A municipal assessment is not a current selling price

It is established for the property-tax system using a specific reference date. A comparative factor or uniformized value does not guarantee current market value.

How this calculator works

  1. Change is calculated between the previous and current assessment.
  2. Uniformized assessment is the entered roll value multiplied by the comparative factor.
  3. The investigation signal uses the size of the change, reference-date lag and distance of the factor from 1.

Limits and amounts to confirm

Public-roll coverage varies by municipality. To avoid uncertain address matches, ProprioValeur does not claim province-wide automatic lookup; always use your municipality’s official roll.
