Sale of Goods Agreements in Ontario

Ontario’s Sale of Goods Act applies to contracts for the sale of goods — tangible, movable property, as opposed to real estate, services, or intangible rights. This covers an enormous range of everyday and commercial transactions: buying equipment for a business, ordering inventory from a supplier, purchasing a vehicle, or selling finished products to a customer.

What makes this Act distinctive is that it doesn’t just sit in the background as general contract law — it actively reads a set of default terms into most sale-of-goods contracts, whether or not the parties ever discussed them. A short purchase order or a simple handshake deal for goods can carry legal obligations that neither side wrote down, simply because the Act fills in the gaps.

These default, or “implied,” terms matter most when a dispute arises — when goods turn out to be defective, don’t match what was described, or fail to work for their intended purpose. Understanding what the Act implies into a contract helps explain why a seller can sometimes be on the hook for a problem even without an explicit written promise covering it.

The Act applies alongside, not instead of, general contract law principles — ordinary rules about offer, acceptance, and consideration still determine whether a sale contract exists in the first place. The Sale of Goods Act layers on top of that foundation a set of goods-specific default terms that fill in gaps the parties’ own agreement may have left open, whether that silence was deliberate or simply an oversight.

The Sale of Goods Act implies several specific terms into most contracts for the sale of goods, unless they’re validly excluded.

Merchantable quality generally requires that goods sold by a seller who deals in that kind of goods be fit for the ordinary purposes they’re normally used for, and free of defects that would make them unsuitable for that general use.

Fitness for a particular purpose applies where a buyer tells the seller about a specific purpose for the goods and relies on the seller’s skill or judgment to supply something suitable for that purpose. If those conditions are met, the goods need to actually work for the stated purpose, not merely function in a generic sense.

Correspondence with description or sample requires that goods sold by description, or by reference to a sample, actually match what was described or shown. A buyer who orders “grade A” materials, or who approves a sample before a bulk order, is generally entitled to receive goods matching that description or sample.

Quantity is also addressed by the Act’s default rules, which generally give a buyer some flexibility where a seller delivers more or less than what was ordered — allowing rejection of the whole delivery, acceptance of only the quantity ordered, or in some cases acceptance of the full amount delivered, depending on how significant the discrepancy is and what the parties’ contract itself provides for.

In many commercial, business-to-business contracts, the implied terms described above can be excluded or modified by clear language in the agreement — commonly through an “as is,” “no warranties,” or similarly worded disclaimer clause. Courts generally require this kind of exclusion to be clearly worded and properly brought to the other party’s attention before it will be enforced.

Consumer transactions are treated more cautiously. Separate consumer protection legislation in Ontario places limits on how far a seller can go in excluding these kinds of protections when dealing with an individual consumer rather than another business, recognizing the typically unequal bargaining positions involved.

Even where an exclusion clause is generally valid, courts have sometimes declined to enforce one where a seller’s conduct was fundamentally inconsistent with the contract, or where the clause itself was buried, unclear, or unconscionable. A valid, well-drafted exclusion still needs to be genuinely clear and fairly presented to hold up if challenged.

Two related but distinct questions often come up in sale-of-goods disputes: when does legal ownership (title) of the goods transfer from seller to buyer, and who bears the risk if the goods are lost or damaged before delivery is complete.

Under the Act’s default rules, these two questions can actually be answered differently — title might pass at one point (for example, when the contract is formed, or when goods are identified and set aside for the buyer) while risk of loss passes at a different point (often tied to delivery). A well-drafted contract typically addresses both explicitly rather than relying on these default rules, since the default outcome isn’t always obvious or intuitive to either party.

Shipping and delivery terms are a common way contracts make this explicit — specifying, for instance, that risk transfers once goods leave the seller’s premises, once a carrier takes possession, or once the buyer actually receives the goods. Clarifying this upfront avoids a dispute over who bears the cost if goods are damaged or lost in transit.

When goods turn out to be defective, don’t match their description, or aren’t fit for their stated purpose, a buyer’s available remedies generally depend on the nature and severity of the problem, and on whether the buyer has already accepted the goods.

Where the defect is significant and the goods haven’t yet been accepted, a buyer may be able to reject the goods outright and refuse to pay, treating the breach as going to the heart of the contract. Where the goods have already been accepted, or the defect is less severe, the more typical remedy is a claim for damages — compensation for the difference in value, repair costs, or other resulting loss — rather than outright rejection.

Many commercial contracts also specify their own remedy process directly — such as a right to repair or replacement within a defined window, or a specific procedure for raising a quality complaint — which can operate alongside, or sometimes in place of, the Act’s default remedies, depending on how the contract is worded.

A sale-of-goods contract is legally distinct from a services contract, which covers work performed rather than tangible property transferred. The implied terms discussed in this article — merchantable quality, fitness for purpose, correspondence with description — are specific to the Sale of Goods Act and don’t automatically apply to a contract for services in the same way.

Many real-world transactions blend the two — a supplier that sells equipment and also installs or maintains it, for example. In these mixed cases, courts generally look at the substance of the transaction to determine which category predominates, which in turn affects which default rules and implied terms are most relevant if something goes wrong.

This distinction can also affect how a dispute is framed procedurally — a claim centred on defective goods often focuses on the condition of what was delivered at a specific point in time, while a claim about services more often focuses on the standard of care and skill applied throughout the work. Identifying which framework actually governs a given transaction is often the first practical step in understanding what remedies might realistically be available.
