New Partnership Targets Submarine MRO Development for Canada’s Submarine Project

Why It Matters

Domestic MRO capability reduces dependence on foreign yards, bolsters operational readiness, and deepens Canadian industrial participation in sovereign defence assets.

Key Takeaways

• Hanwha and PCL sign teaming agreement for Canadian submarine MRO.
• Facilities planned for Esquimalt, BC and Halifax, NS coasts.
• Hanwha brings submarine design and sustainment expertise.
• PCL contributes large‑scale construction and defence project experience.
• Partnership enhances Canada‑led sovereign submarine capability.

Pulse Analysis

Canada’s ambitious Patrol Submarine Project (CPSP) hinges not only on acquiring new vessels but also on sustaining them over decades. Submarine maintenance, repair and overhaul (MRO) facilities are critical for operational availability, especially given the harsh Atlantic and Pacific environments where the fleet will operate. By establishing dedicated MRO hubs on both coasts, Canada aims to avoid costly overseas dry‑dock cycles, shorten turnaround times, and retain strategic control over its underwater assets.

The newly announced teaming agreement pairs Hanwha Ocean’s deep naval engineering pedigree with PCL Construction’s proven track record delivering large defence infrastructure across Canada. Hanwha’s recent 16‑month overhaul of the Republic of Korea Navy’s Type‑214 submarine demonstrates its capability to manage complex lifecycle programs, while PCL’s experience with the Department of National Defence ensures compliance with Canadian standards and procurement practices. Together, they will coordinate design, engineering, supply‑chain logistics and construction to deliver state‑of‑the‑art MRO facilities that meet the specific requirements of the upcoming Canadian‑built submarines.

Beyond the immediate project, the collaboration signals a broader shift toward a Canada‑centric defence industrial base. By involving domestic firms in critical support infrastructure, the government reduces reliance on foreign shipyards, safeguards sensitive technology, and creates high‑skill jobs in coastal regions. The partnership also positions Canada to offer MRO services to allied navies in the future, potentially turning the new facilities into exportable capabilities. As the CPSP moves toward full operational status, this integrated approach to sustainment will be a cornerstone of Canada’s maritime sovereignty and long‑term defence strategy.
