A small Northern Ontario community is set to play a major role in North America’s clean energy future.

Electra Battery Materials is moving forward with plans to build North America’s first battery-grade cobalt refinery in Cobalt, Ont., with commercial operations expected to begin by the end of 2027. Once operational, the facility will produce up to 6,500 tonnes of cobalt sulfate annually—enough to supply approximately one million electric vehicle batteries each year.

A milestone for North America’s battery industry

The refinery will be the first of its kind in North America and only the second battery-grade cobalt refinery outside China. The project marks a significant step toward strengthening the continent’s critical mineral supply chain as demand for electric vehicles, energy storage systems and advanced technologies continues to grow.

Electra says the refinery will process cobalt hydroxide sourced from the Democratic Republic of the Congo (DRC), with the material shipped through South Africa and Montreal before being refined in Canada.

Reducing reliance on China

China currently dominates global cobalt refining, processing more than 75 per cent of the world’s supply. By establishing refining capacity in Canada, the project aims to diversify supply chains and improve North America’s access to a mineral considered essential for electric vehicles, consumer electronics and defence technologies.

Electra CEO Trent Mell says critical minerals have become increasingly important not only for transportation and renewable energy, but also for national security.

The refinery has received financial support from both the Canadian and U.S. governments, reflecting growing efforts to build more resilient domestic supply chains for critical minerals.

Industry sees both opportunity and challenges

While demand for cobalt is expected to increase, some industry experts note that evolving battery technologies could reduce future dependence on the metal. Others point to ongoing concerns surrounding cobalt mined in the DRC, particularly related to human rights and responsible sourcing.

Electra says it is committed to responsible procurement practices and believes cobalt will remain a critical material, particularly as demand grows in defence applications alongside the electric vehicle market.

A new chapter for the town of Cobalt

The refinery also represents an economic transformation for the historic mining community of Cobalt. Once one of the world’s leading silver-producing regions following the area’s famous 1903 discovery, the town is now positioning itself as a key hub in North America’s battery materials industry.

Although commercially viable local cobalt reserves have yet to be developed, the new refinery could help establish Cobalt as an important processing centre, supporting Canada’s broader strategy to strengthen its critical minerals sector and secure the supply chain for next-generation technologies.
