Canada is modernizing and accelerating defence procurement through the Defence Investment Agency (DIA). By streamlining decisions and centralizing expertise, the Agency is expediting the delivery of mission-critical equipment to the Canadian Armed Forces (CAF).
Canada’s vast coastline and Arctic responsibilities require a modern submarine fleet with long- range, long‑endurance and under-ice capabilities. The future Canadian Patrol Submarine will give the Royal Canadian Navy (RCN) the stealth and persistence needed to protect national security, assert Arctic sovereignty, and support Canada’s international security commitments. The project will also strengthen domestic defence and marine industries and create good-paying jobs across the country.
In August 2025, Canada identified two qualified suppliers for the Canadian Patrol Submarine Project (CPSP): Thyssen Krupp Marine Systems, supported by Germany and Norway, and Hanwha Ocean Co., Ltd., supported by the Republic of Korea. By narrowing the competition to two qualified suppliers, Canada has advanced the procurement timeline by several years, ensuring the RCN receives this capability far earlier. In November 2025, proposal instructions were issued to both firms, with a deadline of March 2, 2026. Both proposals have been received and are currently under review. We expect a decision, as early as summer 2026, as to which of the two qualified suppliers will be chosen as the preferred supplier for contract negotiations.
Input from Canadian industry is vital to shaping a strong and effective sustainment approach for Canada’s future submarine capability. Through this RFI, we are inviting feedback from companies nationwide, spanning defence and non‑traditional sectors, and including businesses of all sizes. Recognizing the scale and long‑term nature of the sustainment work, engaging industry across sectors and of all sizes ensures Canadian businesses are positioned to explore and pursue the opportunities this project may create.
Sustainment activities for the Canadian Patrol Submarine fleet will be conducted in Canada, in or near homeports, supported by a national supply chain. This supports Canada’s Defence Industrial Strategy (DIS), maximizing economic benefits and creating thousands of highly skilled, well‑paid jobs across the country.
Through the DIS, Canada is growing its defence industrial base, with the Agency delivering this approach by engaging industry earlier in the procurement process, fostering innovation, and aligning procurement with long‑term military and industrial priorities. Together, the DIA and the DIS are making generational investments that strengthen Canada’s defence ecosystem, build resilient supply chains, and ensure the CAF has the capabilities it needs to keep Canada safe and sovereign.
