Ontario Celebrates First Shipment of Made-in-Ontario Steel for New Coast Guard Icebreaker
Made-in-Ontario steel will be used to build Canada’s newest Coast Guard icebreaker, supporting jobs and strengthening domestic supply chains.
SAULT STE. MARIE — Ontario is marking a major milestone for domestic manufacturing and national security as Algoma Steel ships its first plates of made-in-Ontario steel to Davie in Quebec for construction of the Canadian Coast Guard’s newest icebreaking vessel, the Polar Max.
The shipment represents a significant step in strengthening Canada’s domestic supply chains, boosting interprovincial trade, and reinforcing Ontario’s role as the backbone of the country’s steel and defence manufacturing sectors.
Strengthening Canada’s Defence and Industrial Capacity
A total of 600 net tons of Ontario-made steel plate will be used in the construction of the Polar Max, which is being built under Canada’s National Shipbuilding Strategy and is expected to be delivered in 2030. Once complete, the vessel will be the most powerful conventional heavy icebreaker in the world.
Provincial officials say the shipment underscores Ontario’s ability to supply high-grade materials for nation-building projects at a time of rising global defence investment and ongoing trade pressures from the United States.
Ontario’s steel sector accounts for more than 70 per cent of Canada’s total steelmaking capacity, supporting over 16,000 direct jobs and an estimated 55,000 indirect jobs across the province.

Northern Ontario at the Centre of the Supply Chain
Established in 1901, Algoma Steel is the largest employer in Sault Ste. Marie and the second-largest private-sector employer in Northern Ontario. The company is one of North America’s leading producers of high-quality armour plate, positioning it as a key supplier for defence and marine applications.
Provincial leaders say the shipment highlights the strategic importance of Northern Ontario in Canada’s manufacturing ecosystem, particularly as governments look to reduce reliance on foreign suppliers and keep critical infrastructure spending within Canada.
Building with Canadian Steel
Davie, Canada’s oldest shipbuilder, says the Polar Max project is designed to maximize Canadian industrial participation. The use of Ontario steel ensures skilled jobs are supported across both Ontario and Quebec while strengthening Canada’s shipbuilding and marine defence capabilities.
The project also aligns with Ontario’s Buy Ontario approach, which prioritizes Ontario-made products in public procurement to ensure provincial tax dollars support local workers and businesses.
A Broader Economic Strategy
The steel shipment forms part of Ontario’s broader economic strategy to respond to U.S. tariffs, unlock interprovincial trade, and position the province as a trusted global supplier of advanced manufacturing materials. Ontario officials say continued investment in steel, critical minerals, and advanced manufacturing will be essential to maintaining long-term competitiveness and economic resilience.
With defence and Arctic security playing an increasingly important role in global geopolitics, Ontario’s steel industry is expected to remain a critical contributor to Canada’s national infrastructure and security priorities.
