On June 18, 2026, representatives of Montreal's business community voiced support for a proposal to transform an existing downtown development into the headquarters of the Defence, Security and Resilience Bank. The move is presented as a way to keep the city competitive in the ongoing bid to host the new financial institution.

The plan calls for the repurposing of a central urban project, converting office and retail space into facilities suited to the bank's operational needs. City officials are collaborating with local business leaders to outline the necessary modifications and to ensure the site meets the bank's requirements for security, accessibility and modern infrastructure.

By offering a ready‑made, centrally located location, Montreal hopes to demonstrate its readiness to accommodate the Defence, Security and Resilience Bank and to differentiate itself from other Canadian cities courting the institution. The business community argues that a downtown headquarters would reinforce the city’s role as a hub for financial services and related sectors.

City authorities say the proposal is part of a broader strategy to attract the bank, which is expected to bring specialized expertise in defence, security and resilience financing. If approved, the converted site would become a focal point for the bank's Canadian operations, potentially influencing future investment and development patterns in the downtown core.
