Mid-sized cities like London, Ontario, are increasingly facing the challenges posed by climate change, including extreme weather events, intensified urban heat islands, and devastating flooding risks. In response to these pressing issues, the City of London declared a climate emergency in 2019, emphasizing an urgent need to reduce greenhouse gas emissions and enhance the city's resilience. Green roofs emerge as a vital solution in this context supported by research to offer benefits such reducing greenhouse gas emissions. Despite the benefits associated with green roofs, the adoption of green roofs in London remains relatively low, and limited research has yet to uncover these issues. This study employs in-depth interviews and thematic analysis to explore the perceptions of key stakeholders, including municipal staff, green roof practitioners, developers, and non-governmental organizations (NGOs), on the implementation of green roofs in the city. The research findings indicate that certain stakeholders recognize the significant benefits of green roofs, particularly in reducing occupational hazards in their facilities. Additionally, some perceive that green roofs provide therapeutic effects for individuals viewing them from windows in close proximity to hospitals or Condos. However, some actors are of the view that the implementation of supportive policies (i.e by-laws), together with creating awareness for community members as well as incentivizing potential adopters promotes the widespread implementation of green roofs in the City. The study concludes that integrating the stakeholders' recommendations into urban planning in the City of London can ensure progress towards a more resilient and sustainable environment. These findings hold significant implications for scholars and urban planning policies on a local scale.
