Quick Answer: Can a Builder Sue You for Not Closing?

Yes — and Ontario courts consistently rule in the builder's favour. If you fail to close on a pre-construction condo, the builder may keep your entire deposit and sue you for the difference between your purchase price and the price they ultimately resell the unit for, plus carrying costs, real estate commissions, and legal fees.

In Mattamy (Jock River) Ltd. v. Ishola (2024 ONSC 6231), the court ordered a defaulting buyer to pay $87,714 in damages on top of a forfeited $60,000 deposit — a total exposure of nearly $150,000.

However, buyers may have legal defences. If the builder failed to deliver required disclosure documents under the Condominium Act, 1998, violated Tarion addendum terms, or missed delayed-closing deadlines, a court may order the deposit returned and dismiss damage claims entirely, as occurred in DiCenzo (Linden Park) Holdings Inc. v. Sadeghyar (2026 ONSC 1566).

An appraisal shortfall alone — where your lender will not fund the full purchase price — is not a legal excuse to walk away. Ontario courts treat financing failure as the buyer's risk unless the Agreement of Purchase and Sale includes an express financing condition.

If you are facing a closing gap, consult a real estate litigation lawyer immediately — ideally 60 to 90 days before your closing date, while options like assignment, mutual release negotiation, or builder-breach defences are still available.

What Is Happening to Pre-Construction Condo Buyers in the GTA Right Now

This is one of the most financially stressful situations a homebuyer can face — and right now, thousands of buyers across the GTA are facing it at the same time.

Between 2021 and 2022, the Toronto condo market was moving fast and prices were at record highs. Many buyers signed Agreements of Purchase and Sale — the binding contracts committing them to purchase their units — at those peak prices. Those same condos are completing in 2026, and the market has shifted significantly. Urbanation reports approximately 22,000 GTA pre-construction condo units completing this year alone.

The problem is how mortgage financing works. Your lender funds the lower of the purchase price or the current appraised value of the unit. If your unit was contracted at $750,000 but the bank's appraiser now values it at $560,000, your lender may only advance $448,000 (assuming 80% of appraised value). The $190,000 gap is yours to cover in cash — and most buyers simply do not have it.

This situation is concentrated in areas like Vaughan, Markham, Scarborough, and North York, where pre-construction inventory was heaviest during the peak years. If you signed a pre-construction agreement during that period and your closing is approaching, you are far from alone — but you need to act quickly. Even common mistakes first-time homebuyers make, like assuming the purchase price would be fully funded, can have serious consequences at closing.

Pick Your Path: Which Situation Matches Yours?

Before reading further, identify which situation applies to you. Each path is different, and the options available to you depend entirely on timing.

Path A — Your closing is still 60 or more days away. You have the most options. This is the time to order an independent appraisal, audit your Agreement of Purchase and Sale for conditions, explore assignment, and consult a real estate lawyer who can assess your position before anything is off the table.

Path B — Your closing is within 30 days. Urgent action is needed. Assignment may still be possible but the window is narrow. A lawyer needs to review your Tarion addendum and disclosure documents immediately to identify any builder-breach defences.

Path C — You have already missed your closing date. You are in damage-control territory. The focus shifts to understanding your full liability and exploring whether a negotiated resolution with the builder is still possible before litigation is commenced.

Path D — You believe the builder may have breached the agreement first. This is the most important path to investigate. Read the Legal Defences section carefully — disclosure failures and Tarion addendum violations by the builder can fundamentally change your legal position.

What You Actually Owe When You Default: The Full Damages Formula

Failing to close on a pre-construction condo in Ontario exposes you to three distinct layers of financial liability. Your deposit is only the first layer — and it is the floor, not the ceiling, of your exposure.

Layer 1 — Deposit forfeiture. When you signed your Agreement of Purchase and Sale (APS), you paid deposits over time, typically totalling 15 to 20 percent of the purchase price. On a $700,000 condo, that is $105,000 to $140,000. Ontario courts have consistently held that the builder may retain the full deposit when the buyer fails to close, without needing to prove any actual loss beyond that amount.

Layer 2 — Resale shortfall damages. If the builder relists the unit and sells it for less than your contracted price, you may owe the difference. This is called loss of bargain. In Mattamy (Jock River) Ltd. v. Ishola (2024 ONSC 6231), the court found the builder resold during a market downturn at a lower price, and ordered the buyer to pay $87,714 in damages on top of the $60,000 forfeited deposit.

The builder does have a legal obligation to mitigate — meaning they must make reasonable efforts to resell the unit at fair market value rather than sit on it. In Mattamy v. Glover (2024 ONSC 4411), the court examined the builder's relisting strategy to confirm the mitigation duty was met. If a builder fails to mitigate, a court may reduce the damages owed.

Layer 3 — Ancillary costs. On top of the deposit and resale shortfall, Ontario courts regularly award the builder their additional costs: real estate commissions on the resale, legal fees for the action, and daily carrying costs — property taxes, utilities, insurance, and construction loan interest — for every day the unit sat vacant between your default and the resale.

