Buying a newly built home in Ottawa can be exciting, but understanding the purchase price, HST and available rebates is an important part of making an informed decision.
Ontario has introduced temporary HST relief for eligible new homes, and some buyers may qualify for additional first-time home buyer rebates. The amount you may receive depends on the purchase, the applicable rebate programs and your individual eligibility.
Before signing an agreement of purchase and sale, take the time to understand how the builder is handling HST and rebates. Here are 10 questions worth asking.
1. Is HST included in the advertised purchase price?
Start by confirming exactly what the advertised price includes.
Ask the builder:
Is the advertised price inclusive of HST?
Does the price assume that I qualify for particular HST rebates?
What would the purchase price be if I did not qualify for one or more of those rebates?
Will the agreement clearly explain how HST and rebates are being handled?
Do not assume that the advertised price is the amount you will ultimately pay. Ask for a written breakdown so you understand the numbers before signing.
2. Which HST rebates or relief programs may apply to this purchase?
There are several HST rebate programs that may apply to a qualifying new home in Ontario. They have different eligibility requirements.
Depending on the purchase and your circumstances, these may include:
Ontario Enhanced New Housing Rebate (ENHR): Temporary enhanced provincial HST relief for eligible new homes purchased from a builder during the applicable period.
Ontario New Home Affordability Payment (ONHAP): A provincial payment that provides additional temporary relief on the federal portion of HST for eligible buyers who qualify for the applicable Ontario enhanced rebate.
Federal First-Time Home Buyers' GST/HST Rebate: A federal rebate for eligible first-time home buyers purchasing qualifying new homes.
Ontario First-Time Home Buyers' HST Rebate: An Ontario rebate for eligible first-time home buyers purchasing qualifying new homes.
These programs are not interchangeable, and not every buyer or purchase will qualify for each one.
Ask the builder which rebates have been included in the proposed price or statement of adjustments. You can also review eligibility with your real estate lawyer or a qualified tax professional.
3. Does the purchase agreement qualify based on the dates and other program requirements?
The temporary Ontario enhanced HST relief has specific timing requirements.
For qualifying purchases from a builder, the agreement generally must be entered into between April 1, 2026, and March 31, 2027. Other requirements apply, including construction deadlines and the intended use of the home.
Ask the builder:
Does my agreement fall within the required purchase-date period?
Does the builder expect the construction timeline to meet the program requirements?
Are there any special considerations if this is an assignment purchase or the agreement is amended?
What happens if the construction or closing timeline changes?
The date of an agreement is only one part of the eligibility test. Have your lawyer review the agreement and confirm how the program requirements apply to your particular purchase.
4. Do I need to live in the home to qualify?
Some new-home rebates are intended for homes used as the purchaser's or a qualifying relation's primary place of residence. Other rules may apply to rental properties.
Ask the builder:
Does the rebate being applied for require me to occupy the home as my primary residence?
Are there restrictions on renting the property?
What happens if my plans change before or after closing?
Are there additional requirements if more than one person is purchasing the home?
Be clear about how you intend to use the property. Do not assume that a rebate available to an owner-occupier will also apply to an investment or rental property.
5. What happens if I do not qualify for a rebate that has been included in the price?
This is one of the most important questions to ask.
A builder may include an anticipated rebate in the purchase price or credit it to you on closing. However, being offered a rebate credit does not automatically mean you qualify.
The Canada Revenue Agency states that buyers are responsible for ensuring they meet the eligibility requirements. If a buyer receives a rebate they are not entitled to, the buyer may have to repay it to the CRA.
There are also circumstances where the builder may be jointly and severally liable with the buyer. This applies where the builder knew, or ought to have known, that the buyer was not entitled to the rebate or that the amount credited was greater than the buyer's entitlement.
Ask the builder:
What happens if my rebate application is denied or the amount is reduced?
Could I be responsible for paying the difference?
How will any outstanding amount be handled at closing?
Is the rebate amount conditional on my meeting specific requirements?
