Supply Agreement

A supply agreement is a contract under which a supplier agrees to sell goods to a business buyer over a period of time, usually through purchase orders issued under master terms on price, forecasts, minimum volumes, delivery, quality and termination. In Ontario, the Sale of Goods Act implies terms about title, description, quality and fitness for purpose into sales of goods, and business parties can exclude or vary them by express agreement. A cross-border sale between businesses in countries that have adopted the UN Convention on Contracts for the International Sale of Goods (CISG) is generally governed by that Convention unless the contract excludes it.

Key Takeaways

  • A supply agreement sets master terms once for a continuing flow of goods, and individual purchase orders then supply only quantity, price and delivery details.
  • Forecasts should state clearly which portion binds the buyer, and minimum commitments should be paired with exit rights for persistent supplier failure.
  • Ontario's Sale of Goods Act implies conditions and warranties about title, description, quality and fitness, and business parties can exclude or vary them by express agreement.
  • The CISG generally governs sales between businesses in different Contracting States, such as Canada, the United States and Mexico, unless the contract expressly excludes it.
  • Price adjustment, tariff pass-through, title and risk, and the exit plan on termination deserve specific clauses rather than boilerplate.

What Is a Supply Agreement?

A supply agreement governs a continuing flow of goods: raw materials, components, packaging, or private-label products made to the buyer's specifications. The parties agree the legal and commercial terms once; the buyer then issues purchase orders under them.

It differs from neighbouring agreements:

The master terms should also settle the battle of the forms. Purchase orders, acknowledgments and invoices often carry conflicting pre-printed terms, so the agreement should say that only quantity, price, delivery date and location are taken from those documents. Our guide to business agreements covers the other contracts a company needs.

Forecasts, Minimums and Capacity

The usual volume tools are:

  • Rolling forecasts. The buyer updates a forecast regularly, such as monthly for the next 6 to 12 months, and the agreement says which part binds (a firm window, such as the first four weeks) and which is only an estimate.
  • Minimum purchase commitments. The buyer commits to an annual volume or spend, sometimes with a shortfall payment if it buys less (take-or-pay).
  • Capacity and allocation. The supplier holds capacity or safety stock for the buyer and, in a shortage, allocates output by an agreed formula.
  • Exclusivity. The buyer may agree to buy all its requirements from the supplier, or the supplier may agree not to sell a custom product to the buyer's competitors.

Pair each commitment with an exit. A buyer that commits to minimums needs a way out if the supplier repeatedly misses delivery dates; a supplier that holds stock needs the buyer to pay for buyer-specific materials if forecasts collapse.

Sale of Goods Act: Conditions vs. Warranties

The Sale of Goods Act distinguishes two kinds of terms. Breach of a condition lets the buyer reject the goods and treat the contract as repudiated. A warranty is collateral to the main purpose of the contract, and its breach gives only a claim for damages. Under section 12, whether a term is a condition depends on the construction of the contract, a term can be a condition even if called a warranty, and once a buyer has accepted goods under a contract that is not severable, a breach of condition can generally be treated only as a breach of warranty.

Sections 13 to 16 imply these terms:

SectionImplied termType
13Seller has the right to sellCondition
13Quiet possession; no undisclosed charges or encumbrancesWarranty
14Goods match their descriptionCondition
15, para. 1Reasonably fit for a purpose the buyer made known, relying on the seller's skill or judgmentCondition
15, para. 2Merchantable quality, when bought by description from a seller who deals in such goodsCondition
16In a sale by sample, the bulk matches the sampleCondition

No fitness condition applies to a specified article bought under its patent or trade name, and, if the buyer has examined the goods, merchantable quality does not cover defects that the examination ought to have revealed.

Section 53 lets any implied right, duty or liability be negatived or varied by express agreement, course of dealing or binding usage. Supply agreements therefore commonly replace the implied terms with an express warranty, such as conformity to specifications for 12 months, and a defined remedy: repair, replacement, credit or refund. The exclusion should name implied conditions as well as warranties, and the Act itself. In consumer agreements, section 9 of the Consumer Protection Act, 2002 makes such exclusions void.

Cross-Border Supply and the CISG

The CISG applies to contracts for the sale of goods between parties whose places of business are in different Contracting States. It has been in force for Canada since May 1, 1992; the United States, Mexico and China are also Contracting States, but the United Kingdom is not. Under Article 1(1)(b), it can also apply when conflict-of-laws rules lead to the law of a Contracting State, such as Ontario, even if the other party's country is not one. In Ontario, the Convention has the force of law under the International Sale of Goods Act.

