Tax Litigation

Tax litigation lawyer

Our tax litigation team regularly challenges assessments issued to individuals, trusts and companies by Revenue Quebec and the Canada Revenue Agency (CRA).

We will advise you on any subject regarding tax litigation services, including income taxes, goods and services taxes (GST) and Québec sales taxes (QST), mandatory withholdings and deductions at the source by employers or others.

To ensure the defence of our clients our tax lawyers attend multiple continuing education seminars in order to remain informed and up to date on the jurisprudence and new decisions issued by courts in matters of taxation law, as well as the new approaches and directives taken by the taxation authorities. Indeed, this area of law is always changing and our tax litigation team defends our clients while equipped with the up-to-date information.

  • Liability of directors
  • Liability of third parties
  • Determination of the status of an independent worker or entrepreneur
