Montreal Property Assessment: How to Check Your Assessed Value

|

Find your property’s assessed value in under a minute.

What is assessed value?

Assessed value is the amount assigned to your property by your municipality for tax purposes.

It’s calculated using standardized models and historical market data, often based on a past valuation date rather than current market conditions or your home’s unique features.

Check your assessed value to understand how your property is evaluated for taxation.

How Assessed Value Is Calculated

Municipal assessed values are calculated using mass appraisal systems designed for taxation – not for setting a sale price.

Instead of evaluating each property individually in real time, municipalities analyze large groups of properties using standardized models and historical market data from a specific valuation date.

Assessments typically consider factors such as:

  • Location
  • Lot size
  • Property type
  • Square footage
  • Age of the building
  • Basic structural characteristics

Because assessments are conducted on a broad scale, they usually do not account for:

  • Recent renovations or upgrades
  • Interior condition
  • Unique features
  • Current buyer demand
  • Rapid market changes

Assessed value is primarily used to determine property taxes. It reflects a calculated value at a fixed point in time – not necessarily what a buyer would pay today.

For a real-time estimate based on current market activity, a Comparative Market Analysis (CMA) provides a more accurate picture.

Frequently Asked Questions

Everything you need to know about assessed value

Assessed value is the value assigned to your property by your municipality for property tax purposes. It is used to calculate how much property tax you owe – not necessarily what your home would sell for on the open market.

No. Assessed value is determined by the municipality using mass appraisal methods and is often based on past valuation dates. Market value reflects what a buyer is willing to pay for your home today based on current demand, condition, and comparable sales. In many cases, the two numbers can be significantly different.

Municipal assessments are not updated in real time. In fast-moving markets, home prices may rise faster than assessment updates, which can make your assessed value appear lower than current market value.

Yes. In slower markets or after price corrections, assessed values may lag behind market conditions. If this happens, homeowners sometimes appeal their assessment.

Municipalities evaluate properties using standardized formulas that consider factors such as location, lot size, square footage, and property type. Unlike a CMA, assessments do not typically account for recent renovations, interior condition, or current buyer demand in detail.

No. Buyers focus on market value — what similar homes have recently sold for – not the municipal assessment. While some buyers may look at it for reference, it does not determine what your home will sell for.
