Olivier's practice focuses on tax litigation and controversy, advising Canadian and international clients on complex tax audits and disputes both in and out of court. As a litigator, he regularly appears before both the federal and Québec courts on tax matters, including at the appellate level. A thought leader in Canadian tax law and former governor of the Canadian Tax Foundation, Olivier regularly contributes to the tax community through speaking and writing on significant tax issues.
