A supplier missed a specification. A buyer's financing fell through by the closing date. A distributor didn't meet a delivery deadline written into the agreement. In every one of these situations, the first legal question isn't just "was the contract broken?" — it's "was the broken term a condition or a warranty?" That single classification decides whether you can walk away from the deal entirely or only sue for damages while staying bound to perform.
The Core Distinction
Ontario contract law generally sorts broken terms into two categories, with real consequences attached to each:
- A condition is a term so fundamental to the contract that breaching it goes to the root of the agreement. If a condition is breached, the innocent party generally has the option to terminate the contract (treat it as at an end) and also claim damages.
- A warranty is a less central term. If a warranty is breached, the innocent party is generally limited to claiming damages for the loss caused — they cannot use the breach as a reason to walk away from the rest of the deal.
The label a contract uses for a term ("this is a warranty that...") is a factor, but courts look at the real substance and importance of the term, not just the word chosen, when deciding how to classify a breach.
Why the Label Actually Changes the Outcome
| Condition Breached | Warranty Breached | |
|---|---|---|
| Can you terminate the contract? | Generally, yes | Generally, no |
| Can you claim damages? | Yes | Yes |
| Do you stay bound to perform your side? | Not if you validly terminate | Yes, generally |
| Practical effect | Deal can end; both sides walk away (subject to accrued rights) | Deal continues; compensation is the remedy |
Getting the classification wrong carries real risk on both sides. A party who wrongly declares a contract terminated over what was actually only a warranty breach may itself be found to have wrongfully repudiated the contract — turning the tables and exposing them to liability instead.
Where the "Sale of Goods" Framework Fits In
For contracts involving the sale of goods, Ontario's Sale of Goods Act provides a statutory framework distinguishing conditions and warranties for terms like the seller's title to the goods, their description, and their quality or fitness for purpose. This statutory structure is specific to goods transactions; for other kinds of contracts — services, real estate, shareholder agreements, and so on — the condition/warranty distinction is worked out under general contract law principles rather than that specific statute.
The Middle Ground: Terms That Don't Fit Neatly
Not every contract term sorts cleanly into "condition" or "warranty" at the outset. Courts also recognize an intermediate category — sometimes called an "innominate" or "intermediate" term — where the remedy depends on how serious the actual breach turned out to be in practice, rather than being fixed in advance by the term's label. If the breach substantially deprives the innocent party of what they bargained for, termination may still be available even though the term wasn't classified as a "condition" from the start; if the breach is minor, damages alone are the likely remedy.
This middle category is exactly why classifying a breach can require careful legal analysis rather than a quick read of the contract's wording.
Practical Steps When a Term Is Broken
- Identify exactly what was breached — pin down the specific clause and what it required.
- Assess how central that term was to the deal as a whole — was it a minor detail or something that goes to the heart of what you bargained for?
- Check how the contract itself frames the term, while remembering the label used isn't necessarily the final word.
- Get advice before declaring termination. Wrongly treating the contract as ended over a warranty-level breach can expose you to a counterclaim.
- Document the breach and its impact in case the classification is disputed later — this evidence matters whether you end up negotiating, mediating, or litigating.
Frequently asked questions
If a contract calls something a "condition," is that automatically decisive?
It's an important factor but not always the final word — courts look at the real substance and centrality of the term to the bargain, not just the label the contract uses.
Can I just cancel the contract if I think a condition was breached?
You can, but there's real risk in getting it wrong. If a court later decides the term was actually a warranty (or that the breach wasn't serious enough), your "termination" may be treated as a wrongful repudiation, potentially making you liable instead.
Does this distinction apply to all contracts, or just sales of goods?
The Sale of Goods Act's specific framework applies to goods transactions, but the broader condition/warranty/intermediate-term distinction is a general contract law concept that comes up across many types of agreements — services, leases, business sale contracts, and more.
What should I do if I'm not sure whether a breach lets me walk away?
Get legal advice before acting. The cost of a wrong call — either giving up a right to terminate you actually had, or wrongly terminating and exposing yourself to a counterclaim — is usually far higher than the cost of a proper legal assessment upfront.
