About Maclaren Corlett LLP

Maclaren Corlett LLP is a business law firm founded in 1873 as Scott & Stewart. It is based in Ottawa with a longtime office in Toronto, and the firm's own history page describes it as having stayed moderate in size by choice while building an international reputation. The practice today covers business and corporate law, advertising and marketing law, employment law, real estate, wills, trusts and estate planning, and workplace investigations, along with agency work before the Supreme Court of Canada.

That Supreme Court agency work is one of the more distinctive parts of the practice: lawyers at the firm act as Ottawa agents for provincial and municipal governments, other law firms, and private and public organizations from across Canada, handling matters that range from procedural questions to the oral argument of appeals. The Toronto office, at 2 Bloor Street East, is where Mary G. Griffith practices a regulatory, advertising, and marketing law practice covering products from cosmetics to pharmaceuticals; Griffith has been recognized in Best Lawyers in Canada since 2006. Managing Partner Gordon B. Greenwood works in the same regulatory and advertising field alongside corporate and commercial law, and is a registered trademark agent and lobbyist.
