Which Korean Battery Companies Have Factories in Quebec?
On this page
Two Korean battery-materials companies — POSCO Future M and EcoPro — chose Bécancour, a small industrial town on the St. Lawrence River in Quebec, Canada, for their North American cathode plants. Neither is in full production yet: POSCO Future M’s joint venture is scheduled to start phase 1 in late October 2026, and EcoPro’s plant has slipped to 2027 after two construction halts, so the “battery cluster” that most North American coverage, fixed on Georgia and Michigan, still overlooks is being built rather than already humming.
Quick answers
- EcoPro and POSCO Future M are the two Korean battery companies with cathode plants in Bécancour, Quebec: Ultium CAM (POSCO Future M and GM) starts phase 1 in late October 2026, while EcoPro CAM Canada has been pushed to 2027.
- They make cathode and precursor materials — the energy-hungry middle of the battery chain — not finished cells, which Korean firms still assemble in Georgia and other US states.
- Quebec won them with the cheapest low-carbon hydropower in North America plus Canada’s USMCA status, which lets the materials qualify for US EV tax credits that shipments straight from Korea cannot.
Which Korean Battery Companies Have Factories in Quebec, Canada?
EcoPro and POSCO Future M are the two, and both sit in the same place: the industrial park in Bécancour, between Montreal and Quebec City. POSCO Future M holds 85 percent of Ultium CAM, a cathode active material joint venture with General Motors that is scheduled to begin phase 1 operations in late October 2026 with 20,000 tons of annual capacity — three years behind its original September 2023 target, after the EV slowdown put the launch on hold (Korea Herald, 20 Oct 2025). EcoPro’s plant, EcoPro CAM Canada, is a 1.2 trillion won project first planned with SK On and Ford; construction stopped twice in 2024, Ford later pulled out, and mass production was pushed to 2027 (Businesskorea, 19 Aug 2024; Korea Herald on Ford’s exit). Read the trade press closely and you’ll notice neither delay made much noise outside battery circles — part of why the cluster stays under-covered for anyone outside the industry. Since the early 2020s this one town has been lining up one of the densest concentrations of EV battery material plants in North America, even if the machines are only now starting to turn.
Why Did Korean Battery Companies Choose Quebec?
The pull is electricity, priced and measured. Making cathode and precursor material is power-hungry work, and Hydro-Québec sells some of the cheapest electricity on the continent, generated almost entirely by hydroelectric dams rather than fossil fuels. That matters twice over. The cost per kilowatt-hour is low, and the carbon attached to each unit is low — and automakers, the end customers, increasingly have to report the carbon footprint of their battery supply chain. A clean grid stops being a slogan and becomes a line item.
Why Build in Canada Instead of Shipping From Korea?
Because of how the US Inflation Reduction Act’s clean-vehicle tax credit is written. To qualify, a set share of a battery’s critical minerals must be extracted or processed in the US or in a country with a US free trade agreement. Canada qualifies through USMCA; Korea has no equivalent minerals arrangement. Material refined in Bécancour can flow into a US-assembled pack without disqualifying the vehicle from the credit — material shipped straight from Korea generally cannot. Quebec has marketed this gap deliberately, pitching its battery cluster, the “filière batterie,” to Asian materials producers as of 2026.
How Close Are These Quebec Plants to US Automakers?
Close enough to truck parts across in a day. Bécancour sits within a day’s drive of GM, Ford, and Stellantis assembly and cell plants in Ontario, Michigan, and Ohio. Shorter cross-border logistics cut both freight cost and the lead time automakers plan around, which counts for more as EV schedules tighten. None of this required the Korean firms to move final assembly — only the mid-chain steps that gain the most from cheap, clean power and FTA-qualifying geography.
Frequently Asked Questions
Q: What does POSCO Future M’s Ultium CAM plant in Quebec make?
Ultium CAM is a joint venture between POSCO Future M (85 percent) and General Motors that will produce cathode active material — a key battery ingredient — at the Bécancour industrial park; phase 1 is scheduled to start in late October 2026 at 20,000 tons a year, feeding GM’s Ultium Cells plants (Korea Herald).
Q: Are Korean firms the only battery companies in Quebec’s Bécancour cluster?
No. Bécancour’s “filière batterie” also includes joint ventures and plants backed by German, American, and Canadian firms; the Korean materials makers are a major but not exclusive part of it.
Q: Do the Quebec plants replace Korean battery factories in Georgia or Michigan?
No. The Quebec sites handle mid-chain materials processing, while the larger, better-known Korean battery plants in Georgia and other US states continue to assemble finished cells.
Q: Where is Bécancour, and why does the battery industry care about it?
Bécancour is a small town on the St. Lawrence River between Montreal and Quebec City; its mix of cheap hydropower, port access, and USMCA-linked tax eligibility has made it a magnet for EV battery material plants since the early 2020s.
Trace a Korean-made EV battery back far enough and a real share of it begins not in Georgia, but in a Quebec town most drivers have never heard of.
