David Nyamsi ACIArb. Q.Arb

As a bilingual (English–French) arbitration professional with extensive international experience, I am dedicated to advancing excellence in domestic and international dispute resolution. I currently serve as the Head of Domestic and International Arbitration at Provenance Advocates LLP (Ontario, Canada), where I lead the firm’s strategic expansion of its arbitration practice and oversee complex, high-stakes matters for individuals, businesses, and multinational organizations.

In this role, I am committed to elevating Ontario’s arbitration ecosystem by providing specialized, efficient, and globally aligned ADR services. My work spans institutional and ad hoc proceedings, commercial and investment disputes, cross-border conflicts, and capacity-building initiatives—positioning both my firm and myself as trusted experts in the field.

With over a decade of experience in international arbitration, mediation, and cross-border dispute management, I have successfully managed and supervised more than 150 cases and contributed to the growth and governance of major arbitration centres. I bring a results-driven, structured approach grounded in procedural fairness, strategic clarity, and a deep understanding of comparative legal systems.

Core areas of expertise include:
• Leadership of domestic & international arbitration proceedings
• Bilingual (English–French) advocacy & professional communication
• Strategic case management, procedural design & complex problem-solving
• High-level negotiation, mediation & stakeholder engagement
• Capacity building, training & development of arbitration frameworks
• Cross-cultural communication & international collaboration

I am proud to lead a practice that reflects professionalism, independence, and excellence—values that guide every mandate we accept at Provenance Advocates LLP. We are now welcoming new appointments and mandates in domestic and international arbitration, whether institutional, ad hoc, commercial, or cross-border.
