The first settlers began arriving in this area, called "Métis" around 1840.

In 1859, a sector of Métis splitted and became the new municipality of Mac Nider.

The municipality lost signification portions of its territory twice before the end of the 18 century.

In 1931, the original municipality of Saint-Octave-de-Métis changed its name to Grand-Métis, therefore, Saint-Octave-de-Métis-Sud took the current name of Saint-Ocatve-de-Métis.

In 1952, Saint-Octave-de-Métis lost an important portion of its territory for the creation of Les Boules, which as since been merged with Métis-sur-Mer.
