One of Canada’s biggest bets on the electric-vehicle economy will take longer to pay off than originally expected. Volkswagen battery subsidiary PowerCo has pushed the start of operations at its C$7-billion battery-cell factory in St. Thomas, Ontario, to 2029, two years later than the 2027 target announced when the project was unveiled.
The factory has not been cancelled, and construction is continuing. PowerCo says the revised schedule will give it room to incorporate next-generation battery technology and adjust the plant’s eventual scale to market demand. Even so, a two-year shift matters for a project tied to thousands of expected jobs, extensive public support and major infrastructure spending across southwestern Ontario. It also arrives while automakers are reassessing how quickly the North American EV market will grow.
The 2027 Opening Date Has Become 2029
Volkswagen and PowerCo arrived in St. Thomas in 2023 with an ambitious timeline. The company said groundbreaking would follow and battery-cell production was projected to begin in 2027. Ontario was still publicly describing the facility as being on track for initial 2027 production when concrete work was celebrated at the site in October 2025. Less than a year later, that timetable changed. PowerCo now says the facility is expected to begin operations in 2029.
That makes the new date two years later than Volkswagen’s original public target. PowerCo disclosed the shift in September while announcing EllisDon as general contractor for the next stage of construction. The company tied the new schedule to changing market demand, technological developments and Volkswagen Group’s longer-term product strategy. For St. Thomas residents who have watched earthworks, foundations and structural steel steadily transform farmland into an industrial complex, the important distinction is that construction continues even though the date when batteries start leaving the factory has moved substantially further into the future.
PowerCo Says It Is Slowing the Pace, Not Backing Away
PowerCo has been careful about how it characterizes the change. Executives say the company is trying to get the “pacing” of the investment right rather than stepping back from Canada. The new development model is deliberately phased, allowing PowerCo to keep erecting buildings and installing infrastructure while leaving itself more flexibility over how quickly production equipment and capacity are added. The company still describes St. Thomas as a cornerstone of its North American battery strategy.
That wording matters because a phased build can look very different from the original vision of a factory racing toward full production. PowerCo says it will align the timing, scale and configuration of the facility with future demand. Its September update did not provide a new date for reaching the plant’s originally advertised maximum capacity. Nor did it replace the original 3,000-job target with a revised manufacturing employment number. The commitment therefore remains substantial, but some of the most important details—how large the first production phase will be and how quickly later phases follow—remain dependent on conditions closer to 2029.
EllisDon Is Taking the Project Into Its Next Construction Phase
The change in production timing is happening alongside a significant construction milestone. PowerCo selected Canadian construction company EllisDon as general contractor as the St. Thomas project moves into core structural and infrastructure work. That stage includes the production-building shell, mechanical and electrical systems, plumbing, energy infrastructure, utilities and other services needed before battery-making equipment can operate inside the complex.
About 60 EllisDon employees were on site when the latest construction phase was announced, with that workforce expected to grow to roughly 1,300 at peak. Other contractors and personnel will also be working on parallel activities. Groundbreaking took place in 2025, and companies including Magil Construction Canada and Steelcon have already worked on foundations and structural components. The scene is therefore different from an industrial project placed on indefinite hold: workers and heavy equipment remain active. For local skilled trades, the delay in battery production does not mean construction employment disappears immediately. Instead, the build continues while PowerCo retains more control over when manufacturing capacity is commissioned.
The Factory’s Enormous Scale Makes a Two-Year Delay Significant
The St. Thomas project was never pitched as an ordinary factory. Volkswagen said the site could ultimately reach annual battery-cell capacity of up to 90 gigawatt-hours in its final expansion phase. At the time of the original announcement, the company and governments said that would be sufficient for as many as one million electric vehicles annually, depending on battery size and configuration. Volkswagen described it as PowerCo’s largest planned gigafactory.
The manufacturing site itself occupies roughly 370 acres, while the surrounding Yarmouth Yards industrial and supplier park covers about 1,500 acres. Volkswagen initially projected as many as 3,000 highly skilled jobs inside the battery plant, alongside thousands of indirect positions. Those numbers help explain why moving production from 2027 to 2029 resonates well beyond Volkswagen. Suppliers, tradespeople, municipal planners and businesses across the London–St. Thomas region have been preparing around the expectation of a giant new industrial employer. Even if the same long-term facility eventually emerges, the economic activity associated with full-scale battery production will arrive later than originally promised.
Billions in Public Support Put the Timeline Under Greater Scrutiny
The factory is also unusual because of the scale of government support attached to it. Ottawa committed a C$700-million non-repayable contribution toward construction of the St. Thomas facility. Ontario separately committed C$500 million in direct incentives while promising hundreds of millions more for supporting infrastructure. Those commitments helped Canada compete with the generous manufacturing incentives created in the United States by the Inflation Reduction Act.
The larger figure often associated with the Volkswagen deal—up to C$13 billion—is performance-based rather than simply an upfront cheque. Canada and Ontario agreed that Volkswagen could qualify for those incentives based on batteries actually produced and sold, with the federal government responsible for two-thirds of the performance support and Ontario one-third. The arrangement was structured in response to competing U.S. incentives and can change if corresponding American support changes. That design is important when assessing the 2029 timeline. The biggest portion of public assistance is linked to actual production, but taxpayers and communities can still reasonably watch closely because governments have already committed capital, infrastructure and resources to making the project possible.
