When did Canada strengthen its ties with the United States and other trading partners?

Discover Canada records this in one direct sentence. The guide writes: Between 1945 and 1970, as Canada drew closer to the United States and other trading partners, the country enjoyed one of the strongest economies among industrialized nations. The timeframe the test wants is therefore between 1945 and 1970.

The 25-year postwar period was decisive. Discover Canada commits the strengthening of trade ties to a precise period: 1945 to 1970. This window covers the post-Second-World-War economic boom — when Canada moved from wartime production to peacetime trade-driven growth. The result was "one of the strongest economies among industrialized nations."

The era brought broad prosperity. Discover Canada writes that "in 1951, for the first time, a majority of Canadians were able to afford adequate food, shelter and clothing" — meaning the post-1945 boom translated into rising living standards across the population. Earlier in the same passage: "the discovery of oil in Alberta in 1947 began Canada's modern energy industry," contributing to the trade-and-growth period. So the 1945–1970 window saw multiple foundational achievements: oil discovery (1947), food-shelter-clothing security (1951), and strong economic performance among industrialised nations.

The trading relationship continues. Discover Canada writes: "Today, Canadians enjoy one of the world's highest standards of living — maintained by the hard work of Canadians and by trade with other nations, in particular the United States." So the trade ties strengthened between 1945 and 1970 have continued to shape modern Canadian prosperity. The U.S. remains "our largest international trading partner," with "over three-quarters of Canadian exports destined for the U.S.A." The 1988 Canada-U.S. free trade agreement and the 1994 expanded NAFTA are direct legacies of the 1945–1970 trade-deepening era. Today Canada is part of the G8 group of leading industrialized countries and has one of the ten largest economies in the world. So when the test asks when Canada strengthened ties with the U.S. and other trading partners, the source-precise answer is the 1945–1970 period.

The question is testing whether new citizens know when Canada deepened trade ties. Discover Canada commits to one period: between 1945 and 1970. The right test answer matches that.

The wrong answer choices each pick a different period. "Between 1920 and 1940" includes the Roaring Twenties boom and the Great Depression — neither is the period the source names. "Between 1975 and 1990" is a later period. "Between 1990 and 2010" is more recent. Only 1945–1970 — the post-Second-World-War period the source names — matches.
