Irwin Nathanson, Q.C. is one of the top trial and appellate lawyers in British Columbia, and has litigated many of British Columbia’s leading complex business disputes.

Leading publications have remarked that: “Irwin is still going like a champ, a ‘senior statesmen’ who still doesn’t miss a beat”; “You won’t find a better litigator anywhere in the country”; “He is the biggest gun in Vancouver”; He is “resolute, cool and clinical, not to mention technically brilliant”; “Nathanson can always produce a fantastic team for significant pieces of litigation”; “He is still as good as it gets”; He is known for his “forceful, compelling and indefatigable” litigation style; He “generates unanimous acclaim among Vancouver peers”; He’s “as good a cross examiner as you’re going to find”.

Irwin and Stephen Schachter, Q.C. have been described as a “potent duo”. Most recently, together with NST’s Caitlin Ohama-Darcus, they acted as trial counsel in Concord Pacific Acquisitions v. Hong Leong Oei, a dispute valued at over $350 million, between Concord Pacific and renowned Singapore businessman and NST client Oei Hong Leong. NST’s clients were also awarded special costs, expected to be in excess of $4 million.  Irwin regularly appears in the British Columbia Supreme Court, the British Columbia Court of Appeal, and in the Supreme Court of Canada, including, with partner Julia Lockhart, representing the GVSDD (now Metro Vancouver) in Wastech Services Ltd. v. GVSDD, 2021 SCC 7. The SCC overturned a $2.88 million award made against Metro Vancouver in a decision having important implications for all contracts that provide one party with discretionary powers, building on the Supreme Court of Canada’s decisions in Bhasin v. Hrynew, 2014 SCC 71, and C.M. Callow Inc. v. Zollinger, 2020 SCC 45.

Irwin acts as counsel on a broad range of matters, with a focus on corporate commercial litigation, including large contractual and property disputes, class actions, hostile take-over bids, derivative actions, pension litigation, professional negligence, and securities matters, including shareholder disputes. He is often retained to work with major international law firms based in Eastern Canada and the United States.

Irwin is at the top of his game; consistently bringing complex matters to successful conclusion on behalf of his clients.
