Ontario Energy Expansion Drives $30 Million Hitachi Energy Investment in Stoney Creek
Ontario Energy Expansion Powers New Manufacturing Growth
STONEY CREEK — Ontario’s growing energy infrastructure strategy is attracting major private-sector investment, with Hitachi Energy confirming a $30 million upgrade and expansion of its newly purchased Stoney Creek facility. The project will support 155 existing jobs and create 30 new positions, reinforcing Ontario’s domestic manufacturing capacity as electricity demand climbs across the province.
The announcement comes as Ontario accelerates the largest energy system buildout in North America, backed by the province’s new Integrated Energy Plan and its commitment to construct up to 1,500 kilometres of new transmission lines.
Critical Transformer Expertise Strengthens Ontario’s Energy Security
Hitachi Energy’s Stoney Creek facility is Canada’s only site dedicated to upgrading and extending the life of medium and large transformers up to 765 kV—equipment essential to delivering reliable power across the grid.
The plant’s specialized refurbishment capabilities are rare in North America and significantly reduce dependency on international suppliers. According to government officials, strengthening domestic transformer servicing is key to ensuring utilities can maintain stable operations, respond to infrastructure needs quickly and avoid costly delays in supply chains.

Hitachi Energy will also acquire a new service facility in Cambridge, which will serve as the company’s national hub for field service operations, allowing faster on-site support for utilities and large industrial customers across Canada.
Local Economic Impact and Provincial Energy Strategy Alignment
Ontario officials emphasized that the investment advances the province’s long-term goals: supporting economic growth, boosting energy reliability and reinforcing made-in-Ontario supply chains.
The Stoney Creek and Cambridge expansions come at a time when global supply chain pressures have highlighted the risks of relying on foreign sources for key grid components. Limited national capacity to service large transformer units has historically led to longer turnaround times, higher project costs and increased vulnerability for utilities and industries.
Strengthening domestic capacity now positions Ontario to better meet rising electricity demand driven by population growth, industrial expansion and a clean-energy transition.
Community and Industry Support
Local leaders and industry associations—including the Ontario Energy Association, Hamilton Chamber of Commerce and Canadian Manufacturers & Exporters—welcomed the investment as a boost to good-paying jobs, regional competitiveness and Ontario’s long-term grid resilience.
The announcement also aligns with the provincial government’s focus on supporting a robust energy supply chain that enables major industries—including manufacturing, mining, agriculture and nuclear energy—to operate with confidence as demand accelerates.
Hitachi Energy employs more than 1,000 workers nationwide and is positioned to play an expanded role in Ontario’s energy infrastructure development.
Environmental and Economic Benefits
Refurbishing transformers can reduce emissions by up to 70 per cent compared to manufacturing new units, offering both economic and environmental advantages.
A single 765 kV transformer—the largest class serviced at Stoney Creek—can supply enough electricity to power a city of approximately 250,000 people.
Ontario’s energy transmission network currently includes more than 30,000 kilometres of high-voltage lines connecting generating stations to communities, industries and homes across the province.
