Bank of Montreal is putting one of Canada’s largest financial institutions behind a decade-long push to finance the industries Ottawa increasingly views as essential to economic security. BMO announced on September 11 that it intends to mobilize up to $70 billion in new capital over 10 years across transportation, electricity, pipelines, mining and critical minerals, artificial-intelligence computing, defence and security, and oil and gas.
The commitment arrives as Canada attempts to turn a growing collection of ports, mines, power lines, energy projects and technology infrastructure into investable projects capable of attracting private money at much greater scale. It also comes immediately before the September 14–15 Canada Investment Summit in Toronto, where governments and institutional investors are trying to accelerate a much broader national investment drive.
The $70 Billion Is a Financing Commitment, Not One Giant Cheque
The most important detail in BMO’s announcement is the word “mobilize.” The bank is not promising to take $70 billion from its own balance sheet and directly build roads, mines or power stations. Instead, BMO says the new capital could be assembled through bank financing, debt-capital-markets transactions and the raising of public equity. That gives the initiative a much wider reach because the bank can act as lender, arranger and capital-markets intermediary depending on what an individual project requires.
The 10-year horizon is equally important. BMO described the figure as “up to” $70 billion, meaning it is a maximum commitment rather than money that has already been deployed or contractually assigned. No amounts were announced for individual sectors or named projects. The distinction matters because major infrastructure financing normally depends on permits, construction schedules, customers, revenue assumptions and other conditions being settled before large sums can actually move. BMO is effectively signalling that it wants to be part of that financing pipeline as Canadian projects reach investable stages.
Transportation Infrastructure Sits Near the Centre of the Plan
Roads, airports and terminals are explicitly included in BMO’s target sectors, putting transportation alongside energy and mining in the bank’s definition of strategic infrastructure. That matches Ottawa’s own effort to expand the physical corridors Canadian producers use to reach international buyers. The federal government launched a $5-billion Trade Diversification Corridors Fund in 2026, alongside a $1-billion Arctic Infrastructure Fund, with investments aimed at ports, railways, airports, highways and other infrastructure that can increase access to markets outside the United States.
Recent projects show how much capital those systems can absorb. The CANXPORT facility at Ridley Island in British Columbia, supported by nearly $50 million through the National Trade Corridors Fund, was designed to handle at least 400,000 shipping containers annually and potentially as many as 750,000. For exporters, projects like that are more than concrete and rail track: they determine how quickly Canadian forestry, agricultural and manufactured products can reach ships. BMO’s commitment potentially adds another financing channel when larger transportation proposals need commercial debt or capital-market funding.
Critical Minerals Bring Mining and Infrastructure Together
Mining and critical minerals form another major pillar of the commitment. Canada has spent several years trying to move beyond simply having mineral deposits toward building complete domestic supply chains that include extraction, processing, transportation and manufacturing. The federal Critical Minerals Strategy identifies the sector as important to economic growth, advanced technology, energy systems and national security, while Ottawa has increasingly emphasized minerals that can serve both civilian and defence supply chains.
Financing remains a major piece of that challenge. In March 2026, the federal government announced more than $3.6 billion in new programs and investments related to critical minerals, including a $1.5-billion First and Last Mile Fund intended to support infrastructure needed around new mines. Projects can require transmission lines, upgraded roads, processing plants and other assets long before a mine reaches full production. In British Columbia, for example, federal programs have supported transmission upgrades connected with the Red Chris copper expansion and infrastructure planning for the Wicheeda rare-earth project. BMO’s initiative could complement such public support if commercially viable projects require debt, equity or capital-market access.
Canada’s Expanding Power Grid Creates Another Huge Financing Need
BMO also singled out electricity generation, transmission and distribution, an area where Canada is preparing for substantially higher demand. The federal National Electricity Strategy is built around an ambition to double the capacity of the Canadian grid by 2050. That means building generating assets as well as the transmission lines and interconnections needed to deliver power to growing cities, industrial developments, mines, data centres and other major users.
The North Coast Transmission Line in British Columbia illustrates the scale and complexity involved. Canada and British Columbia committed $3.9 billion toward the first two phases, while the Canada Infrastructure Bank had already closed a $139.5-million loan supporting pre-construction work. The line is intended to more than double the availability of electricity along parts of the West Coast and support industrial development, including critical-mineral projects. Elsewhere, proposed and announced hydroelectric, nuclear and interprovincial transmission investments run into the billions. In that environment, BMO is positioning itself for a market in which public funding, utility spending and private financing may increasingly have to work together to move projects from planning to construction.
