Walkability is not simply the presence of sidewalks or a number displayed beside a listing.
What the research tells us
Canadian research has found that neighbourhood walkability is positively associated with transportation-related physical activity among adults. A Statistics Canada study linking the Canadian Active Living Environments database with national health surveys found that walkability was associated more consistently with transportation-based activity than with recreational activity. The findings also differed by age, demonstrating that the same built environment may not affect children, adults and older residents in identical ways.
An Ontario study following almost 959,000 adults found that people younger than 65 living in highly walkable neighbourhoods had a lower ten-year incidence of diabetes than comparable adults in low-walkability areas. The study was observational, so it supports an association rather than proving that neighbourhood design alone caused the difference.
A broader systematic review of walkability and health outcomes found strong longitudinal evidence connecting walkability with obesity, type 2 diabetes and hypertension outcomes in the expected direction. Again, these findings describe population-level relationships, not guaranteed outcomes for every individual.
Public data you can check
Statistics Canada’s Canadian Active Living Environments 2.0 dataset, or Can-ALE 2.0, provides standardized information about how supportive neighbourhood built environments may be for active transportation. It was calculated for dissemination areas across Canada and is intended to support research into relationships between neighbourhood form, physical activity and health.
Statistics Canada’s Proximity Measures Database provides ten measures and a composite indicator representing neighbourhood-level access to services and amenities. Values are normalized from 0 to 1, with higher values indicating greater relative proximity.
Its newer Spatial Access Measures evaluate potential access to amenities using different modes of transportation. This is helpful because an amenity may be accessible by car but difficult to reach on foot, by bicycle or by transit.
Toronto also publishes a pedestrian network based partly on the City’s sidewalk inventory, although the corresponding Open Data entry is currently marked as retired. It may still be useful historically, but readers should verify whether a newer City tool or replacement dataset is available before relying on it.
What to observe in person
Choose five destinations you would regularly use, such as:
- A grocery store
- A transit stop
- A pharmacy
- A park
- A school, childcare facility or café
Walk the actual routes from the property. Notice:
- Whether the sidewalks continue for the full route
- The number and difficulty of road crossings
- Vehicle speeds
- Lighting and visibility
- Shade and weather protection
- Hills and steep grades
- Snow-storage areas
- Construction obstructions
- Benches and resting places
- Accessibility for strollers, wheelchairs, mobility devices or grocery carts
A grocery store may appear six minutes away on a map but require crossing a wide arterial road or walking through a large surface parking lot.
