Filing an Assessment Complaint

Filing an Assessment Complaint

The Canmore Assessment Review Board (ARB) is an independent quasi-judicial board (similar to a legal body) established in accordance with Part 11 of the Municipal Government Act and the Assessment Review Board Bylaw. It is an impartial tribunal that is responsible for making decisions regarding property assessment complaints.

Two types of assessment review boards hear property assessment appeals:

  • Local Assessment Review Board (LARB)
    • Residential property with three or fewer dwelling units
    • Farmland
    • A tax notice other than a property tax notice
  • Composite Assessment Review Board (CARB)
    • Residential property with four or more dwelling units
    • Non-residential property

Filing an Assessment Complaint

Each year a Property Assessment Notices or a combined Notice of Assessment and Property Tax is mailed by the Municipality. This is your opportunity to review the assessed value of the property and to address any concerns prior to receiving your Property Tax Bill.

Assessment complaints must be received by the final date for the complaint indicated on your Notice (within 60 days of the date of mailing). The complaint form and correct filing fee must be received at the address indicated on the Notice no later than this final date or the complaint is invalid, and the Board will not hear the complaint. An assessment complaint is not an appeal for lower taxes or tax rates.

Your complaint may be about any of the following, as shown on the Assessment Notice:

Both forms are also available on the Alberta Property Assessment Complaints and Appeals webpage.

The required forms must be completed as prescribed. Significant errors could lead to the complaint being dismissed as invalid.

Please note: It is important to complete all fields on the complaint form that are relevant to your property. This will help the Board Clerk schedule the appropriate amount of time for your hearing.

The Assessment Review Board must not hear any matter regarding an issue that is not identified on the complaint form. This means you cannot introduce new evidence or issues at the hearing that have not been previously disclosed.

  • Your complaint must explain why you think the information or assessed value shown on your Notice is incorrect.
  • If you disagree with the assessed value, you must include what you believe the assessed value should be.
  • Your complaint must be submitted to the address shown on the Notice along with the required filing fee.
  • The complaint will then be forwarded to the ARB Board Clerk for further handling until the complaint proceeds to a scheduled hearing or is withdrawn.

If you are being represented by an Agent, the signed Agent Authorization Form must be submitted with the Complaint Form.

Payment can be made by cash, cheque, or debit, made payable in Canadian funds only to Town of Canmore.  Payments by credit card are also accept up to a limit of $1300.00.

Appeal fees will be refunded if the Assessment Review Board decides in favour of your appeal.

Property Type Fee
Residential Properties of 3 Dwellings or Fewer $  50 per roll
Multi-Family Residential of 4 or More Dwellings $ 650 per roll
Non-Residential Units $ 650 per roll

It is important to note that, if you have submitted an assessment appeal and are awaiting a decision, you are still obligated to make your property tax payment by the due date.

If you file a complaint, a hearing will be scheduled and the Notice of Hearing sent to you. Upon hearing the arguments presented, the Assessment Review Board will either lower, raise, or confirm your assessment. The decision will be delivered in writing to all parties concerned.

What's Next

Hearings will be scheduled with the Board and the Parties based on the applicable legislation. The Board Clerk will provide you with an official Notice of Hearing, this notice will be provided to the Complainant (person that filed the complaint), Property Owner and Agent (where applicable). The notice will identify the type of complaint filed (LARB or CARB) and advise you of the date, time and location of your hearing based on the legislation.

Your Notice of Hearing also shows the deadlines for disclosure. The Board will not hear evidence that has not been properly disclosed.

Alberta Municipal Affairs publications are available to assist individuals with the complainant process and understanding how Alberta’s property assessment and taxation system works.

Two guides are available:

Prior to the scheduled hearing date, both Parties to the complaint must submit evidence to each other and the Assessment Review Board in accordance with the legislated guidelines. The timelines for submission are set out in the legislation and are based on which Board will hear the complaint.

