In 1980, Hydro-Québec oversaw the installation of the LG-2 Dam on the La Grande River in James Bay. Thanks to this dam and many others, Quebec is one of the largest producers of electricity in North America. The creation of hydroelectric dams is possible because of the territory’s relief. 

The creation of the LG-2 Dam on the La Grande River in James Bay had large political impacts. Cree, Inuit and Naskapi communities were worried about the impacts the dam would have on the land, animals, and their ways of life. Representatives from these communities fought to have their concerns heard. Eventually, this led to the negotiation of the James Bay and Northern Quebec Agreement and the Northeastern Quebec Agreement. Even today, these agreements have big political implications on Indigenous autonomy and the obligations of the Quebec government. 


The beginning of the century

The first hydroelectric dams were built by private companies on the rivers of southern Quebec, such as the Saint-Maurice River. At the beginning of the century, large private companies like the Shawinigan Water & Power Co. and Montreal Light Heat and Power controlled the production and distribution of electricity

The creation of Hydro-Québec

During the first half of the century, the Quebec government had left the control of the production of electricity in the hands of private companies. However, in 1944, it decided to intervene by buying the Montreal Light Heat and Power to create Hydro-Québec. The Quebec government did this because electricity prices were very high, especially in Montreal. Hydro-Québec made a commitment to provide electricity at a reasonable price to all consumers in the region of Montreal.

During the years following World War II, power consumption increased quickly in Quebec, particularly because of the large number of electrical appliances found in homes. The government also passed a law to promote rural electrification. In 1945, only 19% of farms in Quebec had access to electricity. In 1955, 90% of them had access.


In 1962, the Quebec government became more involved in hydroelectric production by nationalizing electricity, meaning they bought all private electricity companies in Quebec to merge them with Hydro-Québec. The corporation conducted large-scale hydroelectric projects such as the Manicouagan River and the La Grande River.
