Dropping31

Guelph sits at City Score rank #104 with a standing of 55%, 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. Dropping 31 places versus 2022 (#73 → #104).

Latest owned placements: building permit value rank #30 of 343 (2025); indoor radon rank #77 of 343 at 219 Bq/m³ survey mean; residential mill rate rank #253 of 343 (8.43 mill rate).

Guelph in brief

Guelph still answers to the Royal City, a nickname the municipal history page traces to John Galt naming the 1827 Canada Company town for the British royal Guelph lineage. Galt's plan radiated from a focal point at the Speed River, and that river remains the everyday spine. The Speed River Trail runs through Riverside Park; the Downtown Trail follows the water past John Galt, Goldie Mill, and Joseph Wolfond Park West; the Eramosa River Trail and Silvercreek Trail from Royal City Park fill out the rest of a walking city.

Downtown, Market Square sits between City Hall and the shops on Carden Street, spanning Wilson to Wyndham with an outdoor skating rink that becomes a wading pool in warm months and a glass pavilion for warming up. It is a modern reading of the old Market Place district that once hosted the Provincial Winter Fair, and it still works as the meet-up before a walk along the limestone streets municipal history credits to local quarries.

Campus life is part of the civic self-portrait. The University of Guelph shows up in municipal facts for research such as the Yukon Gold potato, and the Ontario Veterinary College is listed as the oldest school of its kind in the Western hemisphere. Summer calendars add Hot Summer Nights in the parks and Fourth Fridays at the Guelph Civic Museum. Between trail loops, Market Square ice, and a university town rhythm, Guelph feels planned on purpose and still lived along the Speed.

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 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.
