Mise en demeure in English: your demand letter in Québec

Maybe a letter titled « Mise en demeure » just landed in your mailbox, or maybe you need to send one and only know the term "demand letter" from elsewhere in Canada. This page covers what the document is, the three English names for it, what it must contain under Québec law, what to do if you received one, and how to send yours with proof of receipt.

You received a mise en demeure: what it is and isn't

A mise en demeure is not a judgment, a lawsuit or a court order. It's a formal letter (usually the last step before legal proceedings) telling you what the sender claims, what they want you to do, and by when. The TAL describes it as a letter ordering its recipient to comply with an obligation or correct a situation, within a set time.

Take it seriously, but don't panic. You generally have three options: comply within the deadline, respond to negotiate or propose a solution, or contest the claims in writing. Ignoring it doesn't make it go away: silence usually strengthens the sender's file for the next step. Respond in writing and keep proof that you did; you may respond in English or in French, whichever you prefer.

You need to send one: what the law requires

Article 1595 of the Civil Code of Québec sets only two requirements: the extrajudicial demand "must be made in writing" and must allow the debtor "sufficient time for performance, having regard to the nature of the obligation and the circumstances." No lawyer, no notary, no specific format: a clear written letter with a reasonable deadline (often 10 days) is what the law asks for.

In practice, your letter should state:

• The facts: what happened, with dates
• Your precise demand: repair, pay, stop: with the amount if applicable
• A sufficient deadline to comply (often 10 days)
• The words "without prejudice" (« sous toutes réserves » in French)
• The date, your signature and your contact information

Three English names, one document

There is no single official translation: three terms coexist, and all refer to the same document:

1. 01

   Demand letter: everyday usage

   The most common term in North America, and the one lawyers, insurers and recipients outside Québec will recognize immediately.

2. 02

   Formal notice: the TAL's term

   The English site of the Tribunal administratif du logement translates mise en demeure as formal notice. Use this term in a Québec housing context, especially if your file may end up before the TAL.

3. 03

   Extrajudicial demand: the Civil Code's term

   The official English version of article 1595 C.c.Q. speaks of an "extrajudicial demand by which a creditor puts his debtor in default." This is the precise legal term you'll find in statutes and translated judgments.

Can it be written in English?

Yes. Article 1595 requires a writing and a sufficient deadline: it imposes no language. A demand letter written in English has the same value as one written in French. The sensible rule is to write in a language the recipient clearly understands, since the letter's purpose is to inform them and give them a real chance to comply.

If you are writing on behalf of a business, keep in mind that the Charter of the French language may govern some business communications; when in doubt, enclose a French version alongside the English one.

Sending it with proof of receipt

Whatever the language, the letter only helps you if you can prove the recipient got it. The TAL's own guidance lists several valid delivery methods, including registered mail and email with proof of receipt. Every Locato template exists in English and French: fill it in free, then send it by certified email for $14.99 with a timestamped proof report consistent with Québec's LCCJTI : confirmation of sending, delivery, and opening detection where possible.

One caveat: the recipient should use email as a regular means of communication. If you've never exchanged emails with them, double up with registered mail.
