Ontario Agreement of Purchase and Sale (OREA Form 100)

This Page's Content Was Last Updated: October 15, 2026

An Agreement of Purchase and Sale (APS) sets out the terms of a real estate purchase in Ontario. It identifies the property, price, deposit, closing date and any conditions that must be addressed before the transaction becomes firm. Once an offer is properly accepted and acceptance is communicated, the agreement creates legal obligations for both the buyer and seller, subject to its terms.

OREA Form 100 is commonly used in Ontario for resale freehold homes, such as detached, semi-detached, and freehold townhouses. OREA Form 101 is commonly used for condo apartments and condo townhouses. Understanding the completed form, including every attached schedule, helps you see what you are agreeing to before you sign.

What You Should Know
  • An accepted offer is a contract. A conditional agreement also creates obligations; it is not a reservation you can cancel whenever you want.
  • Use the right form. Form 100 is commonly used for resale freehold homes, Form 101 for resale residential condos, and Form 500 for commercial property.
  • Conditions are negotiated protections. Financing, inspection and other conditions must be written into the agreement with workable deadlines.
  • A deposit is part of the purchase price. It is paid to the named deposit holder and normally credited toward the amount due on closing.
  • Check the whole agreement. Dates, inclusions, rental contracts, tax wording, signatures and Schedule A can all affect your obligations.

This guide provides general information about Ontario resale agreements. Have an Ontario real estate lawyer review the terms and any proposed waivers.

OREA Form 100 vs Form 101 vs Form 500

OREA stands for the Ontario Real Estate Association. It publishes standard forms used by Ontario real estate professionals, including members of the Toronto Regional Real Estate Board (TRREB).

FormCommon useWhat to focus on
Form 100Resale freehold homes, such as detached houses and freehold townhousesLand description, inclusions, rentals, conditions and closing terms
Form 101Resale residential condominiums, including condo townhousesUnit, parking and locker details; condo fees; status certificate review
Form 500Commercial propertyPermitted use, leases, environmental review, HST and commercial due diligence

The property's ownership structure matters more than its appearance: a townhouse may be freehold or condominium. New homes purchased from builders usually involve builder agreements and additional documents. A condo resale form should not be treated as a substitute for a pre-construction agreement.

Is OREA Form 100 Mandatory?

OREA Form 100 is not legally required for the purchase and sale of a resale freehold home in Ontario, but it is the standard form used in most transactions involving detached, semi-detached, and freehold townhouse properties.

These standardized forms are widely used because the Ontario Real Estate Association has developed them to address the key terms, obligations, protections, and legal considerations that commonly arise in a real estate transaction. A real estate professional who chooses to use a customized agreement instead may take on additional risk and potential liability if important provisions are omitted or drafted incorrectly.

That does not mean buyers and sellers should sign the forms without understanding them. A real estate professional should explain the agreement, including any schedules and conditions, and provide clarification where needed. The clauses in these forms are there for a reason, and understanding what each one means helps buyers and sellers know exactly what they are agreeing to before they sign.

How to Read the Main Terms

Names and property details

Use the full legal names of all buyers and sellers. Check the street address and legal description, and have your lawyer confirm ownership and signing authority. If someone signs for an estate, company or another person, their authority needs to be verified. Ask whether spousal consent is required.

Purchase price and deposit

The purchase price is the agreed amount for the property. The deposit is an advance payment credited toward that price on closing; it is not an extra charge or the same thing as the total down payment.

For example, on an $800,000 purchase with a $160,000 down payment, a $40,000 deposit would normally leave $120,000 of the down payment to provide on closing, plus closing costs and adjustments. The mortgage would fund the remaining $640,000.

Specify the deposit amount, recipient, payment method and delivery deadline. There is no single deposit percentage required for every Ontario resale purchase. The standard Form 100 wording defines a deposit due upon acceptance as payable within 24 hours, unless the agreement provides otherwise. Arrange access to the money before making the offer.

Not paying the deposit does not automatically cancel an accepted agreement. It can put the buyer in breach. Missing a deposit has consequences.

Offer expiry and closing date

The irrevocability section records how long the offer is to remain open. Check the exact date, time and a.m. or p.m. designation. Do not assume you can withdraw an outstanding offer during that period; get legal advice before attempting to do so.

