One of Canada’s biggest bets on the electric-vehicle economy will take longer to pay off than originally planned. Volkswagen subsidiary PowerCo Canada has pushed the expected start of operations at its $7-billion battery-cell factory in St. Thomas, Ontario, to 2029, two years later than the timeline announced when the project was unveiled in 2023.
The company says construction is continuing, but the schedule is being adjusted to reflect changing market demand, advances in battery technology and Volkswagen Group’s longer-term strategy. The move comes during an unusually complicated period for EV manufacturers. Canadian electric-vehicle registrations are recovering after a difficult 2025, battery prices are falling, competition is intensifying and automakers are reconsidering how quickly they need new manufacturing capacity. For St. Thomas, the result is not a cancelled megaproject, but a longer and potentially more uncertain road to full production.
A 2027 Opening Has Become a 2029 Start
When Volkswagen and PowerCo formally detailed the St. Thomas project in April 2023, production was projected to begin in 2027. PowerCo now says operations are expected to start in 2029, describing the revised schedule as part of an effort to align construction and product planning with evolving demand and technological changes. The later date is intended to give the factory room to incorporate newer battery technology while allowing production capacity to expand according to market conditions.
Importantly, work has not stopped. PowerCo announced the new timetable while naming Mississauga-based EllisDon as general contractor for the next stage of construction. That phase will include major structural work, utilities and core factory infrastructure. Concrete work was already underway in 2025. PowerCo has characterized the shift as getting the pace of the investment right rather than retreating from Canada, although the change means southwestern Ontario will wait considerably longer for the plant to reach its most important milestone: producing battery cells.
The Original Plan Was Enormous Even by Auto-Industry Standards
The scale of St. Thomas helps explain why a two-year shift matters. Volkswagen committed up to $7 billion to what PowerCo described as its first North American cell factory and its largest planned gigafactory. The original design called for as much as 90 gigawatt-hours of annual capacity at full expansion, theoretically enough battery cells for roughly one million electric vehicles a year.
Employment expectations were similarly large. The project was announced with plans for as many as 3,000 direct jobs once operational, along with thousands of jobs throughout construction, suppliers and the broader regional economy. PowerCo’s roughly 350-acre manufacturing site is part of a much larger industrial development assembled around St. Thomas. The factory was intended to become an anchor for an emerging battery corridor linking Ontario’s automakers with materials processors and component suppliers. Those ambitions have not officially disappeared, but the latest PowerCo announcement did not provide a revised date for reaching full capacity or specify how large production will be when operations begin in 2029.
PowerCo Is Building for a Market That Keeps Changing
PowerCo’s explanation for the revised timetable is deliberately broad. It points to market demand, technological advancement and Volkswagen Group strategy rather than one single problem. That distinction matters because the EV market has been moving in different directions simultaneously. Electric-vehicle adoption continues to increase globally, but growth rates vary sharply between countries, while automakers are adjusting model plans, prices and production investments more frequently than they did several years ago.
A battery factory planned in 2023 therefore has to compete in a very different environment by the time equipment is installed later this decade. Building too much capacity too early can leave enormously expensive machinery underused. Building too little creates the opposite problem when demand accelerates. PowerCo says the St. Thomas facility will retain the ability to scale as conditions develop. The approach gives Volkswagen additional flexibility, but it also means the final size and speed of the Canadian factory’s ramp-up may increasingly depend on EV sales several years from now rather than the assumptions that shaped the original announcement.
Canada’s EV Market Fell Hard — Then Started Recovering
Canadian data helps explain why forecasting battery demand has become difficult. New zero-emission vehicle registrations dropped 34.7 per cent in 2025 and represented 9.5 per cent of new registrations, down from 14.6 per cent in 2024. Part of that decline came after buyers rushed into the market before incentives changed, making late-2024 comparisons unusually strong.
The picture improved in 2026. Statistics Canada recorded 58,811 new zero-emission vehicle registrations during the second quarter, up 26.7 per cent from the same period of 2025. ZEVs accounted for 10.7 per cent of new registrations, and Ontario registrations rose 46.6 per cent year over year. Ottawa has also introduced a new EV Affordability Program offering qualifying buyers up to $5,000 toward eligible battery-electric vehicles in 2026. Those numbers hardly suggest Canadians have abandoned electric cars. Instead, they show a market that remains highly sensitive to pricing, incentives and economic conditions — precisely the kind of volatility that complicates billion-dollar factory planning.
Battery Economics Have Changed Dramatically Since the Deal Was Signed
Volkswagen is also entering a battery industry where costs have been falling faster than many manufacturers expected. BloombergNEF calculated that average lithium-ion battery-pack prices dropped another eight per cent in 2025 to a record US$108 per kilowatt-hour. Manufacturing overcapacity, aggressive competition and increased adoption of lower-cost lithium-iron-phosphate chemistry were among the forces pushing prices downward.
