Final answer:
The Canadian city traversed by the Don and Humber Rivers is Toronto, with both rivers playing a key role in the city's development and ecology.
Step-by-step explanation:
The Canadian city that is traversed by the Don and Humber Rivers is Toronto. These two rivers flow through the city and are significant parts of Toronto's landscape and history. The Don River winds its way southwards across the city, emptying into Lake Ontario, while the Humber River also travels towards Lake Ontario, defining part of the city's western boundary. Both rivers have been important to the growth and development of Toronto, providing natural resources and influencing settlement patterns.
The presence of these rivers in a densely populated urban area like Toronto offers both recreational opportunities and ecological challenges. Their watersheds are carefully managed to balance the needs of urbanization with environmental preservation and flood control.
