What's actually in a pre-construction contract? Not one document, but a stack: the main APS + Schedule A (legal description) + Schedule B (builder's unilateral addendum, the most critical part) + Schedules C/D (upgrades and credits) + the TARION Addendum (statutory protection that cannot be waived).
Key fact 1: A new freehold APS is governed by the New Home Construction Licensing Act, 2017 (HCRA-regulated) and the Tarion Act; a new condo unit APS is governed by the Condominium Act, 1998, Section 73. Both grant a 10-day cooling-off (rescission) period during which the buyer can rescind unconditionally and get the deposit back in full.
Key fact 2: The TARION Addendum (Statement of Critical Dates) sets out unilateral-extension rules, material change notice, deposit insurance, and delayed closing compensation — and these cannot be overridden by Schedule B. Any Schedule B clause contrary to or inconsistent with the Addendum is void to that extent.

What is the 10-day rescission period in a pre-construction contract and how to use it?
The 10-Day Rescission — Your Real Due Diligence Window
Signing isn't the finish line — it's the start. After signing, you have 10 calendar days (not business days) to rescind unconditionally. The core task in those 10 days is to have a real estate lawyer review the contract — not to go home and celebrate. Lawyers run through 5–9 high-priority clauses. 90% of buyers never use this window, and silently inherit every hidden builder right.
When Does the Clock Start?
Freehold new home: 10 calendar days from the date the buyer signs (New Home Construction Licensing Act).
Condo unit: 10 calendar days from the date the buyer receives a copy of the signed APS and the Disclosure Statement together (Condominium Act s.73). Watch out: it's the date of receipt of the complete package — not the signing date, not the date the sales centre handed you the deal sheet.
Real-world trap: builders often deliver in two waves — APS the night of, Disclosure Statement by email days later. For condos, the 10 days run from receipt of the later document. Have your lawyer confirm the receipt date and preserve the email timestamp as evidence.
9 Clauses Your Lawyer Must Review
A pre-construction contract review usually runs $400–$800 (separate from final closing), with a written report in 1–2 business days. The report should walk through these 9 clauses one by one:
- Occupancy / Closing dates (Firm vs Tentative, Outside Closing Date)
- Definition of Material Change
- Builder unilateral modification rights + square footage tolerance
- Adjustments / Levies / Cap (the easiest place to lose $20k–$40k)
- HST New Housing Rebate (kept by builder or assigned to buyer)
- Assignment clause (fee, consent, profit clause)
- Deposit Trust / Insurance (where the money sits, who insures it)
- Upgrade / Colour selection deadlines + cancellation rules
- Right of First Refusal / Restrictive Covenants
Part 2 below walks each of these clauses in detail.
How to Rescind — Format, Channel, Timing
Rescission needs no reason, but must be written (lawyer letter or email + signed PDF), delivered before the 10-day deadline to the builder or its solicitor. Use both email and courier with delivery confirmation.
Refund: the builder must return the deposit in full within a reasonable time (typically 10–20 business days), no deductions for fees, upgrades selected, or sales commission. Refusal or partial refund is unlawful — file a complaint with HCRA / Tarion.
What are the 9 critical clauses inside Schedule B of a pre-con contract?
Schedule B — 9 Clauses, One by One
Schedule B is the builder's own addendum — it unilaterally rewrites clauses that looked balanced in the main APS. Ordered below by dollar impact: ① highest cost (uncapped adjustments can cost $40k+), ② next (HST rebate misalignment $24k), ③ timing risk, ④ flexibility.
Occupancy / Closing — Firm vs Tentative
The TARION Addendum distinguishes Firm dates (fixed; if the builder delays more than 7 days, the buyer can rescind and recover the deposit in full) from Tentative dates (provisional; the builder may extend per Addendum rules up to the Outside Occupancy / Closing Date — often 4–5 years after signing). Schedule B defaults to Tentative.
Read this: the Outside Occupancy Date and Outside Closing Date are the builder's absolute latest delivery dates. If Schedule B contains "extend by an additional period" beyond the Addendum's permitted extensions, have your lawyer flag it — that's the builder bolting on extra extension rights on top of the standard regime.
2026 reality: average GTA pre-con delivery is 14–22 months later than Tentative Occupancy (Urbanation 2024 GTA pre-con report), and 20%+ of projects hitting the Outside Date trigger Tarion Delayed Closing Compensation ($150/day, capped at $7,500).
