What Tarion Warranty Doesn't Cover in Ontario: Common Exclusions

New home buyers often treat Tarion's statutory warranty as an all-purpose safety net — if something goes wrong with the house, Tarion will fix it. That's not quite accurate, and the gap between what people expect and what's actually covered is where a lot of frustration comes from.

Tarion's warranty, administered under the Ontario New Home Warranties Plan Act, covers defects in work and materials within defined periods and categories. It was never designed to cover everything that can happen to a house over time. Knowing the general shape of what falls outside coverage helps you set realistic expectations — and figure out where a different remedy (a manufacturer's warranty, your own insurance, or ordinary maintenance) is the right path instead.

Tarion Covers Defects — Not Everything That Goes Wrong

The core distinction to hold onto: Tarion covers construction and material defects that fall within its published standards and your applicable warranty period (commonly described as Year 1, Year 2, and Year 7, with Year 7 addressing major structural defects specifically). It does not cover every problem a homeowner might encounter, even in a relatively new home.

Normal Wear, Maintenance, and Homeowner-Caused Issues

Some of the most common claim denials fall into this category:

• Ordinary wear and tear that comes with normal use over time
• Damage caused by a homeowner's failure to perform routine maintenance
• Damage resulting from alterations, renovations, or work the homeowner had done after taking possession
• Damage caused by misuse, neglect, or accidents unrelated to construction quality

Tarion's warranty is about defects that originate with construction — not the ordinary aging of a home or damage introduced after the fact.

Items Typically Covered by a Different Warranty

Not everything in your new home falls under Tarion at all:

• Appliances (fridge, stove, dishwasher, and similar) are generally covered by the manufacturer's own warranty, not Tarion's new home warranty
• Items supplied and installed by parties outside the standard construction scope may carry their own separate warranty terms

If an appliance stops working, your first call is usually the manufacturer, not Tarion.

Cosmetic and Pre-Existing Items Noted at Possession

Deficiencies that are cosmetic in nature, or that were identified (and often acknowledged) at your pre-delivery inspection, are generally expected to be tracked and addressed through the standard claims process for the applicable warranty period — but purely cosmetic issues discovered well after possession, without documentation, can be harder to establish. This is part of why documenting everything carefully at your PDI matters.

Secondary Damage and Consequential Losses

Tarion's warranty is generally structured around repairing the defect itself, not necessarily every downstream consequence of it. Losses like temporary accommodation costs, lost time, or other indirect impacts of a defect are treated differently than the direct repair itself, and coverage for these can be limited or excluded depending on the circumstances.

What's Simply Uncertain — Get It Confirmed

Some categories genuinely depend on the specific facts of your situation and aren't safe to generalize about, including:

• Landscaping, grading, and seasonal exterior items in certain circumstances
• Issues tied to municipal services or utilities outside the builder's control
• Reduced protection scenarios for purchasers who register or move in later than typical

Rather than assuming an item is or isn't covered, the reliable path is to check Tarion's current published construction performance guidelines or ask a lawyer familiar with new home warranty claims.
