In working with us, clients gain a team with experience on some of the most complex tax issues and precedent-setting cases across the country. Our expertise encompasses the entire gamut of tax controversies, including with respect to audits, requests for information, objections, searches and seizures and appeals. We provide experienced representation before all tax authorities and Courts, including the Tax Court of Canada.

With a reputation as Canada's preeminent litigation firm for over 150 years, we have successfully advised and defended domestic and international corporations, financial institutions, resource companies, companies in the technology space and manufacturers, as well as high net-worth individuals on tax-related disputes.

Seamless tax law advice - no matter the issue

Our tax litigators work hand in hand with our tax planning teams in corporate and commodity tax to formulate the most powerful arguments in support of your position.

We support your tax plans to avert potential reassessments, guide you through effective audit conduct and challenge excessive practices through judicial appeals.

Thought leaders at the forefront of industry

The tax authorities know us and our reputation. We frequently provide recommendations to the Department of Finance on legislative amendments to Canada’s tax law, and many of our lawyers have developed additional acumen working within the Department of Justice, the Rulings Directorate of the Canada Revenue Agency, the Department of Finance and the Tax Court. Serving on advisory committees with senior government officials, we give timely and important insights into the development of tax policy, legislation and administrative practice.

Tax controversies do not have to be a complicated maze of rules and compliance requirements - not with us by your side.
