A certificate of location request (demande de certificat de localisation) is a formal document by which a property owner, buyer, mortgage lender, notary, or other authorized party mandates a licensed land surveyor (arpenteur-géomètre) to prepare a certificat de localisation for a specific immovable property in Quebec. The certificate of location itself is one of the most important real estate documents in Quebec law, required for virtually every significant real estate transaction in the province. It is a technical and legal instrument prepared exclusively by a member in good standing of the Ordre des arpenteurs-géomètres du Québec (OAGQ) under the authority of the Loi sur les arpenteurs-géomètres (RLRQ, c. A-23). The certificate consists of two inseparable components: a detailed plan of the property showing its situation relative to adjacent lots, public streets and lanes, buildings, fences, and other physical features; and a written report (rapport) by the land surveyor analyzing the property's conformity with its title deeds, the applicable provisions of the Civil Code of Quebec regarding immovables and the land registry (arts. 2989-2995), the Loi sur le cadastre (RLRQ, c. C-1), and all applicable municipal and provincial zoning and construction regulations.

The certificate of location serves a fundamental role in Quebec's civil law property system. It enables the notary (notaire) preparing the deed of sale or mortgage deed to verify that the property being conveyed corresponds to what is described in the title documents and registered in the land registry, that there are no encroachments by or onto neighboring properties, that the property respects all applicable setback requirements, that no unauthorized structures exist, and that there are no unregistered easements or rights-of-way affecting the property. Financial institutions require the certificate as a standard condition of mortgage financing, as it allows them to assess the security of the property and confirm that their hypothec will be properly registered on an unencumbered title. Municipal authorities often require the certificate when processing applications for construction, renovation, or pool permits to verify that the proposed work will comply with applicable zoning and setback requirements.

The preparation of a certificate of location requires the land surveyor to conduct a physical inspection of the property, review the chain of title, consult the official cadastre and the land registry, examine applicable municipal bylaws and regulations, and prepare a professional report attesting to all observations. The surveyor's report identifies any encroachments, easements, rights-of-way, non-conformities, or irregularities detected, and the surveyor's professional opinion on their legal significance. The OAGQ's professional standards require that the certificate be signed and sealed by the responsible arpenteur-géomètre, who assumes full professional liability for its contents.

The certificate of location is deeply embedded in Quebec's unique civil law property tradition, which differs fundamentally from common law property systems in other provinces. Quebec's land registration system, based on the principle of opposabilité des droits, requires published registration of property rights to be enforceable against third parties. The certificate plays a critical role in identifying gaps between registered property descriptions and physical reality, particularly important in older Quebec cities where informal encroachments and undocumented easements are common. The cadastral renovation program of the 1990s-2000s modernized many descriptions but also created new discrepancies, making the arpenteur-géomètre's expertise essential for all significant real estate transactions in the province.

The OAGQ also maintains a professional indemnity fund protecting clients against errors and omissions in the certificate, providing an additional layer of legal protection for all parties relying on the document.

A certificate of location request is needed in Quebec in a wide range of circumstances involving real estate transactions, financing, and regulatory compliance. The most common occasion is a residential real estate sale, where the seller (or occasionally the buyer) must provide a current and up-to-date certificate to the notary before the deed of sale can be executed. Under the standard purchase promise forms used by real estate brokers affiliated with the OACIQ, the seller is typically required to provide a certificate of location current at the time of closing, meaning that if the existing certificate is outdated due to construction, additions, or other changes, a new certificate must be ordered promptly after the purchase offer is accepted to avoid delays in the closing date.

A certificate of location request is also needed when applying for a first mortgage or refinancing an existing mortgage on a Quebec property. All major financial institutions operating in Quebec — including chartered banks, caisses populaires Desjardins, credit unions, and trust companies — require a certificate of location as a standard condition of mortgage approval, as it allows their lawyers and notaries to verify the security of the property and confirm that the hypothec can be validly registered. The certificate confirms that the property exists as described in the loan application, that it has no undisclosed encroachments that might affect its value or the lender's security, and that it complies with applicable regulations.

