Canada's Niagara Falls was the home to the first hydroelectric power plant, and Canada is one of only eight countries where the majority of its electricity comes from hydroelectric sources. Canada is second in the world in hydroelectric generation, after China.
Because of the high energy usage in Canada, despite the low population, hydroelectric sources are common and very important. There are currently over 650 hydroelectric generation plants and almost one thousand smaller dams where generation takes place. Most of the major plants are in Ontario and Quebec, where the larger rivers merge or are dammed; Niagara Falls, which borders Ontario and New York, is no longer the largest hydroelectric plant in the world, but there are several on the single river and multiple falls, and peak production is about 4.4 gigawatts of power.
Every province in Canada has dozens of hydroelectric plants, and it is vital to Canadian infrastructure that they are maintained and improved. To this end, many of the major sites are owned and operated by the government.
