Mise en demeure (Quebec demand letter)

In brief

A mise en demeure, called a demand letter or formal notice in English, is a letter in which you require a person or business to perform an obligation (pay, repair, stop a behaviour) within a set time, failing which you will exercise your remedies. In Quebec, it must be in writing and allow sufficient time (art. 1595 C.C.Q.). Anyone can write and send one themselves.

Definition

A mise en demeure is an extrajudicial demand: a step taken outside the courts, before any lawsuit. It "puts the debtor in default", meaning it formally establishes that they have not done what they owed, and gives them a last chance to do it.

Article 1594 C.C.Q. (excerpt)
« A debtor may also be put in default by an extrajudicial demand to perform the obligation addressed to him by his creditor, a judicial application filed against him or the sole operation of law. »

The "creditor" is the person who is owed something (a tenant waiting for repairs, a business waiting for payment). The "debtor" is the one who must perform. A demand letter can cover almost any obligation: unpaid rent, work not done, an overdue invoice, an unreturned deposit, a breached contract, a neighbour dispute.

What a demand letter changes

It formally marks the debtor's default, on a date you can prove.
For a sum of money, interest runs from the date of default, without you having to prove any injury (art. 1617 C.C.Q.).
It is usually the step before an application to the Tribunal administratif du logement or small claims, and it shows your good faith.
Many disputes settle at this stage, without a hearing.

In some cases the debtor is in default "by operation of law", without a letter: urgency, an obligation that was only useful within a certain time, a clear refusal to perform or repeated failures (art. 1597 C.C.Q.). In practice, sending a demand letter remains the safest way to document the default.

Who can send one

Anyone can write and send their own demand letter: the law requires neither a lawyer nor a bailiff, and the letter has the same legal value whether you or a professional writes it. A lawyer is still useful for a complex file or a large amount. Do you need a lawyer for a demand letter?

What your demand letter must contain

Your full contact details and those of the recipient
The date it was written
The words "without prejudice" (sous toutes réserves), which signal the letter is neither an admission nor a waiver
A clear, chronological account of the facts, with dates and amounts
Your specific demand (repair, payment, stopping a behaviour)
A reasonable deadline to comply, usually 10 days
The consequences of non-compliance (legal action, damages)
Your signature

Article 1595 C.C.Q.
« An extrajudicial demand by which a creditor puts his debtor in default must be made in writing. The demand must allow the debtor sufficient time for performance, having regard to the nature of the obligation and the circumstances; otherwise the debtor may perform the obligation within a reasonable time after the demand. »

Beyond these two requirements (writing and sufficient time), the letter need not follow any particular form.

Steps to write a demand letter

01
Identify the recipient
Name the person or business concerned, with their full contact details and yours. For a business, use its legal name and head office address.
02
Set out the facts
Describe the situation chronologically, with precise dates and amounts. Stick to verifiable facts: a measured tone helps your credibility if a judge reads the letter.
03
Make a specific demand
State exactly what you require: "carry out the bathroom plumbing work" or "refund $850" rather than "fix the problem."
04
Set a reasonable deadline
Allow sufficient time for performance, most often 10 days. It can be shorter in an emergency or longer for a complex obligation.
05
Sign, date and keep a copy
Date and sign the letter, add "without prejudice" and keep a copy of the version you send.
06
Send it with proof of receipt
Choose a sending method that leaves a record: without proof of receipt, the recipient can claim they never got your letter.

How much time should you allow?

Article 1595 C.C.Q. requires sufficient time, having regard to the nature of the obligation and the circumstances. In practice, 10 days is generally considered reasonable. It can be shorter for an emergency (no heat in winter) or longer for major work.

A deadline that is too short does not make the letter invalid: the debtor may then perform within a reasonable time after the demand. A deadline that is too short therefore delays your remedies instead of speeding them up. How much time to allow in a demand letter

How to send it and prove receipt

Sending it matters as much as what it says. The usual methods, and the proof each one produces:

Registered mail (Canada Post): delivery confirmation and signature, 2 to 3 business days
Bailiff (huissier de justice): hand delivery and a record of service, the strongest proof
Certified email: immediate sending and a timestamped report (sending, delivery to the recipient's server, opening when detected), useful if you already communicate with the recipient by email
Hand delivery: signed acknowledgment of receipt or a witness

If the demand letter goes unanswered

Once the deadline has passed, you can go to the competent tribunal: the Tribunal administratif du logement for a residential lease dispute, or the Small Claims Division of the Court of Québec for a claim of $15,000 or less. The letter and its proof of receipt then become exhibits in your file. After the demand letter: the next steps

Frequently asked questions

What is a mise en demeure in English?

It is a demand letter, also called a formal notice: a letter in which one person requires another to perform an obligation within a set time, announcing the remedies that will follow otherwise. In Quebec, it must be in writing and allow sufficient time (art. 1595 C.C.Q.).

Is a demand letter required before suing?

In most cases, yes in practice: the debtor must be in default before you can claim damages, and the letter is the usual way to get there. There are exceptions where the debtor is in default by operation of law (art. 1597 C.C.Q.), but sending the letter avoids any argument on that point.

How long should you wait for a response?

The recipient must comply within the deadline you set, most often 10 days. They are not required to reply in writing; if they do nothing within the deadline, you can move to the next step.

Can you send a demand letter by email?

Yes. The law requires writing, not paper. What matters is being able to prove receipt. An ordinary email leaves little trace; a certified email produces a timestamped report. If you have never exchanged emails with the recipient, double up with registered mail.

How much does a demand letter cost?

Writing it yourself with a template costs nothing. For sending, expect about $14.59 before taxes for registered mail, $75 to $150 or more for a bailiff, and $14.99 for certified email with Locato. A demand letter written by a lawyer generally costs between $500 and $1,500.

Can a demand letter be written in English in Quebec?

Yes. No rule requires French for a demand letter between private parties. Write it in a language the recipient understands: the goal is that they cannot claim they did not understand it.
