Canada Launches Competitive Process to Acquire Up to 12 Submarines
The Canadian government has officially launched a competitive process to acquire up to 12 new, conventionally powered, under-ice capable submarines for the Royal Canadian Navy. This procurement initiative, announced by the Department of National Defence (DND) in October 2024, aims to replace the current fleet of four Victoria-class submarines, which are scheduled to reach the end of their operational lifespan in the mid-2030s.
Why is Canada replacing its submarine fleet?
The current Victoria-class submarines, purchased second-hand from the United Kingdom in the 1990s, have faced persistent maintenance challenges and operational limitations. According to the Department of National Defence, these vessels require significant and frequent repairs, which limits their availability for deployment. The federal government intends to transition to a newer, more reliable fleet that can support long-term maritime security, particularly in the Arctic, where melting ice and increased international interest have elevated the need for persistent underwater surveillance.
How will the procurement process work?
The government is currently engaging with international allies and industry partners to identify available submarine designs that meet the Canadian-specific requirements for under-ice operations. The Public Services and Procurement Canada (PSPC) office is leading the engagement, which includes a Request for Information (RFI) sent to various shipyards and nations. Unlike previous procurement efforts, this process emphasizes the need for a fleet that can be sustained for several decades, with a focus on interoperability with NATO allies.

Key Requirements for the New Fleet
- Under-ice capability: The submarines must be equipped to navigate and operate safely beneath Arctic ice packs.
- Extended Range: Enhanced endurance is required to cover Canada’s three-ocean coastline.
- Interoperability: The systems must integrate seamlessly with allied naval forces, particularly those within the Five Eyes and NATO frameworks.
- Domestic Sustainability: The government aims to maximize the involvement of Canadian industry in the long-term maintenance and repair of the vessels.
What is the timeline for delivery?
While the government has not provided a firm delivery date, officials suggest that the goal is to have the first of the new submarines delivered in time to overlap with the retirement of the Victoria-class fleet. This timeline is intended to prevent a “capability gap” that would leave Canada without an underwater defensive presence. The CBC reported that officials are looking at existing designs currently in production by allied nations to expedite the timeline, rather than attempting to design a completely new vessel from scratch.
How does this compare to previous naval acquisitions?
This procurement represents a significant shift in Canadian defense policy. In the past, Canada relied on purchasing used equipment, which often led to higher long-term costs and reduced operational effectiveness. The decision to acquire up to 12 new boats is a departure from the smaller fleet size of four, reflecting a strategic pivot toward a more robust, persistent naval presence. According to the Government of Canada, this investment aligns with the updated defense policy, “Our North, Strong and Free,” which identifies the protection of the Arctic as a primary national security priority.

Projected Impact on Naval Capability
| Feature | Victoria-Class (Current) | New Submarine Fleet (Planned) |
|---|---|---|
| Fleet Size | 4 | Up to 12 |
| Origin | Second-hand (UK) | New construction |
| Primary Role | Coastal defense | Arctic and three-ocean presence |
The procurement remains in the early stages of market engagement. As the process moves forward, the government is expected to release more detailed requirements regarding industrial benefits and specific technical capabilities required by the Royal Canadian Navy.
