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.
Wheelchair accessibleDonnelly Law's office is on Carlaw Avenue in Toronto's Leslieville area, in a complex built in 1907 for the Phillips Manufacturing Company and designed by architect Edward J. Lennox, who also designed Old City Hall. Reliable Toys later occupied much of the same complex through the mid twentieth century. Like many of the former factories along Carlaw, the building has since been converted into commercial and live work space rather than torn down.
The setting fits a practice built around land use and heritage. Carlaw grew into a manufacturing corridor by the 1920s, when the area hosted gum, soap, paint and varnish, brickyard, coal, and paper box businesses, more than a hundred factories in all. Many of those buildings have since been adapted for offices, lofts and studios instead of demolished, a pattern of preservation over replacement not unlike the heritage and greenspace disputes the firm takes on elsewhere in Ontario.
