A Quebec letter of intent to sue (lettre d'intention de poursuivre) is a formal pre-litigation legal document by which a claimant formally notifies the opposing party of their intention to commence judicial proceedings if the claim is not resolved within a specified deadline. It serves as the final formal warning in the dispute resolution process and is drafted in compliance with the Civil Code of Quebec — particularly article 1604 C.c.Q. which recognizes formal notice (mise en demeure) as a prerequisite to most legal remedies, article 2892 C.c.Q. which provides that a formal written demand interrupts the running of prescription, and article 2925 C.c.Q. which establishes the general 3-year prescription period for civil claims. The letter also responds to the Code of Civil Procedure (C.p.c.) articles 1-7, which impose on parties and their counsel an obligation to consider private dispute resolution methods — mediation, conciliation, or negotiation — before and during judicial proceedings. A letter of intent to sue performs several crucial legal functions. First, it serves as a written demand that interrupts the prescription period under CCQ art. 2892, preventing the claim from becoming time-barred while the parties attempt to resolve the dispute amicably. Second, it complies with the good faith obligation under CCQ art. 1375 by giving the opposing party a final opportunity to remedy the situation before litigation commences. Third, it constitutes evidence of the claimant's good faith and diligence that can be produced in court. Fourth, by including a mediation offer in accordance with C.p.c. art. 1, it demonstrates the claimant's willingness to resolve the dispute without litigation, which courts view favorably in awarding costs. Fifth, by specifying the competent court and the legal consequences of non-compliance, it gives the recipient a realistic assessment of the consequences of ignoring the letter. This document is suitable for all types of civil claims in Quebec: unpaid invoices and debts, breach of contract, hidden defects in real estate or goods, property damage, civil liability for accidents or negligence, and any other monetary or non-monetary claim arising under Quebec civil law.

A Quebec letter of intent to sue (lettre d'intention de poursuivre) is a formal legal document that notifies a debtor, wrongdoer, or breaching party that the sender intends to commence judicial proceedings against them unless the disputed matter is resolved within the specified deadline. In Quebec civil procedure, this document is also known as a mise en demeure (formal demand) under article 1604 of the Civil Code of Quebec, and it is often a mandatory or strategically essential prerequisite to commencing a civil action before the Court of Quebec or the Superior Court. Under the Code of Civil Procedure of Quebec (CPC, RLRQ, c. C-25.01), articles 1 to 7 establish the general principles governing civil proceedings, including the fundamental principle that parties must attempt to resolve their disputes by private means before resorting to judicial proceedings. The letter of intent to sue serves as the formal signal that the sender has exhausted informal resolution efforts and will commence litigation if the respondent does not take concrete remedial action within the specified time. This document simultaneously serves as: (1) a formal demand letter (mise en demeure) under CCQ art. 1604, which is legally required in most cases before a debtor can be held in default; (2) a preservation notice alerting the recipient to their obligation to preserve relevant evidence under the CPC; (3) a good faith gesture demonstrating that the sender gave the other party a final opportunity to avoid litigation; and (4) a prescriptive interruption notice under art. 2892 C.c.Q., as the sending of a formal demand interrupts the running of the applicable prescription period. Under the general prescription rules of CCQ arts. 2880-2933, most civil claims in Quebec are subject to a 3-year prescription period, and the timely delivery of a formal demand letter can be critical to preserving the sender's legal rights. A well-drafted letter must identify the parties, describe the legal basis of the claim, quantify the damages sought, state the remedies demanded, set a response deadline, and provide the method of intended judicial proceedings if the demand is not satisfied.

A Quebec letter of intent to sue is needed in a broad range of civil dispute scenarios, particularly when earlier informal attempts at resolution have failed. In business and commercial settings, this letter is essential when a client or customer has refused to pay an invoice despite multiple reminders, when a contractor has failed to complete work or has abandoned a project, when a supplier has delivered defective goods that were rejected but not reimbursed, or when a business partner has breached a partnership or shareholders agreement. In the real estate context, the letter is appropriate when a seller refuses to remedy hidden defects after a formal demand letter (lettre de mise en demeure pour vices cachés), when a landlord refuses to return a security deposit without justification, when a tenant refuses to vacate premises after a valid lease termination, or when a co-owner fails to pay their share of common expenses. In personal dispute contexts, the letter is used when a borrower refuses to repay a personal loan despite a formal demand, when a party to a failed sale refuses to return a deposit, when an employer has failed to pay wages or statutory entitlements, or when a service provider has caused property damage and refuses to compensate. The letter is particularly strategic when the prescription deadline is approaching — by sending the letter, the claimant interrupts prescription under CCQ art. 2892 and preserves their right to sue without having to immediately incur court filing costs. The letter is also useful when the parties are still considering mediation or negotiation as an alternative to litigation, as it creates formal urgency while keeping the door open to amicable resolution.

