When did the Korean War, in which Canada participated, take place?

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 peacekeeping operations since. The years the test wants are therefore 1950–53.

Three key facts in one sentence. Discover Canada commits to 1950–53 for the Korean War; commits Canada's role to the UN operation defending South Korea; and commits the cost to 500 dead and 1,000 wounded. So the dates are not just abstract — they bracket a specific UN-led operation in which 1,500 Canadians were killed or wounded.

The Korean War fits Canada's broader UN-peacekeeping pattern. Discover Canada writes that Canada joined the UN as part of its post-war engagement with international organisations, and that the country has "taken part in numerous" peacekeeping operations since. So 1950–53 is one of the earliest examples of Canada's commitment to international collective security through the United Nations — a commitment that has continued for decades.

Cold War context shaped the Korean War. 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." The Korean War was an early hot conflict in that Cold War — communist forces from the north invaded the south, and a UN-led force came to defend South Korea. Canada's contribution included ground troops, naval vessels, and air units. By the war's end, the dividing line between the two Korean sides had been re-established along the same boundary — and Canada had paid 500 lives for that defence of South Korea.

The question is testing whether new citizens know the dates of the Korean War. Discover Canada commits to one set of dates: 1950–53. The right test answer matches that.

The wrong answer choices each pick different dates. 1939–1945 are the dates of the Second World War. 1914–1918 are the dates of the First World War. 1960–1965 do not correspond to any war involving Canada in Discover Canada. Only 1950–53 — the Korean War — matches.
