About 30 kilometers (19 mi) north of Montebello, the municipality is characterized by a relief ranging from 182 meters (597 ft) at Philisson Creek to 381 meters (1,250 ft) at the summit of Mont du Cimetière (Mount Cemetery).

Sparsely populated, inhabited areas are the hamlets of Brookdale and Boileau and also around the Maskinongé Bay and Loup, Champagneur, and Cross Lakes.

They were generally from Ireland and England, or the nearby villages of Calumet and Grenville.

[6] Because the village was better known as Boileau and Ponsonby was limited to purely administrative use, the municipal authorities, with the support of the majority of the population, were granted the official name change from Ponsonby to Boileau in 1993.
