Research consistently links physical activity to improved mental health outcomes — reduced rates of depression and anxiety, better sleep, greater resilience to stress. Active transportation — getting around by walking, cycling, or a combination with transit — is a way of integrating physical activity into daily life without requiring dedicated gym time. How cities are designed determines how much of this kind of activity is possible for ordinary residents going about their ordinary routines.
In Toronto, the design of many suburban neighbourhoods makes walking and cycling impractical for everyday purposes. Wide arterial roads without sidewalks, strip malls surrounded by parking, and residential subdivisions without destinations within walking distance are common features of parts of the city that were developed primarily for car access. In these environments, physical activity requires a deliberate decision to go to a park or gym — it does not happen as a byproduct of daily movement.
The Commute and Stress
The mental health toll of long car commutes has been studied extensively. Commuting by car in heavy traffic is one of the most consistently stressful elements of daily life in urban regions, and its effects accumulate over time. Long commutes have been associated with elevated stress hormones, poorer sleep quality, reduced time for social connection and leisure, and lower overall life satisfaction.
Active commutes — particularly cycling — show a different profile. Research comparing commute experiences across modes has found that cycling commuters report higher satisfaction with their journey than car commuters, even controlling for commute length. The combination of physical activity, fresh air, and the absence of traffic frustration appears to make cycling a more psychologically beneficial way to start and end a workday. Walking commutes show similar benefits when the route is pleasant and the distance is manageable.
Green Space and Urban Design
The mental health benefits of active transportation are amplified when the environment is pleasant to move through. Routes that pass through parks, tree-lined streets, and neighbourhoods with interesting ground-level activity are more enjoyable — and more likely to be chosen — than routes through industrial areas or along loud, exhaust-heavy arterial roads. This is one reason why cycling infrastructure that is pleasant and visually appealing tends to attract more riders than infrastructure that is technically safe but aesthetically hostile.
Toronto's ravine system represents an underutilised asset in this regard. The network of trails through ravines and valleys provides genuinely pleasant active transportation routes through the city — but the connections between these trails and the broader cycling and pedestrian network are incomplete, limiting their usefulness as everyday commute routes rather than recreational destinations.
Social Connection Through Active Transportation
Walkable and cycling-friendly environments tend to support more casual social interaction than car-dependent ones. When people are outside on foot or by bike, they are more likely to encounter neighbours, stop to talk, and develop the informal connections that contribute to community cohesion. These kinds of low-stakes social interactions are associated with greater sense of belonging and wellbeing in urban populations.
In contrast, car-oriented design moves people through space in enclosed, private vehicles, reducing incidental contact with the broader community. Designing streets and neighbourhoods that encourage people to be outside — through comfortable sidewalks, interesting destinations within walking distance, and safe cycling routes — is a form of public health investment that goes beyond the physical.
Access Across Income Levels
The mental health benefits of active transportation are not equally distributed across the city. Higher-income neighbourhoods tend to have more street trees, better pedestrian infrastructure, and more pleasant cycling routes than lower-income ones. This means that the residents who may face the greatest mental health pressures — related to financial stress, precarious work, and housing insecurity — are also the residents least likely to live in environments that make active transportation easy and enjoyable. Equity in transportation infrastructure is, in part, an equity in health issue.
