How to Sue for Specific Performance in a Commercial Real Estate Dispute in Ontario

In Ontario, suing for specific performance means asking the Superior Court of Justice to legally force a seller to complete a commercial property sale. To win, you must prove the property is so unique that financial damages cannot cover your loss, and the court filing fee for a Statement of Claim is currently $320 CAD.

Buying commercial real estate in Ontario is a massive investment. Whether you are purchasing an industrial warehouse in Mississauga, a retail plaza in Ottawa, or a development lot in Toronto, you expect the seller to honour the signed contract. However, in a fluctuating market, sellers sometimes get “seller’s remorse” and try to back out of the deal, hoping to sell to a higher bidder. When this happens, a standard lawsuit for financial compensation might not be enough. 🏢

Instead of just walking away with damages, you can ask the court for an equitable remedy called “specific performance.” This legal order forces the seller to transfer the title of the property to you exactly as agreed in the Agreement of Purchase and Sale (APS). However, Ontario courts do not grant this remedy easily. You must prove that the commercial property is truly unique and irreplaceable for your business needs. If you find yourself in this situation, it is highly recommended to reach out to a commercial litigation lawyer from our directory to protect your deposit and your rights.

Step-by-Step Process for Specific Performance in Ontario

Litigating a commercial real estate dispute requires rapid action. If the seller manages to sell the property to a third party before you file your claim, specific performance becomes practically impossible. Here is how the process generally unfolds in the Superior Court of Justice.

Step 1: Review the Agreement of Purchase and Sale (APS)

Before taking legal action, your law firm must carefully review the original APS. They will check if all conditions (like financing or environmental inspections) were properly waived or fulfilled on time. If you missed a deadline, the seller might have had the legal right to terminate the deal. You must ensure you have a completely clean, binding contract with no outstanding “escape clauses” for the seller. 📜

Step 2: Tender Performance on the Closing Date

This is a critical legal maneuver in Ontario. To sue the seller for breaching the contract, you must prove that you were ready, willing, and able to close the deal. This is called “tendering.” Your real estate lawyer will assemble the closing funds, sign all the required mortgage documents, and officially notify the seller’s lawyer that you have the money and are waiting for the keys. If the seller fails to provide the deed, they are officially in breach.

Step 3: Issue a Statement of Claim

Once the breach is established, your commercial litigation lawyer will draft and file a Statement of Claim at the Superior Court of Justice. This document formally starts the lawsuit. It will outline the history of the transaction, the exact terms the seller breached, and will explicitly request both specific performance and financial damages in the alternative.

Step 4: Register a Certificate of Pending Litigation (CPL)

This is arguably the most important step to secure the property. A Certificate of Pending Litigation (CPL) is a legal notice registered directly on the title of the disputed property at the Ontario Land Registry Office. 🔒 Once a CPL is on title, the seller is effectively blocked from selling the property to anyone else, refinancing it, or transferring it until your lawsuit is resolved by a judge.

Step 5: Prove the “Uniqueness” of the Property

Ontario courts generally presume that commercial properties are investments and that lost profits can be compensated with money. To win specific performance, you must gather heavy evidence showing the property is uniquely suited to your business. For example, you might prove it is the only site in the municipality zoned for your specific heavy manufacturing use, or it sits on a key geographical location that your logistics company cannot replicate anywhere else.

Step 6: Proceed to Examinations for Discovery and Trial

If the seller refuses to settle, the case moves to the “Discovery” phase, where both sides exchange internal documents and conduct under-oath interviews. Ultimately, if no agreement is reached, a judge at the Superior Court will hear the evidence and decide whether to order the seller to transfer the property to you.

How Much Does it Cost in Ontario?

Commercial litigation is expensive and requires a significant budget. Below are estimated costs in Canadian dollars (CAD) for pursuing a specific performance claim:

Legal Action / ServiceEstimated Cost (CAD)Details
Court Filing Fee (Statement of Claim)$320Mandatory fee payable to the Superior Court of Justice.
Certificate of Pending Litigation (CPL)$77.30Provincial land registry fee to register the CPL on title.
Initial Lawyer Retainer$5,000 – $15,000+Upfront deposit required by a commercial litigation firm.
Full Trial Costs$30,000 – $100,000+Total legal fees if the dispute goes all the way to a final trial.

How Long Does the Process Take?

Obtaining a CPL to lock down the property can usually be done very quickly, often within 1 to 3 weeks after the breach. However, getting a final court order for specific performance is a long journey. A standard commercial real estate lawsuit in Ontario typically takes 1.5 to 3 years to reach a full trial, depending on backlogs at your local courthouse. ⌛

Frequently Asked Questions (FAQ)

Can I sue for both specific performance and financial damages?

Yes. It is standard practice for lawyers to plead in the alternative. You ask the court for the property first, but if the judge decides the property is not unique enough, you ask for financial damages to cover your lost profits and out-of-pocket expenses.

What if the seller has already sold the property to someone else?

If an innocent third party has already bought the property and registered the title without knowing about your dispute, specific performance is generally no longer possible. In this scenario, your only legal remedy is to sue the original seller for financial damages.

Is a residential home considered unique?

In Ontario, courts generally rule that ordinary residential homes in subdivisions are not unique, as you can simply buy another house nearby with your damage award. Specific performance is usually reserved for highly customized homes, properties with unique acreage, or highly specialized commercial lots.

Do I get my deposit back if I sue?

If you are suing for specific performance, your deposit generally remains locked in the real estate brokerage’s trust account until the lawsuit is resolved or the parties sign a mutual release. You cannot take your deposit back and simultaneously sue to force the sale.
