Economic and Financial Implications
While the purchase of 12 submarines is estimated to cost between 20 billion and 24 billion Canadian dollars, the full lifecycle cost—including operation, maintenance, and repairs—could exceed 100 billion dollars over two decades.
TKMS previously announced in July 2026 that its offer included potential investments in Canada estimated at approximately 86 billion Canadian dollars, with total expected economic activity reaching about 167 billion dollars. These figures are economic expectations and do not represent guaranteed or already injected funds.
Proposed economic projects linked to the German offer include:
- A large carbon capture facility in Alberta using TKMS technology.
- The modernization and expansion of the Port of Churchill in Manitoba to support the export of critical minerals and liquefied natural gas.
- The establishment of a factory in Canada to produce heavy torpedoes.
- Joint development and testing of hypersonic missile technologies.
- Specialized submarine maintenance facilities on Canada's eastern and western coasts.
Dave Perry, president of the Canadian Global Affairs Institute, noted that dividing the order could result in losing economies of scale and reducing the scale of promised economic benefits.
