About Donnell Law Group
Donnell Law Group is a litigation firm based in Keswick, Ontario. Its office at 183 Simcoe Avenue serves York Region and reaches into Southern Ontario, with clients in Newmarket, Richmond Hill, Barrie, Bradford and communities as far as the Kawartha Lakes area. Five lawyers practice at the firm, sharing more than 75 years of combined experience across criminal defence, family law, civil and estate litigation, employment law, municipal law and human rights matters.
Principal Iain T. Donnell was called to the Ontario bar in 1990 and has since built a trial practice centred on criminal, civil and municipal litigation. The rest of the team's bar admissions range from 1986 to 2020, so lawyers at different stages of their careers work side by side on the same files. In family law matters the firm says it tries to resolve issues through negotiation and mediation rather than court action where possible.
