Canada–United States Tax Convention Act, 1984 — C-10.7 ARTICLE XXVII
Article XXVII (Exchange of Information) of the Convention shall be deleted and replaced by the following: ARTICLE XXVII Exchange of Information 1 The competent authorities of the Contracting States shall exchange such information as may be relevant for carrying out the provisions of this Convention or of the domestic laws of the Contracting States concerning taxes to which this Convention applies insofar as the taxation thereunder is not contrary to this Convention. The exchange of information is not restricted by Article I (Personal Scope). Any information received by a Contracting State shall be treated as secret in the same manner as information obtained under the taxation laws of that State and shall be disclosed only to persons or authorities (including courts and administrative bodies) involved in the assessment or collection of, the administration and enforcement in respect of, or the determination of appeals in relation to the taxes to which this Convention applies or, notwithstanding paragraph 4, in relation to taxes imposed by a political subdivision or local authority of a Contracting State that are substantially similar to the taxes covered by this Convention under Article II (Taxes Covered). Such persons or authorities shall use the information only for such purposes. They may disclose the information in public court proceedings or in judicial decisions. The competent authorities may release to an arbitration board established pursuant to paragraph 6 of Article XXVI (Mutual Agreement Procedure) such information as is necessary for carrying out the arbitration procedure; the members of the arbitration board shall be subject to the limitations on disclosure described in this Article. 2 If information is requested by a Contracting State in accordance with this Article, the other Contracting State shall use its information gathering measures to obtain the requested information, even though that other State may not need such information for its own tax purposes. The obligation contained in the preceding sentence is subject to the limitations of paragraph 3 but in no case shall such limitations be construed to permit a Contracting State to decline to supply information because it has no domestic interest in such information. 3 In no case shall the provisions of paragraph 1 and 2 be construed so as to impose on a Contracting State the obligation: (a) To carry out administrative measures at variance with the laws and administrative practice of that State or of the other Contracting State; (b) To supply information which is not obtainable under the laws or in the normal course of the administration of that State or of the other Contracting State; or (c) To supply information which would disclose any trade, business, industrial, commercial or professional secret or trade process, or information the disclosure of which would be contrary to public policy ( ordre public ). 4 For the purposes of this Article, this Convention shall apply, notwithstanding the provisions of Article II (Taxes Covered): (a) To all taxes imposed by a Contracting State; and (b) To other taxes to which any other provision of this Convention applies, but only to the extent that the information may be relevant for the purposes of the application of that provision. 5 In no case shall the provisions of paragraph 3 be construed to permit a Contracting State to decline to supply information because the information is held by a bank, other financial institution, nominee or person acting in an agency or a fiduciary capacity or because it relates to ownership interests in a person. 6 If specifically requested by the competent authority of a Contracting State, the competent authority of the other Contracting State shall provide information under this Article in the form of depositions of witnesses and authenticated copies of unedited original documents (including books, papers, statements, records, accounts, and writings). 7 The requested State shall allow repre
