Understanding the Ontario Agreement of Purchase and Sale

The Blueprint of an Ontario Real Estate Deal: Purpose and Structure

When you buy or sell a home in Ontario, the transaction is governed by a legally binding contract known as the Agreement of Purchase and Sale (APS). In December 2023, the province overhauled real estate rules under the Trust in Real Estate Services Act (TRESA), replacing the old Real Estate and Business Brokers Act (REBBA) to strengthen consumer protection, enhance transparency, and update representation standards.

While custom contracts are legally permitted, nearly all residential resale transactions in Ontario use standard forms created by the Ontario Real Estate Association (OREA):

• OREA Form 100: The standard agreement for freehold residential properties, including detached homes, semi-detached houses, and freehold townhouses.

• OREA Form 101: The specialized agreement for condominium resale suites, containing specific clauses for condo corporations, common elements, maintenance fees, status certificates, and exclusive-use parking and locker allocations.

• OREA Form 500: The standard form deployed for commercial and industrial real estate trades.

An OREA Form 100 includes 29 pre-printed clauses establishing baseline legal terms, from title searches to insurance and closing adjustments. The real customization happens in Schedule A, where real estate professionals draft custom conditions, representations, warranties, and payment terms.

Crucially, Ontario resale real estate has no mandatory cooling-off period. Once both buyer and seller sign the contract and written acceptance is communicated, it is a legally binding commitment that requires both parties to perform in good faith.

Purchase Price, Deposits, and the 24-Hour Reality

The purchase price is the headline number that anchors your mortgage financing, land transfer tax calculations, and closing disbursements. Tied directly to that number is the buyer’s earnest money deposit, typically between 2% and 5% of the purchase price in Southern Ontario.

The deposit is held "in trust" by a designated stakeholder (almost always the listing brokerage) in a segregated real estate trust account. Under TRESA, deposits held by licensed brokerages are backed by the Real Estate Council of Ontario (RECO) Consumer Deposit Insurance program, protecting funds up to $200,000 per claim against brokerage insolvency or fraud.

A major legal myth exists around the deposit delivery timeline:

• The 24-Hour Rule: Standard pre-printed wording states that a deposit marked "upon acceptance" must be delivered within 24 hours of binding agreement, unless an alternate timeline is specified in Schedule A.

• The Dangerous Misconception: Many buyers assume that if they fail to wire or deliver the bank draft within 24 hours, the contract automatically dies and they can simply walk away.

• The Legal Reality: Failing to provide the deposit within 24 hours does not void the agreement. Instead, it places the buyer in fundamental breach of contract. The seller has the immediate legal right to cancel the deal, re-list the property, and sue the defaulting buyer for the difference if the home sells for less to someone else, plus all carrying costs and legal fees.

Schedule A Conditions: Safeguards and Exit Strategies

A conditional offer contains "conditions precedent", protective clauses that pause full legal performance until specific terms are satisfied or waived.

• Financing Condition & The Appraisal Gap: A standard financing clause gives the buyer 3 to 5 business days to confirm formal mortgage approval. Having a pre-approval in hand before offering is essential, but it is not a guarantee. Lenders still send an independent appraiser to confirm the home is worth what you agreed to pay. If the property appraises for less than your contract price (an appraisal gap), the lender will base their loan on the lower appraised value. Without a financing condition, the buyer must make up the cash shortfall out of pocket or face default on closing day.

• Home Inspection Condition: This allows a certified home inspector to evaluate the property's structural, electrical, mechanical, and plumbing systems. When drafted with "sole and absolute discretion," Ontario legal precedent gives the buyer wide personal latitude to walk away or negotiate repairs based on genuine inspection findings, provided they acted honestly and in good faith.

• Condominium Status Certificate Review: For condo purchases, Schedule A routinely includes a condition allowing the buyer’s lawyer 3 to 5 business days to review the condo corporation’s status certificate. This review scrutinizes the health of the reserve fund, special assessments, pending lawsuits, maintenance fee arrears, and confirms that parking spaces and storage lockers in the agreement match the registered condominium declaration.

• Sale of Buyer’s Property (SBP) & The Escape Clause: When a buyer must sell their current home to fund the purchase, an SBP condition provides that protection. In return, sellers almost always insert an Escape Clause (typically 24 to 72 hours). If the seller receives another acceptable offer while waiting, they trigger the escape clause, giving the first buyer a set window to either waive their SBP condition or let the deal terminate so the seller can accept the new buyer.

To firm up the transaction, the benefiting party delivers a Notice of Fulfillment (OREA Form 124) or a Waiver (OREA Form 123) before the deadline. If a condition cannot be met despite good-faith efforts, the agreement terminates and the buyer’s full deposit must be returned without penalty or deduction.

Firm vs. Conditional Offers: Legal Precedents and Buyer Liabilities

In a competitive seller's market, buyers often feel pressured to submit "firm offers" (offers with zero conditions) to make their bid stand out. In balanced or buyer-leaning markets, conditional offers are standard practice.

