Officializing the new cadastral plan

Once the meetings have ended, the land surveying firm carries out new analyses in response to the requests for revision received from the property owners who attended them.

These analyses take several months. The land surveyor then submits the plan to the minister responsible for the cadastre, so that it can be made official, thereby ensuring a transition between the old and new cadastral plans.

Officialization process

The process leading to officialization of the cadastral renewal plan includes two periods during which the cadastral register cannot be changed, so that the minister responsible is able to update it.

Administrative freeze

This period covers 10 working days, during which no new applications for updates to the cadastre in the sector concerned can be submitted to the government.

Legal freeze

This period takes place over a period not exceeding 15 days, during which no property transactions are permitted in the sector concerned.

A legal freeze is confirmed six or seven weeks before it begins. It allows time for the land surveyor to finalize the work and for the Government to file the cadastral renewal plan in the register, to make it official.

During this period, the Government cannot accept any transactions affecting the lots concerned.

Coming into force of the new cadastral plan

Once the plan has been officialized, the Government sends a copy of it to the clerk of the municipality concerned. Copies are not sent to property owners.

However, as a property owner, you may consult the plan online, using the interactive map of the cadastre of Québec, Infolot, or the Land Register of Québec.

For additional information, please contact the land information customer relations centre.

End of the cadastral renewal work

The coming into force of the new plan marks the end of the cadastral renewal work.

However, property owners who requested a revision of the work at the consultation meeting will receive a notice of amendment from the Government.

Notice of amendment

Once the cadastral renewal plan is official, a notice of amendment will automatically be sent to you if:

  • you requested a new analysis at the meeting;
  • your lot was affected by a change to a neighbouring lot;
  • you purchased a lot in the sector covered by the work after the meeting was held. 

The notice of amendment includes a personalized document entitled Specific cadastral information on your property and an excerpt of the new plan (if amended). The land surveyor also explains the results of the additional analysis.

Lost notice or English version

Please contact us if you have lost your notice of amendment or would like an English version of it.

Please note that you will automatically receive an English version of the notice of amendment if you requested an English version of the notice of intention.

Request for revision of the official cadastral plan

At any time after the plan produced during the cadastral renewal process comes into force, property owners who have reason to believe their lots are not represented properly on the cadastre may request a revision. To do this, you must complete the form entitled Application for a cadastral revision (PDF 64 Kb) and enter the following information:

  • The number of the lot to which your request applies.
  • A detailed description of the presumed mistake, the supporting arguments and any supporting documents.
  • The date by which the revision is needed, where applicable.

The duly completed form must be sent by e-mail or by regular mail to the address shown on the back.

Documents to be sent with your request

Your request must be supported by explanations and by relevant documentation, including:

  • A certificate of location
  • A technical description
  • A survey report
  • Letters patent

If your application is imprecise or insufficiently documented, the Government may request additional information. Make sure you set out your arguments clearly.

For additional information, please contact the land information customer relations centre.

Processing of a request for revision

For the sake of fairness, the Government’s process is the same for all citizens. A copy of the request for revision is sent to the land surveyor who did the renewal work, for a second analysis.

The Government’s role

The Government’s role is to make sure the land surveyor has taken the necessary steps, during the cadastral renewal process, to carry out the land analysis properly. Its role is not to judge the land surveyor’s professional opinion, or to support the findings.

The Government cannot therefore impose its own professional opinion on the land surveyor, or the opinion of a land surveyor hired by a property owner. In addition, it does not have the power to decide disputes concerning the existence or scope of a right of ownership. Decisions such as these are up to the courts.

Possible outcomes

There are two possible outcomes to a request for revision.

The plan will be amended

The cadastral representation of your property will be amended if the changes are justified by the explanations or documents you have presented. The changes will be made by the land surveyor under his or her contractual obligations, or by the Government.

The plan will not be amended

The cadastral plan will not be amended if the documents you have presented do not provide sufficient justification. The letter you receive will contain an explanation and a description of the recourses available to you.

Disputes between neighbouring property owners

The cadastre is a tool used to represent properties on a plan for the purpose of publishing rights. A dispute between neighbouring property owners concerning their respective property boundaries can generally not be resolved by a request for revision.

In circumstances such as these, the Government can only recommend an amicable agreement with the assistance of qualified professionals. If an agreement cannot be reached, the courts must be asked to decide. Boundary determination or a motion for a declaratory judgment or acquisitive prescription may also provide a definitive solution to the problem, depending on the case.

Ask a professional in property-related matters, such as a land surveyor, a lawyer or a notary in your region, for advice.
