His practice focuses on complex commercial disputes, fraud and asset recovery litigation, medical malpractice, catastrophic personal injury claims, professional liability matters, shareholder disputes, injunction proceedings, and employment litigation.

Marc is particularly recognized for his work in fraud litigation and investigations. He regularly advises clients facing allegations of fraud, misappropriation of funds, breach of fiduciary duty, civil conspiracy, asset tracing, and emergency recovery proceedings. He has extensive experience obtaining and defending extraordinary remedies, including Mareva injunctions, Anton Piller orders, Norwich orders, tracing orders, and other urgent court interventions designed to preserve assets and protect clients’ interests.

Over the course of his career, Marc has represented a diverse range of sophisticated clients, including national banking institutions, Crown corporations, multinational corporations, municipalities, public bodies, healthcare professionals, lawyers and business owners. Notably, he acted as outside counsel to the City of Ottawa for more than a decade, advising and representing the municipality in complex litigation and risk-management matters. His extensive experience working with public institutions and regulated organizations provides him with a unique understanding of governance, accountability, and strategic dispute resolution.

Marc’s commercial litigation practice encompasses shareholder and partnership disputes, breach of contract claims, construction disputes, commercial leasing matters, banking litigation, fraud recovery, insolvency-related proceedings, and business torts. He is frequently retained when significant financial, reputational, or operational interests are at stake.

In addition to his commercial practice, Marc has earned recognition for his work in medical malpractice and catastrophic injury litigation, particularly in cases involving traumatic brain injuries, life-altering injuries, and complex damages claims.
