Realty Brokers and Realty Buyers and Arguments of Enforceability

Question: If I signed an OREA Form 300 Buyer Representation Agreement in Ontario and then bought through another brokerage, do I still owe commissions?
Answer: SFG Paralegal Services LLP can explain how Ontario’s OREA Form 300 Buyer Representation Agreement typically works, and generally a buyer must pay commission to the represented brokerage if the buyer acquires a property during the agreement’s term, even when the purchase is facilitated by another realty broker, because the BRA commission clause commonly entitles the brokerage to retain any commission offered by the listing brokerage or the seller; if you are trying to avoid paying based on an alleged oral change or “it was just a formality,” courts often apply the parol evidence rule, meaning an unwritten or purely verbal variation usually cannot override the clear written terms, so the outcome depends on the exact contract wording, dates, and the transaction facts; for a practical review of your BRA, transaction timeline, and listing communications, call (888) 398-0121 to speak with a paralegal at SFG Paralegal Services LLP.

Is a Buyer Under a Broker Representation Agreement (OREA Form 300) Liable For Commissions If the Buyer Acquires a Property Through Another Realty Broker?
A Buyer Under a Live Broker Representation Agreement Must Pay Commission to the Broker Even If the Buyer Acquires Property through a Different Broker Whereas Such Is, Among Other Issues, a Specific Purpose of a Broker Representation Agreement.
Understanding the Enforceability of Broker Representation Agreements Involving the Ontario Real Estate Association Form 300
In Ontario, the OREA Form 300, known as a Broker Representation Agreement, is a contract between a potential buyer and a realty brokerage that is generally applicable to a geographical area and a limited time period. Legal disputes arising from alleged breach of a Broker Representation Agreement are common, especially within the Small Claims Court as commissions allegedly payable often falls within the current thirty-five thousand 00/00 ($35,000.00) dollar per Plaintiff monetary jurisdiction of the Small Claims Court. Interestingly, the common outcome for such cases is mixed whereas Broker Representation Agreement cases involve legal issues that are often highly dependent upon the unique facts of each case.
The Law
A common example of commission disputes under a Broker Representation Agreement is found in the Sun v. Mani, 2024 CanLII 35486, case wherein it was stated:
The Law Surrounding the Buyer Representation Agreement (OREA FORM 300)
[22] Disputes surrounding the Buyer Representation Agreement (hereinafter “BRA”) are frequent visitors to the Superior Court and the Small Claims Court.
[23] The front page of the BRA dictates the following, “The Buyer hereby gives the brokerage the exclusive and irrevocable authority to act as the Buyer’s agent commencing at 9 a.m. on the 3rd day of May, 2021 and expiring at 11:59 p.m. on the 31 day of August, 2021.”
[24] On the portion for commission, it reads (my emphasis added):
2. COMMISSION: In consideration of the Brokerage undertaking to assist the Buyer, the Buyer agrees to pay commission to the Brokerage as follows: If, during the currency of this Agreement, the Buyer enters into an agreement to purchase or lease a real property of the general description indicated above, the Buyer agrees the Brokerage is entitled to receive and retain any commission offered by a listing brokerage or by the seller. The Buyer understands that the amount of commission offered by a listing brokerage or by the seller may be greater or less than the commission stated below. The Buyer understands that the Brokerage will inform the Buyer of the amount of commission to be paid to the Brokerage by the listing brokerage or the seller at the earliest practical opportunity. The Buyer acknowledges that the payment of any commission by the listing brokerage or the seller will not make the Brokerage either the agent or sub-agent of the listing brokerage or the seller.
If, during the currency of this Agreement, the Buyer enters into an agreement to purchase any property of the general description indicated above, the Buyer agrees that the Brokerage is entitled to be paid a commission of 2.5% of the sale price of the property or [as per MLS] (entered term).
The Buyer agrees to pay directly to the Brokerage any deficiency between this amount and the amount, if any, to be paid to the Brokerage by a listing brokerage or by the seller. The Buyer understands that if the Brokerage is not to be paid any commission by a listing brokerage or by the seller, the Buyer will pay the Brokerage the full amount of commission indicated above.
