The World Trade Organization (WTO) is the only international organization that regulates global trade. It is based in Geneva, Switzerland. Canada is one of its 164 members. The country plays a central role in the WTO and was also a key member of the General Agreement on Tariffs and Trade that preceded it. In addition to helping craft the WTO’s dispute resolution systems, Canada is among those countries most directly involved in its trade dispute cases.
The North Atlantic Treaty Organization (NATO) was created on 4 April 1949. It was Canada’s first peacetime military alliance. It placed the country
in a defensive security arrangement with the United States, Britain, and Western Europe. (The other nine founding nations were France, Norway, Denmark, Belgium, Netherlands, Luxembourg, Portugal, and Italy.) During the Cold War,
NATO forces provided a frontline deterrence against the Soviet Union and its satellite states. More recently, the organization has pursued global peace and security while asserting its members’ strategic interests in the campaign against Islamic terrorism.
As of 2021, there were 30 member countries in NATO.
The Commonwealth of Nations is made up of 54 countries, including Canada, that were for the most part once part of the British Empire. They work together on international policy and hold a major sports event every four years. It is one of the world’s oldest political associations of states.
