Who said immigrant groups should retain their individuality and each make its contribution to the national character?

Discover Canada records this in one direct sentence. The guide writes: John Buchan, the 1st Baron Tweedsmuir, was a popular Governor General of Canada (1935–40). Immigrant groups, he said, "should retain their individuality and each make its contribution to the national character." The speaker the test wants is therefore John Buchan.

The speaker is identified by three details. Discover Canada commits John Buchan to THREE specific identifications: name (John Buchan), title (1st Baron Tweedsmuir), and role (Governor General of Canada, 1935–40). So the source pins down the speaker precisely — the same man known as a famous novelist became the popular Governor General who delivered the unity-in-diversity phrasing the test asks about.

The full quotation is twofold. Discover Canada commits two parts to Buchan's quote: first, that immigrant groups "should retain their individuality and each make its contribution to the national character," and second, that "each could learn 'from the other, and … while they cherish their own special loyalties and traditions, they cherish not less that new loyalty and tradition which springs from their union.'" So the message is balanced: retain individuality AND make a contribution to the unified national character. The two ideas are paired — diversity and unity together.

The speech has a specific date and place. Discover Canada commits Buchan's quote to a specific occasion: the Canadian Club of Halifax, 1937. So the words were delivered at a public address in Halifax, Nova Scotia, in 1937 — three years after Buchan's appointment as Governor General and two years before the Second World War. The guide's section title is Unity in Diversity — the foundational Canadian principle Buchan articulated. He also appears in the guide in a photograph: "Lord Tweedsmuir, Governor General of Canada (novelist John Buchan), in native attire," wearing a Blood (Kainai First Nation) headdress as the 15th Governor General. So when the test asks who said immigrant groups should retain individuality while contributing to the national character, the answer is John Buchan — also known as the 1st Baron Tweedsmuir, Governor General 1935–40, novelist, and orator at Halifax in 1937.

The question is testing whether new citizens know who delivered the unity-in-diversity phrasing about immigrant groups. Discover Canada commits to one speaker: John Buchan. The right test answer matches that.

The wrong answer choices each substitute a different Canadian historical figure. The first option served as Prime Minister much later (1963–68) and is not credited with this quote in the guide. The third option served as Prime Minister during Buchan's tenure but is not the speaker — Buchan is identified as the orator. The fourth option is a later Prime Minister whose name is not associated with this phrasing in the source. Only John Buchan — the 1st Baron Tweedsmuir, Governor General 1935–40 — matches the source.
