TL;DR: What's actually at stake when an appraisal gap kills your closing
An appraisal gap is the difference between the price a buyer agreed to pay and the lower value the lender's appraiser assigns.
In the 2026 Ontario market, it's a top reason deals fall apart on closing day. If the buyer can't cover the shortfall in cash and walks away, the seller can usually keep the deposit AND sue for additional damages. That second piece is where buyers get hurt the most.
The deposit is just the floor of buyer exposure, not the ceiling.
On a typical $1,000,000 GTA deal, a buyer who walks can be on the hook for the 5% deposit ($50,000), plus the resale shortfall (often $50,000 to $200,000 or more if the property closes lower), plus carrying costs like mortgage interest, property taxes, and utilities (commonly $5,000 to $20,000), plus legal fees, re-listing costs, and a second real estate commission ($15,000 to $40,000). Ontario courts generally enforce all of these against the breaching buyer when the seller can document them.
Read on for what to do if your deal is wobbling.
What is an appraisal gap, in plain language?
You agree to buy a house for $1,000,000. Your lender sends an appraiser. The appraiser comes back at $920,000.
Banks lend against the appraised value, not the contract price. So now you're $80,000 short on top of your down payment. If you can't bring that extra cash to the table, financing collapses and the deal can die on closing day.
That's the gap. It's becoming routine in 2026 because lender valuations are adjusting faster than buyer expectations. Prices people happily paid in 2022 don't always pencil out today.
Why is this hitting harder in Ontario in 2026?
A few things are stacking at once. Resale prices in parts of the GTA (Vaughan, Markham, Richmond Hill, Aurora, Newmarket, North York, Scarborough, Etobicoke) have softened from their 2022 peaks. Appraisers pull fresh comparables that reflect current sales. Buyers who waived financing conditions in firmer offers, or who locked in pricing on preconstruction units years ago, are now the ones getting squeezed hardest.
The result: contract prices are sometimes tens of thousands above what the lender will actually fund, with closing days away.
What happens legally if a buyer can't close in Ontario?
Under Ontario law, when a buyer breaches an Agreement of Purchase and Sale by failing to close, the seller can usually keep the deposit AND sue for additional damages. That's not a worst-case scenario. That's the default starting point.
Disputes are heard in the Ontario Superior Court of Justice. Judges look at proportionality, fairness, and whether forfeiture would be unconscionable. Relief from forfeiture exists, but it's discretionary and rare. Ontario courts treat the deposit as something the buyer chose to put at risk by signing the agreement.
We've covered the case law in detail elsewhere. If you want the precedent, start with our breakdown of Singh and Kaur v. Feneich, which spells out what happens to a buyer who waives the financing condition and then can't get a mortgage. Read Zoleta v. Singh for what a seller can do the moment a buyer looks shaky, including a direct discussion of low appraisals and renegotiation. Pre-construction buyers in particular should read VanderMolen Homes v. Mani, which deals with expectation damages on a builder deal that fell through.
What does a buyer actually lose? A worked example
Let's run the numbers on a realistic GTA case.
You agree to buy at $1,000,000. You put down a 5% deposit ($50,000). The appraisal comes in at $880,000. You can't bring the extra cash and you walk.
The seller relists. Three months later, the property closes at $850,000. Here's the math a seller can put in front of an Ontario judge.
The resale shortfall is $150,000 (the original $1,000,000 contract minus the $850,000 actual close). Add roughly $9,000 in mortgage interest the seller carried during the three-month delay, plus around $3,500 in property taxes and utilities they kept paying. Re-listing fees, marketing, and the second real estate commission run another $30,000 or so. Legal fees are typically another $12,000.
That's $204,500 in damages. The buyer's $50,000 deposit gets credited against it, which still leaves about $154,500 the seller can pursue against the buyer personally.
In other words: the deposit was $50,000. The exposure was over $200,000. Buyers who think "worst case I lose my deposit" are missing the bigger half of the picture.
