The short answer
In Rosemère, the city announces a 2026 tax bill of $3,751 for its reference property. The city's figures are partial on this point: check the actual tax bill for the address.
The 2026 tax bill in Rosemère
$3,751: this is the 2026 tax bill published by the city. What the city means by it: 2026 tax bill for the average house of $753,900: $3,751, versus $3,572 in 2025 (tax shift +$36, general tax +$71, special infrastructure tax +$54, public transit +$18).
Average value of a home on the assessment roll, according to the city: $753,900. For reference, a house sold for $845,000 at the 2026 median on Centris (106 sales): the municipal assessment and the sale price are two different things.

Calculating the taxes on a house in Rosemère
The general property tax is calculated as: municipal assessment × rate ÷ 100. 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 $753,900, the 2026-2027 school tax would be about $576.
Before buying in Rosemère
- 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.