The completion date is the agreed closing date. Choose it with your lawyer and lender so funds, documents and possession can be arranged. A closing period of 60 or 90 days is common.

Inclusions and exclusions

Chattels are movable items, such as a freestanding refrigerator. Fixtures are attached to the property, such as a built-in light fixture. List the items that matter instead of relying on assumptions or the listing description. Identify appliances by make or model where useful, and expressly exclude any fixture the seller will remove.

If the seller promises to leave an appliance in working order, complete repairs or replace an excluded fixture, put the promise and deadline in the agreement.

Rental equipment

Identify rented or leased items, including water heaters, furnaces, air conditioners and solar equipment. Request the actual contracts and check payments, remaining terms, transfer rules and buyout costs. State whether the buyer will assume a contract, if transferable, or whether the seller must pay it out.

Title search and schedules

Give your lawyer enough time before the title search or requisition deadline to investigate the property and raise appropriate objections. It is not a promise that every possible title issue will be fixed by that date.

Read Schedule A and every other attachment. Ask for conflicting terms to be resolved before signing, and put negotiated conditions, repairs and other commitments in writing.

Firm vs Conditional Offers

QuestionFirm offerConditional offer
What does it mean?Once accepted, no negotiated conditions remain to be satisfied or waived.The accepted agreement contains conditions with specified requirements and deadlines.
Can the buyer walk away?Changing their mind is not a right to cancel.Only as permitted by a valid condition, another contract term or applicable law.
What if the mortgage is refused?The buyer generally remains responsible for closing.An active financing condition may provide an exit, depending on its wording and compliance.
What if an inspection finds problems?There is no automatic inspection-based cancellation right.The inspection condition determines the buyer's options.
Is the deposit automatically refundable?No. Buyer default can put it at risk.No. Entitlement depends on the agreement and how the condition was handled.

Both types of accepted agreements are legally binding.

The consequences of waiving financing

A mortgage preapproval does not guarantee funding for a particular property. The lender may still need to approve the appraisal, property and supporting documents. A low appraisal can leave you needing more cash than expected.

If you waive financing and cannot close, you may lose your deposit and face a claim for additional losses. Before waiving, confirm the lender's outstanding requirements and whether you can cover any funding gap.

The consequences of waiving inspection

Giving up an inspection condition means giving up that contractual protection. You may discover expensive defects after committing to the purchase. A pre-offer inspection can provide information, but it does not guarantee the property's condition or create a cancellation right.

A home inspection also does not automatically require the seller to fix everything it identifies. Repairs or a price change need agreement from both parties.

Fulfilment and waiver are different

Fulfilment confirms that a condition has been met. Waiver gives up the protection where the agreement permits it. Follow the clause's notice, signature and delivery requirements before the deadline.

Common Conditions to Consider

Conditions should explain what must happen, whose approval is required, the deadline, how notice must be delivered and what happens to the agreement and deposit if the condition is not met. Act in good faith and make the efforts the agreement requires. The following are topics to discuss with your lawyer or agent.

Financing

Allow time to obtain satisfactory financing for the specific purchase. Ask the lender to confirm the loan amount, appraisal requirements, down payment documentation and any outstanding conditions. Don’t treat a rate hold or preapproval as final approval.

Home inspection

Allow access for a qualified inspector and time to review the report. Consider whether the property also needs specialist checks, such as a well, septic system or structural assessment. The contract should describe what happens if the results are unsatisfactory. A visual inspection cannot identify every hidden defect.

Status certificate review for condos

Allow time to obtain the status certificate and supporting documents and have your lawyer review them. Focus on unit arrears, condo fees, special assessments, reserve funds, litigation, insurance and restrictions that could affect your plans.

Ontario condo corporations generally have 10 days after receiving the request and payment to provide the certificate and may charge up to $100. Build in time for delivery and legal review.

Sale of the buyer's property

Specify which property must sell, by when, and whether its sale must become firm or actually close. If you need the proceeds to fund the purchase, check that both closing dates and any bridge financing work together. Selling your home and receiving the money are different milestones.

Insurance

Consider a condition allowing you to confirm that suitable property insurance is available on acceptable terms and at an affordable premium. Obtain a home insurance quote early, particularly where the property's condition, location, prior claims or intended use could affect coverage. Ask your lender about its insurance requirements.

