Canada’s Big Six banks have announced their commitment to the proposed international Defence, Security and Resilience Bank (DSRB). BMO confirmed its support, becoming the final institution to join RBC, CIBC, Scotiabank, TD and National Bank as partners in the initiative. The DSRB is a proposed multilateral financial institution intended to mobilise capital so NATO members and allied states can finance defence, security and resilience capabilities, supporting allied efforts to expand procurement and industrial capacity.
The question of where the institution will ultimately be headquartered remains unresolved. More than forty countries are being considered to host the bank, though Canada has emerged as a credible contender. The host country is expected to be announced in the coming months, with the chosen city to follow by year’s end.
Establishing the bank in Canada would position the country as a financial anchor for allied defence investment and reinforce its role within NATO’s evolving security architecture. Competition has therefore intensified among Canadian cities seeking to host the institution. Montreal, Ottawa, Vancouver and Toronto have each submitted bids supported by coalitions of municipal authorities, provincial governments and private sector actors, with Montreal and Toronto emerging as leading contenders.
The proposal reflects a broader shift in how democratic allies are financing defence. Many governments face pressure to expand military spending while operating under fiscal constraints that make rapid increases in defence budgets politically difficult. The DSRB is designed to address this tension by creating a multilateral financial mechanism capable of supporting large-scale defence procurement and industrial investment.
Participating governments would contribute capital to the institution, which would then issue highly rated bonds on international capital markets. By leveraging the combined credit strength of multiple states, the bank could raise substantial financing on global markets and lend it for defence procurement, industrial expansion and resilience infrastructure at lower borrowing costs than many governments could secure independently. Guarantees could also encourage commercial lenders to extend credit across the defence industrial supply chain. In practice, the model converts collective political commitment into expanded financial capacity for allied procurement.
Although frequently discussed in connection with NATO, the DSRB would operate as an independent multilateral financial institution owned by participating governments. Its mandate would nonetheless align closely with allied defence priorities, directing financing primarily toward NATO members and partner states seeking to strengthen military capability and resilience. This could include major joint procurement initiatives such as next generation aircraft, missile defence systems, and large scale industrial expansion across the defence supply chain, particularly benefiting allies with more limited fiscal capacity seeking to accelerate rearmament. This would be particularly relevant for Central and Eastern European allies still reliant on aging Soviet-era systems and requiring large-scale modernization, including jets, armored vehicles, and transport capabilities. As Rob Murray, chief executive officer of the DSRB, has noted, “many Central and Eastern European nations still grapple with the legacy of the Cold War, reliant on aging Soviet-era equipment to defend themselves.” The bank could also extend financing to partner states beyond NATO, including Indo-Pacific allies, enabling joint procurement, leasing arrangements, and supply chain integration that strengthen interoperability and deepen defence partnerships across regions.
This financial model has direct implications for how allies expand defence investment. By pooling capital and accessing global bond markets collectively, participating states could generate significantly greater funding for procurement and defence production than individual national budgets alone might allow. The mechanism could also allow smaller allies with more limited fiscal capacity to contribute more meaningfully to collective defence while spreading financial risk across participating governments. At the same time, the benefits of pooled financing are not evenly distributed. Canada’s debt is already rated AAA by S&P Global, and Canadian bond yields are already among the lowest in the G20, meaning the marginal financial advantage of borrowing through such a mechanism may be limited compared to other participating states.
For Canada, hosting the bank would carry both economic and geopolitical significance. The institution’s establishment is projected to generate roughly 3,500 jobs in defence finance, international operations and specialised research and analysis. Support from Canada’s major banks also strengthens the country’s credibility as a location capable of anchoring large-scale bond issuance and attracting international capital. However, any preferential borrowing terms generated through pooled financing would likely depend on contributions from stronger-credit members, raising questions about the extent to which Canada itself materially benefits from the financial structure, and whether it risks disproportionately underwriting advantages for other allies.
The strategic dimension is equally important. Canada remains below the alliance’s two percent defence spending benchmark and has faced sustained pressure from allies to increase its contribution to collective defence. Prime Minister Mark Carney acknowledged that Canada achieved this threshold in March and has committed to raising defence spending to five percent of GDP by 2035. In this context, the DSRB could provide governments with access to long term financing that supports procurement and industrial expansion while easing short term fiscal pressure.
Hosting the institution would also place Canada at the centre of an emerging financial network for allied security cooperation. Countries that host major multilateral institutions often gain diplomatic and policy influence as governments, investors and international organisations cluster around them. A bank dedicated to financing allied defence production and resilience would therefore expand Canada’s role within the institutional landscape that supports NATO and its partners. As one analysis notes, a leading role at a new multilateral institution would give us an “influential seat at the table for global defence co-ordination”, allowing Canada to shape priorities and strengthen alliances through financial leadership.
More broadly, the DSRB reflects a growing effort among democratic allies to mobilise financial markets in support of defence procurement and industrial expansion. If implemented successfully, it could substantially increase the resources available for allied defence investment. Should Canada ultimately host the institution, the country would not only benefit economically but also occupy a central position in this evolving system of allied defence finance.
