Sarnia sits at City Score rank #126 with a standing of 53%, 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 71 places versus 2022 (#55 → #126).
Latest owned placements: indoor radon rank #189 of 327 at 95 Bq/m³ survey mean; residential mill rate rank #12 of 57 (16.67 mill rate). Full tables and method notes live on each study edition; atlas readings for the same slug open from the topic buttons.

Published residential mill-rate context for Sarnia.
North-end Lake Huron park with beach, Children's Animal Farm, and long-running community events. City staff call it the centrepiece
Twin spans over the St. Clair River toward Port Huron, with Point Edward at the Canadian footing. Lambton museum pages treat it
Canatara Park covers about 174 acres on the Lake Huron shore and hosts Canada Day and Christmas on the Farm.

Sarnia sits in Southwestern Ontario where Lake Huron empties into the St. Clair River at the Canada-US border. Municipal economic pages lead with that geography, then talk multi-modal corridors and a cultural district that shares the map with industry. Locals still hear Chemical Valley in everyday shorthand, while Observer headlines keep Line 5 and Sarnia-Lambton files on the front burner. Point Edward holds the Blue Water Bridge footings next door, and the twin spans remain the postcard backdrop from the water. Lambton museum pages treat the bridge as the place to watch freighters and eat fries with both countries in view.
Canatara Park is the parks-system centrepiece: a 174-acre north-end stretch on Lake Huron with Canatara Park Beach, the Children's Animal Farm, Canada Day, and Christmas on the Farm. City releases note Blue Flag status for the beach and a live master-plan conversation about future investment. Down at Sarnia Bay, the Andrew S. Brandt Marina lines up more than 350 slips with views of the Blue Water Bridges. Christina Street carries City Hall and the invest-Sarnia desk.
The calendar mixes border-city work with local play. Captain Kidd Days still marks the summer run on the Observer front, and Lambton College shows up whenever research and new programs make news. Bio-based manufacturing and research sit in the municipal growth pitch beside the older industrial story. Trail alerts on the Suncor Energy Foundation Nature Way remind people that conservation work and plant geography share the same shoreline. On OpenStats City Score for 2025, Sarnia sits at rank 313 of 343. People who live here still introduce the place by the lake-to-river turn and the bridges before they argue about plants or pipelines.

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.
Safety · OpenStats
Statistics Canada does not publish a police-service Crime Severity Index that OpenStats can match to Sarnia without copying a province, CMA, or another city. The safety pillar scores at median standing (50%) on City Score, the same rule used for other missing pillars.
Connectivity · OpenStats
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.

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). 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.

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 (education levies are shown on property-tax pages but not added here). Rank 1 is the highest rate. Atlas seed and published municipal rows anchor the panel; off-panel tax years (e.g. 2026) carry across 2016–2025; remaining gaps follow provincial paths.

Hazards · OpenStats
OpenStats
Communities ranked by NRCan peak ground acceleration (higher = stronger shaking hazard). Rank 1 is highest PGA. The seismic model is multi-year; values are carried across the City Score panel and flagged as static until NRCan publishes a new generation.
