A passionate volunteer, activist, and elected representative for environmental issues for most of her adult life, Mary-Margaret learned about environmental issues through engaging with the local environmental movements in Toronto and working with other environmental leaders. A two-term Toronto City Councillor from 2010 to 2018, she was a champion for the development and implementation of TransformTO, Toronto’s first Climate Change Adaptation and Mitigation Plan, removal of the Gardiner Expressway, and planning changes to increase housing options in already built-up areas of the city, like Laneway Suites. She has a long history of community involvement, including co-founding a Farmers’ Market and Community Association and advocacy for cycling infrastructure and a pesticides ban in Toronto.
