What to do if you receive a lawyer’s letter in Ontario
A lawyer’s letter can feel intimidating, but it is not the same thing as a court order. It is a legal communication that deserves a thoughtful response.

Receiving a letter from a lawyer can be stressful. The letter may accuse you of doing something wrong, demand payment, threaten a lawsuit, ask you to stop certain conduct, or require a response by a deadline. Even if you believe the allegations are unfair, it is usually not a good idea to ignore the letter or fire back an emotional reply.
A lawyer’s letter is often written to put pressure on the recipient. It may be carefully worded to make the sender’s position sound stronger than it really is. It may also be designed to create a paper trail before court proceedings begin. That does not mean the other side is automatically right. It simply means the situation should be taken seriously.
A reply to a lawyer’s letter is a written response that addresses the issues raised in the letter. The goal is usually to protect your position, correct inaccurate statements, respond to demands, request more information, propose a resolution, or explain why you disagree. A good reply should be calm, organized, and strategic.
In Ontario, lawyer’s letters can arise in many kinds of disputes. These may include unpaid invoices, contract disputes, employment disputes, construction issues, defamation concerns, neighbour problems, shareholder disputes, business breakups, landlord and tenant issues, estate disputes, and civil claims. The right response depends on the type of dispute, the facts, the documents, and the risks involved.
One of the first things to check is whether the letter is actually a demand letter, a cease and desist letter, a settlement offer, a litigation warning, or something connected to an existing court case. If it is only a pre-lawsuit letter, you may have more flexibility in how to respond. If it is connected to a court proceeding, there may be formal deadlines that cannot be ignored.
This distinction matters. In Ontario Small Claims Court, for example, if you have actually been sued, responding is not the same as simply writing a letter back. The Ontario court system explains that a defendant who wants to respond to a Small Claims Court case must complete and serve a Defence, Form 9A. A casual email or letter to the opposing lawyer may not be enough to protect your position in court.
A lawyer’s letter may also mention a deadline. Some deadlines are practical deadlines set by the lawyer. Others may be connected to court rules, limitation periods, or contract requirements. In Ontario, the Limitations Act, sets important time limits for many civil claims, and missing a limitation period can create serious problems. If a letter mentions a deadline, it should not be dismissed without understanding what kind of deadline it is.
A strong reply should usually avoid unnecessary admissions. For example, if the letter says you breached a contract, caused damage, made a false statement, or owe money, you should be careful before agreeing with any part of that claim. Even a short sentence can sometimes be used later to argue that you admitted responsibility. A proper reply can respond to the issue without accidentally making the other side’s case easier.
At the same time, the reply should not be reckless or dishonest. If part of the other side’s letter is accurate, the response should be drafted carefully. Sometimes the best approach is to admit a basic background fact while denying liability. For example, you may admit that a contract existed, but deny that you breached it. Or you may admit that a payment is outstanding, but explain that the other side failed to complete the work.
Tone is very important. A lawyer’s letter may feel aggressive, but an angry response can make the dispute worse. Insults, threats, sarcasm, and long emotional explanations usually do not help. A good response should sound reasonable, firm, and professional. It should show that you understand the issue and are not ignoring the matter, without saying more than necessary.
A reply may also ask for more information. Sometimes a lawyer’s letter makes broad accusations without enough detail. In that situation, the response may ask for documents, dates, calculations, invoices, contracts, screenshots, photographs, or other information needed to understand the claim. This can be useful where the other side has not properly explained what they are demanding or why.
Some replies are written on a “without prejudice” basis. This phrase is often used in settlement discussions. Settlement privilege is a Canadian common law rule that generally protects genuine settlement communications from being used against a party later in litigation. However, the label should be used carefully. Not every response should automatically be marked without prejudice, especially if you may later want to rely on the letter to show what you said or requested.
A reply to a lawyer’s letter can also propose a settlement. This may include offering payment, requesting a payment plan, proposing a mutual release, asking for the return of property, suggesting mediation, or offering another practical solution. Settlement does not always mean admitting fault. Sometimes it simply means resolving the issue because the cost, stress, or risk of fighting is not worth it.
In other cases, the best response may be a firm denial. If the allegations are wrong, exaggerated, unsupported, or legally weak, a properly drafted reply can explain your position and make it clear that you will not simply accept the demand. This can sometimes cause the other side to reconsider before spending money on a lawsuit.
A reply can also help preserve your own claims. For example, the other side may accuse you of breaching an agreement, but you may have a claim against them as well. In that situation, the response may need to explain your position, identify their breaches, and reserve your rights. This can be especially important in business, employment, construction, and contract disputes.
It is also important to gather documents before responding. This may include contracts, invoices, text messages, emails, photos, payment records, purchase orders, screenshots, policies, employment agreements, or previous letters. A reply should be based on the actual evidence, not just memory or frustration.
You should also be careful about sending the letter to other people. Forwarding a lawyer’s letter to friends, posting about it online, or discussing the dispute publicly can create additional problems. If the matter involves defamation, confidentiality, employment issues, business records, or settlement discussions, public comments may make the situation worse.
