If someone owes you money, has breached a contract, or has caused you harm, you might be wondering what your first step should be. In many situations in Ontario, that first step is sending a demand letter. It sounds formal, but the idea behind it is actually quite straightforward. This article explains what a demand letter is, what it usually includes, and why it can be an important tool before you consider taking legal action.
What Is a Demand Letter?
A demand letter is a written communication, usually prepared by a lawyer, that formally tells another person or business that you have a legal claim against them and that you expect them to do something about it. That something might be paying money they owe you, returning property, stopping a particular behaviour, or fulfilling an obligation under a contract.
The letter typically sets out what happened, what you are claiming, and what you want the other side to do in order to resolve the matter. It usually gives a deadline for a response, and it often makes clear that legal proceedings may follow if the issue is not addressed.
A demand letter is not a lawsuit. It does not start court proceedings on its own. Think of it as a serious, documented way of saying: here is the problem, here is what I need from you, and here is how long you have to respond before I take further action.
What Does a Demand Letter Usually Include?
While demand letters can vary depending on the situation, most of them will cover the following:
A clear explanation of the facts. The letter sets out what happened, when it happened, and who was involved. This helps the other party understand exactly what you are claiming and why.
The legal basis for your claim. The letter may refer to a contract, a duty of care, or another legal obligation that the other side has not met. This shows that your claim has a foundation and is not simply a complaint.
What you are asking for. Whether it is a specific dollar amount, the return of property, or some other form of action, the letter spells out exactly what you need.
A deadline. Most demand letters give the other side a set period of time to respond or comply, often anywhere from 7 to 30 days depending on the circumstances.
A statement about next steps. If the other side does not respond or refuses to cooperate, the letter typically states that you may pursue legal action, which could include going to Small Claims Court or the Superior Court of Justice in Ontario.
Why Does a Demand Letter Matter?
You might be wondering whether a demand letter is worth the effort. In many cases, yes, it can be. Here are some of the reasons why:
It May Help You Resolve the Dispute Without Going to Court
Sometimes people pay up, or agree to a resolution, once they receive a formal letter. The simple act of putting your claim in writing, in a professional and documented way, can make the other side take the situation more seriously. Litigation is expensive and time-consuming for everyone involved, and a demand letter gives both sides the opportunity to resolve things before things escalate.
It Documents Your Claim and Shows You Acted in Good Faith
If you do end up going to court, having a demand letter on record can be helpful. It shows that you made a reasonable effort to resolve the matter before pursuing legal proceedings. Courts in Ontario generally look favourably on parties who tried to work things out before filing a claim.
It Can Help Preserve Your Legal Rights
In Ontario, there are time limits on how long you have to bring a legal claim. These are known as limitation periods. Under the Limitations Act, 2002, the general rule is that you have two years from when you discovered, or ought to have discovered, your claim to start legal proceedings. Sending a demand letter will not stop that clock from ticking, but it does create a clear record of when the dispute began and when you took action. Speaking with a lawyer early can help you understand how limitation periods may apply to your specific situation.
It Sets Out Your Position Clearly
Sometimes disputes arise because of misunderstandings. A well-written demand letter lays out the facts and your position clearly, which can help move things toward a resolution more quickly. It also puts the other side on notice that you are serious about your claim.
When Should You Consider Sending a Demand Letter?
There is no single rule about when to send a demand letter, and not every situation calls for one. That said, they are commonly used in disputes involving:
Unpaid invoices or debts between individuals or businesses
Breach of a written or verbal contract
Property damage
Landlord and tenant disputes in some cases
Disputes between neighbours
Personal injury matters in some circumstances
If you are unsure whether a demand letter makes sense in your situation, it is worth speaking with a lawyer. A lawyer can help you assess the strength of your claim, draft the letter in the right tone, and advise you on your options going forward.
What Happens After the Letter Is Sent?
Once a demand letter goes out, a few things can happen. The other side might pay or comply with what you have asked. They might respond with a counter-proposal and try to negotiate. They might dispute your claim entirely. Or they might not respond at all.
If the other side does not respond or refuses to cooperate, your next step may be to file a claim in court. In Ontario, depending on the amount in dispute, this could be Small Claims Court for claims up to $50,000, or the Superior Court of Justice for larger matters. A lawyer can help you understand which path is appropriate for your circumstances.
A Few Things to Keep in Mind
A demand letter is a useful tool, but it is not a guaranteed solution. The outcome will depend on the facts of your situation, the strength of your claim, and how the other side responds. It is also worth noting that the tone and content of a demand letter can affect how things unfold, so it is generally a good idea to have a lawyer prepare or review it before it is sent.
If you are considering sending a demand letter in Ontario, or if you have received one and are not sure what to do, speaking with a lawyer sooner rather than later is usually a good idea.
Frequently Asked Questions
Q: Do I need a lawyer to send a demand letter in Ontario?
A: You are not legally required to have a lawyer draft a demand letter, but it is generally a good idea. A lawyer can make sure the letter clearly sets out your claim, uses the right language, and does not inadvertently weaken your position. If the matter ends up in court, a well-drafted letter from a lawyer may also carry more weight.
Q: How long should I give the other side to respond to a demand letter?
A: There is no fixed rule, and the timeline will depend on the nature of the dispute. In many cases, demand letters give the other side between 7 and 30 days to respond. Your lawyer can help you decide what is reasonable given your particular circumstances.
Q: Will a demand letter always resolve the dispute?
A: Not necessarily. Some disputes are resolved after a demand letter is sent, while others are not. The outcome depends on many factors, including the strength of your claim, the other side's willingness to cooperate, and the specifics of your situation. A demand letter is a useful first step, but it does not guarantee a particular result.
Q: What if I receive a demand letter?
A: If you receive a demand letter, it is important not to ignore it. You should read it carefully and speak with a lawyer as soon as possible. A lawyer can help you understand what is being claimed, assess whether the claim has merit, and advise you on how to respond in a way that protects your interests.
