The story
Founded by Pierre Karl Péladeau in 2000.1
In 1983 Québecor purchased the Winnipeg Sun newspaper, which had been independently run. The newspaper was later sold to the Postmedia chain.
In August 2000, Québecor Média bought Vidéotron for CA$4.9 billion. In May 2001, the Canadian Radio-television and Telecommunications Commission (CRTC) approved the transfer of broadcasting licenses from Vidéotron to Québecor Média. Also in 2001, Quebecor Media bought Groupe TVA.
As of June 2018, Québecor Inc. fully owns Québecor Média, while CDP Capital d’Amérique Investissements Inc. (a subsidiary of Caisse de dépôt et placement du Québec, the provincial pension fund) previously owned an 18.9% share. On May 8, 2018, Quebecor had announced its intent to buy out the remainder of the Caisse's stake for $1.69 billion in cash and stock.
