About Goldmans LLP

Goldmans LLP is a small commercial litigation firm based in Toronto's financial district at 18 King Street East. The firm was previously known as Goldman Hine LLP. Some of its own practice area pages online still carry that earlier name, a leftover from the rebrand to Goldmans LLP. Managing partners Jonathan Mesiano-Crookston and Stephen Barbier lead the practice. Barbier earned a law degree from the University of Western Ontario in 2003 and was called to the Bar of Ontario in 2004. Mesiano-Crookston is a registered patent and trademark agent for both Canada and the United States and has been ranked by Lexpert in multiple years.

The firm's practice centers on corporate and commercial litigation, construction disputes and liens, franchise law, and intellectual property. It acts for both franchisors and franchisees in disputes over disclosure, rescission, and terminations, and for owners, developers, contractors, and insurers in construction lien and defect claims. Of counsel Niki Kanavas spent eight years teaching law at Seneca College before joining the firm and has appeared before the Ontario Superior Court of Justice, the Divisional Court, the Court of Appeal, and the Federal Court of Appeal.

The neighbourhood

The firm's office at 18 King Street East is an 18 storey building in Old Toronto's financial core, a short walk from St. Lawrence Market and the King East design district. It's a stretch of downtown where older commercial buildings sit alongside finance and design firms, a fitting setting for a practice built around business and construction disputes.

One of the firm's lawyers has appeared before the Ontario Superior Court of Justice, the Divisional Court, the Court of Appeal, and the Federal Court of Appeal, keeping much of the caseload tied to Toronto's court system even though clients come from across the GTA and Ontario.
