. Always keep copies of receipts, reports, and all submitted documentation.
Tips for Avoiding Claim Denials
- Do not wait—report issues promptly to preserve your rights.
- Provide detailed descriptions and visual evidence.
- Complete every form correctly, and double-check required attachments.
- Never bypass builder notification before contacting Tarion.

Home Inspection, Tarion Pre-Delivery Inspection (PDI), and Their Importance
Home inspection and Tarion Pre-Delivery Inspection (PDI) are vital for homebuyers’ peace of mind, but they have distinct purposes and benefits.

Home Inspection
A home inspection, generally performed before closing on a resale or newly built home, is conducted by a licensed inspector. Inspectors check major systems, the building envelope, mechanicals, and structural integrity, highlighting issues outside the builder’s warranty scope. For a list of reputable home inspection services, see Ontario Association of Home Inspectors.
Tarion Pre-Delivery Inspection (PDI)
The PDI is a thorough walkthrough done before the possession of a new build. During your PDI, every concern or imperfection identified—however minor—is recorded on the official form. This record is essential for future warranty claims. The builder and buyer both sign the completed form, and it becomes a central piece of your warranty documentation.
How to Get the Most Out of Your PDI
- Bring tools: flashlight, camera, and notebook.
- Check all rooms, looking carefully at every wall, floor, and ceiling.
- Operate appliances, faucets, HVAC, and electronics.
- Record every visible issue, as unrecorded flaws may be hard to claim later.
- Insist on receiving a signed copy.
A comprehensive PDI means fewer disputes and faster repair of any deficiencies under Tarion warranty coverage.
Home Inspection vs. Pre-Delivery Inspection
While PDI is mandatory for Tarion warranty activation, a targeted home inspection is recommended for additional assurance, especially for buyers investing in custom homes or large-scale developments. Home inspection can help pinpoint potential issues not always visible at PDI, offering layered home protection.
Tarion Registration and Warranty Certificate Process
Step-by-Step Tarion Registration
- Collect Required Information: Gather your Home ID, builder or vendor name, property address, and deposit proof—details found in your purchase documents.
- Create a MyHome Account: Go to the Tarion MyHome portal and set up your account using your Tarion login.
- Enter Home Purchase Details: Upload necessary documents, register your new home, and submit deposit information.
- Receive Confirmation: Tarion acknowledges proper registration and secures your new house warranty.
Upcoming Changes in 2026
Effective January 1, 2026, new freehold homebuyers must complete Tarion registration within 45 days of purchase. This update ensures buyers are eligible for the most extensive deposit protection and comply fully with the Ontario New Home Warranties Plan Act.
Obtaining Your Home Warranty Certificate
Upon successful registration, Tarion will issue a home warranty certificate to the homeowner. This document serves as official proof of warranty coverage and is essential for claims. Retain this certificate along with your signed PDI and purchase agreement. If you decide to sell the property within the coverage period, the warranty certificate helps facilitate the transfer of the Tarion warranty and protects the next owner.
Builder Coverage vs. Tarion Warranty: What’s the Difference?
Understanding the distinction between builder coverage and Tarion warranty is key for protecting your investment. The builder is first responsible for rectifying deficiencies within their work. Tarion warranty coverage is activated if the builder fails to comply, goes out of business, or if disputes arise regarding the scope of defects.
- Builder: Must respond to homeowner complaints and make covered repairs directly. Responsible for general construction quality and warranty service.
- Tarion Warranty Corporation: Acts as regulator and insurer when the builder does not fulfill obligations, or if the builder is no longer able to do so.
- Homeowner: Should always notify and engage the builder first, then escalate through MyHome to Tarion if necessary.
Some protections, such as deposit reimbursement and major structural defect coverage, only come into play through Tarion if the original provider (the builder) cannot or will not act.
Comparison Table: Builder vs. Tarion Warranty Coverage
| Category | Builder Responsibility | Tarion Warranty Corporation Role | Homeowner Recourse |
|---|---|---|---|
| Construction Defects | Repair within specified timeframe | Acts if builder fails or refuses | Claim via MyHome or request conciliation |
