Canada joined with other democratic countries of the West to form which military alliance?

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 military alliance the test wants is therefore NATO (the North Atlantic Treaty Organization).

Two alliances paired in the same passage. Discover Canada commits Canada to TWO Cold War alliances: (1) NATO — the North Atlantic Treaty Organization, with other democratic countries of the West; and (2) NORAD — the North American Aerospace Defence Command, with the United States. So NATO is the broader Western alliance; NORAD is the bilateral Canada-U.S. air-defence pact. Both were formed as Canadian responses to the Cold War.

The Cold War triggered both alliances. Discover Canada writes: "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. 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)." So both NATO and NORAD were established after the Soviet-controlled Communist bloc absorbed eastern Europe — making them Cold War responses.

Canada has multiple international defence engagements. Discover Canada writes that Canada also "joined international organizations such as the United Nations (UN). It participated in the UN operation defending South Korea in the Korean War (1950–53), with 500 dead and 1,000 wounded. Canada has taken part in numerous UN peacekeeping missions in places as varied as Egypt, Cyprus and Haiti, as well as in other international security operations such as those in the former Yugoslavia and Afghanistan." So beyond NATO and NORAD, Canada engages internationally through the UN — both in war operations (Korean War) and peacekeeping (Egypt, Cyprus, Haiti). Together, NATO + NORAD + UN form Canada's three main international defence-and-security frameworks. So when the test asks the military alliance Canada formed with other democratic Western countries, the source-precise answer is NATO.

The question is testing whether new citizens know the named NATO alliance. Discover Canada commits to one alliance: NATO (the North Atlantic Treaty Organization). The right test answer matches that.

The wrong answer choices each substitute a different organization. "SEATO" was a Southeast-Asia treaty organization — Canada was not a member. "The Commonwealth" is the network of Commonwealth nations linked through the Sovereign — but it is not a military alliance. "NORAD" is the North American Aerospace Defence Command (with the United States) — a bilateral air-defence pact, not the broader Western military alliance. Only NATO matches the source's named Western military alliance.
