About Donnelly Law

Donnelly Law is a solo environmental and land use planning practice based in Toronto. David Donnelly founded the firm in 2008 to represent environmental non-profit and charitable organizations, citizen groups and First Nations, and the firm has served as counsel to Environmental Defence since 2000. Its work spans environmental law, land use planning, First Nations consultation and accommodation, and policy reform, along with compliance and enforcement matters, drafting, and lobbying on proposed legislation.

Donnelly holds an Honours B.A. from the University of Toronto (1987), a Master of Environmental Studies from York University (1994), and an LL.B. from the University of Windsor (1999), and has been a member of the Law Society of Ontario since 2002. Before founding the firm, Donnelly was executive director of Environmental Defence Canada from 1988 to 1996 and later practiced at a Toronto litigation firm based in the city's historic Gooderham "Flatiron" Building. Matters handled by the firm have included the Oak Ridges Moraine hearings in Richmond Hill, the Big Bay Point marina hearing on Lake Simcoe, and consultation work for the Huron-Wendat Nation on archaeological sites tied to the Seaton lands in Pickering.