There are two types of Assessment Review Boards that hear complaints (appeals) related to Property Assessments:

Local Assessment Review Board (LARB)

Single Family Residential


Disclosure Dates

  • Complainant must provide full disclosure at least 21 days before the scheduled hearing date.
  • Respondent must provide full disclosure at least seven days before the scheduled hearing date.
  • Complainant must provide any rebuttal at least three days before the scheduled hearing date.

Composite Assessment Review Board (CARB)

  • Multi-Family (four units or more)
  • Non-Residential (Commercial) properties

Disclosure Dates

  • Complainant must provide full disclosure at least 42 days before the scheduled hearing date.
  • Respondent must provide full disclosure at least 14 days before the scheduled hearing date.
  • Complainant must provide any rebuttal at least seven days before the scheduled hearing date.

More information about disclosure is available on the Alberta Municipal Affairs website.

When you file a complaint with the Assessment Review Board, you are required to provide evidence in advance of your hearing to support your claim. The Board Clerk can provide information regarding the process to assist you, however they are unable to offer an opinion or advice regarding the merit of your complaint. Your goal is to demonstrate that the assessment on your property is not a fair estimate of the market value of your property in comparison to other similar properties.

Listed below are some ideas to think about when gathering information for your Assessment Review Board hearing:

  • Sales data on properties similar to yours (size, age, location) that sold before July 1 of the previous year.
  • Estimates of your property’s value in the current market from a professional appraiser, assessor or realtor.
  • Repair estimates from a reputable contractor for physical problems (e.g., cracked foundation, roof leaks, etc.). Keep in mind not every defect will lower the value of your property, such as defects that result from normal wear and tear.
  • In presenting comparisons between your property and other similar and/or comparison properties, compare features such as location, lot and building sizes, age, structure type and quality services, basement (finished or unfinished), garage/carports, outbuildings, repairs and environmental problems.
  • Photographs of your property or business and other properties or businesses you are using as comparisons can be useful to establish whether a comparable is similar (inferior or superior). This is especially important if condition or quality is an issue.
  • For apartment condominium units, compare additional features such as the floor your unit is on, view, corner, inside or end unit, floor plan, parking, elevators and building services.
  • In presenting comparisons between your business and other businesses in similar premises; describe the square footage, net rent, location, age, use and quality of the buildings where the businesses are located.
  • Maps are helpful to locate properties used in comparisons.
  • Use a computer spreadsheet program to create your comparison chart or prepare one by hand.
  • You may have witnesses appear on your behalf if you wish.

You will need enough evidence to convince the Board that your assessment is not a fair estimate of the market value of your property. Your assessment should reflect:

  • What your property may have sold for in an open market on July 1 of the previous year (valuation date).
  • The condition of your property on December 31 of the previous year (condition date).

Hearings of the Board are open to the public and documents filed as evidence in respect of a complaint will form part of a public record.

Prior to the hearing date, both the Complainant (the person that filed the complaint) and the Respondent (the Assessor) must submit to each other, and to the ARB Clerk, all evidence and information they wish to use to support their position. Both Complainant and Respondent must submit their evidence and information by the legislated deadlines which is found on your Notice of Hearing. Disclosure includes:

  • Relevant facts that support your complaint
  • Documents you want to use at the hearing (with consecutive page numbers clearly marked on each page)
  • A list of witnesses who will give evidence at the hearing
  • A written summary of oral testimony, including a signed witness report for each witness
  • Any other information or written arguments you intend to rely on

Evidence must be received no later than 11:59 p.m. on the disclosure deadline indicated on the front of the Notice of Hearing (if filing in-person, disclosure documents must be delivered during office hours). If filing by email, disclosure documents should be one pdf file, have consecutive page numbers and have no passwords or other security features enabled.

Failure to comply with the rules governing disclosure due dates may result in your complaint being dismissed.


In-Person Hearings – Will be attended at the Canmore Civic Centre Council Chambers, located at 902 7th Avenue, where oral arguments will be provided.

