Answer: grew into towns and cities.
Explanation:
Trading posts were established along the frontier to better take advantage of the fur trade. At first these were simply trading posts but then they grew into settlements overtime.

These activities and more as well as the fall in fur trade and the rise in agriculture led to these trading posts becoming permanent settlements that grew into towns and cities.
