Tax Disputes Tax Disputes

Taxpayers navigating tax audits, assessments and disputes with the Canada Revenue Agency (CRA) face a complex, challenging and often times lengthy administrative process. Recent expansions of the CRA’s audit powers and enforcement activities have created an environment of heightened scrutiny for taxpayers looking to resolve audits and disputes efficiently.

The Osler Tax Disputes team is widely recognized as the leading practice in Canada, drawing from our tax planning, advisory and litigation practices, when needed, to strategically guide clients through a tax dispute. Our team has extensive experience proactively managing and successfully resolving audits and administrative appeals with the CRA. Clients are advised of their rights (and obligations) when dealing with the CRA and are assisted with substantive submissions to the CRA. Our in-depth knowledge of the tax law, the CRA’s decision-making processes, and years of experience successfully managing tax disputes, including by way of proceeding to litigation when necessary, typically enables clients to successfully resolve tax disputes without the need for a trial.

Our lawyers work extensively with economists and other experts, as well as with leading advisors in other jurisdictions, in the process of resolving transfer pricing disputes with the CRA, through the competent authority process or through the courts, when required.