Have your lawyer explain any clauses that make you responsible for repayment or additional costs.
6. Who applies for the rebates — the builder or the buyer?
The application process depends on how the builder handles the rebate.
If the builder pays or credits the applicable rebate to you, the builder generally submits the required application to the CRA after you and the builder complete the paperwork.
If the builder does not pay or credit the rebate, you may need to submit the application yourself.
Ask:
Which rebates will the builder pay or credit?
Which rebates, if any, will I need to claim myself?
When will the applications be submitted?
Will I receive copies of the completed forms and supporting documents?
Make sure the agreement and statement of adjustments clearly show which rebates have been credited. You should not submit a second claim for a rebate you have already received through the builder.
7. Which forms and documents will I need to complete?
For eligible new-home purchases from a builder, the CRA uses forms that include:
Form GST190: GST/HST New Housing Rebate Application for Houses Purchased from a Builder.
Form RC7190-ON: GST190 Ontario Rebate Schedule.
Other documents may be required depending on the rebate and application type.
If the builder is handling the rebate, you will generally complete the applicable paperwork with the builder, often around closing. The builder submits the application and required supporting documents to the CRA.
For ONHAP, the CRA can share the relevant information with the Province of Ontario if you provide the required consent. If you do not provide consent, you may need to give the required information directly to Ontario.
Ask the builder:
Which forms will I be required to sign?
When will I receive them?
Who is responsible for submitting each application?
Will I receive copies for my records?
Keep copies of your signed agreement, statement of adjustments, rebate forms and related correspondence.
8. How are upgrades, extras and other selections handled?
New-build purchases can include choices and additional costs beyond the base purchase price.
These may include:
Flooring, cabinetry and countertop upgrades
Appliance packages
Structural changes or additional features
Lot premiums
Additional parking or storage, where applicable
Ask the builder how these items are documented in your agreement and how they will be reflected in the final purchase price, HST calculation and statement of adjustments.
Do not assume that every upgrade or extra changes your eligibility for a rebate or the applicable price threshold. The treatment can depend on the details of the purchase and the relevant tax rules.
Have your real estate lawyer review the agreement and explain any effect these additional items may have on your costs.
9. What other closing costs or adjustments should I budget for?
Beyond the purchase price and HST, there may be other costs associated with buying a new home. The amounts and types of charges can vary by builder, development and property.
Depending on the agreement, possible items to ask about include:
Development charges or municipal levies
Utility connection or installation charges
Tarion enrolment fees
Legal fees and disbursements
Land transfer tax
Adjustments for property taxes or other prepaid expenses
Condominium-related fees or interim occupancy costs, if applicable
These charges do not apply in the same way to every purchase. Some may be included in the purchase price, capped, waived or payable separately.
Ask the builder for a written list of anticipated closing adjustments and any additional charges that could be payable. Have your lawyer review the agreement to identify which costs are fixed, which may change and whether any amounts are capped.
10. Has my lawyer reviewed the agreement before I sign?
A new-build purchase agreement can be lengthy and may contain important conditions about HST, rebates, closing costs, construction timelines, delays and adjustments.
Before signing, have a real estate lawyer experienced with new-build purchases review the agreement.
Ask your lawyer to help you understand:
How the purchase price and HST are calculated
Which rebates have been included or credited
What happens if you are not eligible for a rebate
Which closing costs and adjustments may apply
Your responsibilities for completing rebate applications
Any clauses that could create additional costs or obligations
It is much easier to ask questions and clarify the terms before signing than to discover unexpected costs later.

A Final Word
Buying a new build is an exciting milestone, but it is important to understand the financial details before committing to a purchase.
HST relief and rebate programs can make a meaningful difference for eligible buyers. However, the amount you may receive depends on the specific program requirements, the purchase agreement and your individual circumstances.
My advice is to ask questions early, get the details in writing and have your lawyer review the agreement before you sign. A little preparation can help you move forward with greater clarity and confidence.
