David Ziegler’s robust civil litigation and arbitration practice encompasses business-critical commercial and financial disputes, class actions, product liability matters, construction matters (including adjudications), and disputes requiring international arbitration. His vast experience acting for both Canada- and US-based companies is sought after for domestic and cross-border disputes, spanning a broad range of industries including mining, rail, professional services, insurance, banking and finance, accounting, manufacturing, and construction. He is also routinely trusted to advise clients on the enforcement and recognition of foreign judgments in Canada.

A dual-qualified lawyer in New York and Ontario, David leverages experience in securities litigation and general commercial disputes gained while practicing with a leading international law firm in New York, prior to joining Fasken.

Adept in managing large and complex e-Discovery projects, David also advises clients on best practices related to document preservation and collection, the preparation and circulation of litigation holds, and the use of modern data processing tools. He leads an initiative at Fasken to ensure that the Firm maintains and provides a state-of-the-art e-Discovery process for clients.
