Which international organization is Canada a member of?

Discover Canada records this in one direct sentence. The guide writes: Canada 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. The international organization the test wants is therefore the United Nations (UN).

Canada has been an active UN participant. Discover Canada commits Canadian UN involvement to TWO specific kinds of operations: UN missions in war (Korean War, 1950–53) and UN peacekeeping (numerous missions). So Canada has used UN membership for both combat operations (defending South Korea) and peacekeeping (in places like Egypt, Cyprus, and Haiti).

The Korean War was foundational to UN engagement. Discover Canada commits the Korean War contribution to specific casualty figures: 500 dead and 1,000 wounded — meaning Canadian sacrifice in support of UN operations was substantial. The war ran in the early 1950s, with Canada one of the UN coalition members defending South Korea against Communist aggression.

Peacekeeping has shaped Canadian UN identity. Discover Canada commits Canadian peacekeeping to multiple named theatres: Egypt, Cyprus, Haiti. These are joined by other international security operations: former Yugoslavia and Afghanistan. So Canadian international military engagement runs through both UN-blue-helmet peacekeeping and broader coalition operations. Canada is also part of NATO (the North Atlantic Treaty Organization, formed during the Cold War) and NORAD (the North American Aerospace Defence Command, with the United States) — making the country part of multiple alliance frameworks. The Sovereign also "links Canada to 53 other nations" through the Commonwealth, and Canada helped found La Francophonie in 1970. So Canadian international membership is broad — but the United Nations is one of the named foundational organizations Canada belongs to. When the test asks which international organization Canada belongs to, the source-precise answer is the United Nations.

The question is testing whether new citizens know an international organization Canada belongs to. Discover Canada commits to one organization explicitly: the United Nations. The right test answer matches that.

The wrong answer choices each substitute a different organization. The first option is for European countries — Canada is not a member. The second option is a regional Southeast-Asian grouping — Canada is not a member. The fourth option is for African states — Canada is not a member. Only the United Nations matches the source.
