About Katzman Litigation Professional Corporation

Katzman Litigation Professional Corporation is a small civil and commercial litigation firm in Toronto, led by principal Michael A. Katzman. The firm works out of an office on University Avenue and fields three lawyers alongside three law clerks and paralegals. Its practice runs across commercial disputes such as shareholder and partnership conflicts, oppression remedies, and contract disagreements, real estate litigation over broken purchase and sale agreements and mortgage disputes, estate litigation including will challenges and dependants' support claims, employment disputes covering wrongful and constructive dismissal, and collection and enforcement work for lenders and landlords. The firm describes its approach as practical advice, creative approaches, and proven results, with an emphasis on proportionality between the cost of a dispute and what a client stands to gain from it.

The firm's managing partner holds a Master of Laws from the University of Toronto, was called to the bar in 2016, and has appeared before the Court of Appeal for Ontario, the Superior Court of Justice, and courts in Newfoundland and Labrador and Alberta, alongside a stint as an adjunct professor at Durham College and ongoing work as counsel for Pro Bono Ontario.

The neighbourhood

Katzman Litigation's office at 393 University Avenue, Suite 1607, is in the same downtown Toronto building as the Ontario Superior Court of Justice's civil courthouse, the court that handles the motions, case conferences, pretrials, and construction lien matters that make up much of the firm's commercial and real estate litigation work. For a firm built around courtroom disputes, having chambers inside the courthouse building rather than a few blocks from it is a genuine practical fit, not just a downtown address.

University Avenue is one of Toronto's principal north to south routes through the core, connecting Queen Street to the hospital and university district further north, which puts the firm within an easy walk of the broader downtown legal and institutional community it serves.
