Diana is a proud Board Director of the Circle Community LandTrust, stewarding over 600 family-sized homes across the city. City council once considered selling off these homes, but tenants fought back and they remain in community ownership. Diana is a climate champion on the Circle Board, providing support to staff to pursue improvements to help tenants and lower energy costs. Diana was part of the Sustainability Team at Toronto Community Housing, helping tenants and staff with energy-efficient improvements to their buildings.
As a former Board member of Cecil Community Centre, Diana supported Cecil becoming a surge warming centre to address homelessness in the neighbourhood. With her neighbours, she actively organized in Chinatown to demand affordable housing and support for local businesses.
