Ontario is reducing municipal development charges (DCs) for new homes in 2026 through two tracks. A federal-provincial housing agreement announced by Premier Ford and Prime Minister Carney targets roughly a 50% reduction in municipal development charges across the province, including Toronto, Mississauga, and Brampton. Separately, Bill 17 (Protect Ontario by Building Faster and Smarter Act, 2025) amends the Development Charges Act to reduce or eliminate charges for affordable and rental housing and to change the timing of when DCs are payable. Most of the changes require accompanying regulations to take effect.
Development charges are among the largest costs on a new home before it is built, often tens of thousands of dollars per unit in the GTA, so any cut moves the pro forma more than almost any approval reform. In 2026, two separate mechanisms are pushing those charges down: an intergovernmental funding deal and a legislative change. They work differently, and a developer needs to know which applies to their project.
Premier Doug Ford and Prime Minister Mark Carney announced a housing agreement that targets a significant reduction in municipal development charges for new homes, on the order of a 50% cut, across Ontario, including the high-DC municipalities of Toronto, Mississauga, and Brampton. The mechanism is intergovernmental funding: senior levels of government offset the revenue municipalities would lose, so the charge to the developer falls without the municipality simply absorbing the shortfall.
A funding-based cut depends on the money flowing and each municipality enacting the reduction in its own development charge by-law. The headline figure is a target, not an automatic line-item change on every project on day one. Confirm what your specific municipality has actually adopted before you model the reduced rate.
DC rates vary sharply by municipality and are changing fast. PreBuildIQ pulls the current development charge picture for your address in 60 seconds.

The most significant timing change is that development charges for many residential projects can be paid at occupancy rather than at building permit issuance. This does not reduce the dollar amount by itself, but deferring a large charge to the end of construction materially lowers its financing cost on a multi-year build. It is paired with Building Code amendments enabling occupancy permits for residential developments with deferred development charges.
It is worth keeping the two effects distinct. A cut lowers the amount owed; a deferral changes when it is owed. The federal-provincial deal and the Bill 17 affordable and rental provisions reduce the amount for eligible projects. The Bill 17 occupancy timing change defers the payment. A well-built pro forma models both: the reduced rate that applies to the project type, and the occupancy timing on the remaining balance.
| Lever | Effect | Source |
|---|---|---|
| Federal-provincial DC reduction | Lowers the amount (target ~50%) | Ford-Carney housing deal + municipal by-laws |
| Affordable / rental relief | Reduces or eliminates the amount for eligible housing | Bill 17 / Development Charges Act |
| Occupancy timing | Defers payment to occupancy | Bill 17 + Building Code occupancy permits |
Yes. A federal-provincial housing deal announced by Premier Ford and Prime Minister Carney targets roughly a 50% reduction in municipal development charges for new homes across Ontario, including Toronto, Mississauga, and Brampton. Separately, Bill 17 reduces or eliminates charges for affordable and rental housing. Most changes require regulations and municipal by-law adoption to take effect.
The federal-provincial deal targets a reduction on the order of 50% of municipal development charges for new homes. The actual reduction on a given project depends on what the specific municipality adopts in its development charge by-law and whether the offsetting funding flows, so confirm the current rate for your municipality.
Yes. Bill 17 amends the Development Charges Act, 1997 to reduce or eliminate charges for affordable and rental housing, improve the treatment of rental and institutional developments, and change the timing of when charges are payable, allowing many residential DCs to be paid at occupancy rather than at building permit. Many details are set by regulation.
Under Bill 17, development charges for many residential projects can be paid at occupancy rather than at building permit issuance, supported by Building Code amendments enabling occupancy permits for residential developments with deferred development charges. This defers the cost rather than reducing it, lowering its financing impact on a multi-year build.
