How to appeal your property assessment in Manitoba
In Manitoba, Winnipeg assesses its own properties every two years (the 2027 values use an April 1, 2025 reference date) and the province assesses everywhere else. In Winnipeg you apply to the Board of Revision in a fixed window (June 4–29, 2026 for the 2027 roll, no late applications); elsewhere, at least 15 days before your board sits.

- Applications for revision June 4–29, 2026; first board sitting July 15, 2026.
Tips
- Winnipeg's window is short and fixed. If your 2027 assessment looks high, preview your property's data in the City's preview program before notices are mailed next cycle.
- Lenders don't use your assessment for a refinance; for borrowing, see the equity calculator.
Evidence wins appeals: sales of similar homes near the valuation date, similar homes' assessments, and corrections to the facts on your notice.
