Kestenberg Litigation

What Kestenberg Litigation does

Kestenberg Litigation LLP is a Toronto-based boutique commercial litigation and dispute resolution law firm founded in 2023 by Marc Kestenberg and Michael Kestenberg. The firm represents clients across a broad range of contentious matters, including business and contract disputes, shareholder and partnership disputes, real property and commercial leasing disputes, professional negligence defence, employment matters, franchising disputes, bankruptcy and insolvency work, debt collection, and appellate advocacy before Ontario courts. It also operates a dedicated alternative dispute resolution service under the Kestenberg Mediation brand, led by Marc Kestenberg.

The firm's client base spans large publicly traded enterprises (including Schedule A Banks and Stewart Title Guarantee Company), small and family-owned businesses, and individual professionals facing negligence claims. All lawyers at the firm are designated preferred defence counsel by LawPRO, the professional liability insurer for Ontario lawyers, making professional negligence defence a structural referral vertical. Marc Kestenberg has been peer-recognized as a top commercial litigator by Post City Magazine (2022–2025) and is ranked by Lexpert as a Leading Lawyer for Corporate and Commercial Litigation.

Kestenberg Litigation generates revenue exclusively through professional legal fees on litigation matters (quote-based, not publicly disclosed) and through mediation services priced at $5,995 plus HST for a full day (7 hours) and $3,995 plus HST for a half day (3.5 hours), with $750 per hour for additional time and no charge for preparation. The firm operates a single Toronto office at 2300 Yonge St., Suite 1600, with no disclosed proprietary technology platform, no external investors, and no parent company. Client acquisition is driven primarily by professional referrals, peer reputation, and industry rankings rather than active digital marketing.
