A customer stopped paying
The work is done, the invoice is overdue, and the replies have either stopped or keep promising next week.
We write and send demand letters for people and businesses who are owed money, a refund, or work that was paid for and never done. If the letter goes unanswered, we take the same file to court.




A demand letter goes to the person or business that owes you. It says what happened, what they owe, which documents prove it, and the date by which they have to pay or answer. It ends with the next step if they don't, which is usually a claim in court.
Ontario does not require one before most lawsuits. People send one because it is the cheapest step that can still get them paid, and because a judge reading it later sees that the other side had fair warning. A letter from a lawyer tells them you have taken advice and know which court comes next. It does not make them pay.
The work is done, the invoice is overdue, and the replies have either stopped or keep promising next week.
You lent money to a friend, a relative or a business partner. The e-transfers and messages show it, and the repayments have stalled.
You paid up front. The work never started, or stopped halfway, and the contractor will not give the money back.
A buyer, seller or supplier backed out and kept a payment that the agreement says comes back to you.
You generally have two years from the day you discovered the claim to start a court proceeding. A demand letter is not a proceeding. Sending one, waiting for an answer, or negotiating for months does not pause the clock.
On a debt for a fixed amount, the clock can restart if the person who owes you acknowledges the debt in a signed document, or pays part of it. Do not plan around that. If the two-year date is close, we start the claim at the same time as the letter, or instead of it.
Separately, no claim can be started more than 15 years after the events it is about, whatever you knew and when.

We read the agreement, the invoices and the messages, confirm exactly who owes you, and work out the amount.
We set out the facts, the amount, the documents it rests on, and a firm date to pay or respond.
We send it by email and by a method that proves delivery, so nobody can later say it never arrived.
If they answer, we negotiate and put any deal in writing. If they don't, we prepare the claim.
Gather what you have. A missing document is no reason to wait, least of all with a deadline running.

For most claims, no rule requires one. It is still usually worth sending. It gives the other side one last chance to pay without court, and it shows a judge later that you tried. A few kinds of claim carry their own notice rules and shorter deadlines, so we check for those first.
No. Under the Limitations Act, 2002, the two years keep running while you wait for an answer. Starting a claim stops it. So does a signed agreement with the other side to suspend the period. If the deadline is close, we start the claim instead of waiting on a reply.
You decide whether to sue. A claim of $50,000 or less, not counting interest and costs, belongs in Small Claims Court. A larger one goes to the Superior Court of Justice and starts with a statement of claim. We can draft and file either.
Long enough that a judge would call it fair, short enough to keep the matter moving. We usually set a date 10 to 14 days out, and sooner when a limitation date is close or money may be moved out of reach.
Note the response date and keep everything it refers to. Do not ignore it, and do not fire back an angry reply: what you write can be used later. Bring it to a consultation and we will tell you whether the claim holds up and how to answer it.
Work out the interest on the amount you are owed before you put a number in the letter, at the rates the Ministry of the Attorney General publishes each quarter.
