Property Taxation – New 2021 Assessment Rolls in Quebec

Deadline: April 30, 2021

Last September, some municipalities deposited and made available online their new property assessments for the 2021 triennial rolls. The values entered on these rolls reflect market conditions as of July 1, 2019. These new assessment rolls are effective from January 1, 2021 to December 31, 2023.

There are new assessment rolls effective in 2021 in more than 350 municipalities in Quebec, including:

  • Berthierville
  • Cowansville
  • Drummondville
  • Gatineau
  • La Tuque
  • North-Hatley – Hatley – Potton
  • Rosemère
  • Sainte-Adèle
  • Saint-Faustin-Lac-Carré

Two municipalities have elected to extend their rolls for a year: Baie-Saint-Paul, Huntington and Ormstown

Here are some of the appraisal parameters that we use to obtain assessment reductions / tax burden:

  • market rents;
  • vacancy and bad debt allowances;
  • operating expenses;
  • capitalization rates;
  • excess vacancy;
  • needed major repairs;
  • sales of comparable properties;
  • functional and economic obsolescence;
  • non-taxability of certain items;
  • qualification and identification of the electrical and mechanical systems of manufacturing facilities (lighting, heating, air conditioning, ventilation, water, sewer) that are “normally necessary” for occupants and building services.
  • review the taxation class and make sure it is appropriate which may have an impact on your tax burden.


The deadline for filing applications for review to contest 2021 assessments is April 30, 2021.

Failure to file by the deadline is equivalent to acceptance of these values for the next three years.

COVID & Municipal Assessments

The 2021 triennial roll having a reference date (July 2019) prior COVID (March 2020) does not take into consideration the COVID situation or any related impacts. However, if your property has experienced any issues prior COVID, or if the situation has deteriorated drastically since then, we would strongly suggest that we review your assessment to make sure that we are not missing out on any opportunity to lower your tax burden.
