Key takeaways
  • The Tarion one-year warranty starts on the date of possession (occupancy date for a condominium), and the seven-year warranty runs to the seventh anniversary of possession.
  • Tarion claim forms have fixed windows, so the dates matter as much as the defect itself.
  • Delayed closing compensation is capped at $7,500 and is not payable for delays you agreed to in writing or that were unavoidable.

Buying a brand-new home or condo in Ontario is different from buying a resale. Instead of relying mainly on a home inspection, you also get a warranty backed by Tarion. It can cover problems that show up after you move in and some costs if closing is delayed.

The warranty only helps if you understand what it covers and when to file. This article walks through the three warranty periods, the claim form timeline, deposit protection and delay compensation, so you know what to track from the day you sign.

What the warranty covers

The Tarion warranty is layered. The one-year warranty starts on the date of possession, which for a condominium is the occupancy date. The two-year warranty covers items such as water penetration and heating and electrical systems. The seven-year warranty covers major structural defects and runs to the seventh anniversary of possession.

It helps to think of the layers as a timeline. The one-year warranty begins on possession, the two-year warranty covers items such as water penetration and heating and electrical systems, and the seven-year warranty covers major structural defects, so it runs for the longest period. The date that anchors the timeline is possession, or occupancy for a condominium, so record it carefully.

Which items fall into which layer, and what counts as a major structural defect, depends on the warranty rules and your specific home. Read the coverage details that come with your purchase and ask a lawyer if something is unclear.

Claim forms and deadlines

Claims are made on set forms, each with its own window, so put the dates in your calendar on possession day.

FormWhen it applies
Initial FormCan be started 1 day after possession and is automatically submitted on day 41
Year-End FormOpens on day 183 and is automatically submitted on day 365, with a 10-day grace period if you have written proof you reported the items to your builder
Second-Year FormCan be filed any time in year two
Major Structural Defect FormAfter year two but no later than seven years from possession

The written proof point is worth noting. Report problems to your builder in writing and keep copies, because that record is what the grace period depends on.

Because the Initial Form is automatically submitted on day 41, anything you want on it should be noted before then. The same applies to the Year-End Form, which is automatically submitted on day 365. Walking through your home early and again before those dates makes it easier to catch items in time.

Deposit protection before you move in

Tarion also protects deposits paid before closing. For freehold homes, the amount depends on when the agreement was signed. For agreements signed on or after January 1, 2018, protection is up to $60,000 for homes up to $600,000, and 10% of the price to a maximum of $100,000 above that. For agreements signed before 2018 the maximum is $40,000. For condominium units, deposit protection is up to $20,000.

Tarion has announced changes to how freehold deposit coverage works, including steps buyers may need to take shortly after signing. Confirm the current requirements for your agreement, and do it early.

Delayed closing and occupancy

New builds are often delayed. Tarion delay compensation is capped at $7,500 in total. It includes $150 per day for living expenses, with no receipts needed for those, plus receipted costs such as moving and storage. If the builder gives less than 10 days' notice of a delay, the buyer gets $1,500.

There is an important exception. Compensation is not payable when the delay comes from a mutual written agreement or an unavoidable delay, meaning extraordinary circumstances that are no fault of the builder or the purchaser. Builders often ask buyers to sign delay amendments, so read any such document carefully before you sign it.

What to do next

Frequently asked questions

When does the Tarion warranty start?

The one-year warranty starts on the date of possession, or the occupancy date for a condominium. The seven-year warranty runs to the seventh anniversary of possession.

When is the Tarion Year-End Form due?

The Year-End Form opens on day 183 and is automatically submitted on day 365. There is a 10-day grace period if you have written proof you reported the items to your builder. If you are close to or past those dates, how this applies depends on your situation, so it is worth confirming with a lawyer.

How much can I get if my closing is delayed?

Compensation is capped at $7,500 in total, including $150 per day for living expenses without receipts. It is not payable where the delay was agreed in writing or was unavoidable.

Does Tarion protect my deposit?

Yes, within limits. For condominium units, deposit protection is up to $20,000. Freehold limits depend on when you signed, so confirm the current rules for your agreement.
