Canada Taps German Submarines for Biggest Defence Deal in History

Canada has picked Germany's ThyssenKrupp Marine Systems to build its next fleet of submarines, in what's expected to become the largest defence procurement in the country's history. Prime Minister Mark Carney called the partnership the "best platform" for the Royal Canadian Navy's future.

A historic deal takes shape

Canada has chosen a new partner to build the next generation of its submarine fleet — and it's not who many expected. Prime Minister Mark Carney announced that German shipbuilder ThyssenKrupp Marine Systems has been selected as the country's preferred bidder for a multibillion-dollar program that could end up being the biggest defence contract in Canadian history.

The decision caps months of speculation over which nation would win the contract, with Norway and South Korea also in the running. In the end, Carney said Germany offered the combination Canada was looking for, describing ThyssenKrupp as the "best platform and partnership" for a program that will reshape the Royal Canadian Navy for decades to come.

Why this matters

Canada's current fleet of Victoria-class submarines is aging out, and defence planners have been warning for years that the country needs a modern replacement to patrol its coastlines — including the increasingly contested waters of the Arctic. Submarines are seen as a key tool for asserting sovereignty in the North, where climate change is opening new shipping routes and drawing interest from other global powers.

The scale of the program is what's turning heads. Multiple submarines are expected to be built over the coming years, with a price tag that could run into the tens of billions of dollars once construction, maintenance, and lifecycle costs are factored in. That would make it larger than any previous Canadian defence purchase, including recent fighter jet and warship programs.

What's next

While ThyssenKrupp has been named the preferred choice, a final contract still needs to be negotiated and signed — a process that typically takes time given the complexity of submarine construction and the need for technology transfer, domestic industrial benefits, and long-term servicing arrangements. Governments often use these massive procurements to secure commitments around Canadian jobs and shipyard involvement, so expect more details in the coming months on how much of the work will happen on home soil.

The announcement is also a signal of where Carney's government wants to position Canada on defence spending more broadly, as NATO allies face pressure to boost military budgets amid global instability. A submarine program of this size suggests Ottawa is planning for a navy that can operate independently across multiple oceans well into the middle of the century.

For now, the deal marks a major milestone in a procurement saga that has played out over several years, and it sets the stage for one of the most significant industrial and military partnerships Canada has entered into with an ally.
