The Financial Post started publication in 1907 by John Bayne Maclean.

[2] It was a weekly publication, and one of the core assets of Maclean's media business, which eventually became Maclean-Hunter.

[2] The paper was purchased by Sun Media in 1987, and expanded into a daily tabloid on February 1, 1988, and added newspaper home delivery in 1990, with a reformatted Financial Post Magazine following shortly after.

In 1998, Sun Media sold the Financial Post to Hollinger, whose CEO Conrad Black had been seeking a way to establish a national newspaper.

[3] Sun Media acquired the Kitchener-Waterloo Record, the Guelph Mercury, the Hamilton Spectator and the Cambridge Reporter from Hollinger in exchange,[3] but has since sold all four papers.
