Is a formal notice mandatory before small claims?

Verified 31 July 2026 Law of Quebec and Canada General information, not legal advice

Short answer

In Quebec, the government recommends sending a formal notice (mise en demeure) before filing a small claims application, and in certain cases it is mandatory. The application form also requires proof that it was sent.

In detail

The formal notice (mise en demeure) is the letter by which you formally ask the other party to correct the situation within a specific time. The Gouvernement du Québec presents it as the first step in settling a dispute, and specifies that it is recommended before filing an application — and mandatory in certain cases.

It also has a concrete effect on money: as a general rule, interest runs from the formal notice, or exceptionally from another date the court considers appropriate. A formal notice sent early, with proof, can therefore represent several months of interest.

Finally, before filling out application form SJ-870E, you are asked to gather your exhibits, the important dates in the dispute and proof that the formal notice was sent. Without that proof, you are missing something the form calls for.

What to document

The letter itself, the date it was sent, how it was sent, the proof of receipt, and the deadline you gave. Also note the date that deadline expired: that is the starting point for everything that follows.

Put your facts in writing, free. Writing your version down early, keeping your documents dated and preparing your questions for a lawyer: the tool is there to document, never to advise.

What this page is not

This is general legal information about the law of Quebec and Canada, dated and sourced. It is not legal advice, not a strategy, and not a prediction about the outcome of a case. In Quebec, only lawyers and notaries may give legal advice (Act respecting the Barreau du Québec, ss. 128 and 133). Laws and amounts change: the official source always prevails over us.
