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 (immediately to the South & East of the falls), Albert Island (to the South), little Coffin Island was just south of Albert Island but is now submerged, Victoria Island and Amelia Island, (which was separated from Victoria Island in 1836 by Government timber slide; now fused to Victoria Island), Philemon Island (to the North) was originally called the Peninsular Village by the Wrights but became an island when the timber slide was built in 1829 Geological Survey of Canada, Multicoloured Geological Map 714, 1901, 1 sheet, https://doi.org/10.4095/107537http://geo-outaouais.blogspot.com/2014/06/; Released: 1901 01 01; GEOSCAN ID: 107537Brault, Lucien.

The area around the falls was once heavily industrialized, especially in the 19th century, driving growth of the surrounding cities.

The damming of the river and the presence of industry have greatly altered the lands surrounding the waterfall, and the fall's appearance. This is especially true in the summer when the Ottawa River is low, and the falls all but disappear because the water is diverted to power stations owned and operated by Portage Power, an affiliate of Hydro Ottawa. Inaccessible for generations, the Falls and hydro facilities are now publicly accessible since the opening of Chaudiere Falls park in 2017, designed by architect Douglas Cardinal. Other properties adjacent to the Falls are slated for development by public and private interests, including an Indigenous welcome centre on Victoria Island, led by the National Capital Commission (NCC) with regional First Nation representatives, and Zibi, a private mixed-use redevelopment project.

Naming The "Chaudière" name was given to the falls by Samuel de Champlain, an early French explorer who noted in a 1613 journal entry that the Indigenous word for the falls was Asticou meaning boiler, but 'Asticou' is now thought to be a misprint as the Algonquin (Anishinaabemowin) word for boiler/cauldron is Akikok, and an Algonquin name for the location is Akikodjiwan. The European name comes from the French Chutes de la Chaudière, meaning "Cauldron Falls", historically translated as "Kettle Falls". The shape of the falls before its development resembled a large kettle, better known to today's English speakers as a cauldron.

William S. Hunter Jr. suggested a different origin for the name in 1855: "The Word Chaudiere is the literal translation into French of the Indian word Kanajo (The Kettle), and is . . . vastly suggestive, for the chasm into which the waters of the Ottawa (Ottawa River) discharge themselves is not unlike a kettle in shape, while the seething and frothing of the surface, in its continual whirl, assists in completing the resemblance," though Hunter himself provides no reference, historical or otherwise, to contradict de Champlain's account of the naming of the falls.

From a 1909 publication, sourced on the Canadian National Museum of History's website: "While waiting thus for their prey to break cover, from up or down the river, they devoted their spare time to various occupations. To the oki, whose thunderous voice was heard in the roar of the falls, they made sacrifices of tobacco; while the Mohawks and Onondagas each gave a name to that cauldron of seething water which is known to us as The Big Kettle. The Mohawks called it Tsitkanajoh, or the Floating Kettle, while the Onondagas named it Katsidagweh niyoh or Chief Council Fire. It is possible that our Big Kettle may be a modified or corrupted translation of the Mohawk term." Vol. XXIII, No. 4: 61-68 & Vol. XXIII, No. 5:92-104

Akikodjiwan is the name given to the falls by some Anishinaabe peoples of this area. For Anishinaabe who gathered and traded along portage routes surrounding the Falls, the waterfall's whirlpool was the bowl of a great peace pipe, and its mists were smoke rising to the Creator.

History

Pre-contact Indigenous trade and travel Prior to European contact and colonization, the area surrounding the Chaudière Falls and islands was a significant meeting place between peoples in the region. Hunting grounds and temporary or semi-permanent settlements dotted the banks of the Ottawa River (Kichi Sipi), as rivers and waterways were used as highways, thanks to innovations such as the canoe. Water levels around the Chaudiere Falls would fluctuate throughout the year, depending on rain and snow melts, and would flood the islands and large swaths of land throughout the watershed. The primary inhabitants of the region were the Algonquin Anishinaabe, who carved complex networks of portage routes to circumvent waterfalls and other natural landmarks.

