The Chaudière Falls, also known as the Kana:tso or Akikodjiwan Falls, are a set of cascades and waterfall in the centre of the Ottawa-Gatineau metropolitan area in Canada where the Ottawa River narrows between a rocky escarpment on both sides of the river. The location is just west of the Chaudière Bridge and Booth-Eddy streets corridor, northwest of the Canadian War Museum at LeBreton Flats and adjacent to the historic industrial E. B. Eddy complex. The islands surrounding the Chaudière Falls, counter-clockwise, are Chaudière Island, Albert Island, little Coffin Island was just south of Albert Island but is now submerged, Victoria Island and Amelia Island,, Philemon Island was originally called the Peninsular Village by the Wrights but became an island when the timber slide was built in 1829 it is now fused to south shore of City of Gatineau, and Russell Island, now submerged, was at the head of the Falls before the Ring dam was built. The falls are about 60 metres (200 ft) wide and drop 15 metres (49 ft). The area around the falls was once heavily industrialized, especially in the 19th century, driving growth of the surrounding cities.