Written Hearings – if the Parties have elected a written hearing, they will not appear before the Board. Although the hearing date is set the Parties will not be in attendance to the hearing. The decision will strictly be based on the Board’s review of the written submissions received by the Board.

Virtual Hearings –Video Conference – At the time of scheduling the Parties must identify their preference if wishing to attend electronically. The Notice of Hearing will identify the agreed upon platform. The Parties will attend the hearing virtually to provide oral arguments.

Typically, three panel members will hear your complaint. One member will act as the Presiding Officer. You may call the Presiding Officer "Mr. Chair" or "Madam Chair" and the side members by their last names.

The Presiding Officer will start by explaining the hearing process. Usually, the process is as follows:

  • The Board will address any preliminary matters. This includes questions about procedures, disclosure issues, and requests to reschedule.
  • As the Complainant (the person who filed the complaint) you will be asked to present your case first.
  • You may then present your evidence. Be as specific as possible. Explain why you think the assessment is incorrect. Describe the evidence that supports your case. Make your comments to the Presiding Officer, not to other Parties or the other Board members.
  • Then the Respondent (Assessor) may question you and present information in defense of the assessment. You will also have a chance to ask questions of the Respondent.
  • When all the evidence has been presented, you and the Respondent may present final arguments to the Board. This includes a summary of your case and the arguments supporting them.
  • The Board members may ask questions at any time.
  • Remember that you must present enough evidence to convince the Board that your assessment is incorrect or unfair.

The Board will consider the evidence you submitted along with the evidence provided by the Respondent to decide if the current year assessment is fair and equitable compared to other similar properties or similar business premises in the neighbourhood/community.

The Board cannot make decisions concerning your rate of taxation, nor can it help you obtain Municipal services.

You have the option of self-representing, having a family member or friend acting on your behalf, or using a professional tax agent. If there is a fee associated with this service you must complete an Assessment Complaint Agent Authorization Form found on the Municipal Affairs Website (in pdf format) and include it with the complaint.

We recommend that you attend your hearing as your complaint is stronger if you are present. You can question witnesses, answer questions, and respond to arguments or objections made.

If you do not attend the hearing, it will still take place. The Board will review the information you have disclosed (written submissions/evidence).

In exceptional circumstances, the Board may consider rescheduling your hearing. A request to reschedule must be in writing. The request must include the following:

  • Tax roll number
  • Daytime phone numbers and email addresses
  • Detailed reasons why the rescheduling is necessary
  • Hearing dates requested
  • Dates when you are unavailable to attend a hearing
  • Signed consent of the other Parties (if available)

If granted, the Board will schedule a new hearing date. If denied, the hearing will proceed as scheduled.


The Board will issue a written decision 30 days after the hearing has closed.

If you do not agree with the decision of the Board, you have the right to apply to the Court of King's Bench for judicial review of the decision.

Section 470 of the Municipal Government Act governs the review of Board Decisions. Both Parties have the right to apply for judicial review of the decision.


You may withdraw your complaint by completing the Assessment Complaint Withdrawal Form (pdf) in advance of the scheduled hearing.

If there is a change to the assessed value made for any reason by the Assessor, the Assessor will issue a Correction of Assessment form to be signed by the Complainant. The completed form will be forwarded to the Canmore Assessment Review Board and the hearing will be canceled.  A revised Notice of Assessment and Tax Notice will follow.  The ARB Clerk will reach out to confirm the refund of the appeal fee.


A Filing Fee refund will be issued in the following instances:

  • withdrawn complaint at least 2 weeks prior to the scheduled hearing
  • a change in assessed value in favour of the Complainant


The Assessment Review Board is governed by Part 11 of the Municipal Government Act in conjunction with Matters Relating to Assessment Complaints Regulation, 2018.

Failure to comply with legislation and related municipality bylaws may result in your complaint being invalid.
