from Canadian policymakers. It notes many Canadian economists supported "ambitious" goals like a single market, with some supporting a monetary union, but that they believed the incremental approach was more appropriate at the time. Canada's central bank governor is quoted in the cable as having said that a monetary union is "an issue that should be considered once we have made more progress towards establishing a single market." The National Posts Robert Hiltz described the cable in June 2011 as discussing "the obstacles surrounding the merger of the economies of Canada, the United States and Mexico in a fashion similar to the European Union." Two months later at the March meeting of North American leaders, the Security and Prosperity Partnership of North America (SPP) was formed. It was described by the leaders of Canada, Mexico and the United States as a dialogue to provide greater cooperation on security and economic issues. In response to later concerns, a section was put up on the initiative's site clarifying the SPP was not a legal agreement, that the initiative "does not seek to rewrite or renegotiate NAFTA", and that the partnership itself "creates no NAFTA-plus legal status." A number of academics and government officials at the time viewed the SPP as moving North America towards greater integration. In May 2005, the Task Force published a report praising the SPP initiative and pushing for greater economic integration by 2010. They repeated their call for the "establishment by 2010 of a North American economic and security community, the boundaries of which would be defined by a common external tariff and an outer security perimeter." In the report the Task Force said that a North American Community, which would be similar to the European Community which preceded the EU, should not rely on "grand schemes of confederation or union" and did not suggest a supranational government or a common currency. The Task Force's recommendations included developing a North American common market and security perimeter, among other common goals. The SPP initiative was officially ended in August 2009 though the North American Leaders' Summit and most of the working groups set up under the initiative remain active. Several advocates of integration saw the SPP as being insufficient. One criticism was that the governments lacked a "vision of what North America might become" and as such did not provide the proper context that would allow the initiative to
