Although Article 26 of the Canada-France Income Tax Convention did not specifically provide (as did paragraph 2 of Article 27 of the Canada-U.S. Income Tax Convention) that the requested state was required to endeavour to obtain the requested information in the same way as if its own taxation was involved, it nonetheless was clear, in light of the wording of Article 26 and in light of the Commentary to the OECD Model Convention that the requested state was required not only to exchange information already gathered by it, but also to obtain information by use of administrative measures, such as issuing a requirement under s. 231.2(1) of the Act.