Material Change — Only "Material" Lets You Walk
Condominium Act s.74 requires the builder to notify the buyer in writing of any material change to the Disclosure Statement, giving the buyer 10 days to rescind. But — the definition of "material" lives in Schedule B. Typical builder language: "material change does not include unit number change, floor adjustment, ±2% floor area variation, exterior material substitution, common element redesign…"
Negotiation point: ask your lawyer to extract the items you care about most from the "non-material" list — e.g., relocation from floor 12 to floor 5, balcony removed, exposure changed. These are typically deemed non-material by default. You can ask (within the 10-day window) for "unit number changes require buyer consent" to be added. Builders often refuse but sometimes concede on unit relocation.
Builder Modification Rights + ±2% Floor-Area Tolerance
Industry standard: builder reserves "the right to make necessary modifications to exterior, common elements, and unit layouts," with "±2% floor-area variation not constituting breach or price adjustment." Your 700 sf unit could deliver at 686 sf — at $1,500/sf that's $21,000 of missing area with no price refund.
How to check: find the specific tolerance percentage in Schedule B (±2% is industry-average; some builders write ±5%, meaning a $52k loss is still not breach). Then check whether "without adjustment to purchase price" appears — if yes, the builder can shrink your unit without refund.
For small units (under 500 sf) the math hurts more: smaller base = bigger percentage of usable layout lost.
Adjustments / Development Levies / Cap — The Financial Bomb
At closing, the builder passes on Development Charges + Education Levies + Park Levy + utility hook-ups + various admin fees. This is the Statement of Adjustments. By default Schedule B sets no cap on these — whatever the builder is charged, you pay.
Real case: a GTA condo project signed in 2018 estimated levies at $8,000; at 2022 closing the builder charged $42,000 (municipal DCs rose 220%). Because Schedule B said "levies as set by municipality at closing" with no cap, the buyer paid $34,000 over estimate to get the keys.
What your lawyer must request — add a cap:
- Development Charges + Education Levies combined cap $10,000–$15,000 (1-bed condo) / $15,000–$25,000 (2-3 bed / freehold)
- Utility hook-ups (hydro/gas/water) combined cap $2,500–$4,000
- Builder admin / legal fee cap $1,500
- Tarion Enrolment Fee — statutory, can't be capped (≈ $385–$2,066 sliding with price)
In a buyer's market (2024–2026), builders routinely accept caps; in a hot market they don't. This is one of the most valuable bargaining chips in the current pre-con market.
HST New Housing Rebate — The $24,000 Question
The HST New Housing Rebate caps out around $24,000 (federal $6,300 + Ontario $24,000 max, with Ontario rebate fully phased for prices over $450k; total cap ≈ $24,000 per CRA formula). Schedule B typically reads: "builder has incorporated the HST rebate into the advertised price, assuming the buyer qualifies for owner-occupied rebate." The implication:
- The builder takes the rebate up front via an "assignment of rebate to vendor" clause. The advertised price you see is already net of the $24k owner-occupied rebate.
- If at closing you're not owner-occupying (any form of investment, rental, vacancy, friend occupancy), CRA requires the buyer to pay $24,000 back to the builder (the builder claimed the rebate based on owner-occupied status; CRA's post-audit reverses it).
- Investor buyers can recover via the HST New Residential Rental Property Rebate (NRRPR) — same amount, but requires a signed 1-year lease and full HST upfront before reclaim. Takes 4–8 months. So at closing, expect to advance $24k cash and wait 4–8 months for CRA refund.
To verify: confirm Schedule B's "assignment of rebate" clause clearly states "if buyer does not owner-occupy at closing, buyer pays $24,000 to vendor." If the language is vague ("buyer agrees to indemnify vendor for any rebate clawback"), have your lawyer tighten it — to block the builder from adding interest or admin fees later.
Assignment Clause — The Right to Sell, and Its Cost
Assignment = transferring the contract (not yet a property) to a third party before occupancy. Schedule B by default requires written builder consent, and the builder may refuse "for any reason" (including "wrong market timing"). Four numbers to extract from the assignment clause:
- Assignment Fee: $3,000–$15,000, industry average $5,000–$10,000 (luxury builders $12k+)
- Profit Sharing: any builder cut? Common is 0%, but some builders write "if assignment price exceeds purchase price by more than 5%, vendor entitled to 25% of excess"
- Marketing Restriction: can it be listed on MLS or public sites? Schedule B often says "no public listing, no MLS, no signs"
- Window: when can assignment start? Often "after deposit reaches 20%" or "12 months after signing" — not immediately
The 2026 GTA assignment market is frozen (active listings 4× of 2022, average DOM over 180 days, most assignments trade below original purchase price). Market analysis and net-proceeds math live on the next page: Pre-Construction Assignment Contract (coming soon).