St. Thomas Has Already Started Building Around the Gigafactory
For St. Thomas, Volkswagen’s arrival triggered planning far outside the plant fence. The city’s Yarmouth Yards industrial park covers 1,500 acres and includes a roughly 377-acre PowerCo property as well as land designated for other major manufacturers. The city estimates development across the broader industrial park could generate about 5,000 direct and indirect jobs and as many as 4,000 construction jobs over the next decade. Those figures encompass Yarmouth Yards as a whole, not just Volkswagen.
Infrastructure is being expanded alongside that industrial growth. St. Thomas lists new or improved hydro capacity, highways, local roads, sewers and water systems among the investments serving the district. A new Dalewood Water Reclamation Facility is also under construction, with completion expected in the second quarter of 2029. Ontario previously committed infrastructure funding for roads, rail, electricity, water, police and fire services around the Volkswagen development. That helps explain why a factory schedule change is felt throughout the community. Municipal preparations were designed around an economic transformation, not merely the construction of one private building.
Canadian EV Demand Is Recovering, but the Market Has Been Unpredictable
PowerCo’s reference to “evolving market demand” comes during an unusually volatile period for electric vehicles. Canadian zero-emission vehicle registrations have recently improved. Statistics Canada counted 58,811 new ZEV registrations in the second quarter of 2026, up 26.7 per cent from the same quarter in 2025. They represented 10.7 per cent of all new vehicle registrations, while Ontario recorded a particularly strong 46.6 per cent year-over-year increase.
Those figures do not mean manufacturers have enjoyed a smooth demand curve. The second-quarter national total was still well below the 81,216 ZEVs registered in the fourth quarter of 2024. Statistics Canada also reported slower ZEV growth during 2025, when changes to purchase incentives affected the market. The picture in 2026 is therefore one of recovery rather than uninterrupted expansion. A battery factory designed to operate for decades must be sized around long-term vehicle production, not one strong quarter. PowerCo’s decision suggests Volkswagen wants more flexibility before committing the St. Thomas facility to its originally envisioned production ramp.
Battery Technology Is Changing While the Ontario Factory Is Being Built
Technology is the other major reason PowerCo gives for the later launch. Volkswagen has spent the past several years developing what it calls the Unified Cell, a standardized battery architecture that can be adapted to multiple chemistries. Its first PowerCo factory in Salzgitter, Germany, began producing Unified Cells in late 2025. Volkswagen says the initial NMC version offers roughly 10 per cent more energy density than earlier cells and works with the group’s new cell-to-pack battery design.
Salzgitter is particularly relevant to Ontario because Volkswagen calls it the lead plant for PowerCo’s subsequent factories in Valencia, Spain, and St. Thomas. Processes and experience developed there are intended to be transferred to Canada. Volkswagen says the Unified Cell architecture can accommodate chemistries ranging from lithium iron phosphate and nickel-manganese-cobalt to future solid-state technologies. PowerCo has not publicly specified which exact next-generation chemistry will launch in St. Thomas in 2029. The additional time could nevertheless allow the Canadian plant to start with more mature manufacturing processes and newer technology than it would have used under the original 2027 schedule.
Volkswagen Is Not the Only Automaker Reworking Ontario EV Plans
The PowerCo delay is part of a wider recalibration in Ontario’s EV manufacturing sector, although the circumstances of each project are different. Honda originally planned a C$15-billion electric-vehicle value chain in Ontario, including EV and battery manufacturing. After first postponing that plan, Honda Canada announced in May 2026 that the project was being suspended indefinitely, citing evolving business conditions, a revised resource strategy and shifting customer demand.
General Motors has made its own adjustment. In October 2025, GM ended production of the BrightDrop electric delivery van at its CAMI Assembly plant in Ingersoll after saying the commercial electric-van market had developed much more slowly than anticipated. Production had already been suspended months earlier. These examples do not mean Ontario’s battery strategy is collapsing; other investments continue to operate or move ahead. They do show how dramatically assumptions formed during the EV investment boom of 2022 through 2024 have changed. Automakers are now balancing electrification plans against consumer demand, technology costs, trade policy and the risk of building capacity faster than vehicles can absorb it.
The Biggest Question Is What the Plant Looks Like When 2029 Arrives
The most important development now is not simply whether a building opens in 2029, but how much battery production PowerCo installs when operations begin. The company’s latest language repeatedly emphasizes the ability to scale over time. That creates the possibility that the St. Thomas factory could begin with a smaller production footprint and expand as Volkswagen’s North American EV volumes justify additional capacity. PowerCo has not announced a revised timetable for reaching the original maximum of 90 GWh.
For workers and suppliers, the difference is meaningful. Construction activity is proceeding and is expected to intensify, but the thousands of permanent manufacturing positions associated with full battery production arrive later. For governments, the project remains central to the strategy of anchoring battery manufacturing in Canada rather than importing cells from overseas. And for Volkswagen, the extra two years offer a chance to install more mature technology while avoiding premature capacity. The C$7-billion project remains alive and highly consequential. What has changed is the certainty surrounding how quickly its original promise becomes reality.
