About Daniel Chomski

Businesses, governments, public bodies and fellow professionals bring their disputes to Daniel Chomski, an associate working from Gowling WLG's Ottawa office. Commercial litigation is the core of Dan's work, and it reaches into regulatory and public law files as well as advisory mandates.

Dan's road to litigation ran through public service. Before private practice, Dan advised federal cabinet ministers, the Minister of Justice and Attorney General of Canada among them, and served as an officer in the Canadian Forces Naval Reserve. Dan was called to the Ontario bar in 2019 and has since been admitted in Yukon and Nunavut too.

Some of Dan's work has a public dimension. Dan sat on the counsel team for the City of Ottawa at the Public Order Emergency Commission and was among the city's counsel at the hearing held on November 4, 2022. On the pro bono side, Dan heads up the firm's role in Pro Bono Ontario's CERB/CRB Overpayment Program, which helps individuals take judicial review proceedings to the Federal Court.

Dan's years in government and the Naval Reserve show up in an emphasis on disciplined preparation, sound judgment and plain advice grounded in the real setting where clients have to decide.
