About Desmarais, Keenan LLP

Desmarais, Keenan LLP is a full service law firm based in the old CBC building on MacKenzie Street in downtown Sudbury, Ontario. The firm has practiced there since 1922, making it one of the oldest law firms in Northern Ontario, and it's fully bilingual, offering its services in both English and French. Its lawyers handle real estate, corporate and commercial law, family and divorce law, wills, estates and trusts, insolvency and bankruptcy, municipal law, and litigation, serving individuals and businesses across Greater Sudbury and Northeastern Ontario.

The firm's corporate and commercial group has acted for First Nations organizations and economic development corporations alongside chartered banks and credit unions, and its municipal law lawyers regularly advise municipalities, hydro commissions, and school boards across Northeastern Ontario. The real estate group also acts for farm credit institutions on financing and debt matters. Desmarais Keenan takes on articling students each year, and the firm says many have gone on to careers in law and with government agencies. One of its associates, a retired Deputy Small Claims Court judge, was called to the bar after earning a law degree from Osgoode Hall in 1960.