Credit score impact. A court judgment against you remains on your credit bureau for six to seven years in Canada. This can affect your ability to secure a mortgage, a rental unit, or a business loan. A court judgment may also be enforced through wage garnishment in Ontario, giving the builder a direct claim against your employment income.

Deposit Forfeited vs. Full Lawsuit: Side-by-Side Comparison

Not every failed closing ends in a lawsuit. What happens to you depends primarily on what the builder gets when they resell your unit. Here is how the two main outcomes compare.

Scenario B is significantly more common in the 2026 GTA market because resale prices have declined across most pre-construction-heavy neighbourhoods. The Agreement of Purchase and Sale you signed gives the builder the right to pursue both remedies simultaneously.

Legal Defences That May Protect Ontario Buyers

Ontario buyers facing default are not always without legal options. Four defences may apply depending on how the builder and the APS were handled — and a lawyer can assess which, if any, applies to your situation.

Defence 1 — Builder disclosure failure. Under sections 73 and 74 of the Condominium Act, 1998, a builder must deliver a specific package of disclosure documents before a buyer is legally bound. If those documents were not properly delivered — or if the statutory cooling-off period of 10 days was never properly triggered — a buyer may retain the right to rescind the agreement and recover their deposit with interest. In DiCenzo (Linden Park) Holdings Inc. v. Sadeghyar (2026 ONSC 1566), the Ontario Superior Court found that the builder's failure to properly deliver the required Residential Condominium Buyer's Guide defeated the builder's claim to the deposit entirely. This defence turns on the specific documents delivered, the dates, and the method of delivery.

Defence 2 — Material change not properly disclosed. Under section 80 of the Condominium Act, 1998, if a builder makes a material change to the condominium — such as significant fee increases, changes to amenities, or alterations to the unit specifications — the buyer must receive a new 10-day rescission window. If that window was not provided, the buyer may have grounds to terminate and recover the deposit.

Defence 3 — Tarion addendum breach. Every new Ontario condominium purchase must include a Tarion Addendum (issued by Tarion Warranty Corporation, the body that administers new home warranties in Ontario). That addendum contains a Statement of Critical Dates governing when closing can occur and when delays must be formally communicated. If the builder missed its final closing deadline under the addendum without proper notice, the buyer may have a legal right to terminate and recover all deposits. This is worth examining carefully on any project that experienced significant delays.

Defence 4 — Relief from forfeiture. Under section 98 of the Courts of Justice Act (Ontario), a court may grant equitable relief from forfeiture where retaining the deposit would be unconscionable and the forfeited amount is grossly disproportionate to the builder's actual loss. This is a high bar. Courts have generally found that pre-construction deposits of 15 to 20 percent of the purchase price are reasonable pre-estimates of damages and do not attract relief. It may apply in narrower circumstances — for example, where the builder resells quickly at a profit and suffers no loss at all.

Financing conditions. If your APS contained an express financing condition that you did not waive, and you genuinely could not obtain financing, your inability to close may be legally excused. However, most pre-construction agreements do not include financing conditions, and buyers often waive them when present. Review the conditions and escape clauses in your APS carefully with a lawyer.

Step-by-Step: What to Do If You Cannot Close on Your Pre-Construction Condo

Step 1 — Order your own independent appraisal immediately.

Do not rely solely on your lender's appraisal. Commission an independent appraisal from a certified appraiser (AACI designation) to document the current market value in writing. This creates a formal record of the gap and may be useful in any subsequent negotiation or litigation.

Step 2 — Review your APS, Tarion addendum, and your home purchase closing checklist carefully.

Locate your closing obligations and the Statement of Critical Dates in your Tarion addendum. Check whether any financing condition was included in your APS and whether it was waived — and note every date the builder extended the closing deadline.

Step 3 — Check builder disclosure compliance.

Gather every document the builder sent you at signing and afterward. Confirm that the required disclosure package under the Condominium Act, 1998, ss. 73–74, was delivered within the required timeframe. Note the date of delivery and the method. If there is any ambiguity, flag it for your lawyer.

Step 4 — Explore assignment.

If your APS permits assignment — meaning the right to transfer your purchase contract to a new buyer before closing — this may be your cleanest exit. Assignment avoids default entirely. Not all APS agreements permit it, and those that do may require the builder's consent. Act quickly: the closer you are to closing, the harder it becomes to find an assignee.

Step 5 — Consider negotiating a mutual release.

Builders are not legally required to release you from your APS, but many will negotiate — particularly if the lawsuit would be costly, time-consuming, or reputationally difficult. A mutual release typically involves the buyer forfeiting part or all of their deposit in exchange for the builder waiving their right to sue for further damages. A lawyer can help you structure a demand and negotiate the terms.

Step 6 — Consult a real estate litigation lawyer at least 60 days before closing.

This is the step that changes the outcome. A lawyer can assess your defences, advise on assignment, approach the builder on a negotiated release, and, if necessary, represent you in litigation. Do not wait until closing day.

Common Mistakes Ontario Buyers Make When Facing an Appraisal Gap

Assuming the appraisal gap is the builder's problem. It is not. The Agreement of Purchase and Sale commits you to purchasing at the contracted price regardless of what your lender will advance. The financing risk is yours unless your APS expressly says otherwise.

