Promise to Purchase (Quebec)

A Quebec Promise to Purchase (Promesse d’achat) is a preliminary legal agreement governed by arts. 1396-1397 of the Code civil du Québec (CCQ). This document serves as a binding commitment by the promising buyer (promettant-acheteur) to purchase immovable property from the promising seller (promettant-vendeur), subject to the conditions and within the timeframes the document establishes. Under art. 1396 CCQ, the promise to enter into a contract is binding and gives the beneficiary the right to demand conclusion of the promised contract — the promesse is not a mere expression of interest but a legally enforceable preliminary agreement.

The promesse d’achat is the most widely used vehicle for initiating real estate purchases in Quebec. It sets out all essential terms that will eventually be incorporated into the notarial deed of sale: complete party identification, the precise cadastral description of the immovable, the agreed purchase price in Canadian dollars, the deposit amount and its trustee, the conditions precedent for financing and building inspection, the acceptance deadline, and the consequences of non-performance under art. 1397 CCQ.

There is a technical distinction in Quebec civil law between the promesse d’achat — technically a unilateral promise under art. 1396 by which only the buyer is bound until the seller accepts — and the offre d’achat — which is bilateral from the moment both parties sign. In practice, these terms are used interchangeably by real estate practitioners, brokers, and courts in Quebec, and both forms create binding legal obligations. The duty of good faith under art. 1375 CCQ applies from the moment the promesse is signed and continues throughout negotiations, the satisfaction of conditions, and up to the signing of the notarial act. The warranty against hidden defects under art. 1726 CCQ, which will apply to the eventual sale, is an implicit component of the transaction framework established by the promesse. Certified members of the OACIQ (Organisme d’autoréglementation du courtage immobilier du Québec) use standardized forms, but private parties may draft their own promesse provided CCQ requirements are met.

You need a Promesse d'achat whenever you are ready to make a firm commitment to purchase immovable property in Quebec, but require one or more conditions to be satisfied before the sale becomes unconditionally binding. It is the standard initiating document for residential real estate transactions involving houses, condominiums, duplexes, triplexes, income properties, vacant residential lots, and rural or recreational land.

The document is essential when the buyer needs time to arrange mortgage financing: a financing condition allows the buyer to withdraw and recover the deposit if a financial institution does not approve the mortgage within the agreed timeframe. Similarly, a building inspection condition gives the buyer the right to have the property inspected by a certified building inspector (inspecteur en bâtiment) and to withdraw if serious defects are discovered. Both conditions protect the buyer from being legally bound to complete a transaction that is financially or structurally unsound.

The promesse d'achat is also appropriate when the buyer must sell their current property before having sufficient funds to complete the purchase — in this case, a condition of sale of the buyer's existing property may be included. When the seller needs time to consult their own advisers, obtain a court authorization (for example, in a succession context where a probate order may be required), or obtain consent from a co-owner, the acceptance deadline in the promesse accommodates this process.

For transactions involving commercial or industrial property, buyers often need a due diligence period to review leases, environmental site assessments, municipal permits, and financial records before waiving conditions. The promesse d'achat provides the legal framework for this process. Even for parties transacting without a broker, executing a promesse d'achat before visiting the notary confirms the parties' agreement is clearly documented and enforceable, reducing the risk of disputes over what was agreed during verbal negotiations. The document should be signed well in advance of the notarial closing — typically four to eight weeks — to allow all conditions to be satisfied.

Quebec Promise to Purchase (Promesse d'achat) — the following statutes and regulatory bodies govern this document: the Code civil du Québec (CCQ), particularly articles 1396-1397 (promise to contract), article 1711 (deposit/arrhes), article 1375 (good faith), article 1726 (warranty against hidden defects), and article 2938 (publication of real rights at the Registre foncier du Québec); the OACIQ (Organisme d'autoréglementation du courtage immobilier du Québec, under the Real Estate Brokerage Act, RLRQ c. C-73.2) regulates real estate brokers who use standardized promise forms; the Chambre des notaires du Québec (under the Notaries Act, RLRQ c. N-3) oversees the notary who must authenticate the final deed of sale; the Registre foncier du Québec (maintained under CCQ article 2969) records all published real rights; the Commission des droits de la personne et des droits de la jeunesse (CDPDJ, under the Charter of Human Rights and Freedoms, RLRQ c. C-12, section 10) prohibits discriminatory refusals in real estate transactions; Revenu Québec administers the land transfer tax (taxe de bienvenue under the Act Respecting Duties on Transfers of Immovables, RLRQ c. D-15.1); the Superior Court of Quebec (section 34, Code of Civil Procedure, RLRQ c. C-25.01) adjudicates disputes; and the Tribunal administratif du logement (TAL, formerly the Régie du logement, under the Act Respecting the TAL, RLRQ c. T-15.01) handles residential tenancy matters arising from the transaction.

A complete and enforceable Quebec Promise to Purchase addresses the following key elements. Identification of parties: the full legal names, addresses, and contact information of the promettant-acheteur and the promettant-vendeur; if either party is a legal person, the enterprise number and the name of the authorized signing officer must be stated. Property description: the complete cadastral designation — lot number, cadastral circumscription, and municipal address — as it appears in the Registre foncier du Québec, together with a list of inclusions and exclusions (appliances, fixtures, movables forming part of the sale).

Purchase price: the total price in Canadian dollars, expressed clearly, and the amount of the deposit (arrhes) to be paid upon acceptance per art. 1711 CCQ, identifying the trustee who will hold the deposit until notarial closing. Financing conditions: the desired mortgage amount, the maximum acceptable interest rate, amortization period, the name of the financial institution(s) to be approached if desired, and the deadline by which approval must be obtained — failure triggers nullity of the promise and refund of the deposit. Building inspection conditions: the deadline for completing the inspection by a certified inspector and the specific criteria that entitle the buyer to withdraw.

Acceptance deadline: the date and time by which the seller must accept the promise in writing; after this deadline, the offer lapses automatically. Consequences of non-performance per art. 1397 CCQ: if the promisor fails to honour the promise, the beneficiary is entitled to damages and may seek specific performance or an equivalent remedy through Quebec courts. Notary designation: the name of the notary who will receive the notarial deed of sale, and the anticipated signing and possession dates. The bonne foi obligation per art. 1375 CCQ, the warranty against hidden defects under art. 1726 CCQ that will apply to the completed sale, and the applicable law clause confirming the Code civil du Québec governs the promise complete this essential document.