| Deposit Protection | Hold deposit in trust | Refunds deposit if builder defaults | File claim with Tarion |
| Pre-delivery Inspection | Complete and document with buyer | Uses PDI form to verify claims | Reference PDI in claims |
| Major Structural Defects | Build to code, repair as needed | Backs up for bankruptcy/unaddressed issues | Submit “Major Defect” form |
| Registration Requirement | Assist buyer and provide info | Oversees compliance (especially after 2026) | Buyer must complete registration |
| Transfer of Warranty | N/A (warranty attaches to property) | Ensures coverage for subsequent owners | Remainder of coverage transfers |
To understand how this distinction matters for custom builds, see Custom Homes.
Tarion Warranty Fees and Costs
Tarion warranty fees are usually paid by the builder but are reflected in your home’s purchase price. Fee rates vary based on your home’s price bracket:
- For homes under $300,000, fees are lower than for higher-priced properties.
- For homes valued at $1,000,000 or more, fees are notably higher.
- The builder may list this cost in your agreement of purchase and sale for transparency.
While buyers don’t transmit payment directly to Tarion in most cases, it’s wise to check your contract to understand exactly what is included and what is billed as separate. Comprehensive service details can provide more insight into overall homebuilding costs.
Common Mistakes When Using Your Tarion Warranty
Mistakes with the Tarion warranty process can result in lost coverage or denied claims. Here are the leading pitfalls, with ways to avoid them:
- Missing the key registration deadlines, particularly after changes in 2026 make them more strict.
- Failing to use the correct form in the relevant time window, resulting in late or ineligible claims.
- Inadequate documentation, such as lacking dated photos, incomplete PDI forms, or missing receipts.
- Contacting Tarion before allowing your builder a fair opportunity to make repairs.
- Mistakenly assuming that resale homes lose Tarion protection—warranty coverage follows the home, not the owner.
- Neglecting to attend or fully participate in the PDI, leading to missed defect documentation.
- Overlooking the differences in warranty coverage between condominiums and freehold properties, especially regarding shared elements.
- Registering with Tarion My Home and following up only occasionally; active tracking of claim status is critical.
If you err in these steps, contact Tarion customer support as soon as possible. Some issues can be resolved if you act proactively, but deadlines are enforced rigorously.
Building a House in Ontario Canada: The Importance of Tarion Warranty
Building a house in Ontario Canada comes with many steps—from land acquisition to permits and finally construction. One important factor is ensuring your purchase is protected with a tarion warranty, which provides both peace of mind and legal recourse against builder failures. The tarion warranty gives buyers an assurance that their significant investment in a new home is well protected, fulfilling province-wide statutory requirements. Working with Tarion-registered builders also means you’re more likely to benefit from streamlined tarion registration and obtain your essential home warranty certificate efficiently.
Frequently Asked Questions
Is a Tarion warranty mandatory for all new homes in Ontario?
Yes, almost every new home or condominium built by a Tarion-registered builder must be covered by a Tarion warranty under the Ontario New Home Warranties Plan Act. Self-built homes and those not intended for sale may qualify for exemptions.
What happens if I miss the Tarion registration deadline?
Beginning January 1, 2026, missing the 45-day registration window for a new freehold home may reduce your deposit protection and limit your ability to claim if the builder defaults. Always register promptly through the Tarion MyHome portal.
Can I transfer the Tarion warranty if I sell my home?

What’s the difference between a home inspection and PDI?
A typical home inspection is a voluntary, independent evaluation, often performed for resale homes. The Tarion Pre-Delivery Inspection (PDI) is mandatory for all new home closings and is performed with your builder present to document and verify any deficiencies for Tarion claims.
How do I check my Tarion warranty coverage online?
Access the MyHome portal using your Tarion login to review your warranty details, submit warranty claims, obtain status updates, and download your official home warranty certificate. This online tool centralizes your Tarion coverage and makes claim tracking simple.
