Gareth D’Costa, J.D.
Senior Litigation Lawyer
Gareth D’Costa is a Senior Litigation Lawyer at Achkar Law. His practice spans commercial litigation, employment and human rights matters, real estate disputes, and breach of contract claims. He represents both individuals and organizations, helping clients resolve legal issues with a practical, solutions-oriented approach, and he finds the work meaningful because it lets him guide people through challenging periods and toward outcomes they can see and feel in real terms.
Gareth began his legal career at the Ministry of Finance, Legal Services Branch, where he advised Ontario’s Financial Services Policy Division. His work included regulatory and oversight matters involving Crown agencies such as the Ontario Securities Commission (OSC), the Financial Services Commission of Ontario (FSCO), and the Financial Services Regulatory Authority of Ontario (FSRA). He also acted as counsel to the Ontario Financing Authority’s (OFA) Corporate Finance Division, advising on provincial lending and private sector procurement. Working closely with the office responsible for the Spring Budget and Fall Economic Statement, Gareth developed a diverse skill set at the intersection of law, policy, and economics, experience that continues to benefit his clients.
Before joining Achkar Law, Gareth practised full-service civil litigation. He represented clients in matters involving residential and commercial purchase and sale agreements, oppression remedies, tax appeals, expropriation, and administrative law. He regularly appeared before the Small Claims Court, Superior Court of Justice, and various provincial tribunals to help secure favourable outcomes.
During law school at the University of Toronto, Gareth volunteered with Downtown Legal Services and Law Help Ontario, supporting access to justice and community legal work.
A first-generation immigrant and the first in his immediate family to pursue post-secondary education, Gareth brings that same drive to his clients’ files. Outside the office, he enjoys cooking, exploring the city, and spending time with his dog, Rosie.
