About Kestenberg Litigation
Kestenberg Litigation LLP is a commercial litigation firm in midtown Toronto, with six lawyers working out of the Yonge Eglinton Centre at 2300 Yonge Street. The firm handles business and contract disputes, shareholder and partnership disputes, real property and leasing disputes, employment and labour disputes, franchising disputes, bankruptcy and insolvency matters, debt collection, appeals and arbitrations. It also defends lawyers, judges, investment advisors and investment dealers in professional negligence claims.
Marc Kestenberg founded the firm in 2023, holding a law degree from Osgoode Hall and an M.B.A. from the Schulich School of Business, both earned at York University in 2002, and a 2004 call to the Ontario bar. The firm's founder started at Shearman & Sterling in New York, then practised at Goodman and Carr, Ogilvy Renault and Norton Rose Fulbright in Toronto, and was a partner at Kestenberg Siegal Lipkus from 2015 before opening Kestenberg Litigation. Marc Kestenberg also leads Kestenberg Mediation, a separate commercial mediation practice run alongside the firm's litigation work.
Michael Kestenberg, a founding partner, was called to the Ontario bar in 1976 and has appeared before every level of court, including the Supreme Court of Canada. Several of the firm's lawyers serve as preferred counsel for LawPRO, the insurer that defends Ontario lawyers sued for professional negligence.

Who handles what
The neighbourhood
The firm's office sits in the Yonge Eglinton Centre, a two tower complex at the northwest corner of Yonge and Eglinton that has anchored midtown Toronto since construction finished in 1974. A 2016 revitalization added seven floors to the 2300 Yonge Street tower, replaced its exterior with curtain wall glass, and added a rooftop patio. The building connects by underground tunnel directly to Eglinton subway station, giving clients a straightforward transit route in from across the city for an in person meeting or a Kestenberg Mediation session.
