Tax Controversy and Litigation
Our tax controversy and litigation lawyers have extensive experience in dealing with all levels of the Canadian tax authorities, the tax dispute process and all phases of tax controversy.


Our team is ranked as a Tier 1 Firm for Tax Controversy in World Tax 2022 and has broad experience in all phases of tax controversy—from the planning and implementation of transactions, to tax filings, audits, assessments, litigation and appeals. Throughout the process, we bring sophisticated tax advice together with effective advocacy to guide clients in their dispute resolution.

In the audit process, we help clients develop sound disclosure strategies and marshal compelling advocacy and messaging. When assessments are issued, we help prepare submissions to relevant authorities, as well as provide advice for audits and where necessary, we engage in litigation. We work closely with our commercial litigation lawyers on cases that fall at the intersection of judicial review and tax law, in a collaborative way that plays to the diversity of our strengths.
