4 lawyers · Established 1998 · United Counties of Stormont, Dundas and Glengarry
One of 15 law firms listed in Cornwall, and one of 8 handling Business & Corporate Law.
McDonald, Duncan, Doré LLP is a full-service law firm in Cornwall, Ontario, founded in 1998 by John McDonald and Bill Duncan. Both had already spent more than 20 years practising law in the Cornwall area with other partnerships before starting their own firm, which grew into one of the largest law firms in Cornwall and the surrounding area. Valérie Doré, who grew up in Cornwall, later joined as a named partner, and Chelsey Cook, a Cornwall native who studied law at Bond University in Australia, returned to the firm in 2021 and became a partner in 2022.
The firm's four lawyers concentrate on specific areas of law, including business and corporate matters, real estate, wills and estate planning, family law, civil litigation, and administrative law. That specialization is meant to let files move efficiently while still keeping the range of a full-service practice under one roof. Services are offered in both English and French, reflecting Cornwall's bilingual community and Doré's own background in the city's francophone community.
