On October 15, 2026, the Governments of Canada and Ontario announced up to $19.6 million for the City of St. Thomas through the Development Charge Reduction Program, part of the Canada-Ontario Partnership to Build. In return, St. Thomas is reducing residential development charges by 30 percent for single-detached homes and multi-unit housing, and by 50 percent for all remaining housing types, for the period March 30, 2026 to March 31, 2029. The funding backfills the DC revenue St. Thomas forgoes by cutting the charge so the city can still fund growth infrastructure. The announcement follows similar federal-provincial DC reduction deals for Toronto, Mississauga, Peel Region, Vaughan, and other Ontario municipalities throughout 2025 and 2026.
St. Thomas has become the latest Ontario city to convert a federal-provincial funding commitment into a hard cut to development charges. On October 15, 2026, Canada and Ontario committed up to $19.6 million through the Development Charge Reduction Program so St. Thomas can lower its residential development charges without creating a hole in its capital budget.

The two-tier reduction structure matters for product selection. A builder focused on single-detached or stacked townhomes captures a 30 percent reduction. A builder developing purpose-built rental, affordable housing, or other unit types that fall outside those two categories captures a 50 percent reduction on the city development charge. Confirm the exact rate that applies to your unit type with the City of St. Thomas before modeling.

Check my site →St. Thomas, the county seat of Elgin County, has been one of the fastest-growing mid-sized cities in southwestern Ontario. The Amazon fulfilment centre and the Volkswagen EV battery plant at the nearby St. Thomas site have accelerated population projections significantly, creating demand for workforce and market housing at a scale the city was not previously planning for.
That growth context makes the DC reduction timing material: a city that needs to build fast and is facing a wave of demand from industrial employment gains benefits from anything that improves the economics of residential construction. For builders who had been watching the St. Thomas market, the 30 to 50 percent reduction to March 2029 changes the feasibility of projects that were marginal at full charge rates.
The Development Charge Reduction Program applies to City of St. Thomas development charges. Elgin County development charges and education development charges are separate and are not the subject of this announcement. Pull the full charge stack before relying on any cost figure.
St. Thomas joins a growing list of Ontario municipalities that have entered DC reduction agreements under the Canada-Ontario Partnership to Build: Toronto (40 to 60 percent), Mississauga (50 percent, rental to zero), Peel Region (50 percent to November 2026), Vaughan (to zero for qualifying projects to October 2027), and Essex County (all types, to December 2030). The pattern is consistent: federal-provincial funding backfills the DC reserve, and the municipality agrees to hold a reduction for a defined window. For builders, the question is always the same: can the permit issue inside the window?
St. Thomas is reducing development charges by 30 percent for single-detached homes and multi-unit housing, and by 50 percent for all remaining housing types, for the period March 30, 2026 to March 31, 2029, as part of an up-to-$19.6 million federal-provincial funding commitment announced October 15, 2026.
The up-to-$19.6 million comes from the Governments of Canada and Ontario through the Development Charge Reduction Program, part of the Canada-Ontario Partnership to Build. It backfills the development charge revenue St. Thomas forgoes by cutting the charge so the city can still fund growth infrastructure such as water, wastewater, and roads.
No. The reduction applies to City of St. Thomas development charges only. Elgin County development charges and education development charges are separate and are not the subject of this announcement.
The reduction window runs from March 30, 2026 to March 31, 2029. Development charges are typically payable at building permit, so the practical deadline is getting a building permit within that window.
St. Thomas has benefited from major industrial investment, including an Amazon fulfilment centre and the Volkswagen EV battery plant nearby, which have accelerated population and housing demand projections significantly above prior municipal planning targets.
