1. Read your notice
Assessment notices are mailed in early March (to be confirmed for 2027). The notice shows your assessed value, the property’s details as City of Grande Prairie has them, and the last date to file a complaint. The complaint deadline is printed on your notice (2 April in 2025).
2. Check the facts first
Most errors are in the details: floor area, year built, a garage or basement that isn’t there, a lot size. Compare what the notice says with your home. Then compare your value and its change with similar homes nearby; the free check does that from City of Grande Prairie’s own data.
3. Talk to the assessment office
During the review period you can call or write to City of Grande Prairie’s assessment office and ask how your assessment was prepared. Many questions are settled at this step, and there is no fee.
4. File a complaint, if you still disagree
A formal complaint goes to the Assessment Review Board on the form City of Grande Prairie provides, by the deadline on your notice, with the fee: see the City's fee bylaw. A complaint is about the assessed value or the property’s details, not the tax rate. Late complaints are generally not accepted.
What evidence helps
- Corrections to the property’s details, with proof (plans, photos, a building permit).
- Similar homes nearby with lower assessments, or with smaller changes, each identified by address and roll number so the Board can check them.
- Recent sales of similar homes close to the valuation date (1 July of the year before the notice).
The evidence pack lists similar homes with the municipality’s own figures. It does not fill in forms or speak for you at a hearing.
