Canyon Eaton, Canyon in Rivière-Koksoak, Canada.

Canyon Eaton is a 2.5 km gorge on the Caniapiscau River, between the Rivière du Sable and the Goodwood River in northern Quebec. Its walls rise up to 100 m above the river, and a 30 m waterfall drops within the gorge. Albert Peter Low named it after his assistant surveyor David Eaton.

The canyon formed over millions of years as the Caniapiscau River carved through ancient rock layers of the Canadian Shield. This slow geological process continues to shape the landscape today.

The Naskapi call this stretch of the Caniapiscau River Kwatasiu, meaning "there is a hole or a cave there", a reference to the river's deep entrenchment in the gorge. The name Eaton Canyon honours D. I. V. Eaton, assistant surveyor on Albert Peter Low's 1893–1894 expedition, and was francised to its current form in 1970.

Access to this location requires special transportation arrangements due to its remote position in northern Quebec. It helps to check weather conditions and water levels beforehand, as they can affect your visit.

Albert Peter Low first spelled the name "Eaton Cañon" in his 1893–1894 geological report; the Quebec geography commission made Eaton Canyon official in 1944, and the French form Canyon-Eaton followed in 1970. The Naskapi call the gorge Kwatasiu, meaning "there is a hole or cave there".
