St. Marys in brief

St. Marys is part of the Ontario civic atlas on OpenStats. Long before municipal boundaries, Indigenous nations already knew this valley and its seasons.

St. Marys grew the familiar Canadian way: schools, rinks, churches, and a main street that still anchors weekends. Walk the older blocks and you can still spot seams between eras.

St. Marys service economy ties to county seats, highway corridors, and regional employers that keep main street businesses busy through the year. On OpenStats City Score, St. Marys ranks 97 of 7. Municipal recreation, parks, trails, and utility pages remain the best live guide to how St. Marys 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 St. Marys 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 St. Marys.

Connectivity · OpenStats

OpenStats Broadband Download Speeds

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.

OpenStats Building Permit Value

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.

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). 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.

OpenStats Crime Severity Index

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.

OpenStats Population Growth

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.
