Canmore Property Assessment: How to Read It and Appeal It

Your Canmore property assessment is the number every tax calculation starts from, and it is almost always a year behind the market. The 2026 assessment is the Town’s estimate of what your property would have sold for on July 1, 2025, in the condition it was in on December 31, 2025. Notices go out in late February, you get 67 days to argue, and after that the value is locked in for the June tax bill. This post explains how the number is produced, how to read the yellow notice and how to complain if it is wrong.

How does Canmore set your property assessment?

Canmore uses the market value standard set out in the Municipal Government Act: the amount a property "might be expected to realize if it is sold on the open market by a willing seller to a willing buyer." The assessor does not appraise your house individually. Mass appraisal groups similar properties and models their value from a minimum of three years of sales, adjusting for lot size, age, quality, view and location. Where sales are thin, an income or cost approach is used instead.

Two dates matter:

• Valuation date, July 1 of the previous year. Compare your 2026 notice with what similar homes sold for in mid-2025, not with the listings you see today.
• Condition date, December 31 of the previous year. A renovation finished in January 2026 will not show up until the 2027 assessment.

The Town re-inspects properties roughly every five years and can ask owners for information; refusing can cost you the right to complain the following year. For 2026, residential assessments rose 12.5% year over year, with the biggest moves in established neighbourhoods near downtown where older homes are increasingly valued for their land and redevelopment potential. Re-inspection in Cougar Creek West and East, Juniper Ridge and the Homesteads also produced adjustments. Hotels and resorts rose about 27%.

What is on the assessment notice?

The yellow notice is not a bill. Check five things:

Factual errors in the description or the owner’s name and mailing address can be corrected by emailing taxes@canmore.ca without filing a complaint.

How do I complain about my Canmore assessment?

1. 1Review within the customer review periodAsk: is the value a fair estimate as of last July 1, are the recorded details correct, is it equitable against neighbours, and is the code right.
2. 2Talk to the assessor first (free)Submit an inquiry through the Town’s online form or call the assessor. Under the Municipal Government Act you can request the comparable sales and detailed information used for your property.
3. 3File before the complaint due dateComplete the Assessment Review Board complaint form, upload it through the Town’s submissions portal and pay the fee in person by 4:30 p.m., or by credit card by phone by noon on the due date (May 5 in 2026).
4. 4Prepare evidenceComparable sales around the valuation date, photos of condition issues, an appraisal if you have one. Complaints about the tax rate or the amount of tax are not valid grounds.
5. 5Hearing and decisionThe Local Assessment Review Board hears residential complaints of three or fewer units (May–June in 2026); the Composite board handles larger and non-residential property (July). Win and the fee is refunded and taxes recalculated.

Complaints filed without the fee, or after the deadline, are deemed invalid and may be dismissed. The board is independent of Town administration and is governed by Part 11 of the Municipal Government Act and the Matters Relating to Assessment Complaints Regulation. Judicial review at the Court of King’s Bench is the only step beyond it.

What does the assessment mean when you are buying?

The assessed value on a listing is a lagging indicator, not a valuation. In a rising market the assessment sits below sale prices, in April 2026 the Town noted median assessed values of about $1.48 million for a single-detached home and $800,000 for a condo, and CBC reported that sale prices typically run well above assessments. For what a property would actually sell for, start from a home evaluation built on recent sales. Use the assessment for three things instead:

• Estimating the tax bill, assessed value × 2026 rate, in the property tax calculator.
• Confirming the class. The assessment code tells you whether the home is taxed as a tourist home, which affects both the bill and whether nightly rental is legal.
• Spotting mismatches. A listing that says 2,400 sq ft when the assessment record says 1,900 is a question worth asking before you pay for an inspection.

After you buy, remember that the December 31 primary-residence declaration is also the gate to the complaint process: no declaration, no right to complain about that year’s assessment (Town of Canmore, Livability Tax Program).

What this means if you’re buying

Treat the assessment as a tax input and a data check, not as a price guide, and remember that the value on a 2026 notice describes the July 2025 market. Once you own, put two dates in the calendar: late February, when the yellow notice arrives and the 67-day clock starts, and December 31, when the primary-residence declaration keeps both your tax rate and your right to complain intact. If the number looks wrong, start with a phone call to the assessor. It costs nothing and settles most disputes before a $50 fee and a hearing are needed. The rest of the buying guide covers what happens between offer and possession.