Deposit Trust — Where the Money Sits, Who Insures It
Pre-con deposits do not belong to the builder — they are statutorily held in trust. Two layers:
- Condo unit (Condominium Act): deposit must sit in the builder's solicitor's trust account, with Tarion Deposit Protection as backstop (freehold $60,000; condo tiered $20,000–$100,000 by unit price; up to $300,000 cap on high-rise units post-2017 reforms).
- Freehold new home: deposit also goes into the lawyer's trust; anything above $60,000 must be backed by builder-provided excess deposit insurance for the buyer (look for "Tarion-eligible deposit insurance certificate" in Schedule B).
Read this: Schedule B's release of deposit clause — does the builder have the right to "draw deposits from trust into the general account upon substantial commencement of construction"? This matters enormously — once funds leave trust, recovery in insolvency drops from "100% trust-protected" to "general unsecured claim." Insist on "deposit released only at occupancy."
Upgrade / Colour Selection — Deadlines & Refunds
Schedules C/D list the upgrade catalogue — but the clauses that matter are two deadlines and one cancellation rule:
- Design Studio Appointment Deadline: usually 60–90 days post-signing. Miss it and the builder applies "standard / builder's choice" — charging upgrade fees while installing default finishes
- Cancellation Window: 7–10 days post-selection to change your mind. After that, upgrades are 100% non-refundable.
- Payment Timing: most builders require full upgrade payment on signing or rolled into occupancy closing — paying years upfront for finishes marked up 60–150%
Strategy: upgrade only structural + irreversible + one-shot items (outlet placement, cabinet layout, bathroom configuration). Defer decorative upgrades (flooring, countertops, bathroom tile) to post-possession — markup roughly halves. See Pre-Construction Buying Guide → Upgrades chapter.
Right of First Refusal + Restrictive Covenants
Right of First Refusal (ROFR): some builders (mostly luxury condo and master-planned community) reserve a right to "buy back at the same price if the buyer wishes to resell or assign." This kills the assignment market upside — you can only sell back to the builder at the original price, never capturing market gains.
Restrictive Covenants: typical limits — "no short-term rentals (Airbnb) for X years," "no exterior modifications," "no RV/commercial vehicle parking," "no above-ground pools." These run with title to future buyers and affect resale. Surface them before signing.
What statutory protections does TARION provide for Ontario pre-construction buyers?
TARION Statutory Protections — What the Builder Cannot Waive
The TARION Addendum is a government-mandated standard form attached to every new-home APS. Builders can write all they want in Schedule B — but nothing may conflict with the Addendum. This section is the buyer's real backstop.
Statement of Critical Dates
Lists 4 core dates: First Tentative Occupancy / Second Tentative / Firm Occupancy / Outside Occupancy. Each extension requires a fresh Statement; failure to issue one is a breach of the Addendum.
Delayed Closing Compensation
$150/day, capped at $7,500, triggered only when the builder fails to give 90-day notice per the Addendum's extension rules. Most builders comply with notice rules, so payouts are rare.
Material Change Notice
If the builder makes a substantive change to the Disclosure Statement (structure, use, material area reduction, common element redesign), written notice within 10 days is mandatory; the buyer then has 10 days to rescind and recover the deposit in full.
Deposit Insurance
Freehold up to $60,000; condo unit tiered $20k–$100k (high-rise raised to $300k post-reform). Pays out when the builder becomes insolvent, absconds, or the contract is judicially terminated.
Interest on Deposits
The Condominium Act requires the builder to pay interest on deposits at the Prescribed Rate (about 5% in 2026), accruing from deposit-in-trust to occupancy. Freehold has no statutory interest — check Schedule B.
Early Termination Conditions
Addendum Section 10 lists "project viability" conditions (sales rate, financing, municipal approvals). If unmet, the builder may unilaterally cancel and refund all deposits with interest. This is the lawful cancellation channel.
If any Schedule B clause is "inconsistent with the TARION Addendum" — the Addendum prevails. Your lawyer letter must name the conflict and require written builder confirmation. This is the buyer's most valuable legal protection — but only usable inside the 10-day window.
