The short answer
In Mirabel, the city announces a 2.9% increase in the residential tax bill for 2026, without publishing an average bill in dollars. The residential general property tax rate is $0.267 per $100 of assessment ($0.33 in 2025). 2026 is the first year of a new assessment roll: values went up, the rate was adjusted, and it is the bill, not the rate, that tells you what you pay.
The 2026 tax bill in Mirabel
The city does not publish an average bill in dollars. The City announces an increase of $53 (2.89%) in the property tax bill for the average single-family home, without giving the total bill amount.
Increase announced by the city for 2026: +2.9%. Each city measures its increase its own way (with or without water, waste collection or special taxes): compare the bills, not just the percentages.
Average value of a home on the assessment roll, according to the city: $595,686. For reference, a house sold for $650,000 at the 2026 median on Centris (447 sales): the municipal assessment and the sale price are two different things.
The property tax rate in Mirabel
| Rate per $100 of assessment | 2026 | 2025 | Rate change |
|---|---|---|---|
| General property tax, base residential rate | $0.267 | $0.33 | -19.1% |
Other rates: In 2026, Mirabel created residential subcategories: reference residual $0.275 (legal base rate), 1 to 2 dwellings $0.267, 3 to 5 dwellings $0.285, 6 to 9 dwellings $0.328, 10 to 49 dwellings $0.341, 50 dwellings or more $0.352. The special debt property tax is added: $0.050 for 1 to 2 dwellings ($0.052 reference, $0.054 for 3 to 5 dwellings). The City presents a total of $0.317 for 1 to 2 dwellings. In 2025: residual base rate $0.330 plus debt $0.064. Special sector taxes under loan by-laws.
Fixed fees: Water fee of $292 per dwelling unit served by the water supply system in 2026 ($275 in 2025). No separate waste collection fee found in By-law 2686.
Careful with the lower rate. The rate drops 19.1% because the new roll raised assessments: the city adjusts the rate to collect its revenue. A lower rate after a new roll is not a tax cut.
The assessment roll in Mirabel
New property roll in effect in 2026 (the City refers to the “début d'un nouveau rôle” (start of a new roll); the cycle years are not specified in the documents read).
Calculating the taxes on a house in Mirabel
The general property tax is calculated as: municipal assessment × rate ÷ 100. Example: a house assessed at $500,000 would pay $1,335 in general property tax at the 2026 rate of $0.267. This is a sample calculation, not the actual bill: add the fees (water, waste collection), special taxes and, where applicable, sector taxes. The actual bill for an address is on the city's online assessment roll and on the seller's latest tax bill: ask for it before making an offer.
The 2026-2027 school tax
The school tax is not set by the city. Since 2020-2021, the rate is the same everywhere in Quebec: $0.07899 per $100 of standardized assessment for 2026-2027 ($0.08423 in 2025-2026), and the first $25,000 of value is exempt. It is calculated on the standardized value, which can differ from the roll value. Example: for a standardized value of $595,686, the 2026-2027 school tax would be about $451.
Before buying in Mirabel
- Ask for the seller's latest tax bill and the roll assessment of the address: it is the only exact figure for your budget.
- Check the roll year. After a new roll, the assessment can jump: next year's bill will not be this year's.
- Count the sector fees (water, sewers, garbage, local improvement taxes): two houses of the same value in the same city can pay different amounts.
- Include taxes in the mortgage calculation. The lender includes them in your debt ratios: the welcome tax is paid once, property taxes every year.
