A free suite of Ontario Small Claims Court and debt-recovery tools — price a claim, the filing fees, the costs, and the interest; check your limitation deadline; build a demand letter; and find your courthouse. No sign-up, nothing leaves your browser, updated for 2026.

These tools do the arithmetic and the deadline-checking that trips up most self-represented litigants — from what a claim is really worth to whether you still have time to file. Each one is free, runs in your browser, and is dated and reviewed. They are a starting point, not legal advice — and when you want a lawyer in your corner, the free consultation is one click away.
Estimate the full value of your claim — principal, prejudgment interest, and recoverable court costs — for disputes up to $50,000.

Open the tool → CalculatorCompute the interest accruing on an unpaid judgment under s. 129 of the Courts of Justice Act, from the date of judgment to payment.
Open the tool → CalculatorEstimate the presumptive deadline to start a claim under the Limitations Act, 2002 — with special deadlines and notice traps flagged.
Open the tool → GeneratorBuild a complete, properly structured demand for payment in minutes — entirely in your browser, with nothing sent anywhere.

Open the tool →A debt-recovery matter runs in a predictable order, and there is a tool for each step. Start with the Limitation Period Calculator to confirm you are still in time to sue — a missed deadline ends the claim before it begins. Next, put the other side on notice: build a draft with the Demand Letter Generator, since a demand often gets you paid without court (just remember it does not pause the limitation clock). If you have to file, price the case with the Small Claims Court Calculator, the Filing Fee Calculator, and the Prejudgment Interest Calculator; confirm your courthouse in the court locations directory; and when you win, the Cost Award Calculator and Postjudgment Interest Calculator show what you can recover and what keeps accruing until you are paid.
Bring your situation to a free 30-minute consultation. Get a flat-fee quote and a real plan to recover what you're owed — before the limitation clock runs out.
These tools are information, not advice. Every figure they produce is an estimate based on what you enter, and limitation and costs law has exceptions a tool can't see. Using them does not create a lawyer–client relationship. If your matter is significant, have a lawyer confirm the numbers and your deadline before you rely on anything here.
Yes. Every calculator and tool here is completely free, with no account or sign-up required. They run in your browser and are built by Toronto lawyer Jonathan Kleiman as a public resource for Ontario litigants and small businesses.
No. They provide general legal information and estimates based on the figures and facts you enter. They are not legal advice, are not tailored to your situation, and using them does not create a lawyer–client relationship with Kleiman Law. For advice on your specific matter, book a free consultation.
Each tool is dated and reviewed. The rules and rates were verified against the official e-Laws consolidations and the Ministry of the Attorney General's published rates as of June 2026, including the $50,000 Small Claims Court limit in force October 1, 2025. Rules and rates change, so each tool carries its own "rules verified" stamp.
Yes. The tools compute everything in your own browser — nothing you enter is transmitted to or stored by Kleiman Law. Your information only leaves your device if you choose to submit a consultation request.