Waiting until closing day to inform the builder. By the time closing day arrives, most of your options are gone. Assignment requires weeks. Mutual release negotiations require time. Disclosure-based defences need legal analysis. Contact a lawyer the moment you know there is a problem.

Assuming deposit forfeiture settles the matter. Many buyers believe that walking away simply means losing their deposit. It does not. If the builder resells your unit for less than your contracted price, they may still commence a lawsuit for the full shortfall — often months after you believed the matter was resolved.

Attempting to assign the contract without first checking the APS. Some pre-construction agreements prohibit assignment or require the builder's written consent. Assigning without that consent may itself constitute a breach of the APS and create additional liability.

Relying on a financing condition that was already waived. If you signed a waiver of your financing condition at any point during the purchase process, that protection is gone. Courts will not re-impose a condition that the buyer voluntarily surrendered.

Treating a mutual release as a foregone conclusion. Builders are not obligated to negotiate. In a market with many defaulting buyers, some builders are litigating aggressively to recover full losses and discourage others from walking away. An alternative dispute resolution approach can help, but it requires the builder's cooperation.

Failing to document the builder's own disclosure and delay history. Before defaulting, record every date the builder extended the closing, every document they delivered (and when), and every communication about the project timeline. This documentation may be essential if a disclosure-failure or Tarion-breach defence is later available to you.

Frequently Asked Questions: Pre-Construction Condo Appraisal Gap Ontario

Can a builder really sue me for more than my deposit if I don't close on my pre-construction condo?

Yes. In Ontario, deposit forfeiture is a floor, not a ceiling. If the builder resells the unit at a price below your contract price, they may sue you for the full difference, plus their carrying costs, real estate commissions, and legal fees. In Mattamy v. Ishola (2024 ONSC 6231), the court ordered the buyer to pay $87,714 in damages beyond a $60,000 forfeited deposit.

What exactly is an appraisal gap and why is my bank not covering the full purchase price?

An appraisal gap is the difference between the price you agreed to pay in your APS and the lower value a lender's appraiser assigns to the property today. Under OSFI's B-20 mortgage stress-test guidelines (which apply to federally regulated lenders), your bank can only lend against the appraised value — not the contracted price. If the appraised value is $150,000 below your purchase price, you must cover that $150,000 in cash to close. Private lenders and credit unions may apply different standards.

Is there any way to get my deposit back if I can't close on my pre-construction condo in Ontario?

Possibly, depending on the circumstances. If the builder failed to properly deliver required disclosure documents under the Condominium Act, 1998, or failed to meet Tarion addendum deadlines for closing, you may have grounds to rescind the agreement and recover your deposit. In DiCenzo v. Sadeghyar (2026 ONSC 1566), the Ontario Superior Court ordered the builder to return the full deposit when the required buyer's guide was never properly delivered. A lawyer can review your documentation to determine whether this defence applies.

Can I sell my pre-construction condo contract to someone else before closing day?

You may be able to, if your Agreement of Purchase and Sale permits assignment. An assignment transfers your contractual rights and obligations to a new buyer, allowing you to exit the deal without defaulting. Many pre-construction APS agreements either prohibit assignment or require the builder's written consent. If assignment is permitted, you typically receive either your deposit back or a premium — but the transaction must be completed before closing.

What is the builder's duty to mitigate and does it reduce what I owe?

Ontario law requires the builder to take reasonable steps to resell the unit at fair market value after you default — they cannot simply sit on the property and let damages accumulate indefinitely. In Mattamy v. Glover (2024 ONSC 4411), the court reviewed the builder's relisting strategy to confirm the duty was met. If a builder refuses a reasonable offer without justification, or delays resale unreasonably, a court may reduce the damages you owe. However, builders have considerable discretion in timing and pricing within what is considered reasonable.

What happens to my pre-construction condo HST rebate if I don't close?

If you do not close on a new construction property, you are not entitled to the Ontario new home HST rebate — because the rebate is only available to buyers who purchase and occupy (or intend to occupy) the property as their primary place of residence. If you had already factored the rebate into your closing budget, this may increase your effective financial loss. The builder is responsible for remitting HST on the sale independently of your purchase.

How long does a court judgment from a builder lawsuit stay on my credit report in Canada?

A court judgment in Ontario typically remains on your credit bureau for six to seven years from the date it is entered. During that time, it may significantly affect your ability to obtain a mortgage, car loan, line of credit, or rental housing. The judgment may also be renewed by the creditor, extending the enforcement period. A builder may enforce a judgment by garnishing your wages or seizing funds from your bank account under Ontario's enforcement rules.

Can the builder delay my closing date again after it has already been delayed several times?

This depends entirely on your Tarion addendum and the Statement of Critical Dates within it. The Tarion Addendum (issued by Tarion Warranty Corporation) requires builders to specify a firm occupancy date and sets strict limits on how many times and under what circumstances a closing can be delayed. If the builder has exhausted its permitted delays under the addendum and pushes the date further, the buyer may have a legal right to terminate the APS and recover all deposits paid. Review your addendum dates carefully with a lawyer.
