Taxation and Finance Quebec 3 Minutes Read · published May 26, 2026 Flag of Quebec

In Ahuntsic-Cartierville, Quebec, property owners who disagree with their municipal property assessment can seek a review and file appeals through the city process. This guide explains the practical steps to review an assessment, gather evidence, submit a formal complaint or request, and pursue administrative review or appeals using the official Montreal procedures and borough contacts.

Start by comparing your assessment notice to comparable properties and the municipal roll.

Who handles assessments and appeals

The City of Montreal administers property assessment information and provides the procedures to contest a property valuation; the borough of Ahuntsic-Cartierville handles local inquiries and can direct you to the city assessment contestation process[1].

Common grounds to dispute an assessment

  • Incorrect property description or boundaries.
  • Errors in building size, number of units, or permitted use.
  • Comparable properties show materially lower values.

Penalties & Enforcement

Municipal enforcement for assessment matters focuses on correct placement on the roll and collection of municipal taxes based on the roll; fines and penalties for related bylaw breaches are detailed by the city and vary by offence. Specific fine amounts and escalation for assessment contestation or related bylaw violations are not specified on the cited municipal contestation page[1]. For enforcement of bylaw offences unrelated to assessment (for example, permits or construction infractions), consult borough enforcement pages for amounts and procedures[2].

If you miss a formal deadline you may lose the right to appeal.

Applications & Forms

The City of Montreal publishes the procedure to contest an evaluation and where to submit a complaint or request; the municipal page provides links to the official contestation process and any required online forms or contact points[1]. If a dedicated form or fee is required for a formal appeal, that information appears on the city contestation page or the borough contact page; if the page does not list a form or fee explicitly, state "not specified on the cited page" when relying on that source.

  • How to start: follow the city contestation instructions and complete any online request form indicated on the official page[1].
  • Deadlines: check the municipal contestation page immediately for any filing deadlines; if not listed, the city page should be consulted directly for time limits[1].
  • Local contact: borough office for Ahuntsic-Cartierville for procedural help and local records[2].

How the review and appeal process works

Typical steps are an initial review request, submission of evidence (photos, comparables, plans), administrative review by the city assessment unit, and if unresolved, escalation to the next review body identified by municipal procedure. Exact bodies and timelines are described on the City of Montreal contestation page and borough guidance[1][2].

Action steps

  • Compare your property record with similar properties and assemble evidence.
  • Open the official contestation procedure on the City of Montreal site and complete any indicated form[1].
  • If the administrative review is unfavourable, follow the city page directions to escalate to the designated review body or hearing.
