Buying a new build can be amazing—brand-new everything, modern layouts, and often less maintenance at the start. But it’s also very different from buying resale, because you’re signing a contract first and getting the finished home later. That gap is where most people have the most questions and concerns.
Below is a practical, Ontario-focused guide to help you understand the process, the protections for both buyer and builder, and the incentives that may apply—especially if you’re a first-time buyer.
1) What counts as a “new build”?
In Ontario, “new build” usually means one of these:
- Pre-construction: You buy from plans (condo or freehold) before the home is finished.
- Inventory / quick-close: The builder already built (or is nearly finished) and you buy closer to completion.
- Custom build: You own/close on land first and then build (or hire a builder to build).
A key Ontario point: New homes built by a licensed builder/vendor are typically covered by Ontario’s mandatory new home warranty system, administered by Tarion Warranty Corporation, with builder licensing regulated by Home Construction Regulatory Authority.
2) The biggest difference vs resale: the Agreement of Purchase and Sale (APS)
With resale, you negotiate and usually include conditions (financing, inspection, etc.). With new builds, the builder’s APS is often non-negotiable and heavily drafted to manage construction risk.
That’s why the single best move is:
Have a real estate lawyer review the APS before your firm date
Ontario’s builder regulator specifically recommends legal review because terms can be complex and affect deposits, timelines, changes, and cancellations. HCRA
Typical APS sections that matter a lot:
- Deposits: schedule, where held, and what happens if the deal collapses
- Closing/occupancy dates and how extensions work
- Adjustments on closing (development charges, levies, utility hookups, etc.)
- Upgrades (what you’re actually paying for, deadlines, and refund rules)
- “Material changes” (what the builder is allowed to change without your approval)
- Assignment clause (whether you can sell the contract—more below)
- Warranty & deficiency process (how you report issues after move-in)
3) Buyer protections you should know (and what they actually cover)
A) Verify the builder is licensed
Before you sign, you can search the Ontario Builder Directory (run by the HCRA) to confirm licensing and see background info.
B) Deposit protection (this one matters)
Ontario provides deposit coverage for many new home purchases, but limits depend on the home type and price.
Why it matters: If a project fails or the builder becomes insolvent, deposit protection can be the difference between “we’re devastated” and “we’re covered (at least up to the limit).”
C) Warranty coverage after you move in (1-, 2-, and 7-year style protections)
Ontario’s new home warranty framework includes coverage periods (for example, issues tied to workmanship/materials and building code in the early period, and major structural defects over the longer period).
mportant reality check: Warranties don’t mean “every tiny cosmetic detail gets fixed instantly.” There are processes, timelines, and standards.
D) Delayed closing / delayed occupancy compensation rules
Ontario has specific protections around closing date delays (freehold) and occupancy date delays (condos), including required disclosure and potential compensation (up to a cap in some cases).
E) Condo-specific: the 10-day cooling-off period
In Ontario, new condo buyers generally have a 10-day cooling-off period after receiving the required documents, during which they can rescind for any reason and get their deposit back.
Freehold cooling-off? There has been discussion/proposals about extending similar protections to freehold in Ontario, but implementation details depend on regulations and timing.

4) Builder protections (why the contract looks the way it does)
Builders carry real risks: supply chain delays, labour shortages, permit delays, weather, changing code requirements, lender draw schedules, and more.
To manage that, builder APS documents typically include:
- Broad rights to extend dates (sometimes with “unavoidable delay” language)
- Permission to substitute materials/finishes (especially if discontinued/back-ordered)
- Caps and allowances for adjustments (development charges, utility fees, etc.)
- Strict default rules if the buyer can’t close (interest, termination rights, and damages)
This isn’t “evil builder stuff”—it’s the business reality of constructing at scale. Your job as a buyer is to understand what you’re accepting and budget for it.