Lawyer review

A lawyer review condition can provide time for legal review after acceptance, if the other party agrees to it. Define its scope and deadline clearly. Hiring a lawyer after signing does not, by itself, create a right to cancel; arranging review before submitting an offer can avoid that problem.

Escape clauses

A negotiated escape clause may allow the seller to continue marketing the property and trigger a deadline for the first buyer to remove specified conditions. The clause must say how this works. Receiving a better offer does not, on its own, let the seller disregard an accepted agreement.

How Your Deposit Is Protected: Brokerage Trust Accounts and RECO Insurance

When an Ontario real estate brokerage holds your deposit, it holds the money in a real estate trust account, separate from its operating funds. The agreement should name the deposit holder and say when payment is due.

RECO's consumer deposit insurance can respond to covered losses involving brokerage theft, fraud, insolvency or misappropriation. RECO currently lists limits of $200,000 per claim and $4 million for claims arising from one event, with no deductible. If eligible claims exceed the event limit, payments may be prorated.

Insurance does not result in a refund if a purchase falls through for a reason that is not a covered loss.

What happens if the deal does not close

A properly handled condition may entitle the buyer to a refund. A buyer who defaults on a firm agreement may instead lose the deposit and face additional claims.

If ownership of the deposit is disputed, RECO says a brokerage can release it under a mutual consent or release signed by the buyer and seller, or under a court order. A request from one party does not settle the dispute. Your lawyer can address the contractual entitlement and the documents needed for release.

Private sales and builder deposits

If there is no brokerage deposit holder, agree on the arrangement with your lawyer. A lawyer's trust account is different from a brokerage trust account. Do not assume RECO insurance applies to every person holding a deposit.

RECO specifically states that its consumer deposit coverage does not apply to deposits paid to a builder or transferred to a builder's lawyer in accordance with the purchase agreement. New-home deposit protections by Tarion apply separately.

HST on an Ontario Property Purchase

The HST clause addresses whether applicable sales tax is included in the price or payable on top. Get the tax treatment confirmed before signing, especially for new construction, assignments, commercial property or mixed-use buildings.

Resale homes

Sales of previously occupied residential homes are generally exempt from HST. Exceptions can arise from the property's use or the seller's activities. HST still applies to services such as legal work and real estate commissions even when the home itself is exempt.

New homes and first-time buyer rebates

New or substantially renovated homes sold by a builder are subject to Ontario's 13% HST. There are federal and Ontario first-time home buyer rebates available.

RebateWhat eligible buyers may receive
Federal first-time home buyers' GST/HST rebateRelief of the 5% federal tax component, up to $50,000. Full relief for qualifying homes priced up to $1 million; declining relief above $1 million; none at $1.5 million or more.
Ontario first-time home buyers' rebateRelief of the 8% provincial component, up to $80,000. Full relief up to $1 million, then reduced. At $1.5 million or more, the first-time buyer enhancement ends; the existing Ontario rebate of up to $24,000 may still apply.

These amounts do not mean every first-time buyer receives $130,000. The rebate depends on the tax paid, price, eligibility and interaction with existing rebates.

For a qualifying purchase from a builder, the federal program generally requires an agreement entered into on or after March 20, 2025, and before 2031, construction to begin before 2031, and substantial completion before 2036. Personal eligibility includes age, citizenship or permanent residence, occupancy and prior-home-ownership tests. The first-time buyer test considers the current calendar year and the previous four calendar years, including relevant ownership by a spouse or common-law partner.

Other Ontario relief

Ontario's temporary enhanced new housing rebate also covers eligible buyers who are not first-time buyers. For qualifying house-and-land purchases from a builder, the agreement generally must be signed from April 1, 2026, through March 31, 2027. Combined provincial relief can reach $80,000 through the $1.5 million price level, then declines below $1.85 million. Construction, completion, tax-payment and occupancy deadlines also apply.

An eligible buyer may also qualify for the Ontario new home affordability payment of up to $50,000, reduced by applicable federal housing rebates.

