Frequently asked questions
What is a lot number?
It is the number that identifies a property in the Québec cadastre, for example 1 234 567. Rights on the property, such as a sale or a hypothec, are published in the land register under that number.
Where can I find a property's lot number?
It is on the municipal tax bill and in the deed of sale, which describes each lot sold. Infolot, the Québec government's free service, shows the cadastral plan and lets you check it. This tool finds it from the address, in the property assessment roll.
Why does a condo have several lot numbers?
In a divided co-ownership, each unit has its own lot, and the building's common portions have theirs. A parking space or a storage locker can also be a separate lot, or a restricted common portion attached to the unit. The roll does not say which lot is which; the complementary plan, in Infolot, or the declaration of co-ownership does.
Is the assessment roll up to date with the cadastre?
Not always. The roll is published in editions, and a lot may have been divided, merged or renumbered since the one this tool uses. Before relying on a number, check it in Infolot, which shows the current cadastre.
Does this tool replace a title search?
No. It gives the lot numbers listed on the assessment roll, and says nothing about the rights on the property, such as hypothecs or servitudes. Those rights are published in the land register, and examining the titles is the notary's work.
Is the assessed value the market value?
No. The roll reflects the market at its reference date, which comes before it takes effect, and it stays in effect for three years. A sale price can differ from it a lot, either way.
How does the tool estimate the taxes?
It applies the municipality's rates for the year, as the Ministère des Affaires municipales et de l'Habitation publishes them (in Montréal, the City's and the borough's), to the assessed value, then the school tax at the provincial rate, after the basic exemption. Sector taxes and fees, such as metered water or waste collection, are not included. It is an estimate: the tax bill is what counts.
Why do some addresses have no estimate?
The tool estimates residential taxes only. It gives none for a building that is partly non-residential, vacant land, a building of six dwellings or more where another rate applies, or where the municipality has not published its rates for the year in the ministry's data. For a condo, add the unit number.
Where does this data come from?
The property assessment roll and the year's tax rates come from the Ministère des Affaires municipales et de l'Habitation, as open data in Données Québec (licence CC BY 4.0). In Montréal, the City's and the boroughs' rates come from the Ville de Montréal, and the school tax follows the year's provincial rate. Work with a permit in Montréal comes from the City of Montréal's construction, transformation and demolition permits (licence CC BY 4.0). The tool shows no owner's name and no information about owners. Quotepart does not keep the addresses or lot numbers searched, and the results are not pages that search engines can index.
Questions about this data?
It comes from the property assessment roll, which is public, and contains no information about owners. For any question or concern, write to privacy@quotepart.ca.
