Suing for Breach of a Verbal Agreement in Ontario

A surprising number of everyday disputes trace back to an agreement that was never written down — a price agreed over the phone, a deal struck with a handshake, terms worked out in a conversation and never followed up in an email. People are often unsure whether that kind of agreement even counts as a real contract. In Ontario, it usually does — but suing over one takes a different approach than suing over a signed agreement.

Are verbal contracts actually enforceable?

As a general rule, Ontario law does not require a contract to be in writing to be valid and enforceable. If two people reach a clear agreement — an offer, an acceptance, and something of value exchanged between them — that agreement can generally be enforced whether it was written down or simply spoken. This applies to plenty of common Small Claims Court disputes: an agreed price for a repair job, a verbal understanding about repaying a personal loan, or a spoken agreement to provide a service by a certain date. See unpaid invoices and loans for how this plays out in some of the most common scenarios.

Why verbal agreements are harder to prove

The legal enforceability of a verbal contract has never really been the hard part — proving what was actually agreed to is. With a written contract, the terms are largely fixed on the page. With a verbal agreement, the court has to reconstruct what was said, often from two people who now remember the conversation differently, sometimes months or years after the fact. This doesn't make a verbal agreement claim hopeless, but it does shift the emphasis from "was there a contract" to "can I show, through other evidence, what its terms actually were."

Evidence that can support your case

Because the conversation itself usually can't be replayed, the strongest verbal-agreement cases tend to lean on evidence around the conversation. That can include text messages or emails that reference the deal even if they don't spell out every term ("confirming we said $2,400 for the fence, half up front" is powerful even as a casual text); witness testimony from someone who was present or who the parties later described the agreement to; partial payment or performance consistent with the alleged terms, such as a deposit paid in the amount discussed or work actually started on the agreed schedule; and evidence of standard industry or market rates, which can help show that the price or terms you're describing are plausible rather than invented after the fact. See proving your case and using witnesses for more on building this kind of record.

Small Claims Court's relaxed evidence rules

One thing that genuinely works in favour of verbal-agreement claims is that Small Claims Court operates under more relaxed evidence rules than the higher courts. Under the Courts of Justice Act, Small Claims Court is permitted to admit a broader range of evidence, including some hearsay — an out-of-court statement offered to prove the truth of what it asserts — that would often be excluded in a formal Superior Court trial. This doesn't mean anything and everything gets accepted automatically, or that hearsay carries as much weight as direct testimony; the judge still decides what's admitted and how much weight to give it. But it does mean a verbal-agreement case isn't fighting an uphill battle against strict formal evidence rules the way it might in a higher court. See evidence and witnesses for how this works in practice at a hearing.

The Statute of Frauds: what must be in writing

There are exceptions to the general rule that verbal contracts are enforceable. Ontario, like other common law jurisdictions, has rules tracing back to a long-standing piece of legislation known as the Statute of Frauds, which requires certain categories of agreements to be in writing and signed in order to be enforceable at all. Contracts involving an interest in land — such as an agreement to sell real estate — and certain types of guarantees (where someone promises to answer for another person's debt) are commonly cited examples that generally need to be in writing. This is a narrower list than many people assume, and it doesn't cover most everyday service, sale of goods, or repayment agreements — but if your dispute touches on real estate or a guarantee, it's worth confirming with a professional whether a written agreement was actually required before relying on a verbal one.

Practical tips if you only have a verbal agreement

If you're in a dispute over a verbal agreement, start by writing down, as soon as possible, everything you remember about it — the date, who was present, and the exact terms as best you recall them — since your own memory will only fade further with time. Gather every message, email, receipt, or record that touches on the deal, even indirectly. Identify anyone who witnessed the agreement or who you told about it afterward, and consider whether a demand letter referencing the specific terms, sent before you file, could prompt the other side to confirm or dispute those terms in writing. See writing an effective demand letter for how to approach that step, and how to write a statement of claim for how to describe a verbal agreement clearly once you're ready to file.
