- " It has no legal force on its own; the recipient can ignore it entirely with no immediate court consequence.
- A demand letter sets out the amount claimed, the basis for the claim, and a deadline to respond before further action is taken.
Both documents tell the other side you want money. Both can be written by a lawyer, printed on letterhead, and delivered by mail or courier. It's easy to see why people mix them up — but a demand letter and a Statement of Claim occupy completely different places in the legal process, and confusing them can lead to real strategic mistakes.
One is a request. The other is the start of a lawsuit. Here is what actually separates them.
The Core Distinction
A demand letter is a private communication — a warning shot that says "pay, or I will sue." It has no legal force on its own; the recipient can ignore it entirely with no immediate court consequence. A Statement of Claim is a formal court document filed with the Superior Court of Justice that actually commences litigation — once it is issued and served, the defendant is legally required to respond within a set time or risk having judgment entered against them.
In short: a demand letter is optional and informal in legal effect. A Statement of Claim is a formal legal proceeding with real deadlines and consequences attached the moment it is served.
Side-by-Side Comparison
| Demand Letter | Statement of Claim | |
|---|---|---|
| What it is | A written request for payment or action | A formal court document that starts a lawsuit |
| Where it's filed | Nowhere — sent directly to the other party | Filed with the Superior Court of Justice (or a Plaintiff's Claim in Small Claims Court) |
| Legal effect if ignored | None directly — no deadline is triggered for the recipient | The defendant has a set number of days to respond or risk default judgment |
| Cost to send | Generally a lawyer's drafting time only | Involves a court filing fee, plus service costs |
| Reversible? | Yes — can be withdrawn, revised, or simply dropped | More formal to discontinue once started; can affect costs |
| Public record? | No — stays private between the parties | Yes — court filings are generally part of the public record |
| Purpose | Prompt resolution before litigation | Formally assert and pursue your legal claim |
What a Demand Letter Actually Does
A demand letter sets out the amount claimed, the basis for the claim, and a deadline to respond before further action is taken. Its real power is psychological and practical, not legal: a firm, well-drafted letter — especially from a lawyer — signals that you are serious and prepared to escalate. It can also demonstrate to a court later that you gave the other side a fair chance to resolve the matter before suing, which can matter when costs are decided at the end of a case.
What it does not do is start any court process, create a filing on the public record, or trigger a response deadline enforceable by the court.
What a Statement of Claim Actually Does
Filing and serving a Statement of Claim is what formally commences a Superior Court civil action in Ontario. A related option, a Notice of Action, can be used to preserve a claim quickly but must be followed by an actual Statement of Claim within a defined window. Once served, the defendant has a set period to respond — the time frame depends on where they were served — and if they don't file a defence in time, the plaintiff may be able to obtain default judgment without ever going to trial.
This is a meaningfully bigger step than a demand letter: it involves an actual court filing fee, formal service requirements, and a document that becomes part of the record the court and (generally) the public can access.
Which One Should Come First?
For most disputes, the sequence runs demand letter, then Statement of Claim (or Plaintiff's Claim in Small Claims Court) if the letter doesn't resolve things. Jumping straight to a lawsuit is sometimes justified — for example, if a limitation deadline is close, or the other side has already made clear they won't pay regardless of a letter — but for most ordinary debt and contract disputes, a demand letter first is the standard, cost-effective approach.
When it makes sense to skip the demand letter
- Your limitation period is close to expiring and you can't afford the delay
- You already have clear evidence the other party has no intention of paying
- There is a real risk the debtor will move or hide assets if warned in advance
When a demand letter is worth sending first
- This is the first formal contact about the debt or dispute
- There is a reasonable chance of resolution without litigation
- You want to strengthen your position on costs if the matter does go to court
Frequently asked questions
Do I have to send a demand letter before I can sue in Ontario?
No — there is generally no legal requirement to send a demand letter before filing a Statement of Claim or Plaintiff's Claim, except in specific claim types with their own notice rules (defamation involving a newspaper or broadcast is a notable example with a short, separate notice requirement). For most ordinary claims, it's a strategic choice, not a legal prerequisite.
Can a demand letter be used against me later in court?
Yes. A demand letter and any response to it can become evidence — showing what was claimed, when, and how the other side reacted. This is one reason to be measured and accurate in a demand letter rather than making claims you can't support once the matter reaches court.
How long do I have to respond once I'm served with a Statement of Claim?
The response window depends on where you were served, and it is a firm deadline, not a suggestion — missing it can expose you to a default judgment without a trial. If you've been served, treat the deadline as urgent and get advice immediately rather than waiting to see if the other side follows up further.
Is a demand letter the same as a Notice of Action?
No. A Notice of Action is a formal court document that reserves a claim and requires a Statement of Claim to follow within a defined period — it is part of the court process. A demand letter is sent outside the court system entirely and creates no filing.
