Customer Review Period – understanding your property value

​​​Step 1: Review your property assessment for accuracy and fairness

Step 2: Talk to an assessor, ask questions and provide new information

Step 3: If we cannot reach an agreement: you can file a complaint (an appeal)

What you need to know

The City issues property assessment notices each year in early January, which begins a 67-day Customer Review Period (CRP) ending on March 10, 2020. During this time, we encourage you to review your assessment details and contact Assessment if you have any questions or comments. We are committed to providing reliable information and service that you can count on.

*If you received an Amended Assessment Notice then your date range will be different. You will still have a 67-day CRP, but it will based on the date of your Amended Notice.

For step-by-step instructions on how to set up your account, check your property details, review sales, you may find it helpful to review the Assessment Search How-to guide for property owners. During Customer Review Period, you can review and update your residential property details under the Property Account tab in Assessment Search. Once there, click on the grey box at the top that says, “Review and Update Your Residential Property Details Here.”

If your property details are accurate, you can review your property assessment by comparing sales of similar properties in the area by using the Sales Search function in Assessment Search.

Step 3: Assessment Review Board: what to do if we can’t reach an agreement

If we are not able to come to a consensus about the assessment of your property, there is a mechanism in place to help reach a conclusion. You may file a complaint with the Assessment Review Board (ARB). The ARB is an impartial tribunal that hears and resolves assessment complaints by property owners. A complaint may be filed no later than the final date noted on the front of the assessment notice.

If you choose to file a complaint, your hearing date will be provided to you by the ARB. It is suggested that you gather and prepare the evidence you wish to provide even before you have been given a hearing date. This is an important task as you will need to provide evidence which supports your determination that your assessment is incorrect.

A valid complaint must be accompanied by the required Filing Fee indicated on the front of the assessment notice. When speaking with us (before making a complaint to ARB) we will provide you with a brief, general summary of the steps you will need to follow to file a complaint with ARB.

You can also visit for more information and/or to file a complaint online. Contact the ARB for a paper copy of the complaint form. Please note, that if you appoint an agent to act on your behalf during the complaint process, you must complete the Assessment Complaints Agent Authorization Form, located on the website under Resources > Forms and Tools.

Have you been asked to send us photos of your property?

In some cases, we may request that you send us photos of your property to review and confirm information that you have shared with us. Please follow these steps for emailing us pictures.

Step 1: If you have been asked to send us pictures to verify information, please take interior photos of every room of the house, including the basement, excluding closets and hallways. Please take a picture immediately inside the front door looking into the house. Ensure that the photos are as wide as possible, show the ceiling-to-floor, and are presented as if we were standing there. Please also send exterior photos of the front and rear of your property.

Step 2: Email pictures to Please include your name, a phone number that you can be reached at, your property address and roll number, along with an explanation of the photos (e.g. pictures show an undeveloped basement).

  • The maximum email size that we have capacity to receive is 15 megabytes. If needed, you can send your photos over multiple emails. In your last email, please note how many emails you sent us in total so that we can contact you if we are missing any.
  • Photos must be attached to the email. We cannot process emails that are saved in a cloud-based storage system.
  • Photos must be in a standard image file format (e.g. jpeg, .tiff, etc.)

Step 3: An assessor will review the photos that you provided. If we determine that an amended notice is needed, then we will provide you with a new value.
