Pre-Construction Closing Costs in Ontario: A Complete Breakdown

Closing costs on pre-construction homes in Ontario can add $30,000 to $60,000 or more beyond the purchase price. Here is a detailed breakdown of what to expect.

Why Pre-Construction Closing Costs Are Different

Closing costs for a pre-construction home in Ontario are typically higher and more complex than those for a resale purchase. In addition to the standard costs that apply to all real estate transactions (land transfer tax, legal fees, title insurance), pre-construction buyers face a range of builder-related charges and municipal levies that can add significantly to the total cost of purchase.

Understanding these costs in advance is essential for accurate budgeting. Buyers who focus only on the purchase price may be caught off guard at closing when these additional charges come due.

Standard Closing Costs

Ontario Land Transfer Tax

The Ontario land transfer tax applies to all property purchases in the province. It is calculated on a graduated scale:

  • 0.5% on the first $55,000
  • 1.0% on $55,001 to $250,000
  • 1.5% on $250,001 to $400,000
  • 2.0% on $400,001 to $2,000,000
  • 2.5% on amounts above $2,000,000

For a $900,000 home, the Ontario land transfer tax would be approximately $12,950. First-time buyers may qualify for a rebate of up to $4,000, reducing this to approximately $8,950.

Properties in Vaughan are not subject to Toronto's additional municipal land transfer tax, as Vaughan is part of York Region, not the City of Toronto.

Legal Fees

A real estate lawyer handles the closing paperwork, title registration, and fund transfers. Legal fees for a pre-construction closing typically range from $1,500 to $3,000, plus disbursements (title searches, registration fees, courier charges, etc.). Pre-construction closings tend to be at the higher end of this range due to the additional complexity of the transaction.

Title Insurance

Title insurance protects against title defects, survey issues, and certain other risks. The cost is typically $300 to $500 for a residential property and is a one-time premium paid at closing.

Pre-Construction-Specific Costs

Development Charges

Development charges are fees levied by the municipality to fund infrastructure improvements associated with new development, including roads, water and sewer systems, parks, and community facilities. In York Region and Vaughan, development charges can be substantial, sometimes reaching $50,000 or more depending on the home type and the rates in effect at the time of building permit issuance.

Whether you pay these charges directly depends on your Agreement of Purchase and Sale. Some builders include development charges in the purchase price or cap their exposure. Others pass the charges through to the buyer at whatever rate applies, which can increase if the municipality raises the rates between the time you sign and the time the builder pulls the permit.

Education Levies

The provincial government imposes education development charges on new residential construction. These are separate from the municipal development charges and are typically several thousand dollars.

Utility Connection Fees

New homes require connections to municipal water, sewer, hydro, and natural gas services. These connection fees are often passed through to the buyer and can range from $3,000 to $8,000 depending on the municipality and the services being connected.

Meter Installation Fees

Water meters and in some cases hydro meters need to be installed in the new home. Installation fees are typically a few hundred dollars per meter.

Park Dedication and Cash-in-Lieu Fees

Municipalities often require developers to dedicate parkland or pay a cash-in-lieu fee for park development. This cost may be included in the purchase price or passed through as a closing adjustment.

Grading and Landscaping Deposits

Builders often collect a refundable deposit (typically $3,000 to $5,000) to ensure that final grading and landscaping meet municipal standards. This deposit is returned once the work is completed and inspected, but it represents a cash outlay at closing.

Enrolment Fee

The Tarion Warranty Corporation charges builders an enrolment fee for each new home. This fee is sometimes passed through to the buyer as a closing cost adjustment, typically ranging from $1,000 to $2,000.

HST Considerations

The Harmonized Sales Tax (HST) applies to new home purchases in Ontario at a rate of 13 percent. For most freehold pre-construction homes, the builder includes the net HST in the purchase price, assuming the buyer qualifies for the GST/HST New Housing Rebate by living in the home as their primary residence.

If you do not qualify for the rebate (for example, if you plan to rent the property or use it as an investment), the full HST may be payable at closing. On a $900,000 home, this can mean an additional obligation of $80,000 or more. This is one of the most significant potential costs in pre-construction, and it must be clarified in the APS before signing.

Sample Closing Cost Estimate

For a $900,000 pre-construction freehold home in Vaughan, a reasonable estimate of closing costs might look like this:

  • Ontario Land Transfer Tax: $12,950 (less $4,000 rebate if first-time buyer)
  • Legal Fees and Disbursements: $2,500
  • Title Insurance: $400
  • Development Charge Adjustment: $5,000 to $25,000 (varies by agreement)
  • Education Levy: $3,000 to $5,000
  • Utility Connection Fees: $4,000 to $7,000
  • Meter Fees: $500
  • Grading Deposit (refundable): $4,000
  • Tarion Enrolment Fee: $1,500

Estimated Total: $34,000 to $60,000+ (in addition to the purchase price)

How to Prepare

The most important step you can take is to have your Agreement of Purchase and Sale reviewed by a lawyer who can identify every potential closing cost and help you understand which charges are capped and which are variable. Build a financial cushion above the minimum expected closing costs to account for adjustments that may increase before closing.

Your mortgage broker should also be aware of these costs, as the funds needed at closing include both your remaining down payment and all closing cost obligations. Planning for these expenses early in the process will help you avoid surprises on closing day.
