Jonathan Ku was admitted as a solicitor of the High Court of Hong Kong in 2022 and called to the Ontario Bar in 2024. He practices civil and commercial litigation with particular capability in cross-jurisdictional matters requiring coordination across different legal systems, languages, cultural contexts, and time zones.
Jonathan’s litigation practice developed through high-conflict family law matters in Hong Kong—contentious custody and financial disputes that established his operational framework for emotionally charged, adversarial proceedings. This foundation carried into an accelerated trajectory handling multi-party commercial disputes, insolvency proceedings, real estate litigation, and employment matters across jurisdictions.
In Canada, he has appeared at multiple levels: tribunals (HRTO, LTB, Small Claims Court, TICO), Superior Court, bankruptcy proceedings, and Court of Appeal. His approach emphasizes strategic collaboration with clients to develop practical solutions when conventional paths prove inadequate.
Jonathan is trilingual (English, Cantonese, Mandarin) and maintains active media presence in both Hong Kong and Canadian diaspora communities.

Our civil litigation practice assists individuals and businesses with commercial and contractual disputes, real estate matters, shareholder disputes, construction claims, and other civil proceedings. We take the time to understand each matter and develop a focused approach to achieving a practical resolution.
