Tarion Warranty Guide for Toronto Pre-Construction Condo Buyers
Every new home built in Ontario — including pre-construction condos in Toronto — is backed by a statutory warranty administered by Tarion Warranty Corporation, an organization established under the Ontario New Home Warranties Plan Act. Understanding what Tarion covers, for how long, and how to make a claim is an essential part of being a prepared pre-construction buyer. This guide walks through the full scope of Tarion protection, the Pre-Delivery Inspection process, and what to do if something goes wrong after you take possession.
What Is Tarion?
Tarion is the provincially mandated organization responsible for administering the statutory new home warranty in Ontario. All builders of new homes in the province — including condominium developers — must be registered with Tarion and must enroll each new unit they build in the warranty program before selling it. Tarion's role is to protect buyers when a builder fails to honour its warranty obligations, either by ensuring the builder fixes deficiencies or, in cases where the builder is unable or unwilling to do so, by compensating buyers directly.
Tarion also maintains a public registry of builder licences, including any conditions, suspensions, or outstanding claims — a useful research tool before committing to any pre-construction purchase.
Tarion Warranty Coverage: The Three Time Periods
Tarion warranty coverage is structured in three overlapping time windows, each covering a different category of defect. Coverage runs from the date you take possession (or, for condos, from the date of unit registration).
One-Year Warranty
Covers unauthorized substitutions (where the builder substitutes a different material or product than what was specified without your consent), violations of Ontario Building Code, and defects in work or materials. This is the broadest coverage window and the one most relevant for finish and workmanship issues you discover in your first year of ownership.
Two-Year Warranty
Covers defects in the building envelope (the exterior walls, windows, doors, and roof as a system), water penetration through the building envelope, defects in electrical, plumbing, and HVAC delivery systems that are part of the common elements or directly serving the unit, and violations of Ontario Building Code affecting those systems.
Seven-Year Warranty
Covers major structural defects — defined as defects in load-bearing elements of the building (foundation walls, columns, beams, floor and roof systems) that are so significant that the building is or may become unsafe, uninhabitable, or unfit for its intended use. This is the most serious coverage category and applies to the entire structure, not just individual units.
Condominium-Specific Warranty Coverage
For condo units, Tarion warranty applies at two levels: the individual unit (your specific suite) and the common elements (the shared building systems, lobby, amenities, garage, and exterior). Coverage for the common elements is held by the condominium corporation on behalf of all unit owners. It is important to understand that as an individual unit owner, you have warranty rights for your own suite, while the condo corporation is responsible for pursuing warranty claims on the common elements.
The Pre-Delivery Inspection (PDI)
Before you take possession of your new pre-construction condo, the builder will schedule a Pre-Delivery Inspection — a walkthrough of your unit where you and a builder representative document the condition of the suite before keys are handed over. The PDI is your opportunity to identify and formally note deficiencies: incomplete work, scratched surfaces, missing fixtures, or anything that doesn't match the specifications in your Agreement of Purchase and Sale.
Document everything in writing: the PDI Form becomes part of your warranty record. Any deficiency you note at the PDI should be repaired before or shortly after closing. Items not noted at the PDI are harder to claim later as a pre-existing issue.
Take photographs: supplement the written PDI form with dated photos of every deficiency you identify. This documentation supports any future warranty claim.
Bring a professional if possible: some buyers arrange for a home inspector or experienced friend to accompany them at the PDI. You are permitted to have a representative with you.
Don't rush: take the time you need. Builders may try to move PDIs along quickly — it is your right to be thorough.
How to Submit a Tarion Warranty Claim
If a builder fails to repair a warranty deficiency within the required timeframes, the process for escalating to Tarion follows a defined sequence. Tarion's online MyHome portal is the primary tool for submitting and tracking warranty claims. Key dates — the 30-day, Year 1, and Year 2 warranty submission windows — must be respected, as missing a submission deadline can affect your ability to claim for certain deficiencies.
Submit within the correct window: Tarion sets specific submission periods for each warranty year. Missing these windows can mean losing your right to claim for specific deficiencies, even if they're clearly covered.
Keep records: maintain a written log of all communications with the builder about deficiencies, including dates, responses, and outcomes. This record supports any escalation to Tarion.
Use MyHome: Tarion's online portal allows buyers to register their home, track their warranty timelines, and submit claims directly. Register as soon as you take possession.
What Tarion Does Not Cover
Tarion coverage has limits. It generally does not cover normal wear and tear, cosmetic damage caused by the owner, damage caused by improper maintenance, issues that are the owner's responsibility under the condo corporation's declaration, or deficiencies caused by third-party modifications to the unit. Understanding what is and is not covered helps you set realistic expectations and maintain your unit in a way that doesn't inadvertently void warranty coverage.
Frequently Asked Questions
Does Tarion coverage transfer if I sell my condo before the warranty expires?
Yes. Tarion warranty coverage transfers automatically to subsequent purchasers of the unit during the warranty period. If you sell your pre-construction unit on assignment or as a resale within the warranty period, the remaining warranty coverage passes to the new owner — a meaningful selling feature for recently completed buildings.
What happens if my builder goes out of business or refuses to honour warranty repairs?
This is precisely what Tarion's guarantee is designed for. If a registered builder is unable or unwilling to complete warranty repairs, Tarion can step in and either arrange for the repairs to be completed or compensate affected buyers within the program's statutory limits. This backstop protection is one of the key advantages of purchasing new construction in Ontario versus in jurisdictions without comparable warranty programs.
How long do I have to submit a warranty claim?
Tarion sets specific submission windows for each warranty year. It is important to submit claims within these defined periods — consult Tarion's official warranty submission calendar and the MyHome portal for your home's specific dates, as missing a window can affect coverage for items in that period.
Can I do a PDI on my own, or should I hire someone?
You can conduct the PDI yourself, and many buyers do. However, for buyers who are not familiar with construction standards or what to look for, having an experienced home inspector or a knowledgeable companion can make the process more thorough and catch deficiencies you might otherwise overlook. The cost of a PDI inspection is modest relative to the warranty value of catching and documenting issues before closing.