Check what the quoted price assumes

Ask whether the price includes HST, whether it is quoted net of rebates, which rebates are credited by the builder and who bears the cost if a claim is denied. Under the ordinary federal GST/HST new housing rebate, qualifying purchases of $350,000 or less may receive up to $6,300. The rebate is gradually reduced for purchases above $350,000 and is fully phased out at $450,000.

Your lawyer should confirm which rebates apply, how the builder has accounted for them in the purchase price, and the amount you will actually need at closing.

Guidance for Self-Represented Buyers and Sellers

You can buy or sell a home privately, but you are responsible for protecting your interests if you are not a client of a real estate brokerage. Retain your own lawyer early to help prepare or review the agreement, identify suitable conditions and arrange the deposit and closing.

If the other party has an agent, that agent represents their client's interests. They cannot give you advice as though you were their client. Before providing permitted assistance, they must explain RECO's information and disclosure form for self-represented parties.

Be careful about sharing your maximum budget, minimum acceptable price or reasons for moving; information you disclose may be passed to the agent's client. Ask who is authorized to receive formal notices, and use your lawyer to check delivery requirements. You can choose to engage your own brokerage, but doing so does not undo an agreement you have already signed.

Buyer and Seller Checklists

  • Property: The address, legal description and any condo parking or locker details match what you intend to buy.
  • Price: You understand the purchase price, tax wording and available funds for closing costs.
  • Deposit: The amount, holder, payment method and deadline are clear, and the funds are accessible.
  • Dates: Offer expiry, condition deadlines, title search, closing and possession dates work together.
  • Inclusions: Appliances and other agreed items are identified, including any promised condition or repairs.
  • Rentals: You have reviewed the contracts, costs and any transfer or buyout requirement.
  • Conditions: Each protection you need is included, with realistic deadlines and clear notice instructions.

Seller checklist before accepting

  • Exclusions: Identify fixtures you will remove and any agreed replacements.
  • Warranties: Understand every promise about condition, repairs, use, equipment or other matters. Do not sign statements you cannot support.
  • Offer expiry: Check whether acceptance can be properly completed and communicated before the deadline.

Use these checklists to review the completed contract with your lawyer or agent. They do not replace the wording of the agreement.

Frequently Asked Questions

Can a buyer back out after signing an Agreement of Purchase and Sale?

Signing and acceptance are different stages. Once the offer has been properly accepted, changing your mind is generally not enough to cancel. A valid condition, another contractual or legal right, or a negotiated release may allow the transaction to end. Leaving a firm agreement without a legal basis can put the deposit at risk and expose the buyer to additional damages. Get legal advice before refusing to close.

Is there a cooling-off period for an Ontario resale home?

There is generally no automatic cooling-off period for a typical Ontario resale home purchase. Do not assume the rules for a newly built condo purchased from a developer apply to a resale house or condo. Review the offer before committing, or negotiate an appropriate condition.

What happens if the seller rejects my offer?

A rejected offer does not create an accepted purchase agreement. The seller may reject it, let it expire or propose a counteroffer. A counteroffer needs acceptance; it is not an acceptance of the original terms. If you delivered a deposit with an offer that was not accepted, arrange its return with the deposit holder and confirm the paperwork required.

Can a seller reject an offer at the asking price?

Yes. Offering the asking price, or more, does not guarantee acceptance. The seller can consider the closing date, deposit, conditions and other terms as well as price.

What happens if my financing falls through?

If a valid financing condition is still in effect, the agreement may let you end the purchase if you comply with the clause and its deadlines. If there is no financing condition, or you already waived or fulfilled it, a later financing problem does not automatically cancel the purchase. Contact your lender and lawyer immediately; do not assume an extension will be granted.

Will I get my deposit back if a condition is not met?

You may be entitled to a refund if the agreement ends under a valid condition and its requirements have been followed. The wording, notice and circumstances matter. If the parties dispute entitlement, the brokerage does not decide who is right: release requires the appropriate signed consent or release, or a court order.

Can the purchase agreement be amended after acceptance?

Yes, if the parties agree to the change and properly document it. Common amendments change the closing date, price, repair obligations or condition deadlines. Identify the original agreement and the exact change, obtain the required signatures, and provide the amendment to the lawyers and lender where relevant. Asking for an amendment does not suspend an existing deadline. Have an extension completed before the deadline it is intended to change.
