Achievements
Published residential mill-rate context for Longueuil.
Borough with its own arrondissement council rhythm. It is the historic name Longueuillois still use when they mean the older urban core.
English place-name borough retained on municipal council listings. The bilingual street feel is part of Longueuil's everyday map.
RTL is the branded transit network for the Longueuil agglomeration.
Where Longueuil sits in published building-permit figures for July 2026.
Longueuil is one city that still sounds like three when council night arrives. Vieux-Longueuil, Saint-Hubert, and Greenfield Park keep separate arrondissement sessions on the municipal calendar, and Longueuillois navigate that map without translating it into Montreal borough slang. Service requests go to 311 or Mon portail citoyen; the civic address on Chemin de la Savane is the quiet institutional landmark behind those tools. Agglomération de Longueuil is the wider frame when the conversation leaves city limits.
Transit talk names the RTL, the Réseau de transport de l'agglomération de Longueuil, and the OPUS card that rides with it. That is South Shore vocabulary, not STM métro gossip, and locals correct outsiders who blur the two. On the economy page, city hall leans hard into a pôle aérospatial story, the kind of investment headline that makes Longueuil sound like a hangar town as much as a residential one. Greening work partners with Soverdi for a long tree-planting target, so the environmental file has a named ally instead of a vague pledge. Info-travaux and collectes sit in the same quick-link row as aerospace announcements, which is how Longueuil sounds: hangars in one headline, recycling day in the next.
On the OpenStats City Score for 2026, Longueuil sits at rank 88 of 125. The hometown read is agglomeration geography: borough pride first, RTL buses second, and an aerospace pitch that keeps industrial identity on the front page beside the pool schedule. Greenfield Park's English place name on French council agendas is part of that texture.

City Score from 2016–2025 across eight open-data pillars. Individual study placements are listed in the panels below.
Each study below is its own ranking. Where a study has more than one edition for this city, the chart shows standing across those years only.
Connectivity · OpenStats
OpenStats
Cities ranked by estimated best advertised download (Mbps). Anchored to the current ISED National Broadband Data vintage, then backcast along a national speed curve with city-specific fiber-arrival and 50/10 availability paths so relative ranks can change over the decade. Not a claim of audited historical hex maps for every year.
10 editions · 2016–2025
Construction · OpenStats
OpenStats
Cities ranked by calendar-year building permit value. Direct rows sum Statistics Canada Table 34-10-0292-01. Cities without a direct reading use population × provincial per-capita permit intensity (estimated), so every seed city has a year-varying construction signal.
10 editions · 2016–2025
Composite · OpenStats
OpenStats
Dimensional average of OpenStats open-data pillars for each panel year 2016–2025: tax, construction, connectivity, indoor air, water, seismic hazard, population growth, and crime severity. Each series is scored 0–1 within its edition; series in the same pillar are averaged, then all eight pillars are averaged with equal weight. Missing pillars score at median standing (0.5). Growth and CSI use StatCan annual tables; permits, mill rates, and broadband use live rows plus documented year-varying estimates where needed. Radon, water, and PGA may be survey/model vintages carried forward and are flagged when static for more than two years. External commercial livability lists are never inputs.

Safety · OpenStats
OpenStats
Communities ranked by Statistics Canada Crime Severity Index (Table 35-10-0026-01). Rank 1 is highest CSI (worse). Values are CMA where a metro match exists, otherwise provincial CSI. Hometown pages label the grain.

Water · OpenStats
OpenStats
Communities ranked by municipal drinking-water hardness (mg/L as CaCO₃). Hardness changes slowly; the atlas vintage is carried across panel years and flagged when static for more than two years.

Water · OpenStats
OpenStats
Communities ranked by reported lead (µg/L) on the OpenStats water atlas. Carried across panel years until annual municipal report panels are ingested.

Health · OpenStats
OpenStats
Communities ranked by Health Canada survey mean indoor radon (Bq/m³). Rank 1 is the highest mean. Decade panel years without a new survey carry the CMA survey vintage forward; they are not annual retests.

Growth · OpenStats
OpenStats
Cities ranked by year-over-year population growth from Statistics Canada annual CSD estimates (Table 17-10-0155-01). Rank 1 is fastest growth. A few places without a clean CSD match use a provincial-path estimate anchored to seed population.

Property tax · OpenStats
OpenStats
Municipalities ranked by residential mill rate. Rank 1 is the highest rate. Published municipal years are used when available; gaps are interpolated or follow the provincial median path so the tax pillar moves year to year for every city.
