About Kastner Ko LLP

Kastner Ko LLP is a law firm at 55 University Avenue in downtown Toronto, focused on employment and union-side labour law, human rights, administrative and public law, professional discipline, and civil litigation. The firm traces back to 2015, when it operated as Kastner Lam LLP. It later took its current name, reflecting partners Danny Kastner and Gregory Ko, and the firm's former web address, kastnerlam.com, now redirects to kastnerko.com.

Kastner, a University of Toronto law graduate called to the Ontario bar in 2007, practices employment and labour law, human rights, defamation, and professional discipline, and has appeared as counsel in cases before the Supreme Court of Canada. Ko holds a law degree from McGill University and a Master of Laws from the University of Toronto, teaches employment law and legal ethics as an adjunct professor at the University of Toronto Faculty of Law, and practices in employment, human rights, and constitutional and administrative law. Ko speaks English and French, plus conversational Cantonese, Spanish, German, and Mandarin.

The Globe and Mail has named Kastner Ko one of Canada's Best Law Firms for Labour and Employment every year from 2022 to 2026, and Canadian HR Reporter included it among Canada's Best Employment Law Firms for 2023. The firm's lawyers have been featured in national outlets, including the CBC, CTV, and the Toronto Star, on employment, human rights, and public accountability cases, and the firm can take some matters on a contingency fee basis.