Municipal permit applications for construction of additions, garages, swimming pools, fences, and other structures frequently require the submission of a certificate of location to demonstrate that the proposed work will comply with the municipality's zoning bylaws, particularly regarding minimum setback distances from property lines, maximum site coverage, and building height restrictions. In estate settlements, a certificate of location may be required to accurately describe the immovables forming part of the estate, to establish their value for distribution purposes, or to facilitate the registration of title transfers in the land registry. Legal disputes involving boundary encroachments, rights-of-way, easements, or property damage often require a current certificate prepared for litigation purposes, where the surveyor may also be called upon to testify as an expert witness.

The certificate of location is also specifically required in the context of Quebec government housing programs, heritage property designations under the Loi sur le patrimoine culturel (RLRQ, c. P-9.002), and agricultural land transactions subject to the CPTAQ (Commission de protection du territoire agricole du Québec). In condominium (copropriété divise) transactions, the certificate verifies unit boundaries and fractional shares of common elements. Certificates prepared for litigation purposes — boundary disputes, encroachment actions, or expropriation proceedings — require special care and detailed expert documentation to serve as reliable evidence before Quebec courts.

The certificate of location request is also essential when co-owners or partners in a real estate investment wish to subdivide or partition immovable property, as an accurate current certificate is required to support the application to the municipality and the land registry. In the context of estate administration, the liquidator (liquidateur de la succession) typically commissions certificates of location for all immovables forming part of the estate before they are sold, transferred to heirs, or subjected to new hypothecs. The certificate ensures that the legal description in the estate documents accurately reflects the current physical situation of each property, protecting both the heirs and any new purchasers from latent legal issues. Mortgage brokers and loan officers also regularly request new certificates when processing applications for second mortgages or home equity lines of credit on properties where an existing certificate may be outdated.

The key elements of a Quebec certificate of location request ensure that the land surveyor has all the information necessary to prepare a thorough and accurate certificate. First, the date of the request must be clearly stated, as it establishes the timeline for the work and any associated deadlines. Second, the requester must be fully identified with their legal name, address, phone number, email address, and their capacity — whether they are the buyer, owner, mortgage lender, notary, real estate broker, or another party — since the purpose of the certificate and any specific requirements may vary depending on the requester's role in the transaction. Third, if the requester is not the current registered owner of the property, the owner's full legal name and address must be provided, as the land surveyor will need to contact the owner to arrange access to the property for the physical inspection and to review their title documents.

Fourth, precise property identification is critical and must include the full civic address, the name of the municipality, the cadastral lot number(s) as they appear in the Cadastre du Québec, and the registration division (circonscription foncière), which identifies the territorial jurisdiction of the Bureau de la publicité des droits where the property's title documents are registered. The type of property (single-family house, condominium, duplex, vacant land, commercial building, etc.) should also be specified, as different property types may require different survey approaches and have different regulatory frameworks. Fifth, the primary purpose of the certificate must be clearly stated, since the scope of the work and any specific requirements — such as compliance with a lender's underwriting guidelines or a municipality's permitting requirements — depend directly on the intended use of the certificate.

Sixth, information about any existing certificate must be provided, including its date and the name of the surveyor who prepared it. A certificate more than five years old, or one prepared before any construction, renovation, or boundary change, may need to be replaced with a new one. Seventh, the name and OAGQ membership number of the appointed land surveyor or surveying firm should be stated to confirm that a qualified professional has been engaged. Eighth, any required completion deadline must be specified, particularly when the certificate is needed before a real estate closing date, a financing approval deadline, or a municipal permit application deadline. Ninth, any known concerns, irregularities, or special instructions must be communicated to the surveyor, including suspected encroachments, recent construction without permits, changes in boundary features, or other issues that may require particular attention. Finally, a good faith clause under art. 1375 C.c.Q. and a governing law clause specifying Quebec law ensure the professional relationship is properly grounded in Quebec civil law.

Beyond the essential elements, the requester should specify whether the certificate is for new construction or an existing property, since construction-phase certificates serve different purposes. The request should confirm whether it covers land only or also structures. Known encroachments — neighbor fences crossing property lines, buildings extending beyond boundaries, informal shared driveways — should be explicitly mentioned so the surveyor can focus attention accordingly. Any prior certificate should be provided for reference. Registered easements or rights-of-way in title documents that the surveyor should verify on the ground should be identified. Finally, the requester must confirm property access will be granted on the agreed inspection date, as failure to provide access delays the process and incurs additional professional fees.
