Bill Henderson is a Toronto sole practitioner who has run what the firm's own site calls a "virtual law office" since January 1, 1996, after leaving the firm Lang Michener. Henderson grew up in Niagara Falls, Ontario, earned a law degree from the University of Ottawa in 1980, and moved to Toronto afterward, completing an articling year and the Ontario Bar Admission Course in 1981 and 1982. Before entering private practice, Henderson worked for the federal Department of Indian and Northern Affairs and then as a contract consultant while attending law school, and has advised First Nations and Aboriginal associations since 1982.
The practice centres on Aboriginal, treaty, and constitutional law. Henderson has acted as counsel or intervener in several cases, including Ontario (Attorney General) v. Bear Island Foundation before the Ontario Court of Appeal and the Supreme Court of Canada, and helped formulate interventions for Ontario Aboriginal associations in the Supreme Court cases Guerin v. The Queen and R. v. Sparrow. From 1991 to 1993, Henderson served as general counsel to the Indian Specific Claims Commission of Canada. Henderson also wrote several entries, including "Indian Act" and "Aboriginal Rights," for the first edition of The Canadian Encyclopedia, and has published articles in the Ottawa Law Review and the Law Society of Upper Canada Gazette.
The office sits on Bloor Street East, in the stretch the firm's own site describes as running from the Hudson's Bay Centre at Yonge and Bloor east toward Parliament Street, an area it characterizes as financial institutions, apartment buildings, and mixed retail; the same page notes that farther east, at Park Road, the land drops into the Rosedale Valley ravine. Bloor Street takes its name from Joseph Bloor, who developed the area in the 19th century, according to the same page.
Henderson has written that operating as a sole practitioner made a big difference in overhead expense.