At the same time, the International Energy Agency estimates global lithium-ion battery manufacturing capacity exceeded four terawatt-hours by the end of 2025, roughly 30 per cent higher than a year earlier. More than 80 per cent of that capacity was located in China. Global EV battery deployment still increased strongly, reaching about 1.2 terawatt-hours in 2025, but producers outside China face an increasingly difficult challenge: manufacturing advanced cells at prices competitive with enormous Asian supply chains. For St. Thomas, waiting longer could allow newer manufacturing methods and chemistries to be incorporated before large-scale production begins rather than locking the factory into technology selected years earlier.
Volkswagen Itself Is Under Much More Financial Pressure
The timetable adjustment also comes while Volkswagen Group is dealing with significant financial strain. On September 18, the company sharply reduced its 2026 outlook, saying it expected an operating return on sales of no more than one per cent. Volkswagen said roughly €10 billion in special effects, including restructuring expenses and impairment charges connected with Porsche, were expected to weigh on its results.
Its EV performance has also become increasingly regional. Volkswagen Group delivered about 438,500 fully electric vehicles worldwide during the first half of 2026, down 5.8 per cent from a year earlier. European BEV deliveries increased 8.4 per cent, but U.S. deliveries fell 68.8 per cent and Chinese deliveries dropped 47.9 per cent. That uneven picture is important for a Canadian plant designed primarily around the North American market. Volkswagen is still investing heavily in electrification, but the company has stronger incentives than it did three years ago to control spending, match factory capacity more closely to demand and avoid adding expensive production before vehicles need it.
A Later Opening Could Mean a More Advanced Factory
Battery technology itself is advancing quickly enough that two years can materially change what comes off a production line. PowerCo has built its strategy around what it calls the Unified Cell, a standardized format that can accommodate different chemistries while reducing manufacturing complexity. Volkswagen says the architecture can support technologies ranging from conventional nickel-manganese-cobalt cells to lower-cost LFP chemistry and, eventually, solid-state batteries.
PowerCo began producing its first Unified Cells at its Salzgitter factory in Germany in December 2025. Volkswagen has said the format could eventually be used in more than 80 per cent of the group’s battery-electric vehicles. PowerCo is also working with QuantumScape on solid-state technology, with a commercial solution targeted for around the end of the decade. None of that confirms that St. Thomas will produce solid-state cells in 2029. PowerCo has not identified the specific “next-generation” technology behind the delay. Still, the flexible architecture helps explain why waiting can carry technological value as well as financial cost.
Billions in Public Support Make the New Timeline Especially Important
The St. Thomas investment came with one of the largest government support packages ever associated with a Canadian manufacturing project. Ottawa committed $700 million toward upfront capital costs, while Ontario pledged $500 million in direct incentives and additional spending on infrastructure. The federal government also offered production support designed to match incentives available under the U.S. Inflation Reduction Act.
That production support was originally estimated at between $8 billion and $13.2 billion depending on output. Crucially, the federal commitment was structured around cells actually produced and sold rather than simply construction of the factory. The original framework also called for support to begin phasing down in 2030 and disappear after 2032. A 2029 start therefore places initial production much closer to that scheduled phase-down than the original 2027 opening would have. Neither PowerCo’s latest announcement nor the publicly available government statements accompanying it provide a new subsidy schedule. That leaves an important unanswered question about how the revised factory timeline interacts with the financial assumptions behind the original agreement.
St. Thomas Has Already Started Building Around the Factory
For St. Thomas, the gigafactory has never been just another industrial building. Local planning has been reshaped around expectations of thousands of jobs, new suppliers and substantial population growth. The city is updating its official plan through 2051, while its transit planning documents say the population could approach 80,000 by that year. Hundreds of hectares of industrial land have also been assembled to accommodate PowerCo and businesses expected to form around it.
That means a delay can ripple well beyond Volkswagen’s construction site. Housing developers, infrastructure planners, retailers and suppliers have all been preparing for a larger workforce. St. Thomas Mayor Joe Preston has nevertheless pointed to ongoing construction and PowerCo’s existing local workforce as reasons for confidence, estimating that roughly 500 people already work for the company in the area. The central question is therefore shifting from whether the factory exists to how quickly it grows. The buildings are going up. What remains uncertain is how large the operation will be when the production lines finally start running in 2029.
The revised schedule underscores how much has changed since Volkswagen first chose Ontario. Electric vehicles remain a major part of the global auto industry, but the path toward mass adoption has become less predictable. Canadian demand weakened and then rebounded, battery prices dropped, Chinese manufacturing expanded rapidly and Volkswagen entered a far more aggressive restructuring period.
PowerCo is still building in St. Thomas, and selecting a general contractor for major structural work is a tangible sign that the investment remains active. Yet 2029 changes the equation for governments, suppliers, workers and the city itself. The next three years will determine whether the extra time produces a more competitive, technologically advanced factory or simply postpones the economic payoff Ontario expected to begin receiving much sooner.
