Suing Over a Verbal Agreement in Ontario: A Practical Guide

A deal does not have to be written on paper to be real. If you are thinking about suing over a verbal agreement in Ontario, the first thing to know is that courts take these disputes seriously — a handshake deal or a promise made over the phone can be just as binding as a signed contract. The challenge is proving what was agreed and what went wrong.

This guide walks you through the key questions: whether your verbal contract holds up in law, what evidence you need, which court to use, and what to do before you file a claim.

Step 1: Is a Verbal Contract Valid in Ontario?

Yes — verbal contracts are generally enforceable in Ontario. The law does not require most agreements to be in writing. What it does require is that the basic building blocks of a contract exist:

• Offer: one party proposes specific terms.
• Acceptance: the other party agrees to those terms.
• Consideration: something of value is exchanged — money, work, a promise to do something, or a promise not to do something.
• Intention: both sides intended to be legally bound.

If those four elements exist, you likely have a contract — written or not.

Important Exceptions: When Writing Is Required

Not every agreement can stay verbal. Ontario's Statute of Frauds requires certain contracts to be in writing to be enforceable. The most common example in everyday life is an agreement to buy or sell land or real estate. If your dispute involves real property — a house, condo, or piece of land — and there is nothing in writing, you face a significant hurdle.

Other categories that typically require writing include guarantees of another person's debt and certain agreements that cannot be performed within one year. If your situation falls into one of these areas, get legal advice quickly, because the rules are technical and the exceptions matter.

For most other disputes — a contractor who did not finish a job, a friend who borrowed money and did not pay it back, a business deal that fell apart — a verbal agreement is enough to go to court with.

Step 2: What Evidence Can You Gather?

This is where verbal-contract cases are won or lost. The other side will often say the deal was different, or that no deal existed at all. Your job is to put together as complete a picture as possible of what was agreed and what happened next.

Text Messages and Emails

Even if the original agreement was spoken, most people follow up in writing at some point. Search for any texts, emails, or direct messages that mention the deal — amounts, timelines, deliverables, or anything that shows both sides knew what was expected. A message saying "Thanks for agreeing to fix the deck for $4,000 — I'll send a deposit tomorrow" can anchor a case that might otherwise rest on your word against theirs.

Witness Testimony

Was anyone else present when the deal was made? A friend, a family member, a colleague, or even a bystander? Witnesses who heard the conversation and can describe what was said are valuable. Courts weigh witness credibility, so the more neutral and specific the witness, the better.

Part Performance

Part performance means that one or both sides started acting on the agreement. If you completed work, delivered goods, or made a payment in line with the terms you claim were agreed, that conduct is evidence the agreement existed. Courts look at what people actually did — it is much harder for someone to claim there was no deal when you can show you performed your side of it and they accepted the benefit.

Payment Records

E-transfers, cheques, bank statements, or receipts showing money changed hands — in the amount and timing consistent with your version of the deal — are some of the strongest evidence available.

Course of Dealing

If you and the other party have done similar transactions before, that history is relevant. Past behaviour can show a pattern that supports your account of how this deal was structured.

Step 3: Which Court Do You Use?

Ontario gives you two main options depending on the dollar value of your claim.

Small Claims Court

Small Claims Court handles civil disputes up to $35,000 (as of writing — verify the current limit before filing, as it can change). The process is designed to be accessible without a lawyer, though legal help is still worthwhile. Filing fees are modest, and cases typically move faster than in Superior Court. If your verbal agreement involved a relatively modest amount of money, Small Claims Court is almost always the starting point.

Superior Court of Justice

For claims above the Small Claims limit, you file in the Superior Court of Justice. The process is more formal, discovery is involved, and legal representation is strongly advisable. Costs can be significant, but so can the amounts at stake.

Limitation Period

In Ontario, the basic limitation period for most civil claims — including breach of contract — is two years from the date you knew, or ought to have known, that a breach occurred and that you had a right to sue (as of writing — verify this applies to your specific situation). Missing the limitation period generally means losing your right to sue entirely, regardless of how strong your case is. Do not delay.

Step 4: How Is the Case Argued?

Once your claim is filed, the court will ask both sides to present their version of events. Your goal is to show, on a balance of probabilities — meaning it is more likely than not — that the agreement existed, that the other side breached it, and that you suffered a loss as a result.

Before You Sue: Demand Letter and Evidence Preservation

Two practical steps matter before any claim is filed:

1. Send a demand letter. A clear written demand — setting out what was agreed, what the other side did wrong, and what you want — gives the other party a chance to pay or negotiate. It also documents the dispute and shows the court you tried to resolve it. Many cases settle at this stage.

1. Preserve everything. Lock down all texts, emails, voicemails, photos, and records right now. Delete nothing. If witnesses are willing to put their recollection in writing, ask them to do so while it is fresh.