Exploration and the fur trade

Samuel de Champlain is the first recorded European to label the falls, chaudière, (which the English for a time would call 'Big Kettle') during his 1613 voyage along the Ottawa River. Champlain describes in his journal on June 14, 1613:

"At one place the water falls with such violence upon a rock, that, in the course of time, there has been hollowed out in it a wide and deep basin, so that the water flows round and round there and makes, in the middle, great whirlpools. Hence, the savages call it Asticou, which means kettle. This waterfall makes such a noise that it can be heard for more than two leagues off." "After having carried their canoes to the foot of the falls, they assembled at one place where one of them with a wooden plate takes up a collection, and each one of them places in this plate a piece of tobacco… the plate is placed in the middle of the group, and all dance about it, singing in their fashion; then one of the chiefs makes a speech, pointing out that for a long time they have been accustomed to making this offering, and that by this means they are protected from their enemies…the speaker takes the plate and throws the tobacco into the middle of la chaudière [kettle] and they make a great cry all together." As a medicine plant, the use of tobacco in this Indigenous ceremony signifies that the falls were made a sacred offering.

In the days of the fur trade, the Chaudière Falls were an obstacle along the Ottawa River trade route. Canoes were portaged around the falls at the place now known as Hull.

European colonization

The arrival of Philemon Wright to this area in 1800 marked the start of the development of the city of Hull. In 1827, the region's first bridge, Union Bridge was built close to the falls. When the logging industry began in this area and farther upstream, the falls were again an obstacle for log driving. In 1829, Ruggles Wright (son of Philemon Wright) built the first timber slide, allowing logs and timber rafts to bypass the falls along the north shore, along what is now known as Laurier Street in Gatineau. In 1836, George Buchannan built a slide for cribs between Victoria and Chaudière Islands (on the south side of the river) which later became a major tourist attraction where King Edward VII (then Prince Albert of Wales) in 1860, and the future George V in 1901 both experienced the thrill of "shooting the slides".

Also in the 19th century, some of Canada's largest sawmills were located near the falls. Notable lumber barons in this area were Henry Franklin Bronson and John Rudolphus Booth.

Since then, all the islands and shores at the Chaudière Falls have been developed and the river's flow and drop have long been harnessed to operate paper mills and power stations. In 1910, the ring dam that diverts water to the power stations was built. The E. B. Eddy Company operated a matchmaking business, and a variety of pulp and paper mills, later acquired by Montreal-based Domtar Inc. in 1998. Operations ceased in 2007, the majority of the private properties put up for sale, and transfer to Hydro Ottawa and Hydro-Québec to operate run-of-the-river hydro-electric generating stations at the falls.

Victoria Island

Victoria Island () is located in Ontario between Ottawa and Gatineau on the Ottawa River, where it narrows near the Canadian War Museum at LeBreton Flats. The island is accessible via the Chaudière Bridge, which connects Ottawa's Booth Street to Rue Eddy in Gatineau; the Portage Bridge connecting the two cities passes over. The island had been used by First Nations people for centuries, who named the area Asinabka (Place of Glare Rock). According to archaeological evidence, this site was the centre of convergence for trade and spiritual and cultural exchange. Its position—at the meeting place of three rivers and perched on a rocky point overlooking fast-moving water—gave it special meaning. It is currently part of an area administered by the National Capital Commission.

The island contains an Indigenous business, "Aboriginal Experiences", which offers the history of the First Nations people, a tour, traditional dance, a cafe, and a First Nations craft workshop, all in a wood-pole-fence enclosed area. In 2012, it was selected as the site of Attawapiskat Chief Theresa Spence's protest, due to its proximity to Parliament Hill and its significance to Aboriginal peoples.

Inspired by Algonquin chief and elder William Commanda's vision for Asinabka (the traditional Algonquin Anishinabe name Commanda held for the site), and of a Circle of All Nations and the 8th Fire Prophecy, world-renowned architect Douglas Cardinal has designed plans for an aboriginal healing and international peacekeeping centre on the site. Although there is general consensus for the developments on Victoria Island, while some dispute Commanda's vision for the other islands and falls, his full vision is documented in a presentation he made to the City of Ottawa in 2010 and is also more extensively documented on the Asinabka.com website.

Victoria Island contains the following buildings: Aboriginal Experiences Centre, the Ottawa Electric Railway Company Steam Plant, the Bronson Company Office, No. 4 Generating Station, the Wilson Carbide Mill and Ottawa Hydro Generating Station #2.

On October 3, 2018, the National Capital Commission (NCC) announced that it would be closing down all access to the island, including its businesses, for remediation work from December 2018 to Spring 2020. A second remediation phase is proposed to be undertaken between 2020 and 2025.