During the Sun proceedings, the buyer put forth the argument that the written Broker Representation Agreement included an unwritten verbal clause or was later changed by a separate oral agreement. Acceptance of such an argument was denied by the court based upon the parol evidence rule which exists to safeguard certainty of contracts. Should an person, such as the Defendant in Sun, wish to successfully argue against the written applicability of a Broker Representation Agreement by virtue of a term extraneous to the express terms within the Broker Representation Agreement, demonstrable written alteration of the Broker Representation Agreement would be imperative whereas the operation of the parol evidence rule thwarts attempts to override written contracts with purported oral contract terms. The application of the parol evidence rule within the Sun case referenced and cited Fung v. Decca Homes Limited, 2019 ONCA 848, which states:
[5] We see no error in the application judge’s application of the parole evidence rule in the circumstances of this case: Hawrish v. Bank of Montreal, 1969 CanLII 2 (SCC), [1969] S.C.R. 515, at p. 520. Even if there was a collateral oral agreement, something that is disputed by the respondent, that oral agreement could not contradict the written agreement. ...
Within cases disputing the enforceability of a Broker Representation Agreement, such as Sun, which among other cases cited Apex Results Realty Inc. v. Zaman, 2018 ONSC 7387, and First Contact Realty Ltd. v. Prime Real Estate Holdings Corporation, 2015 ONSC 5511, it is shown that the written terms within a Broker Representation Agreement will stand strong unless there exists an amendment in writing. In this respect, these cases all similarly state:
[35] In our matter, Mr. Mani alleges that Mr. Sun stated to him that the BRA was only a “formality” and that it would not enforced. This appears to me to be a modification of the fundamental terms and conditions of the contract. There is also no evidence in writing of this oral representation. The Parole Evidence Rule is applicable here, which holds that evidence of an oral agreement cannot prevail over the clear written contractual terms.[3]
[36] In Apex Results Realty Inc. v. Zaman, 2018 ONSC 7387[4], the brokerage brought a summary judgment motion in Superior Court for payment of commissions owed on two separate properties during the effective representation period of the BRA. Justice Turnbull ruled in the brokerage’s favour citing the terms of the BRA indicated that commission was payable to the brokerage by the buyer if the buyer purchased a property during the currency of the BRA.[5] In coming to his decision, Justice Turnbull cited a decision of Justice Healey in First Contact Realty Ltd. v. Prime Real Estate Holdings Corp., 2015 ONSC 5511. This was yet, another summary judgment motion wherein the Defendant buyer alleged that there was an oral agreement to terminate the BRA. Both Justice Healey and Justice Turnbull, in their requisite decisions cited application of the Parole Evidence Rule, restricting evidence of oral evidence in the face of a clearly written and executed contract between parties. Justice Turnbull’s decision was appealed and it was upheld by the Court of Appeal in Apex Results Realty Inc. v. Zaman, 2019 ONCA 766[6].
[53] The parole evidence rule exists to help parties avoid this type of allegation being made by a contracting party. It effectively precludes the admission into evidence of words which would vary or contradict the terms of a written contract between the parties. Without it, it would almost be impossible to have finality or certainty in contractual relations. It further limits the ability of a party to fabricate evidence to vary or change the terms of a written contract. The parole evidence rule centres the court’s attention on the contract and what the parties have reduced to writing. It creates contractual clarity and certainty.
[25] This evidence is insufficient to establish the essential elements of an agreement, as it lacks any specificity with respect to the terms of such agreement, as well as failing to outline the consideration for entering into such an agreement. Hinn provides no details in his affidavit, or elsewhere, of the particulars of such an exchange of ideas leading to the parties forming an intention to terminate the Buyer Representation Agreement. The details are lacking of when, where, how and why such alleged discussions took place.
For a buyer attempting to escape the enforcement of a Broker Representation Agreement, the buyer will, generally, need to prove that Broker Representation Agreement was founded upon improper, and perhaps illicit, statements by a realty agent. The buyer seeking to achieve this endeavour will require the demonstration of a failure to adhere to contract formation principles so to depict a scenario more severe than simple regret.
Conclusion
A Broker Representation Agreement (OREA Form 300) is a standard and common contract used within the business of real estate dealings. As a contract, the general rules and principles of contract law apply; and as such, making a case that a Broker Representation Agreement is without binding effect and is unenforceable requires proof of factual circumstances that fall within the realm of general contract law. The fact that the Broker Representation Agreement is specific to the realty business fails to make such a contract unusually special and, generally, enforceability of the Broker Representation Agreement is subject to usual contract law principles.
