The cities of the northwest, such as Edmonton, Langley, and Victoria, all started as:

Discover Canada records this in one direct passage about the fur trade. The guide writes: The Hudson's Bay Company, with French, British and Aboriginal employees, came to dominate the trade in the northwest from Fort Garry (Winnipeg) and Fort Edmonton to Fort Langley (near Vancouver) and Fort Victoria—trading posts that later became cities. The origin the test wants is therefore fur trading posts.

Four named forts became four named cities. Discover Canada commits the urban origin of the northwest to FOUR specific forts that all became modern Canadian cities: Fort Garry (now Winnipeg), Fort Edmonton (now Edmonton), Fort Langley (near Vancouver), and Fort Victoria (now Victoria). So the named pattern is unmistakable — northwest urbanisation grew out of the fur-trading network. Each fort was a Hudson's Bay Company outpost first, and the surrounding settlement grew into the modern city later.

The fur trade drove the cross-continental network. Discover Canada commits the dominant trading company to one named entity: the Hudson's Bay Company. The HBC was granted exclusive trading rights in 1670 by King Charles II. The company's workforce — French, British, and Aboriginal employees together — built the trading-post network from Manitoba to Vancouver Island. So the cities of the Canadian northwest carry both an Indigenous and a European-colonial commercial heritage in their physical foundation.

The fur economy shaped early Canadian commerce. Discover Canada writes elsewhere that "the first companies in Canada were formed during the French and British regimes and competed for the fur trade," and that "for centuries Canada's economy was based mainly on farming and on exporting natural resources such as fur, fish and timber, transported by roads, lakes, rivers and canals." So the fur trade was not just one industry among many — it was the foundational commerce that built the company posts that became the cities. The trading-post-to-city sequence is part of a broader Canadian pattern in which natural-resource exports drove the original economic geography. So when the test asks how the northwest cities — Edmonton, Langley, Victoria — started, the source-precise answer is fur trading posts.

The question is testing whether new citizens know the origin of the northwest cities. Discover Canada commits to one origin: fur trading posts. The right test answer matches that.

The wrong answer choices each substitute a different origin. "Military forts" misframes the named forts — Fort Garry, Fort Edmonton, Fort Langley, and Fort Victoria were Hudson's Bay Company commercial posts, not military bases. "Religious settlements" describes a different pattern of colonial settlement — for instance, early Catholic missions in New France — but does not match these northwest forts. "Mining camps" describes a different settlement type that arose later, especially during gold rushes; the source pairs these northwest cities specifically with the fur trade. Only fur trading posts — the source's exact named origin — matches.
