A demand letter is the cheapest way to get paid — often, the debtor pays the week it arrives. Answer a few questions and this tool builds a complete, properly structured demand for payment, live on the page. It runs entirely in your browser: nothing you type is sent anywhere unless you ask us to look at it.

A demand letter sets out who owes the money, what it is for, how much is owed, and a deadline to pay — and warns, in civil terms only, what happens if the deadline passes. This generator assembles that letter from your answers and shows it to you instantly. Send it as your own letter, or have Jonathan send the same demand on law-firm letterhead for a flat fee when a debtor needs to see that a lawyer is involved.
Five quick steps — who is owed, who owes it, what happened, your terms, and the tone. Everything stays in your browser.
A demand letter is the single cheapest step in debt recovery, and a surprising share of debts are paid the week one arrives. The ones that work share the same backbone: they are clear, accurate, civil, and specific. They name the debt, state the exact amount, give a firm but reasonable deadline, say precisely how to pay, and spell out — in civil terms only — what happens if the deadline passes. They read like the calm first move of someone who is fully prepared to go to court, because that is exactly what they are.
Just as important is what an effective demand letter leaves out. It does not insult the debtor, exaggerate the claim, or make threats it can't legally back up. It does not get marked "without prejudice." And it never threatens criminal charges, the police, or a regulatory complaint to squeeze out payment — more on each of those below.
This is the rule people most often get wrong. A demand letter to collect a private debt must stick to civil consequences: commencing a claim, getting judgment, and enforcing it. Threatening to have someone charged criminally, reported for fraud, or reported to a regulator in order to pressure them into paying can amount to extortion under section 346 of the Criminal Code — and for a lawyer it breaches the Law Society of Ontario's Rules of Professional Conduct. That holds even when a cheque bounced. This generator only ever produces civil-consequences language, on purpose.
"Without prejudice" is a privilege that keeps genuine settlement discussions out of evidence. A demand for payment is the opposite — it's something you generally want a judge to see later, to show you asked for payment, set a fair deadline, and behaved reasonably (which matters when costs are decided). Stamping a plain demand "without prejudice" can stop you from relying on it. So this letter is sent on an open basis. Save "without prejudice" for a separate letter that actually offers a compromise.
A demand letter does not pause the limitation clock. In Ontario you generally have two years from the day you discovered the claim to start a court proceeding (Limitations Act, 2002). Sending a demand — and waiting weeks for a reply — does not stop, extend, or reset that clock. People lose otherwise-good claims this way every year. Before you sit back and wait, run your dates through the Limitation Period Calculator, and if the deadline is anywhere close, get advice the same day.
If the deadline comes and goes with no payment and no agreement, your main route is to commence a civil claim. Amounts up to $50,000 go to the Small Claims Court; larger claims go to the Superior Court of Justice. You can price the whole picture first: the Small Claims Court Calculator rolls principal, interest, and recoverable costs into one claim value; the Filing Fee Calculator prices what you'll pay to file; and the Cost Award Calculator shows how much of your legal bill a win can recover. Just confirm you're still inside the limitation period before you file — a missed deadline can mean the demand was your last available move.
When a debtor sits on your own letter, a demand on law-firm letterhead — signed by a lawyer — often gets a different answer. Flat fee, quoted up front. Free 30-minute consultation.

No. A demand letter isn't a legal precondition to filing in the Small Claims Court or the Superior Court of Justice. But it's almost always worth sending: it often gets you paid without litigation, and it creates a written record that you asked for payment and gave a reasonable deadline — which helps on costs if the matter ends up in court. Many debts are paid the week a proper demand arrives.
No — and this is the most dangerous misconception about demand letters. Under the Limitations Act, 2002, you generally have two years from the day you discovered the claim to start a proceeding. Sending a demand does not pause, extend, reset, or "toll" that clock — it keeps running while you wait for a reply. Only specific events (a signed written acknowledgment of the debt by the debtor, a part payment, or a formal tolling agreement) affect the period, and a demand from you isn't one of them. Check your dates with the Limitation Period Calculator and speak to a lawyer if the deadline is near.
