Get KOHO Free — Code 45ET55JSYAThe Couronne Sud (South Crown) refers to the outer ring of Montreal suburbs located south of Longueuil and Brossard, primarily in the Montérégie administrative region. These communities make up the broader South Shore beyond the immediate Longueuil agglomeration.
Key Couronne Sud communities include:
The Couronne Sud is characterized by a mix of established suburban communities close to Montreal and more rural agricultural areas farther from the island. Banking infrastructure is strong in larger centres and more limited in smaller communities.
Desjardins is the most important financial institution across the Couronne Sud. In many communities, the local Caisse Desjardins is the only bank branch in town. For mortgages, personal banking, agricultural financing, and business services, Desjardins is the go-to throughout the Montérégie region. Unlimited AMF deposit insurance and a strong community focus.
KOHO is particularly practical in the Couronne Sud where smaller communities may not have a full range of bank branches. Full French support, zero monthly fees, cash back on everyday spending — everything accessible from your phone. Use code 45ET55JSYA to open free.

The South Shore (Rive-Sud) typically refers to the immediate suburbs across from Montreal — Longueuil, Brossard, Saint-Lambert. The Couronne Sud is the outer ring further south — Boucherville, Varennes, Saint-Hyacinthe. Both share the no-surtax welcome tax advantage.
In smaller municipalities, branch access is more limited. Desjardins is usually present in even small communities. For other banking needs, digital banks like KOHO and EQ Bank are the practical solution for residents without a full bank branch nearby.
The Couronne Sud has significant agricultural land, and agricultural property purchases have their own financing rules in Quebec. Desjardins and National Bank have agricultural financing expertise important for buyers of farm properties.
No fees, full French support — KOHO works from Boucherville to Saint-Hyacinthe.