What can sellers actually recover?
Sellers can typically recover, with proper documentation:
- The deposit, as liquidated damages
- The difference between the contract price and the eventual resale price
- Mortgage interest carried during the delay
- Property taxes and utilities the seller kept paying
- Reasonable legal fees
- Re-listing fees, marketing costs, and the second real estate commission
Sellers also have a duty to mitigate. They can't sit on the property and let damages balloon. They have to take reasonable steps to relist and resell. What's "reasonable" depends on the property, the market, and timing. Courts scrutinize this.
What to do if your deal is wobbling: the first 48 hours matter most
If you're staring at a low appraisal with closing days away, the next two days shape the rest of the case.
Ask for an extension. Sellers don't always say yes, but a short extension can buy time to find money or a workable lender. Get it in writing through your real estate lawyer. Verbal extensions rarely hold up.
Explore alternative financing. Bridge loans, second mortgages, and private lending exist for exactly this scenario. Rates aren't pretty. A 12-month bridge is still cheaper than a six-figure damages claim two years later.
Get a litigation lawyer involved early. The first calls and emails after a failed closing tend to shape the whole case. Don't draft your own cover-your-tracks email at 11pm. What you say (and what you don't) becomes evidence.
Document everything. Save every appraisal, lender email, broker conversation, and timeline. If you end up in court, the buyer who can prove they tried to close in good faith does meaningfully better than the one who can't.
The lesson, said plainly
Appraisal gaps aren't a paperwork problem. They're a financing problem with legal consequences attached. If you're buying in Ontario in 2026, build the gap into your stress test before you sign. Ask your mortgage broker what happens if the appraisal comes in 5% low. 10% low. Have an answer ready.
The buyers who get hurt aren't reckless. They just assumed the bank would see the home the way they did. In this market, that's not a safe assumption.
If you're already in a deal that's looking shaky, talk to your real estate lawyer today. Not next week. Today.
FAQ: Ontario appraisal gaps in 2026
What is an appraisal gap in real estate?
An appraisal gap is the difference between the price a buyer agreed to pay in the Agreement of Purchase and Sale and the lower value assigned by the lender's appraiser. The bank lends against the appraised value, so the buyer either covers the shortfall in cash or risks losing financing.
Can I walk away from a real estate deal in Ontario if the appraisal is low?
You can, but it's expensive. A low appraisal on its own is not a legal "out" unless your offer included a financing condition that's still active. If you walk, the seller can usually keep your deposit and sue you for additional damages, including any resale shortfall and carrying costs.
Will I lose my deposit if I can't close because of an appraisal gap?
Most likely, yes. Ontario courts generally enforce deposit forfeiture when a buyer breaches the Agreement of Purchase and Sale. Relief from forfeiture is the exception, not the rule, and judges look at proportionality and fairness on a case-by-case basis.
Can a seller sue me for more than the deposit?
Yes. If the seller relists at a lower price, the buyer can be on the hook for the difference, plus mortgage interest, property taxes, utilities, legal fees, marketing costs, and a second real estate commission. The deposit is the floor of exposure, not the ceiling.
What is the seller's duty to mitigate after a failed closing?
The seller has to take reasonable steps to resell the property and limit damages. They can't sit on the property indefinitely. What's reasonable depends on the market, the property, and the timing. Courts examine this closely when calculating final damages.
How long do failed closing disputes take in Ontario?
Most failed closing claims take 12 to 24 months to resolve, depending on the court schedule, the complexity of damages, and whether the parties settle. The Ontario Superior Court of Justice has handled a rising volume of these cases since 2024.
Can I get out of the deal with a financing condition?
If your offer was conditional on financing and the condition is still active, you can typically walk without forfeiting your deposit. Once that condition is waived or has expired, you're on the hook to close. This is exactly why waived financing conditions in hot-market bidding wars are now backfiring on so many GTA buyers in 2026.
