Varley Art Gallery programming and One Love Festival listings put Main Street Unionville on the culture map, not only Markham Centre.
Where Markham sits in published building-permit figures for July 2026.
Markham's summer calendar has a new centre of gravity: Markham Centre, where the City is planting the Ontario Honda Dealers Indy for a multi-year run starting in August 2026. Launch parties, volunteer calls, and an I'm in for Indy contest aimed at Markham residents all point to the same civic core rather than a borrowed downtown elsewhere. York Region news packaging still wraps Markham inside upper-tier politics, and Highway 7 improvement notices remind drivers that the corridor is part of everyday commute talk.
Culture has its own map. The Varley Art Gallery of Markham sits on Main Street Unionville and hosts gatherings such as One Love Festival. Markham Museum on Markham Road keeps the outdoor heritage campus busy with Night at the Museum evenings and AppleFest. Flato Markham Theatre and Heintzman House round out the City arts roster, while Aaniin Community Centre puts fitness nights on the East Piazza and library programming under the same Aaniin name. Markham Public Library stays in the newsroom when leadership changes, which is how municipal institutions signal they matter.
Council stories on the Markham desk lean hard into housing: rental incentives, short-term rental votes, and development committee streams that keep planners on the live agenda. Election paperwork for 2026 is already open on markham.ca for candidates who want in. On the OpenStats City Score for 2026, Markham sits at rank 11 of 125. Rankings aside, the hometown read is a Markham Centre race weekend, Unionville gallery nights, and a museum campus that still hosts apple season.

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.

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.
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.
