Settlement in this area by Europeans began in the mid-nineteenth century. By 1863, there was a population of 140 people, most of Irish origin and almost all Catholics. In 1864, the Egan Township was proclaimed, named in memory of
John Egan (1811-1857), an Irish immigrant, owner of large logging concessions in the Outaouais, and holder of several political offices. In 1881, the Municipality Township of Egan was formed, with Patrick Moore as first mayor who served until 1902. In 1920, Egan Township was split up into the municipalities of Egan-Sud, Bois-Franc, and Montcerf (now Montcerf-Lytton). The first mayor of Egan-Sud was James Millar. ==Demographics==
