How to Handle a Breach of Agreement of Purchase and Sale in Vaughan

💡

If a buyer or seller refuses to close a real estate transaction in Vaughan, it is a severe breach of contract. The innocent party must legally “tender” on closing day to prove they were ready, and then immediately hire a real estate litigation lawyer to sue for financial damages at the Superior Court of Justice.

Buying or selling a home in Vaughan is a high-stakes transaction. When both parties sign the Agreement of Purchase and Sale (APS), it is a legally binding contract. Unfortunately, sudden drops in housing prices or failed mortgage approvals sometimes cause buyers to panic and walk away. Other times, a seller might refuse to hand over the keys because they feel they sold the home too cheaply.

Failing to close on the agreed date is a breach of contract that carries massive financial consequences. 💵 Whether you are the buyer or the seller, you cannot simply shrug and move on. The innocent party is entitled to seek compensation for the deposit and the difference in property value. This guide outlines the exact legal steps required to protect yourself when a real estate deal collapses in Ontario.

Step-by-Step Process in Vaughan, Ontario

Real estate litigation in York Region is typically handled at the Newmarket courthouse (Superior Court of Justice). The actions you take on the actual day of closing are the most critical part of your future lawsuit. Here is how you must handle the crisis.

Step 1: Tender on Closing Day

If you suspect the other party will not close, your real estate lawyer must “tender” the transaction. Tendering is the legal act of proving that you were 100% ready, willing, and able to close the deal on the specified day. For a buyer, this means showing you had the mortgage funds ready in your lawyer’s account. For a seller, it means sending the signed deed and keys to the buyer’s lawyer. Without tendering, a judge may rule that neither side was ready.

Step 2: Refuse to Sign a Mutual Release (Initially)

When a buyer backs out, their real estate agent will often rush over a “Mutual Release” document. 🚫 Do not sign this without speaking to a litigation lawyer. Signing a mutual release completely kills the contract, meaning the buyer gets their deposit back and you lose your right to sue them for damages. The deposit should remain frozen in the brokerage’s trust account until the dispute is resolved.

Step 3: Mitigate Your Damages

If you are the seller and the buyer breaches, Canadian law requires you to “mitigate” (minimize) your financial losses. You must put the Vaughan property back on the market as soon as possible and try to get the best possible price. If the original buyer offered $1,000,000, and the best new offer you get is $850,000, you can sue the original buyer for that $150,000 shortfall, plus extra carrying costs.

Step 4: File a Statement of Claim

Once your final damages are calculated, your litigation lawyer will file a Statement of Claim against the defaulting party. 📄 You will demand the forfeiture of the deposit and the total sum of your lost value, legal fees, and moving expenses. If you are a buyer whose seller refused to close, your lawyer can also file for “Specific Performance,” asking the judge to force the seller to hand over the property.

How Much Does Real Estate Litigation Cost?

Suing someone for a breach of contract is an expensive and complex civil procedure. You must carefully weigh the costs of litigation against the amount you hope to recover. Here are the typical legal fees in CAD:

Legal ServiceEstimated Cost (CAD)Description
Demand Letter & Negotiation$750 – $1,500Lawyer attempts to settle the dispute out of court or negotiate a partial release of the deposit.
Starting the Lawsuit (Retainer)$5,000 – $10,000Upfront fee to draft the Statement of Claim and formally begin the litigation process.
Full Trial at Superior Court$25,000 – $50,000+Extensive costs for pre-trial discoveries, expert appraisals, and days spent in a courtroom.

How Long Does the Process Take?

Civil litigation moves very slowly. ⏳ If the defaulting party is reasonable, your lawyer might negotiate a settlement in 3 to 6 months. However, if the matter goes all the way to a full trial at the Superior Court of Justice, it is entirely normal for the process to take 2 to 4 years before a judge renders a final decision.

Frequently Asked Questions (FAQ)

Who gets to keep the deposit if the buyer walks away?

The deposit sits in the real estate brokerage’s trust account. It can only be released if both parties sign a mutual release, or if a judge issues a court order. Generally, if the buyer breaches, the seller is entitled to keep the deposit.

What if the buyer failed to get a mortgage?

Unless the Agreement of Purchase and Sale contained a specific “Condition of Financing” that was not yet waived, failing to get a mortgage is not a valid legal excuse to cancel a firm deal. The buyer is still fully liable for the breach.

Can I back out if the home inspection was bad?

If your contract had a conditional period for a home inspection, you can back out during that specific timeframe. If you already waived the conditions and the deal is firm, discovering a defect later does not allow you to walk away.

What is a Certificate of Pending Litigation (CPL)?

If a seller refuses to close, the buyer’s lawyer can register a CPL on the title of the Vaughan property. This acts as a massive red flag, legally preventing the seller from selling the home to anyone else while the lawsuit is ongoing.