5) The real-world pros and cons of buying a new build
Pros
- Brand-new systems (roof, HVAC, plumbing, electrical start at “zero”)
- Modern layouts and efficiency (open concepts, better insulation, newer windows)
- Customization (structural options + finishes/upgrades, depending on build stage)
- Potentially lower repairs early on
- Warranty framework can provide structured recourse for certain defects and delays
Cons / risks
- You may wait months/years and dates can shift
- Closing costs can be higher than you expect (adjustments, levies, utility hookups)
- Appraisal risk: if market values dip, your lender may appraise lower than your price
- You can be “house-poor” on move-in if upgrades + closing costs weren’t budgeted
- Neighbourhood is unfinished (construction noise, dust, incomplete amenities)
- Condo interim occupancy can mean paying occupancy fees before final closing (common with condos; talk to your lawyer)
6) Legal and practical “watch-outs” that deserve extra attention
A) Development charges, levies, and “adjustments”
Many buyers are shocked at closing because of extra line items. Your lawyer can explain:
- What is capped vs uncapped
- What is an estimate vs guaranteed amount
- What’s common in that builder’s documents
B) HST and rebates on new homes
New builds often involve HST rules and rebates. Key concepts:
- GST/HST New Housing Rebate exists federally and provincially (eligibility depends on factors like intended use—primary residence vs rental—and other criteria).
- First-time home buyers’ GST/HST rebate (proposed, federal): The CRA has published details describing a proposed rebate aimed at first-time buyers purchasing a new home from a builder (with specific eligibility and timing conditions)
Because rebate eligibility can be technical, treat this as “get advice early”—especially if:
- You might rent it out instead of living in it
- A family member will live in it
- You’re buying through a corporation
- You’re buying on assignment
C) Assignment sales (selling your contract before closing)
Assignments can be allowed or restricted by the builder, and they have tax implications. CRA guidance notes that assignment sales of newly constructed/substantially renovated housing are taxable for GST/HST purposes (rules have evolved in recent years).
Translation: don’t assume “I’ll just assign it if I need to” is simple.
D) “Right to terminate” and cancellation risk
Some pre-construction projects get cancelled. Understand:
- When the builder can cancel
- What you get back (deposit + interest rules)
- What happens to upgrades and extras
7) Incentives and benefits that may apply (especially for first-time buyers)
Here are the most common Canada/Ontario incentives buyers ask about:
A) RRSP Home Buyers’ Plan (HBP)
Allows eligible buyers to withdraw from RRSPs to buy or build a qualifying home, up to the program limit.
B) First-Time Home Buyers’ Tax Credit (HBTC)
A federal non-refundable tax credit for eligible first-time buyers (often described as up to a $10,000 claim, which can reduce taxes payable).
C) Ontario land transfer tax refund for first-time buyers
Ontario offers a refund for eligible first-time buyers (rules and maximums applyD) Toronto municipal land transfer tax rebate (if buying in Toronto)
D) Toronto municipal land transfer tax rebate (if buying in Toronto)
Toronto has its own municipal rebate opportunities for eligible first-time buyers.
E) First-Time Home Buyer Incentive (CMHC) is closed
The Canada Mortgage and Housing Corporation states the First-Time Home Buyer Incentive is no longer accepting applications.
Pro tip: Incentives are often about eligibility + timing + paperwork. Plan them before you sign, not a week before closing.

8) A smart “new build” checklist (use this before you sign)
- Confirm the builder is licensed (Ontario Builder Directory).
- Have your lawyer review the APS (especially dates, caps, adjustments, termination, assignment).
- Clarify deposits: how much, when, how held, and deposit protection limits.
- Budget a closing-cost cushion (new builds are notorious for “extras”).
- Understand timing: tentative vs firm dates; condo interim occupancy; delay compensation rules.
- Plan financing early (rate holds, approval windows, appraisal risk).
- Confirm HST/rebate assumptions in the contract—especially if your plan could change.
- Document upgrades: what’s included, deadlines, and refundability.
- If condo: know your 10-day rescission window and use it to do legal/financial due diligence.
9) When a new build is a great idea (and when it might not be)
A new build can be a strong fit if you:
- Want something modern and low-maintenance early on
- Have flexibility on timing
- Have the budget buffer for closing adjustments and upgrades
- Prefer a structured warranty framework
You may want to be more cautious if you:
- Need a firm move-in date (job relocation, school deadline, selling your current home)
- Are stretching to qualify (less room for appraisal surprises)
- Don’t have savings beyond the deposit
- Expect “custom home” control on a production builder timeline
Quick disclaimer:
This post is educational and Ontario-focused, but it isn’t legal or tax advice. New build contracts are technical—your real estate lawyer and tax professional should review your exact situation.
