The first settlers arrived near the 1770s and built a flour mill on a township located alongside the Rivière de l'Achigan. The area was located on the northern edges of the first developed lands that were located along both sides of the Saint Lawrence River. In 1787, the Saint-Roch-de-l'Achigan Parish was formed and in 1832, its post office opened, three years after the construction of its first school. In 1845, the parish municipality was established. It was abolished in 1847 when it became part of the County Municipality of Lachenaie, but was reestablished in 1855 as the Parish Municipality of Saint-Roch.^[1]

In 1921, Saint-Roch lost a part of its territory when the Municipality of Saint-Roch-Ouest was formed.^[6] In 1957, it regained its original name when "de-l'Achigan" was added in order to distinguish it from other places named "Saint-Roch". In 2006, it changed statutes and became the Municipality of Saint-Roch-de-l'Achigan.^[1]

The town is accessible via Autoroute 25 which links Laval and Montreal towards the northeastern suburbs including Terrebonne and Mascouche. Since the Olivier-Charbonneau Bridge connecting Montreal and Laval was opened to traffic in 2011, it also has a direct link to the south shore of Montreal and Autoroutes 20 and 40. The municipality is located near the northern terminus of the Autoroute which continues further north via Route 125 towards the Mont-Tremblant Provincial Park north of Saint-Donat and Rawdon.
