Nandi A. O. Deterville
Barrister & Solicitor, founder of Deterville Law Office
Nandi Deterville was born and raised on the Caribbean island of Saint Lucia. She holds a Bachelor of Arts in International Relations from Florida International University in Miami, and attended law school at the College of Law of England & Wales and BPP Law School in England. She was called to the Bars of England & Wales and Saint Lucia in July and August 2008, and practised at a small general practice firm in Saint Lucia before migrating to Toronto. She requalified as a Barrister and Solicitor and was called to the Ontario Bar in January 2017.
Ms Deterville runs Deterville Law Office in Toronto, focusing on Canadian immigration law and Ontario estate planning. Having lived in five countries other than her homeland, she has navigated the immigration policies of each, and that lived experience drives her work with people who want to make Canada their home, temporarily or permanently.
She was introduced to estate planning early in her practice in Saint Lucia and enjoys helping clients put plans in place that reduce the cost and uncertainty their loved ones face without the right Powers of Attorney, or without a properly drafted Will. With Deterville Law Office, clients get her years of experience and a compassionate focus on the best outcome.
