Brossard is a suburban area, located on the south shore of the Saint Lawrence River, opposite the island and city of Montreal. Brossard is subdivided into many smaller sections. These sections are characterized by having street names that all begin with the same letter of the alphabet. The only notable exceptions are few major arteries (such as Taschereau Boulevard and Rome Boulevard) that span across two or more sections.
The residential sections of Brossard are primarily composed of single-family homes, however high-rise condominiums are common near the river. Brossard is the commercial hub of the south shore, most businesses located along Taschereau Boulevard, inside Champlain Mall and Place Portobello or at the brand-new lifestyle centre, Quartier DIX30. A particular segment of Taschereau Boulevard near La Prairie and the Saint-Jacques River is home to an exceptionally large concentration of car dealerships offering most available makes and models.
