Louis Riel is an opera in three acts composed by Harry Somers, with an English and French libretto (opera text) by Mavor Moore and Jacques Languirand. It tells the story of the legendary Métis political and cultural figure, Louis Riel. Arguably Canada’s most famous opera, it was commissioned by the Floyd S. Chalmers Foundation (now the Chalmers Fund) as part of Canada’s centennial celebrations in 1967. It was initially produced by the Canadian Opera Company (COC) with financial assistance from the Canadian Centennial Commission, the Canada Council and the Province of Ontario Council for the Arts (now the Ontario Arts Council). The opera was reimagined in 2017 by Peter Hinton, who sought to better incorporate Indigenous people and perspectives into the production.
