Overview

The links between climate change and mental health and well-being are complex and interconnected.

These two papers, produced for Thrive Toronto, explore these links. They were produced to help inform Thrive Toronto’s future climate-focused work.

Understanding the Impacts of Climate Change on Mental Health articulates the links between mental health, well-being and climate change, with a holistic perspective on how climate resilience is intimately linked with social determinants of mental health. This paper was written by Swelen Andari, Director, Strategy, Climate Resilience & Youth Mental Health, at the Centre for Addiction and Mental Health (CAMH), on behalf of Thrive Toronto.

The Unequal Mental Health Impacts of Climate Change in the GTA explores how climate change disproportionately affects the mental health of marginalized communities in the Greater Toronto Area. It examines the role of structural inequities, such as housing, income and exclusion from planning, in shaping vulnerability to climate-related stressors like heat and flooding. This paper was written by Mauriene Tolentino, Researcher, at Wellesley Institute, on behalf of Thrive Toronto.

This Climate and Mental Well-Being Series also includes a Glossary of Terms to support accessibility and understanding of key concepts. 

Key messages

  • Climate change presents significant threats to human health, driving increasingly severe impacts on physical health, mental health and psychosocial well-being, both in Canada and around the world.
  • Those already facing social and structural inequities are at greatest risk, shouldering a disproportionate share of climate-related mental health and psychosocial burdens. In Toronto, existing disparities further amplify these vulnerabilities, compounding the mental health challenges linked to climate change.
  • Climate change threatens mental health through multiple, interconnected pathways, from direct trauma caused by extreme weather events, to indirect harm via worsening socioeconomic, environmental and political conditions, as well as the psychological toll of living with the persistent threat and uncertainty of a changing climate.
  • Addressing climate risks through the social determinants of mental health strengthens both climate resilience and health equity. Community-led initiatives in areas like green infrastructure, food security and emergency preparedness have potential mental health, social equity and mitigation co-benefits, such as improved air quality, reduced emissions, increased affordability and stronger social cohesion.
