About Arnold Foster LLP

Arnold Foster LLP is a small law firm in Georgetown, Ontario, part of the town of Halton Hills. The firm traces to 1999, when the law practices of Herbert T. Arnold and Steven C. Foster merged to form Arnold, Foster. It now has four lawyers and six support staff working from the Guelphview Plaza on Guelph St, and its practice covers real estate, estates and succession planning, business law, family law, civil litigation, and land development.

Herbert (Bert) Arnold, a founding partner, studied at the University of Toronto, was called to the bar in 1977, and has built a practice around real estate development, appearing frequently before Ontario's Local Planning Appeal Tribunal. Steven C. Foster, the other founding partner, studied at Osgoode Hall, was called in 1986, and focuses on family and civil litigation along with real estate and estate planning. Thomas M. Arnold joined the firm as an articling student in 2005, fresh out of Dalhousie Law School, and became a partner in 2008. Fiona A. Japaul, who studied law at the University of Leicester in England and holds a B.A. from York University, joined in June 2025 to practice family law, real estate, and estate planning.
