City introduction
Longueuil is the central city of the Agglomération de Longueuil, the urban core of Montréal's South Shore in the Montérégie region. As the agglomeration's central municipality, it delivers shared services — including the municipal court, economic development, land-use and social-housing planning, fire protection, drinking-water production and wastewater treatment, and public transit funding — on behalf of the five linked cities: Boucherville, Brossard, Longueuil, Saint-Bruno-de-Montarville and Saint-Lambert.
The city's history reaches back to the beginnings of New France: the chemin de Chambly, opened in 1665, was an early major road of the colony, and heritage districts in its boroughs rank among the first village cores on this side of the St. Lawrence River. The present city was created on January 1, 2002, when South Shore municipalities were regrouped; a January 2006 reorganization then created the agglomeration, and the boroughs of Greenfield Park, Saint-Hubert and Vieux-Longueuil remained within the central city.

CEER for 2026 is No data because the year is incomplete.
Housing property-tax historical trend
The trend uses one measure only: the increase the City of Longueuil publishes for the average single-detached home's tax bill. Each row is the figure for that year on that one measure. A year with no verified figure on that measure is shown as No data.

Separate note — tax rates, not the trend
This note is separate from the trend above and is not part of it. Quebec tax rates are set per $100 of assessed value, and a rate can move even when the bill increase is small, because the assessment base changes — Quebec reassesses on three-year rolls, so rates and bills routinely move in opposite directions. Rate figures are therefore not used as the trend, are not mixed into the increase chart, and are never converted into bill increases.
The City's budget documents publish a single headline residential property tax rate (taux de taxation) in their tax-evolution tables, applied to the average single-family home's taxable value:
2026: 0.7414
2025: 0.7997
Source: Budget, Ville de Longueuil: https://longueuil.quebec/fr/budget
2022: 0.8959
2019: 0.9097
Source: Budget Longueuil 2025 (budget book, tax evolution table): https://cms.longueuil.quebec/sites/default/files/medias/documents/2024-12/Budget%20Longueuil%202025.pdf
Detailed official rate sheets split the residual residential rate by borough (Greenfield Park, LeMoyne, Saint-Hubert, Vieux-Longueuil) with small sector and debt components; those borough-level components are not merged into the headline budget rate above. These are rates per $100 of assessment as published; a rate change is never converted into a bill increase on this site.
Method
This trend uses one metric only, every year: the increase the City of Longueuil publishes for the average single-detached home's tax bill.
Where a city publishes an increase as components, the components are recorded in the scope notes; a total is used only where the city itself publishes it.
Canada inflation is Statistics Canada, Table 18-10-0005-01, CPI annual average. Canadian dollar Real CEER is Bank of Canada, Valet series CEER_BROADM, total index (1999=100); each value is the annual average of the 12 monthly total Real CEER values (a computed annual average, not a figure the Bank publishes directly as an annual value).
How to read this page
Bars are the Longueuil average single-detached bill increase. Lines are Canada inflation and Canadian dollar Real CEER.
The left axis is a percentage axis shared by the bars and the inflation line. The right axis is a separate index axis for Canadian dollar Real CEER only. CEER is an index and is not a percentage.
A year shown as “No data” has no bar for property tax and no line point for that series, and a missing year breaks a line.
Tax rates per $100 of assessment are separate from the trend and are not charted.
