The Ottawa River

The Ottawa River is a major waterway in eastern Ontario and western Quebec, stretching roughly 1,271 kilometers. It begins in the Laurentian Mountains and flows southeast, eventually joining the St. Lawrence River. The river has historical significance for Indigenous peoples and explorers, and today it supports hydroelectric power, recreation, and ecosystems. Its waters provide vital habitat for diverse wildlife and help sustain nearby communities. The Ottawa River also acts as a natural boundary in some areas and plays a key role in regional water management and environmental conservation efforts.
