Mexico ratified the new income tax treaty and protocol between Mexico and Canada, signed on 12 September 2006. On 27 February 2007, the Mexican Senate approved the treaty and the relevant Decree was published in the Official Gazette of 10 April 2007. Once the new treaty enters into force (on the date of exchange of notes through diplomatic channels), it will replace the Mexico-Canada income tax treaty and protocol of 8 April 1991.
