Development charges are set by municipal by-law, they vary sharply between municipalities, and they are one of the few line items on a project budget that can legally move after a purchase agreement is signed. Pricing one in early means understanding both what it funds and when it actually falls due.
Key takeaways
Development charges exist to fund the infrastructure new development draws on — “fees collected from developers to help pay for the cost of infrastructure required to provide municipal services to new development, such as roads, transit, water and sewer infrastructure, community centres and emergency services facilities,” per Toronto’s own description. Timing depends on the category: Toronto’s rental and institutional charges are “payable at occupancy and in instalments,” while non-rental residential charges are “payable at occupancy” as a single amount. That single fact — the charge crystallizes at occupancy, not at the building-permit application — is what makes early estimating a moving target rather than a one-time lookup.
Toronto’s own site is explicit that its page “is intended only as a guide” and that interested parties should “review the applicable development charges bylaw and legislation or consult with the Toronto Building Division to determine charges that may apply for specific land development proposals” — which is itself useful information for an estimate: the published rate schedule is a starting point for pricing, not the final number until the bylaw and any applicable exemption are checked against the specific project.
Development charges are “legally imposed on the builder,” but “the builder typically passes them on to the buyer through the purchase agreement,” and “many new home purchase agreements in Ontario include a clause allowing the builder to pass on any increase in development charges that occurs between the date of signing and the date of closing,” per who pays, in practice. “If development charges rise between signing and closing, you may have very limited ability to challenge the increase” — and because charges are “separate from the purchase price and from land transfer tax,” they don’t show up inside the headline price at all.
Charges “vary significantly between municipalities and can add tens of thousands of dollars to the effective cost of a new home,” which is the practical reason for pricing a range early rather than a single figure: the estimate needs to cover the municipality’s current rate and a reasonable allowance for the pass-through clause to move before closing, not just today’s published number.
In 2025, two distinct authorities changed how Toronto’s development charges behave, and confusing which one did what leads to pricing off a stale assumption. On the city side, Toronto Council “removed indexing for 2025 and 2026,” cancelled “the below grade conditional permit policy,” and added “exemptions for developments with up to six units,” per Toronto’s own page. Separately, the provincial government amended the development-charges framework through Bill 17, implemented in two phases — June 5, 2025 and November 3, 2025. Removing the annual indexing adjustment is a Toronto Council decision; the Bill 17 phase-in is a provincial legislative change. A rate that looked correct before either change may reflect neither of them now, which is a reason to re-check the published bylaw rather than reuse a figure from an earlier project.
A deferral agreement is a separate mechanism from the pass-through clause. It “lets a developer or owner delay paying charges normally due at building permit stage, often in exchange for security or an agreement registered against the property,” per how a deferral works. Whether an unpaid deferred amount follows the property to a new owner “depends on how the specific agreement was structured” — “where the obligation is tied to the land itself, rather than being a purely personal promise from the original owner, a new owner can end up responsible for outstanding deferred amounts after closing.”
For anyone estimating on a property that has already gone through a development-charge deferral, that means the estimate isn’t complete until someone has done a lawyer’s title search “for deferral agreements and confirm[ed] outstanding amounts before closing” — an unpaid, land-tied deferral is exactly the kind of number an early estimate can otherwise miss entirely, because it doesn’t show up as a current municipal rate at all.
A worked example
A developer signs a purchase agreement for a six-storey rental building in a mid-size Ontario municipality in January 2026, with the published development charge for that building class at $38,000 per unit for 60 units — a budgeted $2,280,000 line item at signing. The municipality’s DC bylaw carries its own annual indexing clause (a mechanism distinct from Toronto’s 2025–26 freeze, which applies only inside Toronto), and between signing and the projected occupancy date 18 months later, two indexing adjustments apply, moving the rate to roughly $40,400 per unit — a change the purchase agreement’s pass-through clause allows the builder to carry forward, for a revised total near $2,424,000, a $144,000 increase the original budget line didn’t capture.
Because the charge is payable at occupancy rather than at signing, the estimate that matters for financing purposes isn’t the day-one figure — it’s the day-one figure plus a reasonable allowance for the number of indexing cycles between signing and the realistic occupancy date. Pricing only the current rate, without pricing the pass-through clause’s room to move, is the estimating gap that shows up as a financing shortfall closer to occupancy rather than as a line-item error today.
The builder, as a matter of law — but purchase agreements commonly let the builder pass any increase between signing and closing on to the buyer, per how the pass-through clause works, so the practical answer depends on the agreement’s wording.
It depends on the charge category. In Toronto, rental and institutional charges are payable at occupancy and in instalments, while non-rental residential charges are payable at occupancy as a lump sum, per the city’s own page. That timing, not the building-permit application date, is what an early estimate should be pricing toward.
Toronto Council removed the annual indexing adjustment for 2025 and 2026, which is different from freezing the underlying rate schedule itself. The province separately phased in its own Bill 17 amendments on June 5 and November 3, 2025 — two distinct changes worth checking separately against the current bylaw.
It depends on how the deferral agreement is structured. Where the obligation is tied to the land rather than being a personal promise from the original owner, an unpaid deferred amount can become the new owner’s responsibility — which is why a title search for deferral agreements before closing matters, per how a deferral binds successors.
