It was founded in 1836 by people who came from Ste-Anne-de-la-Pérade following to the east along the Sainte-Anne.

The name of Saint-Casimir was given in honour of Mr. Casimir Déry, a notary who paid for the construction of the church, which is in the top 10 of the most beautiful churches in the province of Québec. In turn, the church, and the town, is named after Saint Casimir, a patron saint of Poland, Lithuania, and youth.

Two provincial numbered roads go through St-Casimir: Route 354 (east-west - from Ste-Anne de la Pérade to St-Raymond) and Route 363 (south-north - from Deschambault to Lac-aux-Sables). Both roads lead to Autoroute 40, the Montreal-Québec City link on the north shore.

Five rivers run in Saint-Casimir: Sainte-Anne, Niagarette, Petite Niagarette, Blanche and Noire.

Saint-Casimir is also the home to a cavern, the "Trou du Diable" ("Devil's Hole"). It is the second longest cave in Québec, at 980 metres (3,220 ft). It was formed by the former tributary of the Sainte-Anne River, which left behind a stream. Lots of tourists come to visit and go through it every summer.

It is the place where poet Alain Grandbois was born in 1900.

On the morning of March 23, 1997, five members of the Order of the Solar Temple took their own lives in Saint-Casimir. A small house exploded into flames, leaving behind five charred bodies for the police to pull from the rubble. Three teenagers—13, 14 and 16, the children of one of the couples that died in the fire —- are discovered in a shed behind the house, alive but heavily drugged.

In the summer of 1973, a wave on the Niagarette devastated a small area, where it joins the Sainte-Anne River. A few houses were destroyed by the powerful water wave, due to strong rain, and debris that blocked the small river for a few hours.