Pipelines and Oil and Gas Remain Part of the Strategic Picture
BMO’s commitment is notably broader than a clean-energy financing program. It specifically includes energy infrastructure such as pipelines as well as the oil-and-gas sector itself. The bank said its estimate of potential capital demand reflects, among other things, initiatives connected with the agreement involving the federal government, Alberta and the Oil Sands Alliance. That puts conventional energy development alongside electricity, minerals, AI and defence rather than treating the sectors as separate economic agendas.
The prospective financing requirements can be enormous. Alberta’s proposed West Coast Oil Pipeline, now being considered through the federal Major Projects Office process, is envisioned as roughly 1,250 kilometres long and capable of moving one million barrels of crude per day from the Edmonton region toward a British Columbia export terminal. It remains at an early stage and its route has not been finalized. Separately, construction began in 2026 on Enbridge’s approximately $4-billion Sunrise Expansion of its Westcoast natural-gas system, designed to add up to 300 million cubic feet per day of capacity. BMO has not said that its new commitment finances either project specifically.
AI Computing and Defence Show How the Definition of Infrastructure Is Changing
Some of BMO’s target sectors would barely have appeared beside highways and pipelines in a traditional infrastructure plan. AI computing and defence and security are now explicitly included, reflecting how governments increasingly treat computing capacity, technological sovereignty and industrial supply chains as strategic assets. Canada opened applications in April for its AI Sovereign Compute Infrastructure Program, intended to support large-scale Canadian-based supercomputing capacity for researchers, companies and institutions.
Defence is undergoing a similar shift. Canada’s 2026 Defence Industrial Strategy includes a $4-billion Business Development Bank of Canada platform aimed at loans, venture capital and advisory support for smaller defence-sector businesses. By July, the government said BDC had already supported 130 small and medium-sized companies through its defence work, while Export Development Canada had provided roughly $2 billion in financing and insurance support to defence and security firms since expanding its activity in the sector. Those initiatives illustrate why commercial banks see potential demand extending far beyond traditional military contractors. Suppliers of components, computing systems, aerospace technology, communications equipment and dual-use technologies may all require growth capital.
BMO’s Announcement Fits Directly Into Ottawa’s Major-Projects Push
The timing is difficult to separate from Canada’s broader effort to make more large projects financeable. BMO explicitly said its commitment reflects expected demand from initiatives submitted to the Major Projects Office, as well as the National Electricity Strategy, sovereign-AI projects and other strategic sectors. The Major Projects Office currently describes a pipeline of 18 referred projects and nine transformative strategies, representing about $192 billion in new investment and the potential to support roughly $500 billion in future private-sector investment.
That pipeline includes transportation, mining, electricity and energy proposals—the same broad categories BMO is targeting. Ottawa has also established a longer-term goal of catalysing $1 trillion in total Canadian investment over five years. The Canada Investment Summit scheduled for September 14 and 15 in Toronto is intended to bring international investors, Canadian executives and public-sector representatives together around those opportunities. BMO announced its financing initiative just days before that gathering. For Ottawa, commitments from large domestic financial institutions can help demonstrate that the government is not expecting taxpayers alone to finance every project it wants accelerated.
The Bigger Test Will Be How Much Capital Actually Reaches Projects
BMO has the scale to make the commitment consequential. The bank reported total assets of about $1.5 trillion as of July 31, 2026. It says it authorized nearly $300 billion in lending to more than 270,000 Canadian businesses and organizations in 2025 and that more than $133 billion was invested in Canada through BMO-managed mutual funds and exchange-traded funds. The new initiative therefore builds on an already large financing platform rather than creating one from scratch.
BMO is also not acting alone. Sun Life announced a separate $5-billion Canadian infrastructure commitment over five years, while Power Sustainable said it plans to invest and mobilize more than $10 billion in Canadian projects and companies over the same period. Still, headline commitments and completed projects are different things. BMO itself classifies the $70-billion plan as forward-looking and says outcomes can be affected by economic conditions, interest rates, markets, government initiatives and regulatory developments. The real measure of the announcement will be whether enough proposed mines, terminals, power systems, pipelines, data centres and defence businesses become commercially viable enough for that capital to move.
