If an Ontario commercial real estate broker secretly represents both the buyer and the seller in a transaction, they have committed a severe breach of fiduciary duty. You can sue the brokerage in the Superior Court of Justice to demand the disgorgement (return) of all commissions paid and seek damages for your financial losses.
The Dangers of Undisclosed Dual Agency in Ontario
Commercial real estate transactions in cities like Hamilton, London, or Vaughan often involve millions of dollars. Whether you are an investor buying a warehouse or a corporation selling an office plaza, you rely heavily on your real estate broker to secure the best possible price. By law, your broker owes you a strict fiduciary duty of undivided loyalty, confidentiality, and full disclosure. 💵
“Dual agency” (now legally referred to as multiple representation under Ontario’s Trust in Real Estate Services Act, or TRESA) occurs when one brokerage represents both sides of the deal. While this is legal if fully disclosed and consented to in writing, doing it secretly is a massive violation. An undisclosed dual agent is inherently conflicted, often pushing for a quick closing rather than protecting your financial interests. If you discover your broker was secretly playing both sides, retaining a business litigation lawyer from our directory is essential to hold them accountable. ⚖
Step-by-Step Process: Litigating Broker Misconduct
Taking legal action against a licensed real estate professional involves both regulatory complaints and civil litigation. Here is the standard procedure for holding a rogue broker financially liable in Ontario. 📝
Step 1: Gather Evidence of the Conflict
Before launching a lawsuit, your lawyer needs proof that the broker was secretly advising or representing the other party. This often surfaces after the deal closes, through leaked emails, text messages, or discovering that the buyer/seller had a prior, ongoing financial relationship with your agent that was never disclosed to you. 📄
Step 2: File a Complaint with RECO
You should formally report the broker to the Real Estate Council of Ontario (RECO), the provincial regulator. A RECO investigation can lead to the broker being fined, suspended, or having their license revoked. While RECO cannot force the broker to pay you civil damages, their investigative findings serve as powerful evidence in your civil lawsuit. 🚨
Step 3: Issue a Statement of Claim
Your lawyer will draft a Statement of Claim to file in the Superior Court of Justice. The lawsuit will name both the individual agent and their Brokerage. The primary legal arguments are breach of fiduciary duty, negligent misrepresentation, and potentially civil fraud, focusing heavily on how the secret conflict negatively impacted the final purchase price. 📧
Step 4: Demand Disgorgement and Damages
In court, your lawyer will seek “disgorgement.” This is an equitable remedy where the judge orders the broker to forfeit and return the entire commission they earned from the tainted deal, regardless of whether you suffered a specific financial loss. Additionally, if you overpaid (or undersold) because of their bad advice, you will sue for compensatory damages to cover the difference. 💰
How Much Does It Cost to Sue a Commercial Broker?
Commercial real estate litigation is complex and heavily contested, as the broker’s professional liability insurance (Errors & Omissions) will hire aggressive defence lawyers. As of May 2026, you should prepare for the following costs. 💵
| Legal Action | Estimated Cost in CAD |
|---|---|
| RECO Regulatory Complaint | Free. You do not pay to file a complaint with the provincial regulator. |
| Pre-Trial Litigation & Discovery | Hourly lawyer fees for discoveries and motions usually cost $15,000 to $35,000 CAD. |
| Full Superior Court Trial | Taking a breach of fiduciary duty case to a final verdict can exceed $50,000 to $100,000 CAD. |
How Long Does the Process Take?
Holding a professional accountable takes significant time. A RECO investigation can take 6 to 12 months to conclude. In the civil courts, proceeding from the initial Statement of Claim to a final trial date usually takes 2 to 3 years. Fortunately, the threat of losing their license and massive legal costs often pushes brokerages to settle during mandatory mediation, which can shorten the timeline to 12 to 18 months. ⏳
Frequently Asked Questions (FAQ)
What exactly is disgorgement?
Disgorgement is a court order forcing a party to give up profits they made through illegal or unethical acts. If your broker breached their fiduciary duty, the court can force them to repay the entire commission, essentially stripping them of any financial benefit from the betrayal.
Can I cancel the real estate deal because of this?
Sometimes. If you discover the dual agency before the closing date, you may have grounds to rescind (cancel) the contract. If the deal has already closed, cancelling it is extremely difficult unless you can prove the other party was actively involved in the fraud.
Is multiple representation ever legal under TRESA?
Yes, but it requires informed, written consent from all parties. Under TRESA, the broker must fully explain the risks and limitations of their services, and you must sign a specific disclosure form acknowledging the multiple representation.
Will the broker’s insurance pay the settlement?
Most real estate agents carry professional liability insurance. However, many insurance policies exclude coverage for intentional fraud or deliberate breaches of fiduciary duty, meaning you may have to seize the broker’s personal or corporate assets directly.