Usually not. "Without prejudice" is a privilege that keeps genuine settlement offers out of evidence. A demand for payment is something you generally want to be able to put in front of a judge — to show you asked for payment, gave a deadline, and were reasonable. Stamping a plain demand "without prejudice" can stop you from relying on it, including on costs. Send the demand on an open basis, and save "without prejudice" for a separate letter that actually makes a settlement concession. This generator deliberately does not mark the letter "without prejudice."
No. A demand to collect a civil debt must stick to civil consequences — commencing a claim, getting judgment, and enforcing it. Threatening criminal prosecution, a fraud charge, or a regulatory complaint to pressure payment can amount to extortion under section 346 of the Criminal Code, and for lawyers it breaches the Law Society of Ontario's Rules of Professional Conduct. That's true even when a cheque bounced (NSF). This generator only ever produces civil-consequences language for exactly this reason.
A reasonable deadline is usually 10 to 21 days from the date of the letter. Ten days suits a clear, undisputed debt where time matters; fourteen is the common middle ground; twenty-one is courteous where the amount is large or the relationship is ongoing. The deadline doesn't change your legal rights — you can sue with or without giving one — but an obviously reasonable deadline looks better to a court and gives the debtor a fair chance to pay.
If the deadline passes with no payment and no agreement, your main option is to commence a civil claim. Claims up to $50,000 are heard in the Small Claims Court; larger claims go to the Superior Court of Justice. If you win, you can ask for judgment for the debt plus interest and recoverable costs, then enforce it (garnishment, a writ). Before filing, confirm you're still inside the two-year limitation period.
Often, yes. A debtor who ignores an individual will frequently pay when the same demand arrives on law-firm letterhead, signed by a lawyer — it signals that litigation is genuinely on the table. A lawyer can also make sure the letter is accurate and doesn't create problems (like inadvertently waiving rights or overstating the claim). Jonathan sends demand letters on Kleiman Law letterhead for a flat fee quoted up front. The free letter here is a solid starting point; the lawyer version is the next step when the first one is ignored.
Yes. The letter is built entirely inside your own browser — nothing you type is sent to Kleiman Law or anyone else, the page stores nothing, and the letter you generate is never attached to or sent with anything. Your information only leaves your browser if you choose to fill in and submit the separate consultation form below. Using this tool is free and does not create a lawyer–client relationship.
You've drafted the demand. If it's ignored — or you'd rather it land harder the first time — Jonathan Kleiman sends the same demand on Kleiman Law letterhead, under his signature, for a flat fee quoted up front. Debtors respond differently when a lawyer is on the file.
Describe your situation in general terms and Jonathan will contact you — usually the same day.
This page provides general legal information about demand letters and debt recovery in Ontario, and a tool that assembles a draft letter from the facts you enter. It is not legal advice and is not tailored to your circumstances. The draft it produces is your own letter — it goes out under your name, is not on Kleiman Law letterhead, and does not imply that a lawyer is acting for you. Using this tool does not create a lawyer–client relationship with Kleiman Law. The legal points referenced here — including the two-year limitation period under the Limitations Act, 2002, the $50,000 Small Claims Court monetary limit (O. Reg. 626/00, as amended by O. Reg. 42/25, in force October 1, 2025), prejudgment interest under s. 128 of the Courts of Justice Act, and the limits on threatening criminal proceedings to collect a civil debt — were verified against the official e-Laws consolidations on ; the law changes, and this page may not reflect changes after that date. Critically, sending a demand letter does not pause, extend, or reset any limitation period. No warranty is given as to accuracy or completeness, and Kleiman Law accepts no liability for reliance on this tool. Consult a lawyer about your specific situation before sending a demand or deciding whether to sue.
