Have you received a request to participate in the collection of economic data? How will this information help determine the value of your property? What documentation do you need to provide? Here’s what you need to know.

The collection of economic data is one of the means of assessing the property value of income properties. The data gathered contribute to the production of the property assessment roll for the 19 boroughs and the 15 linked cities. The collection takes place every three years, before a new roll is tabled.

How the value of income properties is calculated

Economic data are collected for income properties, which total about 33,000 in Montréal. The information gathered is used to determine the value of your property based on real estate market conditions and the specific characteristics of your building. For example, you will be asked for information such as income, expenses or a list of tenants for your property.

Property value is determined using the income approach. This method involves estimating the value of a property based on the net income it can generate, compared with similar properties and according to a reference date. For the next property assessment roll, effective January 1, 2026, the reference date is July 1, 2024.

How to provide the requested information

If the city wants to collect data about your property, you will be mailed the procedure to follow according to your situation starting May 31, 2024. 

For owners of buildings with 6 to 11 above-ground units, you must provide this information online.

The collection economic data period for owners of buildings with 6 to 11 units is now over.
