About Anderson Foss Professional Corporation

Anderson Foss Professional Corporation is a small law firm in Perth, Ontario, practising from the historic Burchell house at Ten Market Square. Its roots go back to Stewart Hope and O'Donnell, an eastern Ontario firm in the late 19th and early 20th centuries that later became known as O'Donnell Dulmage. James Bond took over Hugh O'Donnell's practice in 1973, and Stephen March joined in 1976, the same year Greg Anderson began articling there. In 1982 the firm bought and renovated the Burchell house, still its home today. After a 1996 reorganization as March Anderson, and Stephen March's appointment to the Ontario Court of Justice in 2000, Greg Anderson practised alone until 2011.

That year, Mary Foss, who had worked at the firm as a legal assistant since 1993, was called to the bar after six years of part time law school, and the practice was renamed Anderson Foss. Mary Foss's daughter, Shannon Foss, had worked at the firm during school and summers since age 17 and joined as a lawyer after being called to the bar in February 2024. Greg Anderson retired from practice on December 31, 2024. The firm's work today centers on real estate, municipal law, wills and estates, and corporate and commercial law for clients in Perth and Lanark County.
