Cash-to-close guide

New Build Closing Costs Ontario Calculator

New-build buyers often know the purchase price and deposit schedule, but not the full cash needed for final closing.

The exact amount depends heavily on the agreement and statement of adjustments.

What does this page answer?

Plan Ontario new-build closing costs including land transfer tax, CMHC PST, legal fees, Tarion allowance, adjustments, development charges, and HST rebate timing.

Editable assumptions cover legal/title/disbursements, Tarion, adjustments, occupancy fees, and development charges.
Toronto and non-Toronto land transfer tax are separated.
The closing ledger is designed as a buyer/lawyer/builder checklist.

Search intent: Buyer wants a complete new-build closing-cost estimate rather than a single rebate, tax, or insurance calculation.

Why do generic calculators miss the closing problem?

A land transfer tax calculator, rebate calculator, or CMHC calculator only explains one line. New-build buyers need the combined cash-flow view because the lawyer's trust ledger reflects multiple programs and builder-specific adjustments.

Which documents improve accuracy?

The best inputs usually come from the agreement of purchase and sale, deposit schedule, mortgage approval, Tarion/HCRA addendum, development charge cap, and builder statement of adjustments.

Quick questions

Why do new-build closing costs vary so much?

Builder contracts can pass through adjustments, development charges, utility fees, and occupancy costs that differ by project and municipality.

Should development charges be zero?

Usually not by default. The calculator lets buyers edit this amount and flags a zero value as a confidence risk for new homes.
