The Impact of Urban Green Space Accessibility on High School Students' Mental Health in Toronto

Within the vibrant urban fabric of Toronto, Ontario, the dearth of green spaces presents a significant contributing factor to numerous mental health challenges faced by students within the Toronto District School Board. This study delves into the intricate relationship between green spaces and mental health outcomes within Toronto's diverse wards. Building upon prior research, our investigation evaluates the Green Space Index (GSI) and Urban Development (UD) metrics across the city's 22 wards, aiming to elucidate the interplay among these variables. Using data from the 2021 Toronto District School Board (TDSB) Winter Check-in survey and established environmental indices, we explore how accessibility and distribution of green spaces correlate with high school students' mental well-being, specifically feelings of happiness. Contrary to prevailing assumptions, our findings do not substantiate a statistically significant relationship between GSI, UD, and mental health metrics. Multiple regression analysis underscores the limited predictive power of these variables, even when considering income levels, while the Pearson correlation matrix reveals weak associations among studied variables. Our research highlights the complexity of factors influencing mental well-being and emphasizes the need for holistic approaches to urban planning that integrate socio-environmental considerations. Yet, further research is warranted to deepen understanding of environmental influences on mental health and inform strategies for fostering resilient, inclusive urban communities.
