Community Benefits Charges: What Toronto Charges Developers for Every Extra Floor of Density
Three separate charges hit a condo pro forma, under three separate statutes, with three separate formulas. The CBC is the one most often mis-modelled — because people apply the 4% to the wrong number, and because the rules changed three times since 2019.
What is a Community Benefits Charge, and how is it different from a development charge?
A Community Benefits Charge (CBC) is a municipal levy authorized by section 37 of Ontario’s Planning Act, used to fund the capital cost of public services needed because of new growth. According to Ontario.ca, it is capped at 4% of the value of the land, valued as of the day before the first building permit is issued, and it can only be imposed on developments of five or more storeys that add ten or more residential units — both tests must be met. Critically, a CBC does not replace development charges or parkland dedication. It stacks on top of them, under a different statute, with a different formula.

I’m Arthur Zhao. Here is a quick test of whether a condo pro forma was built by someone who reads statutes or someone who copied last year’s spreadsheet: ask what the 4% is multiplied by. If the answer is anything other than the appraised value of the dirt on a specific date, the model is wrong — and usually wrong by seven figures. The Community Benefits Charge is a young, heavily amended instrument that replaced a negotiation-based regime most people in this industry spent a decade learning. This is what it actually says today, and where the traps sit.

The 4% is a ceiling on a number most people get wrong
Second, and more expensive: the multiplicand is land. Not gross development value. Not total revenue. Not hard construction cost. The appraised value of the land itself. I have seen 4% applied to a project’s sell-out value in a back-of-envelope model — that error inflates the line by an order of magnitude and can kill a viable deal on paper.
You are charged on value your own approval created
By the time that date arrives, the land is fully entitled. It carries approved height, approved density, approved use. It is worth dramatically more than the day you bought it — and the reason it is worth more is the entitlement you spent years and money securing. The CBC is assessed against that uplifted value.
The cash-flow consequence compounds it: the charge is payable before the permit issues, which is before a shovel moves and long before a single unit closes. It lands on the most expensive capital in the project.
The trigger is an AND gate, and it has sharp edges
• A 4-storey, 60-unit stacked townhouse block → no CBC (fails the storey test, despite the unit count)
• A 5-storey boutique building adding 9 units → no CBC (fails the unit test, despite the height)
• A 5-storey building adding 10 units → CBC applies
Notice how thin that last margin is. The difference between the second and third example is one unit — and it switches on a charge worth up to 4% of the entire land value. That is a genuine cliff edge, not a gradient, and it is worth knowing exactly which side of it a marginal unit puts you on before the site plan is finalized.
⚠️If your project sits within a unit or a storey of the trigger, model it both ways before you finalize the design. Adding a tenth unit to a five-storey building does not add 4% of that unit’s value — it can add up to 4% of the entire site’s land value. That is a cliff, and it deserves a deliberate decision rather than an accidental one.
Three charges, three statutes — they stack
• Development Charges — Development Charges Act, 1997. Fixed amounts by unit type. Funds specific services: water, wastewater, roads, transit.
• Parkland dedication — Planning Act s.42. Land conveyance or cash-in-lieu.
• Community Benefits Charge — Planning Act s.37. A percentage of land value, funding capital costs of public services not already recovered through the other two.
That last clause is the only relationship between them. The anti-double-dipping rule means a CBC cannot re-collect what a DC or parkland provision already collected. It does not mean you pick one. You pay all three.
💡 The old regime was a negotiation; the new one is arithmetic. Under pre-2022 Section 37 density bonusing, the price of extra height was whatever you and the City talked each other into — it varied by project, by ward, by councillor, and it was close to unforecastable at land acquisition. The CBC replaced discretion with a capped formula. Whether that is good or bad depends on which side of the table you sat on: developers traded flexibility for certainty, and communities traded bespoke benefits for a predictable percentage.
What Bill 23 actually changed — and what still has not started
Bill 23 (More Homes Built Faster Act, 2022) received Royal Assent on November 28, 2022. It amended the s.37(32) calculation with a formula that factors out the floor area of existing buildings and structures, so the ceiling reflects only the value attributable to the new development rather than the whole property. That change came into force on Royal Assent — it is live.
A second formula, which factors out the floor area of affordable and attainable residential units, was drafted to come into force on a day to be proclaimed by the Lieutenant Governor. Awaiting proclamation is not the same as in force. Separately, Ontario.ca notes that affordable-housing exemptions and discounts took effect June 1, 2024. If your model depends on any of these, verify the current status before you rely on it.
Who is exempt
Toronto layers additional local exemptions on top, including Housing Now developments and applications under 10,000 square metres of residential gross floor area that were submitted and deemed complete before August 15, 2022. Municipal exemptions vary — a class that is exempt in Toronto is not automatically exempt in Mississauga or Ottawa, because each municipality writes its own by-law within the provincial ceiling.
Dispute the number, but pay it first
The practical takeaway: your appraisal work should be done before the permit is pulled, not after the invoice arrives. Once you are inside the 30-day window you are working against a clock, on the City’s timetable, with your money already gone.
ℹ️Section 37 has been rewritten three times since 2019 — Bill 108, Bill 197, then Bill 23 — and at least one CBC formula is still waiting on proclamation. Treat every article about this topic, including this one, as a snapshot with a shelf life. Before you commit capital, have a planning consultant or municipal lawyer confirm the currently in-force provisions against your municipality’s latest by-law.
Frequently Asked Questions
Do I pay a community benefits charge on a four-storey building?
No. Planning Act s.37(4) bars a CBC on buildings of fewer than five storeys, and separately on developments adding fewer than ten residential units. Both tests must be met before the charge can apply, so a four-storey project is outside the regime regardless of how many units it contains. This is why the CBC is effectively a mid-rise and high-rise instrument and rarely comes up in low-rise development.
Is the 4% based on land value or on what the finished building is worth?
Land value only. According to Ontario.ca, the charge cannot exceed 4% of the value of the land as of the day before the first building permit is issued. It is not calculated on the completed building, on sell-out revenue, or on construction cost. But note the timing works against you: by that date the land is fully entitled, so it appraises well above what you paid for it.
Does a CBC replace development charges?
No — they stack. Development charges are levied under the Development Charges Act, 1997 for specific services like water, wastewater and transit. The CBC is levied under Planning Act s.37 as a percentage of land value, and funds capital costs not already recovered through development charges or parkland dedication. That anti-double-dipping rule is the only link between them. A qualifying condo project pays all three.
Can I refuse to pay while I dispute the land valuation?
No. The permit will not issue until the charge is paid. If you believe the amount exceeds what the legislation allows, you pay under protest and then have 30 days to submit your own appraisal; the municipality has 45 days to respond with its own. Within 5% of each other, you get refunded down to the higher appraisal; more than 5% apart, a third appraiser decides. Get your appraisal ready before permit stage.
Why did Ontario replace Section 37 density bonusing?
Bill 108 (More Homes, More Choice Act, 2019) replaced the negotiated density bonusing regime with the CBC, and the old regime stopped applying to new development as of September 18, 2022. The stated rationale was cost certainty: under the old system the price of extra height was negotiated project by project and was difficult to forecast when buying land. The trade-off is that a capped percentage is more predictable but far less flexible than a bespoke community benefit package.
