St. Thomas, Ontario is the construction site of PowerCo SE's $7-billion, 350-acre battery gigafactory, which is now expected to begin operations in 2029, two years later than first planned, and to create about 3,000 direct jobs. The city's 2026 municipal tax rate increases 6.1%, driven by an 8.9% municipal levy increase partially offset by approximately 2.8% assessment growth from new construction. A median residential property assessed at $205,000 pays roughly $16 more per month — about $196 per year — raising the municipal portion of the bill to approximately $3,412 annually. Housing supply is responding in two directions. Central Elgin is developing 3,500 new homes across 370 acres of the former St. Thomas Psychiatric Hospital lands. Vicano Developments acquired 67.75 acres on Ron McNeil Line for industrial supplier warehousing. Development charges of approximately $12,323 per single or semi-detached unit, plus $8,815 in designated growth areas, are payable upon building permit issuance to offset the infrastructure deficit caused by this rapid industrialization.

548 490 4577What is the PowerCo SE gigafactory in St. Thomas, Ontario?
PowerCo SE is Volkswagen Group's battery cell subsidiary. Its St. Thomas facility broke ground in October 2025 on a 350-acre municipal site. In September 2026 the company moved the start of operations from 2027 to 2029, to build in next-generation battery technology. Construction is continuing, with EllisDon as general contractor.
| Metric | Value |
|---|---|
| Operator | PowerCo SE (Volkswagen Group subsidiary) |
| Capital investment | Approximately $7 billion |
| Site area | 350 acres |
| Groundbreaking | October 2025 |
| Start of operations | Now expected 2029 (originally 2027) |
| Direct jobs at full operation | 3,000 |
| Planned output | Battery cells for approximately 1 million EVs annually |
A second employer is already operating in the same labour catchment: Amazon's 2-million-square-foot robotics fulfillment centre in Talbotville, between London and St. Thomas, opened in October 2023 with more than 1,000 full-time positions. Employment growth in the corridor therefore precedes PowerCo's start of operations, now expected in 2029, rather than following it.
How much are St. Thomas property taxes increasing in 2026?
St. Thomas council accepted a 2026 draft budget in principle in December 2025. The figures below reflect that draft. Council had not issued final approval as of publication.
| Component | 2026 figure |
|---|---|
| Municipal levy increase | 8.9% |
| Assessment growth offset | approximately 2.8% |
| Net municipal tax rate increase | 6.1% |
| Median residential assessment | $205,000 |
| Annual increase on median assessment | approximately $196 |
| Monthly increase on median assessment | approximately $16 |
| Resulting municipal portion, annual | approximately $3,412 |
The increase applies to the municipal levy independent of any change in a property's assessed value. It funds roads, water, wastewater, and emergency services capacity scaled to the industrial and residential growth described below.
How does the St. Thomas property tax rate compare to nearby Ontario cities?
| Municipality | 2025 residential tax rate | Position |
|---|---|---|
| Woodstock | approximately 1.82% | Highest of the four |
| St. Thomas | approximately 1.72% | Second |
| London | approximately 1.68% | Third |
| Kitchener | Among the lowest of large Ontario cities | Lowest of the four |
St. Thomas sits in the upper range for Ontario municipalities of comparable size. The 2026 increase widens the gap between St. Thomas and London.
What new housing is being built to absorb gigafactory employment?
Two projects account for the largest committed land area in the corridor. They serve different functions and sit in different municipalities.
| Attribute | Central Elgin residential | Vicano Developments industrial |
|---|---|---|
| Land area | 370 acres | 67.75 acres |
| Location | Former St. Thomas Psychiatric Hospital lands, Central Elgin | Ron McNeil Line |
| Use | Residential | Industrial supplier warehousing |
| Scale | 3,500 new homes | Warehousing capacity for gigafactory supply chain |
| Function in corridor | Mitigates housing demand generated by the 3,000 direct jobs | Houses tier-one and tier-two suppliers serving PowerCo |
| Timeline posture | Phased buildout | Immediate |
| Governing municipality | Central Elgin | St. Thomas |
The Central Elgin project is the primary supply-side response to gigafactory labour demand. The Vicano acquisition is a demand-side driver: supplier warehousing adds a second layer of employment beyond PowerCo's 3,000 direct positions, and that employment also requires housing.
What are development charges in St. Thomas and when are they payable?
Development charges (DCs) are one-time municipal fees levied per new unit to fund the infrastructure required by growth. They are payable upon building permit issuance. Their function is to offset the infrastructure deficit caused by rapid industrialization — the gap between existing servicing capacity and the roads, water, and wastewater capacity that new industrial and residential construction requires.
| Charge type | Amount per single or semi-detached unit |
|---|---|
| Municipal-wide and urban-service charges combined | approximately $12,323 |
| Northwest Area 1 area-specific charge (additional) | approximately $8,815 |
| Total in Northwest Area 1 | approximately $21,138 |
These figures are indexed annually each January against Statistics Canada construction price data. The current schedule should be confirmed with the City of St. Thomas or the builder before it is used in a purchase calculation.
Do development charges increase the advertised price of a new home?
The charge is levied on the builder, not the purchaser, and is generally embedded in the advertised price rather than added at closing. Two variables affect this:
- Indexation. Charges adjust each January, so a price quoted before an indexation date may not reflect the charge the builder ultimately pays.
- By-law renewal. DC by-laws and area-specific charges are periodically revisited as growth areas build out, independent of annual indexation.
Purchasers signing a new-construction agreement should confirm in writing whether the quoted price accounts for the current schedule.
What data should be monitored for the remainder of 2026?
| Variable | Status | What changes it |
|---|---|---|
| 2026 municipal tax rate | Draft, accepted in principle December 2025 | Final council budget approval |
| Development charge schedule | Current, indexed January | Annual indexation; DC by-law renewal |
| PowerCo start of operations | Moved to 2029 in September 2026 | Construction schedule; market demand |
| Central Elgin 3,500-unit buildout | Approved, phased | Servicing capacity, permit issuance |
| Ron McNeil Line supplier warehousing | Acquired, immediate development | Supplier tenancy announcements |
Where do these figures come from and what are their limits?
The tax figures reflect a draft budget accepted in principle, not a final approved rate. Development charge figures reflect a published schedule subject to annual January indexation. Employment figures reflect operator projections at full operation, not current headcount. Tax rate comparisons use 2025 residential rates. Each figure should be verified against the current municipal source before it is used in a financing or purchase decision.
