Property Assessment Roll

The current roll covers the years 2023, 2024 and 2025.

The most recent rolls (2026-2027-2028) will be effective from January 1, 2026.

What is the property assessment roll?

The roll contains an inventory of all properties and provides for each property:

• Owner’s name
• Address
• Building description
• Property value (also known as assessed value)

This value represents the market value of your property at a given date but is used for tax purposes only. It does not constitute a valuation for sale.

Impact of assessment on property taxes 

The assessment roll serves as the basis for calculating municipal and school taxes.

An increase in the value of your property does not automatically translate into an equivalent increase in your municipal tax bill. 

The City adjusts tax rates to reflect changes in values. They are defined annually in the municipal budget, so as to obtain the revenues expected to provide the City’s services.