A letter of intent to sue is needed in Quebec whenever a person or entity has a legitimate legal claim against another party and informal attempts to resolve the dispute have failed or are unlikely to succeed. The most common situations include: unpaid debts where a creditor has been unable to collect money owed despite multiple informal demands; breach of contract where a party has failed to perform their obligations under a commercial agreement, lease, employment contract, or services contract; property damage claims where a responsible party refuses to compensate for damage caused to the sender's property; workplace accidents or personal injury claims where an insurer or tortfeasor refuses to acknowledge liability or make adequate compensation; professional liability claims against lawyers, notaries, architects, engineers, contractors, or other professionals; landlord-tenant disputes where the TAL (Tribunal administratif du logement) or civil courts may have jurisdiction; and consumer protection disputes under the Consumer Protection Act (Loi sur la protection du consommateur, RLRQ, c. P-40.1) where a merchant has failed to honour their legal obligations. The letter is also strategically necessary when the applicable prescription period is approaching, as the formal demand interrupts prescription under CCQ art. 2892, buying the claimant additional time to assess litigation options. Additionally, the letter is often required by lawyers and notaries as a first step before they will file a judicial application on behalf of their client, and it is required by many professional liability insurers before they will accept a claim from a client against a professional. The letter may also be necessary as a first step in arbitration proceedings, where many commercial contracts require a formal written demand before arbitration can be initiated.

The key elements of a legally effective Quebec letter of intent to sue include several essential components. First, the letter must be clearly dated — the date establishes when prescription was interrupted under CCQ art. 2892 and when the response deadline begins to run. Second, a clear 'Sans préjudice' (without prejudice) notation is advisable to protect settlement discussions from being used against the sender in court. Third, complete identification of the sender (claimant): full legal name, address, phone, and email — the party who will file the lawsuit if the demand is not met. Fourth, complete identification of the recipient (defendant): full legal name and address — precise identification is crucial for the formal notice to be legally effective and for service of court proceedings. Fifth, a clear statement of the type and nature of the claim — whether it concerns an unpaid debt, contract breach, hidden defects, property damages, or other civil claims. Sixth, a precise statement of the total amount claimed in CAD, including principal, interest, and any other amounts claimed. Seventh, a factual summary of the events giving rise to the claim, with references to supporting documents such as contracts, invoices, inspection reports, or expert assessments. Eighth, the specific legal provisions under the CCQ or other applicable legislation supporting the claim. Ninth, the formal demand: exactly what the sender is requiring the recipient to do (pay a specific sum, perform an obligation, cease a specific action). Tenth, a mediation offer in accordance with CPC arts. 1-7, with proposed terms. Eleventh, the prescription date, with confirmation that this letter interrupts the prescription period under CCQ art. 2892. Twelfth, a clear deadline for the recipient to respond — typically 10-30 days — and the competent court where proceedings will be filed upon non-compliance. Thirteenth, a reference to the additional consequences of non-compliance: legal interest under CCQ arts. 1617-1619, court costs, and any other claims that will be added in the legal proceedings. Fourteenth, a good faith declaration under CCQ art. 1375 and a reservation of all rights. Finally, the signature of the sender.

The key elements of a legally effective Quebec letter of intent to sue include several essential components. First, the date of the letter — critical for establishing when formal notice was given, which is particularly important for prescription interruption under art. 2892 C.c.Q. Second, complete identification of the sender (the claimant): full legal name, address, phone, email, and their legal capacity (individual, corporation, trustee, etc.). Third, complete identification of the recipient (the respondent): full legal name and address, with any relevant capacity identification (individual, corporation, director, insurer, etc.). Fourth, a clear and factual description of the events or circumstances giving rise to the claim — what happened, when it happened, who was involved, and what was the impact on the sender. Fifth, a precise statement of the legal basis for the claim: which articles of the Civil Code of Quebec, the Consumer Protection Act, professional codes, or contractual provisions have been violated, with specific article numbers. Sixth, a quantification of the damages claimed: the total amount sought, broken down by category (direct damages, consequential damages, moral damages, interest under arts. 1617-1619 C.c.Q., professional fees, etc.). Seventh, a clear statement of the remedies demanded — payment of the specific amount claimed, performance of a specific obligation, cessation of a specific activity, delivery of a specific item, etc. Eighth, a firm but reasonable response deadline — typically 10-30 days from the date of the letter. Ninth, a specific statement of the intended judicial remedy if the demand is not satisfied within the deadline: filing before the Division des petites créances, the Court of Quebec (civil division), or the Superior Court depending on the amount and nature of the claim. Tenth, the method of delivery — registered mail, bailiff service, or acknowledged electronic delivery. Eleventh, a good faith statement under art. 1375 C.c.Q. and an openness to settlement discussions. Twelfth, the signature of the claimant or their authorized representative. The letter should be clear, professional, factual, and free of inflammatory language to maximize its effectiveness in both settlement discussions and subsequent litigation.
