When to File a Demand Letter — And When Not To
A practical guide to using demand letters for debt, contracts, and disputes.

If you’re owed money, facing a contract dispute, or dealing with someone who isn’t holding up their end of an agreement, you may have heard about using a demand letter. But is it always the right move? As Ontario paralegals, we often see clients who could benefit from a demand letter — and others where it may not be the right first step. This guide will help you understand when to use a demand letter, and when not to, so you can make a smart legal decision.
What Is a Demand Letter?
A demand letter is a formal written notice sent to another party, asking them to take (or stop) a specific action. Most often, it’s used to:
- Request payment of an outstanding debt.
- Enforce a contract or agreement.
- Resolve disputes before going to court.
- Provide evidence of your attempts to settle matters reasonably.
In Ontario, a properly drafted demand letter can save you time, money, and stress — and it often leads to a resolution without needing a lawsuit.
When You Should File a Demand Letter
1. When You’re Owed Money
If someone hasn’t paid an invoice, loan, or service fee, a demand letter shows you’re serious. It can often prompt payment without further legal steps.
2. When Contracts Are Broken
Whether it’s a landlord/tenant agreement, service contract, or business deal, a demand letter can formally outline how the other party has failed to meet their obligations.
3. When You Want to Avoid Court
Courts often expect you to try reasonable steps before filing a claim. A demand letter proves you attempted resolution, which strengthens your case if it moves forward.
When You Shouldn’t File a Demand Letter
1. When Emotions Are High
If the dispute is deeply personal (like a family matter), sending a legal letter too soon may escalate tensions instead of solving the issue.
2. When There’s No Legal Basis
If the claim is weak or unsupported, sending a demand letter could backfire. The other side may call your bluff — or worse, use it against you later in court.
3. When Time Is Critical
If a limitation period is about to expire, filing a claim right away might be safer. A demand letter alone won’t stop the clock on deadlines.
