Construction work begins at St. Thomas EV battery plant
PowerCo Canada has officially started construction work on its St. Thomas gigafactory project, celebrating the start of construction on three major buildings.
The work, which began on October 28, officially launches development of what will become Canada’s largest EV battery plant, with initial production targeted for 2027.
“Today marks a big milestone for PowerCo Canada, as we officially mark the beginning of construction on our third and largest EV gigafactory worldwide”, said Frank Blome, CEO of PowerCo SE. “Electric vehicles are the future of the global automotive sector, and we’re proud to spearhead such a significant investment, while positioning Canada at the forefront of innovative EV battery production. We aim to build a global battery champion with a strong footprint in Europe and North America.”
Magil Construction Canada Inc., is leading the foundational work for three major buildings at the site, involving over 500,000 square feet of formwork, more than 32,000 cubic meters of concrete, and approximately 4,850 metric tonnes of rebar. Steel erection by Canadian partner Steelcon, is also set to commence in the coming weeks.
“Seeing concrete being poured is an incredibly exciting moment for Magil Construction Canada and the entire project team,” said Paul Henke, President of Magil Construction Canada Inc. “We are proud to be PowerCo’s Canadian partner, bringing our expertise and skilled local talent to build this state-of-the art facility. This project is a testament to the talent here at home and we are proud to support this generational project.”
Once complete, the St. Thomas gigafactory will bring PowerCo’s advanced Unified Cell battery technology to Canada, supporting a more resilient domestic supply chain and further solidifying Canada’s position as a global EV manufacturing hub.
Recruitment is also well underway, with more than 100 applications received since the launch of a major campaign across Southwestern Ontario. The campaign includes transit, billboard and social media ads aimed at attracting top-tier local talent for the thousands of jobs the plant will create.
With an investment of up to $7 billion, the St. Thomas gigafactory is PowerCo’s third and largest project globally.
