Who we are and how to contact us

Who we are

Where a person considers that the actions of Canada or a treaty partner result or may result in taxation not in accordance with a particular treaty, the person may request competent authority assistance. Assistance by the competent authority is generally provided under the mutual agreement procedure (MAP) article contained in Canada's tax treaties.

Canada's income tax treaties define the Canadian competent authority as the Minister of National Revenue or the Minister's authorized representatives.

What we do

The competent authority

The competent authority also

  • resolves issues concerning the application of tax treaties generally where specific taxpayers are not involved and interpretive issues involving treaty partners;
  • considers the recognition of foreign pension plans allowed under certain treaties; and
  • considers applications under paragraph 6, of Article XXIX A (Limitation on Benefits) in the Canada-US Tax Convention.


For more details, refer to IC71-17, Guidance on Competent Authority Assistance Under Canada's Tax Conventions.