Understanding the consequences of walking away from a firm deal is critical. In Ontario courts, forfeiting your deposit is a legal floor, not a ceiling:

• Loss of Bargain Damages: When a buyer backs out of a firm purchase, the seller is entitled to retain the deposit as liquidated damages without having to prove financial injury. If the seller ends up selling the home to another party at a loss, the defaulting buyer is personally liable for the difference.

• Gamoff v. Hu (Ontario Superior Court of Justice): The court ruled that buyers who submitted a winning bid during a market peak and subsequently failed to secure mortgage financing were fully liable for the substantial price drop when the property was resold in a cooler market.

• Mattamy (Jock River) Ltd. v. Ishola (Ontario Superior Court of Justice): The court ordered a defaulting purchaser to pay an $87,714 resale price shortfall in addition to forfeiting their $60,000 deposit, creating an overall financial loss of nearly $150,000.

• Tallman v. Miller (Ontario Superior Court of Justice): The court confirmed that even when a buyer never paid the required $280,000 deposit after signing, the contract was legally binding. The court granted default judgment against the buyer for market losses, carrying costs, and legal expenses.

Defaulting buyers are also held accountable for the seller’s carrying costs during the resale period, including ongoing mortgage interest, property taxes, utilities, and additional legal and staging fees.

Critical Deadlines: Irrevocable Periods and Title Requisition Dates

Ontario real estate contracts enforce the legal principle that "time shall be of the essence." Missing a contractual deadline by minutes can terminate your rights or place you in breach.

• The Irrevocable Date and Time: This clause specifies the exact date and hour until which an offer remains open for acceptance. During this window, the party making the offer cannot withdraw it. If the other party does not sign and deliver written acceptance before the clock runs out, the offer dies automatically. Secure electronic signatures (such as DocuSign) are recognized as legally binding under Ontario’s Electronic Commerce Act.

• Clause 8: The Requisition Date (Title Search): Typically set 15 to 25 days before closing, this is the deadline for the buyer’s lawyer to complete land registry searches and send formal written requisitions (objections) to the seller’s lawyer. This search verifies that title is clean, checks for un-discharged mortgages, tax liens, open building permits, and municipal work orders. If a buyer's lawyer misses this deadline, the buyer may be legally forced to accept title with existing defects.

Fixtures, Chattels, and Rented Equipment

Misunderstandings about what stays with the house are among the most common closing-day disputes:

• Fixtures (Stay with the Property): Items physically attached to the property by nails, screws, pipes, or wiring, such as built-in cabinetry, light fixtures, bathroom mirrors, and furnaces. Fixtures are legally presumed to be included unless explicitly excluded in the contract.

• Chattels (Go with the Seller): Movable personal property, such as refrigerators, stoves, washers, dryers, and patio furniture. Chattels are excluded unless explicitly listed as included in Schedule A.

• Rental Items (Require Written Assumption): Essential home equipment that is leased rather than owned, such as hot water tanks, water softeners, propane tanks, or solar panel systems. The contract must identify every rental contract the buyer agrees to take over. If an item is omitted, the seller is legally obligated to buy out the contract and clear the equipment lien before closing.

Closing Mechanics, Spousal Consent, and Closing Surprises

On closing day, legal ownership transfers electronically via Teraview under the Law Society of Ontario's Document Registration Agreement, mortgage funds disburse, and keys are released.

Key closing safeguards to be aware of:

• Matrimonial Home & Spousal Consent: Under Section 22 of the Ontario Family Law Act, if a property is occupied as a family residence, a non-titled spouse holds equal possession rights. Even if only one spouse is on the title, the other spouse must sign the Spousal Consent section of Form 100. Without it, the seller cannot transfer clear title, putting the entire sale in legal jeopardy.

• Harmonized Sales Tax (HST): Resale residential properties are exempt from HST. However, HST applies to new construction, substantial renovations, or properties used for commercial activities. The contract must state whether HST is "included in" or "in addition to" the purchase price.

• Non-Resident Speculation & Withholding Taxes: If a seller is a non-resident of Canada under Section 116 of the Income Tax Act, the buyer’s lawyer must ensure a CRA Certificate of Compliance is obtained. Without it, the buyer’s lawyer is required by law to withhold a substantial portion of the sale proceeds to prevent the buyer from becoming liable for the seller’s unpaid taxes.

5 Common Contract Pitfalls to Avoid

1. Treating deposit deadlines casually: Always have your deposit funds liquid and accessible within 24 hours of signing.

2. Writing vague condition clauses: Avoid subjective phrases like "upon buyer being satisfied" without specifying how satisfaction is proved, who pays for inspections, and exact delivery deadlines.

3. Overlooking the Requisition Date: Ensure your lawyer has enough runway to complete full municipal and title searches before the Clause 8 deadline.

4. Failing to list specific appliances: Don't just write "all appliances included"; list them by brand, type, and serial number where possible.

5. Skipping legal review on condo status documents: Never waive a status certificate review without having a real estate lawyer evaluate the reserve fund and corporate bylaws.
