Buying a pre-construction property in the Greater Toronto Area (GTA) is an exciting milestone. With interest rates stabilizing in 2026, locking in a brand-new build with an extended deposit structure is once again a highly attractive strategy for both first-time buyers and seasoned investors. However, many buyers make a critical mistake: they calculate their down payment perfectly but completely forget that pre-construction closing costs are vastly different from resale properties.
On a standard resale home, your closing costs are relatively predictable (mostly Land Transfer Tax and legal fees). With a new build, structural hookups, municipal growth fees, and builder adjustments can add thousands to your final bill. If you aren’t prepared, you could face a major financial squeeze on final closing day.
Whether you are looking at a sleek high-rise condo, a freehold townhome, or a spacious detached single-family home, here is the transparent, localized breakdown of the hidden fees you must look out for before signing an Agreement of Purchase and Sale.
What Are Pre-Construction Closing Costs vs. Resale Fees?
When you buy a resale property, what you see is generally what you get. On closing day, you pay the balance of the purchase price, your land transfer taxes, and your lawyer.
With pre-construction, you are buying a promise from a developer. Between the day you sign the contract and the day you get the keys, the municipality charges the developer various fees to accommodate the new building. The developer then passes those costs down to you via “builder adjustments.”
Altogether, typical pre-construction closing costs in Ontario can range anywhere from 4% to 8% of the purchase price.
The Hidden Builder Adjustments: Development Levies
Development levies and education charges are fees imposed by local municipalities (like the City of Toronto or York Region) to fund the public infrastructure needed for a growing population—think parks, roads, transit expansions, and schools.
These levies are the single biggest variable in your closing costs. If the municipality raises its infrastructure fees while your building is under construction, the developer can pass that entire increase onto you at final closing.
The Golden Rule: Never sign a contract without a capped levy clause. During your 10-day cooling-off period, your real estate lawyer should negotiate with the builder to put a strict financial ceiling on these development charges.
For example, an uncapped levy on a large detached home or townhome in a high-growth zone could balloon unexpectedly to $30,000. If your lawyer successfully negotiates a cap of $12,000, the developer must absorb any cost above that amount. This simple step protects your budget from sudden inflation.
The Condo-Specific Phase: Understanding Interim Occupancy Fees
If you are buying a pre-construction condominium, you have a unique phase to plan for called Interim Occupancy. Freehold detached homes and townhomes bypass this phase completely—you simply close the transaction and take full ownership on possession day.
For condos, interim occupancy is the period when the builder deems your unit safe to move into, but the municipality hasn’t yet legally registered the condo corporation.
During interim occupancy:
- You get the keys and can move in (or rent the unit out, if your contract allows an “owner right to lease”).
- You do not own the unit yet, and your mortgage has not started.
- You must pay the developer a monthly Interim Occupancy Fee.
Think of this fee as “phantom rent.” None of this money goes toward your mortgage principal or your down payment. By law, this monthly fee is strictly calculated based on the interest on the remaining balance of the purchase price, estimated municipal property taxes, and projected monthly condo maintenance fees.
Navigating the Double Land Transfer Tax Squeeze
Your geographical choices across the GTA have a massive impact on your tax bill, regardless of your property type.
If you buy a pre-construction property directly within the city limits of Toronto, you are subject to the Double Land Transfer Tax squeeze. You must pay both the Ontario Provincial Land Transfer Tax and the Toronto Municipal Land Transfer Tax.
However, if you shift your focus to northern GTA sectors like Richmond Hill, Markham, or Vaughan, you only pay the provincial portion.
| Purchase Price | Estimated Land Transfer Tax (Inside Toronto) | Estimated Land Transfer Tax (Markham / Richmond Hill) | Total Tax Savings |
| $750,000 | ~$23,000 | ~$11,475 | $11,525 |
| $1,000,000 | ~$33,000 | ~$16,475 | $16,525 |
| $1,250,000 | ~$43,000 | ~$21,475 | $21,525 |
Note: First-time homebuyers may qualify for provincial and municipal tax rebates to offset these amounts.
The Low-Rise Variance: Finishes, Tarion, and Grading
If your heart is set on a freehold townhouse or a detached single-family home rather than a condo, your hidden fees shift from “occupancy fees” to structural and warranty adjustments.
When buying low-rise pre-construction, be mindful of these unique closing adjustments:
- Tarion Warranty Enrolment: All new-build homes in Ontario must be registered with Tarion. The enrolment fee is tied to the purchase price, meaning larger detached homes command higher upfront warranty fees at closing.
- Lot Grading and Tree Planting: Builders frequently pass down the municipal fees for grading the land, sodding the lawn, and planting boulevard trees directly into your closing adjustments.
- Design Studio Upgrades: While a condo usually includes a standard set finish package, detached home builders offer extensive customization (hardwood upgrades, kitchen cabinetry expansions, oak stairs). If you don’t pay for these upgrades during the design phase, they are added to your final adjustment statement on closing day.
The Investor Trap: HST Rebates and Rental Rules
If you are purchasing a pre-construction property as an investment rather than a primary residence, you need to understand how the Canada Revenue Agency (CRA) handles HST.
The sticker price advertised by GTA developers almost always assumes the buyer qualifies for the HST New Housing Rebate, meaning the buyer intends to move into the property as their primary residence.
If you plan to rent the home or condo out to a tenant instead:
- You must pay the HST rebate amount (up to $24,000) upfront to the developer on final closing day.
- Once you secure a solid one-year lease agreement with a tenant, you can apply directly to the CRA to get that $24,000 back via the HST New Residential Rental Property Rebate.
While you do eventually recover the money, you must have that extra $24,000 in liquid cash available on closing day to bridge the gap.
Practical Steps to Protect Your Investment
To ensure a smooth, surprise-free closing on your new build, follow this procedural checklist from day one:
1. Utilize the Cooling-Off Period: Day 1 to 10.
Use your initial signing window (statutory 10 days for condos, or negotiated conditional windows for freeholds) to hand your contract to an experienced real estate lawyer to review the fine print.
2. Negotiate Caps on Builder Adjustments During the Review.
Have your lawyer explicitly request caps on development levies, education charges, and utility connection fees (water, electricity, gas meters) to eliminate financial surprises down the road.
3. Confirm Assignment Sale Rules: Before Finalizing.
If your financial situation changes over the 3-5-year construction timeline, you may need to sell the contract via an assignment sale. Ensure your contract explicitly grants permission for assignment sales and check what fees the builder charges to process it.
4. Monitor Mortgage Stress Test Rules: Ongoing.
Keep in regular close contact with your mortgage broker. Even if you are pre-approved today, changes to Canadian lending stress tests or personal credit shifts can impact your final mortgage approval when the building completes.
