Drinking water first, then permits, tax, internet, radon, and hazards for Ajax.
Ajax sits at City Score rank #227 with a standing of 46%, from 7 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. Rising 38 places versus 2022 (#265 → #227).
Latest owned placements: building permit value rank #343 of 343 (2025); indoor radon rank #132 of 343 at 180 Bq/m³ survey mean; residential mill rate rank #289 of 343 (7.88 mill rate).

Published residential mill-rate context for Ajax.

Where Ajax sits in published building-permit figures for July 2026.
Ajax sits in Ontario. The name traces to HMS Ajax, a Royal Navy cruiser that served in the Second World War.
Ajax grew the familiar Canadian way: schools, rinks, churches, and a main street that still anchors weekends. Ask three locals which decade mattered most and you will get three different answers, all delivered with a grin.
Ajax service economy ties to county seats, highway corridors, and regional employers that keep main street businesses busy through the year. On OpenStats City Score, Ajax ranks 227 of 7. Municipal recreation, parks, trails, and utility pages remain the best live guide to how Ajax 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 Ajax 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 Ajax.

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.
10 editions · 2016–2025
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.
10 editions · 2016–2025
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.
10 editions · 2016–2025
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.
10 editions · 2016–2025
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.
10 editions · 2016–2025
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.
10 editions · 2016–2025
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.
