What military alliance did Canada join with other Western democracies?

Discover Canada records this in one direct sentence. The guide writes: Canada joined with other democratic countries of the West to form the North Atlantic Treaty Organization (NATO), a military alliance, and with the United States in the North American Aerospace Defence Command (NORAD). The alliance the test wants is therefore the North Atlantic Treaty Organization (NATO).

NATO is a multilateral Western alliance. Discover Canada commits NATO to "democratic countries of the West" — meaning the alliance brings together Canada with the United States and many European democracies. The guide describes it as "a military alliance", which is the core function: collective defence among the member countries.

The Cold War shaped its formation. Discover Canada writes that "the Cold War began when several liberated countries of eastern Europe became part of a Communist bloc controlled by the Soviet Union under the dictator Josef Stalin." NATO was created in response — a collective defence alliance to deter Soviet expansion in Europe. Canada's NATO membership has continued for decades, making it a foundational part of the country's foreign and defence policy.

NATO is different from NORAD. Discover Canada's text distinguishes the two: NATO is the multilateral Western alliance; NORAD (the North American Aerospace Defence Command) is the bilateral Canada-U.S. command focused on North American airspace. So Canada is in both — but the question's "with other Western democracies" clue points specifically to the multilateral organisation, NATO. Other international organisations Canada belongs to include the United Nations (where Canada participated in the UN operation defending South Korea in the Korean War, 1950–53) and the G8 group of leading industrialized countries.

The question is testing whether new citizens know which military alliance Canada joined with other Western democracies. Discover Canada commits to one alliance: the North Atlantic Treaty Organization (NATO). The right test answer matches that.

The wrong answer choices each pick a different organisation. The first option was the Cold War counter-alliance led by the Soviet Union — Canada is not a member; it joined NATO instead. The third option is a global organisation that includes both Western and other countries, not specifically a Western military alliance. The fourth option is a bloc of European countries, not a military alliance Canada joined. Only NATO matches.