The Convention does not cover goods bought for personal, family or household use, or contracts in which the preponderant part of the supplier's obligations is labour or other services. Where it applies, several rules change:

  • There is no condition and warranty split. The buyer can avoid (terminate) the contract for a fundamental breach, one that substantially deprives it of what it was entitled to expect, or, for non-delivery, if the seller misses an additional delivery period the buyer has fixed.
  • The buyer must examine goods promptly and give notice of a lack of conformity within a reasonable time, and at the latest within two years of handover unless a contractual guarantee period says otherwise, or lose the right to rely on it.
  • A party is not liable in damages for a failure caused by an impediment beyond its control that it could not reasonably have taken into account, avoided or overcome.

Section 6 of Ontario's Act recognizes exclusion by expressly providing in the contract that the Convention does not apply. Because the Convention is part of Ontario law, a clause that simply chooses the laws of Ontario is not a reliable exclusion. Neither regime is always better; choose deliberately.

Price, Title, Delivery and Termination

Price adjustment. A common model fixes the first-year price, then adjusts it against a published index for a key input such as resin, steel or energy. Tariffs and other duties imposed or increased after signing need their own clause: who absorbs them, whether they pass through at documented cost, and whether the buyer can terminate above a threshold. If the contract adopts the ICC's Incoterms rules, they allocate the import burden: under DDP (delivered duty paid) the seller pays import duties, while under DAP (delivered at place) the buyer clears the goods and pays them.

Title and risk. Under section 21 of the Sale of Goods Act, risk passes with ownership unless otherwise agreed, so the agreement should state when each passes. A supplier that keeps title until paid holds a security interest under the Personal Property Security Act, which applies to conditional sales whatever they are called; without PPSA registration, it can lose out to other secured creditors or a trustee in bankruptcy.

Delivery remedies. Late delivery can carry a liquidated damages clause setting a pre-estimated amount per day or per order. Events outside both parties' control belong in a force majeure clause, drafted to work alongside the CISG exemption where the Convention applies.

Termination. Provide for termination for convenience on long notice, for breach after a cure period, and for insolvency or change of control. Then plan the exit: last-time buys, payment for buyer-specific finished goods and work in progress, return of buyer-owned tooling and moulds, and transition support to a new supplier.

Practical Example

Harjit Gill owns Peel Fresh Foods Inc., a Brampton maker of ready-to-eat meals. Peel Fresh signs a three-year agreement for printed pouches with Lakeshore Flexible Packaging LLC of Ohio, managed by Elena Rossi. Peel Fresh gives a 12-week rolling forecast, with the first four weeks binding, and commits to 2.4 million pouches a year at US$0.21 each, delivered duty paid to Brampton and adjusted quarterly against a resin index. New or increased duties pass through at documented cost, and Peel Fresh may terminate on 60 days' notice if a pass-through raises the landed price by more than 8%. The agreement chooses Ontario law, expressly excludes the CISG, and replaces the Sale of Goods Act's implied terms with a 12-month warranty of conformity to specifications, with Lakeshore liable for documented direct costs up to the value of 12 months' purchases.

In year two, a new duty raises the landed price by 6%. Lakeshore passes it through with customs documents; it is under the threshold, so Peel Fresh pays and starts qualifying a second supplier. Later, 400,000 pouches fail seal-strength testing. Peel Fresh gives written notice within the 10-day inspection window, and Lakeshore replaces the lot, worth US$84,000, and pays C$46,000 for spoiled meals and labour, well inside the cap. Nothing is litigated.

Frequently Asked Questions

What is the difference between a condition and a warranty under the Sale of Goods Act?+

A condition goes to the root of the sale, so a breach can entitle the buyer to refuse the goods and end the contract. A warranty is a secondary promise, and breaking it only supports a damages claim. Labels are not decisive: a court looks at the contract as a whole, and accepting the goods can limit the buyer to damages.

Can a business exclude the implied conditions in the Sale of Goods Act?+

Yes, between businesses. Section 53 allows implied terms to be negatived or varied by express agreement, by course of dealing or by binding trade usage. Clear wording that refers to both implied conditions and warranties works best, usually paired with an express warranty and remedy. Exclusions are void in consumer agreements under Ontario's consumer protection law.

Does the CISG apply to a contract between an Ontario company and a US supplier?+

Usually yes. Canada and the United States are both Contracting States, so the Convention applies to a sale of goods between businesses based in each country, unless the goods are for personal or household use or services predominate. The parties can opt out, but should say expressly that the Convention does not apply rather than rely on a choice of Ontario law.

Is a supply forecast binding on the buyer?+

Only to the extent the agreement says so. Many agreements make the near-term part of a rolling forecast a firm order and treat later months as non-binding estimates, sometimes with the buyer paying for materials bought to meet them. If the agreement is silent, expect a dispute, so define the firm window, permitted variances and the consequences of missing them.

What is the difference between a supply agreement and a distribution agreement?+

A supply agreement covers goods the buyer uses in its own business, such as components, ingredients or packaging. A distribution agreement covers goods the buyer resells to its own customers, so it adds territory, exclusivity, resale, marketing and brand terms. Some relationships combine both, and the document should reflect what the buyer actually does with the goods.
