How to use this guide
The right question at the right time protects your decision.
Here are the main legal frameworks, regulations and documents that may affect a residential or commercial sale in Quebec. The applicable rule depends on the property, its use and your situation.
01 · Before signing
The mandate and the information provided from the outset shape the entire transaction.
Known facts that could influence the property’s value, use or condition.
Useful titles, plans, invoices, permits, leases and condominium documents.
With an understood mandate, realistic deadlines and the right professional’s advice at the right time.
02 · The property file
15 legal reference points qui peuvent changer votre vente.
Each card answers three questions: which rule applies, what it requires of you, and what can happen if an important element is overlooked.
Quebec Civil Code: good faith and duty to inform
The rule. The parties must act in good faith. The seller must disclose relevant information they know about the property and avoid any misleading presentation.
For you. A known infiltration, structural problem or non-compliant use must be disclosed, even if you hope no one notices. Silence can lead to renegotiation or a claim.
Legal warranty of quality and hidden defects
The rule. Articles 1726 to 1730 C.C.Q. impose a warranty against hidden defects that make the property unfit for its intended use or reduce its usefulness so much that the buyer would not have purchased it, or would have paid less.
For you. A serious defect, existing before the sale and not apparent, may lead to a price reduction, damages or resolution of the sale. An inspection and precise disclosure reduce uncertainty without eliminating the warranty.
Public-law restrictions
The rule. The seller also warrants certain violations of public-law restrictions affecting the property and outside ordinary private-law rules, subject to the exceptions in article 1725 C.C.Q.
For you. A specific zoning designation, flood zone, shoreline strip or use restriction can change the property’s value and the buyer’s project. Identify them in the title documents, location certificate and municipal files.
Titles, mortgages and servitudes
The rule. The land register reveals published real rights and charges: mortgage, right of way, view rights, encroachment or reserve. The seller must be able to convey clear title and allow the discharge of security at closing, unless otherwise agreed.
For you. A shared driveway or forgotten mortgage can delay the notary, change net proceeds or prevent the buyer from obtaining financing. Have the titles reviewed early.
Real estate brokerage law and OACIQ
The rule. A person acting as an intermediary in a real estate brokerage contract generally must hold the required licence. The broker must act with loyalty, diligence and competence, present promises to purchase and disclose certain interests or compensation.
For you. The brokerage contract sets out the mandate, duration, compensation and services. Also understand dual-representation or disclosure situations before signing.
Seller’s declarations about the property
The rule. The OACIQ seller’s declaration form is part of the seller’s brokerage contract and lets the buyer obtain details about the property’s condition. It must be completed in good faith, to the best of your knowledge.
For you. Answer the questions, even when the answer is “I don’t know,” and attach relevant invoices, reports or notices. An incomplete disclosure can suggest reluctance and complicate the transaction.
Location certificate
The rule. This surveyor document describes the current position and condition of the property relative to title, boundaries, encroachments, servitudes, risk zones and applicable regulations. It is generally provided by the seller.
For you. A certificate that no longer reflects reality, including a new fence, pool, addition or shed, may require an update and delay signing before the notary.
Condominium: syndicate certificate
The rule. Since August 14, 2025, article 1068.1 C.C.Q. provides that a seller of a fraction must timely deliver a syndicate certificate regarding the condominium’s condition. The regulation specifies, among other things, funds, charges, claims, work and litigation to be documented.
For you. An insufficient contingency fund, special assessment or planned major work can change the price and the buyer’s ability to close. Request the certificate, declaration of co-ownership, minutes and financial statements early.
Agricultural land and CPTAQ
The rule. The Act respecting the protection of agricultural land and agricultural activities governs the use, subdivision and alienation of lots in an agricultural zone. Some transactions require CPTAQ authorization or must comply with a specific exception.
For you. A residence, vacant lot, wooded land or subdivision project does not automatically have the same rights. A promise conditional on the required authorization better protects the schedule and expectations.
Environment and contaminated land
The rule. The Environment Quality Act provides for characterization studies and, when thresholds are exceeded, registration of a contamination notice in the land register in the situations covered.
For you. A former garage, tank, workshop, business or suspect fill may require a study, remediation plan, use restrictions or a financing condition. Disclose known facts and have the risk assessed.
Septic systems and wastewater
The rule. The Regulation respecting wastewater disposal and treatment for isolated dwellings governs the installation, capacity and compliance of private systems. The municipality is involved, including for permits.
For you. An undersized septic tank, a chamber added without sufficient capacity or a lack of documents can limit use and affect price negotiations. Gather available plans, permits, pumping records and reports.
Zoning, permits and municipal acquired rights
The rule. Municipal regulations govern zoning, construction, subdivision, uses, pools, accessory buildings and required certificates. Acquired rights depend on specific facts and rules.
For you. Do not present a dwelling, home office or addition as legal without verification. Written confirmation from the municipality can prevent a promise based on an impossible use.
Leases, tenants and income properties
The rule. A sale does not automatically end leases: the buyer generally becomes the new landlord. Visits must respect privacy and, for a sale visit, at least 24 hours’ notice and the time slots set by the TAL.
For you. Give the broker and notary the leases, notices, rent records and agreements. In certain buildings with more than twelve units, TAL authorization may also be required before the transfer.

Taxes, duties and tax consequences
The rule. The transfer duty is normally payable by the new owner, but the seller must plan for tax adjustments and provide the necessary information. A sale of a new home or one that has undergone major renovations may be subject to GST and QST.
For you. A capital gain generally must be declared; a rushed residential resale within 365 days may be treated as business income, subject to exceptions. Have a tax professional confirm the treatment.
Cultural heritage and right of first refusal
The rule. A classified building or property located in a classified heritage site may require prior authorization, a notice of sale delivered 60 days in advance and a government right of first refusal.
For you. A heritage property can be sold, but the timing and the buyer may trigger a specific process. Check the status before publishing or accepting a promise to purchase.
