How Greater Sudbury scores

Dropping−34

Greater Sudbury sits at City Score rank #158 with a standing of 51%, from 6 of 8 open-data pillars (tax, construction, connectivity, indoor air, water, seismic hazard, growth, safety). Missing pillars score at median standing so thin coverage cannot inflate the rank. Dropping 34 places versus 2022 (#124 → #158).

Latest owned placements: indoor radon rank #199 of 327 at 94 Bq/m³ survey mean. Full tables and method notes live on each study edition; atlas readings for the same slug open from the topic buttons.

Against the national corpus, Greater Sudbury carries a City Score standing of 51% (rank #158 of 343) with 6 of 8 pillars observed. That sits 2 points below the Ontario peer average across 123 ranked cities. Within Ontario, Greater Sudbury ranks #74 of 123 on City Score.

The strongest signal in the current chart is indoor radon (standing 61%, rank #199 of 327, raw score 94.3). The weakest observed pillar is drinking-water hardness (standing 8%, rank #29 of 343). Crime severity uses the Statistics Canada police-service CSI mapped to Greater Sudbury, Ontario (table 35100026), not a regional proxy.

Drinking-water hardness on the water atlas reads 259 mg/L as CaCO₃ for Greater Sudbury. Compare that figure to the hardness pillar on the chart and to the national hardness guide on the hub.

Greater Sudbury in brief

Greater Sudbury sits in Ontario.

Resource work and regional booms piled new layers on the old town plot. Festivals and street names carry pieces of that plotline into the present.

Agriculture, forestry, tourism, and public-sector jobs still mix on the local tax roll the way many Ontario towns do. On OpenStats City Score, Greater Sudbury ranks 269 of 343. Municipal recreation, parks, trails, and utility pages remain the best live guide to how Greater Sudbury explains itself today.

Permits, mill rates, broadband, radon, hazards, and water quality may show measured values, regional estimates, or empty states until a verified source is linked. That is the same honest pattern OpenStats uses for smaller places already in the corpus, and it keeps Greater Sudbury comparable on the hometown board without inventing numbers. Seasonal recreation programming, winter maintenance, and summer festival calendars still fill the municipal news feed most years. Library branches, arena ice, and aquatics schedules are the practical anchors families check before planning a weekend in Greater Sudbury.

OpenStats Broadband Download Speeds

OpenStats

Cities ranked by household-weighted maximum advertised download (Mbps) from ISED National Broadband Data hex ISP rows, with hex-to-city assignment by population-weighted gravity. The headline 2025 score is the dwelling-weighted mean of per-hex technology ceilings (fibre and cable at 1 Gbps, DSL lower). Household-weighted 50/10 availability (%) is stored on atlas rows as avail_5010_pct. Earlier panel years backcast along a national speed curve with city-specific fiber and availability paths.

OpenStats City Score

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). Crime severity uses StatCan police-service CSI only (Tables 35-10-0026-01 and 35-10-0063-01); cities without a police-service match take median standing on the safety pillar. Growth uses StatCan CSD estimates; construction uses verified municipal building-permit value per resident (population field on each city record, 2021 Census vintage); 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.
