Northern Transformer's Innisfil expansion highlights electrical safety, supply chain resilience
Northern Transformer Corporation (NTC) is investing $207 million to build a new manufacturing facility in Innisfil, Ontario, creating 151 jobs and expanding the province’s capacity to produce high-voltage power transformers. The project, backed by $10.5 million in provincial funding, also brings heightened attention to the safety planning required for large-scale electrical manufacturing.
“This investment not only boosts our production capacity and technical capabilities, but also drives job creation, innovation and supply chain growth in the region,” said Alexei Miecznikowski, president and CEO of NTC.
The facility will produce and test transformers with power ratings up to 500kV and 750MVA, used in sectors such as steel manufacturing, data centres, and mining. High-voltage manufacturing environments demand strict compliance with Ontario’s Occupational Health and Safety Act (OHSA), especially in areas such as arc flash prevention, lockout/tagout, and hazardous energy control.
While specific safety measures for the new site have not yet been released, industry standards dictate that operations involving transformer oil, electrical testing, and energized equipment require robust systems for worker protection, emergency response, and environmental compliance.
Domestic supply chains, local risk controls
NTC’s new product lines will source wiring, insulation, and electrical steel from Ontario-based suppliers—supporting the province’s push to localize critical infrastructure. This move reinforces the need for coordinated safety practices not only within the facility, but also across the broader supply chain.
“Northern Transformer’s investment is an important win for Innisfil and the province. It builds capacity in critical electric grid equipment, creates good jobs and opens new opportunities for Ontario suppliers,” said Khawar Nasim, CEO of Invest Ontario.
Founded in Ontario in 1981, NTC already operates a facility in Maple, where it produces smaller-capacity transformers and employs 150 workers. The Innisfil expansion marks its entry into large transformer manufacturing, adding new technical and regulatory complexity.
Workforce and regulatory context
The expansion is expected to support Ontario’s Integrated Energy Plan and help modernize the province’s electricity grid. Provincial officials emphasize that these kinds of industrial projects also require close attention to safety standards.
“With power demand rising amid a backdrop of global uncertainty, our government is doubling down on Ontario-made technology, materials, and workers,” said Stephen Lecce, Minister of Energy and Mines.
As hiring begins, health and safety professionals will be watching for the development of competency-based training programs and compliance with evolving legislation, including recent changes under Ontario’s Working for Workers Acts. Joint Health and Safety Committees (JHSCs) and sector-specific safety associations may play a key role in supporting safe operations during both construction and production.
“At Hydro One we continue to build a grid to meet the needs of the future and Northern Transformer will play a key role in our success,” said Lindsay Zylstra, vice president of Supply Chain and Fleet Services. “Now more than ever, we must focus on investing in homegrown businesses to build a strong, secure and self-reliant supply chain here at home.”
What’s next?
Construction timelines and operational dates have not yet been announced. However, for safety professionals, the Innisfil project underscores a growing demand for advanced safety planning in Canada’s energy and manufacturing sectors — especially as the province invests in high-risk, high-reward industrial infrastructure.
