The Agreement of Purchase and Sale is the legal foundation of every residential real estate transaction in Ontario. What it says, what it omits, and how its conditions are structured determine the legal rights and obligations of both parties from the moment it is signed.
Ontario’s residential real estate market moves quickly. Offers are prepared and submitted within hours of a property coming to market. Multiple offer situations compress the timeline further, creating an environment in which buyers sign complex legal documents under time pressure and sellers accept or reject offers based on a document review that is often cursory.
The Agreement of Purchase and Sale governs what is being sold, on what terms, and at what price. It determines what happens if financing is not arranged, if a home inspection reveals a material defect, if the seller fails to close, or if a dispute arises about what was included in the sale. Once both parties have signed and conditions have been waived, the agreement is binding and its terms are not easily changed.
Understanding what is negotiable in a residential APS, and why specific provisions matter, is valuable for any buyer or seller entering a transaction. This article covers the key elements of a standard residential agreement, identifies where the most significant risks and opportunities lie, and explains why the moment before signing is the most important point at which legal advice adds value.

The Structure of the Standard Residential APS
The standard residential Agreement of Purchase and Sale used in Ontario is based on forms published by the Ontario Real Estate Association. The form has evolved over decades and is widely used by real estate agents across the province. It provides a consistent transactional structure that both buyers and sellers and their advisors recognize and understand.
The standard form addresses the fundamental elements of the transaction: the identities of the parties, the legal description of the property, the purchase price and deposit, the chattels and fixtures included in the sale, the closing date, and a set of conditions that must be satisfied before the agreement becomes firm. It also contains provisions governing the seller’s representations about the property, the allocation of risk during the period between signing and closing, and the remedies available to each party in the event of a default.
The standard form is a starting point, not a complete agreement. The provisions that reflect the specific facts of a particular transaction are inserted through schedules and amendments. A buyer who relies on the printed terms of the standard form without considering what additional provisions are required, or what modifications to the standard language the specific transaction warrants, is relying on a document that was designed for the average transaction rather than their own.
Conditions: The Buyer’s Primary Protection
Conditions are the most important negotiable element of a residential APS for most buyers. A condition gives one party the right to rescind the agreement if a specified circumstance does not materialize, without being in breach of contract. Properly drafted, conditions provide meaningful protection. Improperly drafted, they may not work when they are needed.
Financing Condition
A financing condition gives the buyer the right to rescind the agreement if they are unable to arrange satisfactory mortgage financing within the condition period. In a standard transaction, the financing condition period is typically five to ten business days, during which the buyer seeks mortgage approval.
The scope of the financing condition matters considerably. A condition drafted as “subject to the buyer arranging satisfactory financing” is broader than one that specifies particular terms, such as a minimum loan amount, a maximum interest rate, or a specific amortization period. Buyers whose financing requirements are specific should ensure the condition language reflects those requirements precisely, so that the condition can be exercised if the available financing falls short of what the buyer actually needs.
In competitive markets, buyers sometimes waive financing conditions to strengthen their offer. This is a significant decision that should not be made without understanding its legal implications. A buyer who waives a financing condition and subsequently cannot secure a mortgage is in breach of the agreement if they fail to close. The consequences can include loss of deposit and a claim by the seller for additional damages. A buyer who proceeds without a financing condition should have a high degree of certainty about their financing position before doing so.
Home Inspection Condition
A home inspection condition gives the buyer the right to have the property inspected by a qualified home inspector and to rescind the agreement if the inspection reveals defects that are unsatisfactory to the buyer. The condition is typically exercised within a period of five to seven business days from acceptance.
The drafting of the home inspection condition determines what the buyer can actually do with the inspection findings. A condition that entitles the buyer to rescind only if a defect is discovered that the buyer could not have known about before the offer is narrower than one that allows rescission at the buyer’s discretion based on the inspection results. Buyers in competitive offer situations sometimes use a pre-offer inspection to demonstrate commitment while preserving the ability to review results, though this approach carries its own complications.
A home inspection does not guarantee that all defects will be discovered. Inspectors assess accessible and visible components of the property at the time of inspection; they cannot identify concealed defects, latent conditions, or problems that become apparent only over time. The inspection condition is a meaningful but imperfect protection, and buyers should understand what it covers and what it does not.
Status Certificate Condition (Condominiums)
For condominium purchases, a status certificate condition is essential. Under the Condominium Act, 1998, a buyer has ten days from receipt of the status certificate to review it and, if they choose, rescind the agreement unconditionally. The right to rescind does not require justification and the deposit must be returned in full.
The status certificate discloses the financial and legal health of the condominium corporation, including the reserve fund balance, any pending litigation, outstanding special assessments, and the corporation’s Declaration, By-Laws, and Rules. Review by a lawyer is not technically required by the Act, but the document package is voluminous and the issues it can reveal are legally and financially significant. A buyer who reviews the status certificate without legal counsel is relying on their own understanding of a complex corporate document to make a decision with material financial consequences.
The ten-day window is a statutory protection that expires whether or not the review has been completed. Buyers who receive a status certificate should instruct their lawyer immediately. For a detailed discussion of what a status certificate contains and what a lawyer reviews within it, see our dedicated article on the topic.
Condition Period Length and Waiver
The length of each condition period is negotiable. In a standard market, condition periods of five to ten business days are common. In competitive offer situations, sellers may press for shorter periods or, in some cases, clean offers with no conditions at all.
