Where is the Canadian Shield rich in minerals?

The Canadian Shield is a vast geological region rich in minerals that stretches across central and eastern Canada. Discover Canada mentions the Canadian Shield once, in connection with Quebec's economy. The guide writes: The resources of the Canadian Shield have helped Quebec to develop important industries, including forestry, energy and mining. So the guide describes the Shield as a resource base — and Quebec, the province with the deepest Shield-resource ties, is where the term is anchored.

The Shield extends well beyond Quebec. Discover Canada's description of Quebec's "forestry, energy and mining" industries — driven by Shield resources — applies similarly to Ontario, Manitoba, Labrador, and parts of the northern territories. Each of these regions has Shield bedrock with mineral deposits — gold, nickel, copper, iron, and more. So the mineral wealth of the Shield is a continental-scale resource, even if the guide's only direct mention ties it to Quebec.

The Shield supports Canadian mining widely. Discover Canada writes that natural-resources industries — including mining — "have played an important part in the country's history and development." The Shield is the geological foundation for much of that mining activity. Saskatchewan has "the world's richest deposits of uranium and potash," and Saskatoon, the largest city in Saskatchewan, is described as "the headquarters of the mining industry." So mineral wealth runs from the Shield's central-and-eastern Canadian rocks through to the country's broader mining economy.

The Shield is one part of Canada's vast geography. Discover Canada writes that "Canada is the second largest country on earth — 10 million square kilometres," divided into five regions: Atlantic Provinces, Central Canada, Prairie Provinces, West Coast, and Northern Territories. The Shield runs through Central Canada (Quebec and Ontario) and bridges to the Northern Territories — geographically uniting the eastern interior of the country with the Arctic. The Shield's mineral wealth is one of the natural-resource pillars on which Canada's economy still rests.

The question is testing whether new citizens understand the geographic spread of the Canadian Shield's mineral wealth. The Shield stretches across central and eastern Canada, not confined to a single province. The right answer is the broad description.

The wrong answer choices each restrict the Shield to a single area. Although Discover Canada mentions the Shield in connection with Quebec specifically, the geological formation extends much more broadly. "Only in Ontario," "Only in the Northern territories," or "Only in Quebec" each understate the Shield's reach. Only the across-central-and-eastern-Canada answer captures its true scope.
