Torstar Corporation is a Canadian mass media company which primarily publishes daily and community newspapers. In addition to the Toronto Star, its flagship and namesake, Torstar also publishes daily newspapers in Hamilton, Peterborough, Niagara Region, and Waterloo Region. The corporation was initially established in 1958 to take over operations of the Star from the Atkinson Foundation after a provincial law banned charitable organizations from owning for-profit entities. From 1958 to 2020, the class A shares of Torstar were held by the families of the original Atkinson Foundation trustees. The private investment firm NordStar Capital LP, owned by Jordan Bitove and Paul Rivett, officially acquired Torstar on August 5, 2020.