A condition period that is too short to complete the required steps is a condition that may be difficult to exercise properly. A buyer who cannot arrange a home inspection within a two-day condition period because inspectors are unavailable, or who cannot complete a status certificate review within three days because the certificate has not yet been received, may find themselves in a position where they must either waive the condition without the intended information or rescind and lose the property.
The decision about condition periods and whether to include conditions at all should be made with a clear understanding of the legal consequences of waiver versus rescission, and with realistic knowledge of what can actually be accomplished within the time available.
Deposit: Amount, Timing, and Consequences of Default
The deposit is the sum paid by the buyer at or shortly after acceptance of the offer, held in trust by the listing brokerage until closing. It forms part of the purchase price and is credited to the buyer on closing. Its primary function, from the seller’s perspective, is as a form of security for the buyer’s performance.
The amount of the deposit is negotiable. In Ontario residential transactions, deposits typically range from one to five percent of the purchase price, though higher deposits are not unusual in competitive markets. A seller receiving multiple offers may weight a higher deposit as a signal of the buyer’s commitment and financial capacity.
If the buyer fails to close after the agreement has gone firm, the seller is generally entitled to retain the deposit as liquidated damages. Whether the seller can also claim additional losses beyond the deposit depends on the terms of the agreement and the actual damages suffered. In a rising market, the seller’s actual loss from a buyer default may exceed the deposit amount if the property must be relisted at a lower price. In a declining market, the deposit may exceed the seller’s actual loss. Understanding this dynamic is relevant to both parties when negotiating the deposit amount.

Chattels and Fixtures: What Is Included in the Sale
The distinction between chattels and fixtures is a recurring source of post-closing disputes. A fixture is an item that has been permanently attached to the property and passes with the real estate on closing. A chattel is personal property that does not pass with the real estate unless specifically included in the agreement.
The boundary between the two categories is not always obvious. Kitchen appliances, light fixtures, window coverings, built-in shelving, and garage door openers are among the items that buyers and sellers most commonly disagree about. The standard APS form contains spaces for the parties to specify included chattels and excluded fixtures, but these sections are not always completed with the precision the situation requires.
Buyers should identify every item they expect to be included in the sale and list it explicitly in the agreement. Sellers should identify any fixtures they intend to remove before closing and exclude them explicitly. A light fixture the seller intends to take because it was a wedding gift, a built-in refrigerator the buyer assumes is included, and a chandelier that is clearly attached but may or may not have been intended as an inclusion are all examples of items that should be addressed in writing rather than assumed.
Post-closing disputes about chattels and fixtures are difficult and expensive to resolve. Prevention through precise drafting costs nothing.
Closing Date
The closing date is negotiated between the parties and must be acceptable to both. For buyers, the closing date affects financing arrangements, bridge financing if they are also selling, moving logistics, and lease obligations for those transitioning from a rental. For sellers, the closing date must align with their own purchase, if applicable, and with any obligations to current tenants or occupants.
A closing date that is too soon may not allow adequate time for the buyer to complete due diligence, satisfy financing conditions, arrange title insurance, or coordinate the transfer of funds. A closing date that is far in the future creates a longer period during which circumstances can change, financing conditions can expire, and the property can deteriorate.
The agreement should address what happens if the closing date cannot be met. Provisions for extending the closing date by mutual consent, the consequences of a party’s failure to close on the agreed date, and the allocation of carrying costs during any extension period should be considered, particularly in transactions where timing is tight or where one closing is dependent on another.
Representations About the Property’s Condition
Ontario follows a modified form of the common law principle of caveat emptor, or buyer beware, in residential real estate transactions. A seller is not generally required to volunteer information about defects in the property, but is prohibited from actively concealing or misrepresenting material facts. The distinction between non-disclosure and active misrepresentation has been the subject of considerable litigation in Ontario courts.
The standard APS form contains a seller’s representation that the property will be in the same condition at closing as at the time of acceptance, and that the seller is not aware of any latent defects affecting the property other than those disclosed. These representations are significant but limited. A seller who is unaware of a latent defect makes no representation about it; a buyer who discovers a defect the seller did not know about generally has no claim under the agreement.
Buyers who are concerned about specific aspects of the property’s condition should use the condition period and the home inspection to investigate those concerns, rather than relying on implied representations. Where a seller has made specific representations about the property, whether verbally through the agent or in writing, those representations should be reflected in the agreement itself. Oral representations that are not incorporated into the written agreement are difficult to enforce.
The Case for Legal Review Before Signing
The most common framing of a real estate lawyer’s role is as a closing agent: the professional who handles title, registers documents, and manages the exchange of funds on closing day. That role is important. It is not, however, where legal advice adds the most value.
The greatest value of legal counsel in a residential real estate transaction is at the moment before the agreement is signed. The agreement is a binding contract. Once executed and conditions waived, its terms are fixed and the parties’ obligations are determined. A buyer who does not understand the financing condition they have agreed to, the scope of the home inspection condition they are relying on, or the chattels that will and will not be present at closing is a buyer who will discover those gaps only when something has already gone wrong.
Legal review before signing does not require a lengthy process. For a straightforward residential transaction, a lawyer can review the draft agreement and provide meaningful commentary within a short timeframe. The cost is modest. The benefit is a clear understanding of the terms being agreed to, the protections being relied on, and any provisions that warrant modification before the other party signs.
The window for making those modifications is open before signing. After signing, it requires the seller’s cooperation to reopen.
