The agreement entered into force on 1 April 1995 when five countries ratified the convention (Denmark, Finland, Norway, Sweden and the United States). Although it was signed by Canada in 2004, the convention has never been in force in Canada. The Agreement was amended by the 2010 Protocol in accordance with the OECD EOIR International Standard. Canada ratified the amended convention on November 21, 2013; it entered into force in 2014.  Under the current double taxation conventions, the first convention was signed with France in 1975. By 1958, Canada had already signed 11 agreements (with Australia, Denmark, France, Germany, Ireland, the Netherlands, New Zealand, South Africa, Sweden, the United Kingdom and the United States). All were created after the original publication of the OECD (Government of Canada) model. (2014a). List of contracts. Global Affairs Canada, accessed July 27, 2016.) In this context, the OECD has developed the Multilateral Agreement on the Multilateral Authority on The Automatic Exchange of Country-by-Country Reports (CbC MCAA). It is largely inspired by the MCAA SIR and is based on Article 6 of the Multilateral Convention on Mutual Legal Assistance; For exchanges between two signatories to be effective, each competent authority must have completed the notification procedure, which requires, inter alia, the implementation of appropriate national legislation and a list of legal systems allowing the automatic exchange of CbCR, reciprocal or not. Tax Information Exchange Agreements (TIEAs) provide for the exchange of information on request concerning a criminal or civil tax investigation or civil tax matters under investigation.  A TIEA model was developed by the OECD Global Forum Working Group on Effective Exchange of Information.
This agreement, published in April 2002, is not a binding instrument, but includes two model bilateral agreements. A large number of bilateral agreements have been based on this agreement (see below). Thus, since 2014, Canada may, upon request, share information with other signatories for whom the convention has entered into force, to the extent that such information is foreseeable for the application of tax rules. The interactive illustration of the Multilateral Agreement on Financial Accounts shows the countries that have signed the Agreement the data on the signature and entry into force as well as the status of the necessary legislation. The multilateral authority`s agreement on the automatic Exchange of Country-by-Country Reports shows the signatories of the agreement. Canada is one of 83 signatories to the CBC MCAA. According to the credit rating agency, the first exchange of information with other jurisdictions was expected in June 2018. All TIEAs in Jersey comply with international standards and are broadly in line with the Organisation for Economic Co-operation and Development (OECD) Model Agreement on the Exchange of Information in Tax Matters. In addition to the exchange of information, the parties to the multilateral convention may receive assistance in the collection of tax and the service of documents. However, in accordance with its reservations, Canada is not obliged to provide assistance to another country for the collection of tax or the service of documents. Jersey may also exchange tax information with other countries under double taxation treaties, the multilateral convention and EU Member States under the EU Savings Tax Directive.
The legality of intergovernmental agreements (ISAs) has been questioned on the grounds that any agreement between governments that significantly binding any government constitutes a treaty. Since the U.S. Constitution does not allow the executive branch to unilaterally implement treaties without the consent of the Senate, many argue that GAs have no basis in the U.S. Constitution.  THE ISGs were not described or provided for in the Fatca legislation, but were designed and implemented a posteriori, when it became clear that FATCA would fail without it.  To date, 107 jurisdictions, including Canada, have signed the CRS MCAA. . .