Where does your pre-con deposit actually sit, and what happens if the builder goes insolvent?
Deposit Schedule + Where Your Money Sits in Insolvency
Standard GTA pre-con deposit schedule: 20–25% total (some builders require 30–35%). Below: the typical cadence and the legal recovery hierarchy if the builder fails.
Industry-Standard Cadence (example: $800,000 unit, 25% total deposit)
| Milestone | % | Amount ($800k unit) |
|---|---|---|
| On signing | 5% | $40,000 |
| 30 days post-signing | 5% | $40,000 |
| 90 days post-signing | 5% | $40,000 |
| 180 / 365 days post-signing | 5% | $40,000 |
| Interim Occupancy | 5% | $40,000 |
| Total deposit | 25% | $200,000 |
Sources: industry average per BILD GTA 2024 builder survey + Urbanation 2024 pre-con report.
Recovery Hierarchy When the Builder Becomes Insolvent
- Deposit in trust (cleanest): the lawyer's trust account is protected by trust law and not part of the builder's bankruptcy estate. 100% recoverable.
- Trust released but Tarion / Excess Deposit Insurance applies: paid out per policy cap (freehold $60k; condo tiered up to $300k).
- Amounts above insurance cap: general unsecured claim in bankruptcy. Typical recovery: 10–40% after 12–36 months.
Bottom line: deposits under $60k (most freehold) face near-zero insolvency risk. Larger condo deposits ($200k+) carry real loss risk above the Tarion cap. This is why investors track whether their deposit exceeds the insurance ceiling.
7 Questions to Ask Your Lawyer Before Signing
Don't ask the lawyer "for advice" — ask for written answers to these 7 specific questions. The review report should give 7 Yes/No + numeric answers.
-
What's the total cap on adjustments? Can my lawyer negotiate a combined DC + Education Levy cap of $15k–$25k? -
Who owns the HST rebate — builder or buyer? If I'm not owner-occupying at closing (investing/renting), exactly how much do I repay? -
What's the Outside Occupancy Date? If the builder misses it, can I rescind and recover the deposit in full? -
How is "material change" defined? Are the 3 things I care about most (unit number, floor, exposure) inside the material-change list? -
What's the assignment fee? Does the builder share in profit? When can I start assigning? -
Whose trust holds the deposit? Under what conditions can it be released to the builder? How much of my deposit exceeds the Tarion cap? -
Are any Schedule B clauses inconsistent with the TARION Addendum? Should we send a written notice flagging the conflict?
5 Common Questions About Pre-Con Contracts
Q1. I signed a pre-con contract 3 months ago and now realize the terms are unfair — can I rescind?
After the 10-day window, you can't rescind unilaterally on "unfair terms" grounds — only on triggers (builder material change, missed Outside Date, builder insolvency, Tarion arbitration award). Assignment may be an alternative exit (subject to Schedule B's terms) — see the upcoming Assignment page.
Q2. Can my lawyer actually negotiate Schedule B terms?
Depends on market + builder + leverage. In the 2024–2026 buyer's market: levy caps, HST rebate allocation, and adding items to the material change definition usually negotiate. Builder modification rights, square footage tolerance, and assignment fee almost never move. Spend your negotiation capital on the first three.
Q3. Can I read Schedule B myself? Do I really need a lawyer?
Schedule B averages 28–55 pages of legal English. Reading "what each clause means" isn't hard for buyers. What's hard is judging "is this clause tight or loose compared to GTA peers?" A lawyer review is $400–$800 — relative to $40k cap risk or $24k rebate risk, the math is overwhelming. Skipping review = gambling.
Q4. If a pre-con project is delayed past the Outside Date, am I guaranteed a rescission?
In theory yes — the TARION Addendum treats missing the Outside Date as builder default, allowing rescission + full refund + delayed compensation. In practice: (1) builders often issue a "Material Change Notice" near the Outside Date, restarting the 10-day buyer election window — you either accept the revised terms or rescind; (2) builders occasionally apply to Tarion for an extension under "Force Majeure / unavoidable delay" — if approved, the Outside Date shifts. Both happen routinely.
Q5. I signed a freehold pre-con (no Disclosure Statement) — do I still get the 10-day rescission?
Yes. The 10-day rescission for freehold new homes is mandated by the New Home Construction Licensing Act, 2017, independent of any Disclosure Statement. The 10 days run from the buyer's signing date (not from receipt of the builder's countersignature).
