GM and POSCO pause the second phase of their Bécancour cathode-material plant (Ultium CAM)

Quebec Economy Minister Christine Fréchette confirmed on 16 October 2025 that phase 2 (more output plus a precursor plant) was paused indefinitely; GM Canada cited evolving market dynamics. Phase 1, part of a plant planned for 30,000 t/yr and first due in 2024, is still expected to start production in 2026. As a result, Vale cancelled its planned nickel sulphate plant in Bécancour. Electrive also notes that BASF's Bécancour cathode project is on hold and that EcoPro BM's plant was suspended, with Ford withdrawing from it.

How it bears on the outcome

Explanation	Fit	Why
O0 No meaningful speed-up	Fits moderate	Investment decisions that pause or cancel several Bécancour battery-material projects are consistent with a build-out that is not speeding up in this sector.
O1 Faster, but the extra output goes mostly elsewhere	Against weak	A paused expansion and a cancelled nickel sulphate plant would be somewhat surprising if the build-out were speeding up; the cited cause is market conditions, not destination of output.
O2 Faster, and more volume reaches the US (this level or higher)	Against weak	A paused expansion and a cancelled nickel sulphate plant would be somewhat surprising if the build-out were speeding up; the cited cause is market conditions, not destination of output.
O3 Locked-in preferential terms for the US	Against weak	The output was meant for a US automaker's supply chain, yet the expansion is paused and no locked-in US terms appear; not what this reading expects.
