Buying a newly built home in Ontario has become more affordable thanks to the Ontario’s 2026 GST/HST Rebate Changes.

With housing affordability remaining one of the biggest challenges for Canadians, both the Ontario and federal governments introduced enhanced GST/HST relief to reduce the tax burden on qualifying new homes. The temporary program is designed to lower closing costs, encourage new home construction, and help more Canadians achieve homeownership.

Whether you’re purchasing your first home in Toronto, upgrading in Mississauga, investing in Ajax, or building a custom home in Ottawa, understanding these rebate changes could save you thousands of dollars.

This guide explains who qualifies, how the rebate works, and how you can maximize your savings.

What Are Ontario’s 2026 GST/HST Rebate Changes?

Understanding Ontario’s 2026 GST/HST Rebate Changes

Ontario’s 2026 GST/HST rebate changes temporarily expand the tax relief available on qualifying new homes purchased during the program period.

The enhanced program is intended to:

• Reduce the cost of buying a new home
• Increase housing affordability
• Encourage residential construction
• Support homebuyers across Ontario
• Help improve housing supply

The enhanced rebate combines relief for both the provincial and federal portions of HST for eligible buyers, with maximum savings of up to $130,000 for qualifying purchases.

Why These Changes Matter

The price of newly constructed homes has increased significantly across Ontario.

In major cities including:

• Toronto
• Mississauga
• Brampton
• Vaughan
• Markham
• Richmond Hill
• Oakville
• Burlington
• Milton
• Hamilton
• Ajax
• Pickering
• Whitby
• Oshawa

buyers often face substantial closing costs.

Reducing the GST/HST burden makes new construction more affordable while supporting the province’s long-term housing goals.

Who Can Benefit?

The enhanced rebate may benefit:

• First-time home buyers
• Existing homeowners purchasing a new principal residence
• Individuals building a custom home
• Eligible purchasers of newly constructed homes
• Certain investors purchasing qualifying rental housing under separate rules

The home generally must meet the applicable eligibility requirements established by the Canada Revenue Agency (CRA) and the Province of Ontario.

Ontario HST Rebate for First-Time Home Buyers

Many Canadians search for the Ontario HST rebate for first-time home buyers because tax savings can significantly reduce upfront costs.

If you qualify under the enhanced rules, the rebate can lower:

• Closing costs
• Total purchase price
• Mortgage amount required
• Monthly mortgage payments

Combined with the First Home Savings Account (FHSA), RRSP Home Buyers’ Plan (HBP), and Land Transfer Tax Rebates, the HST rebate can become an important part of your home-buying strategy.

7 Proven Steps to Maximize Your New Home Savings

1. Confirm Your Eligibility Before You Buy

Before signing an Agreement of Purchase and Sale, verify whether your purchase qualifies.

Important factors include:

• Type of property
• Purchase date
• Intended occupancy
• Purchase price
• Residency requirements

Understanding Ontario HST rebate eligibility early helps prevent costly surprises later.

2. Buy a Qualifying New Home

The rebate generally applies to:

• Newly constructed detached homes
• Semi-detached homes
• Townhouses
• Condominiums
• Newly built custom homes

Most resale homes do not qualify because HST generally does not apply to existing residential resale properties.

3. Understand the Purchase Price Thresholds

One of the biggest improvements in GST HST rebate Canada 2026 is the expanded relief for qualifying new homes.

Depending on the home’s purchase price and eligibility, buyers may receive significantly more tax relief than under previous rebate programs. The enhanced measures provide full relief for many qualifying homes up to specified value thresholds, with phased reductions for higher-priced homes.

4. Work with an Experienced Mortgage Broker

Buying a new home involves more than securing the lowest mortgage rate.

An experienced mortgage broker can help you:

• Estimate total closing costs
• Review rebate eligibility
• Structure financing
• Coordinate with your lawyer and builder
• Ensure rebates are properly considered in your financing plan

Professional advice often prevents expensive mistakes.

5. Understand Builder Rebate Assignments

Many builders apply the rebate directly at closing.

Instead of paying the full HST upfront and waiting for reimbursement, eligible purchasers often assign the rebate to the builder, who reduces the purchase price accordingly.

However, buyers remain responsible for ensuring they actually qualify. If they don’t meet the eligibility requirements, the CRA may require repayment.

6. Keep Every Important Document

Maintain copies of:

• Purchase agreement
• Builder invoices
• Closing documents
• Mortgage documents
• Legal paperwork
• Occupancy records

Good documentation makes the rebate process much easier if supporting information is requested.

7. Learn How to Claim Ontario HST Rebate

One of the most common questions is “How to claim Ontario HST rebate?”

The answer depends on how your purchase is structured.

In many builder transactions, the rebate is assigned directly to the builder and reflected in the final purchase price.

In other situations—such as owner-built homes or certain custom home projects—you may need to apply directly using CRA forms after construction is complete. The CRA provides specific forms and schedules for federal and Ontario rebate claims.

New Home HST Rebate Ontario: Example

Imagine purchasing a qualifying newly built home in Whitby for $950,000.

If your purchase meets the eligibility requirements under the enhanced program:

• Your HST burden may be substantially reduced.
• Your required mortgage amount could decrease.
• Your closing costs become more manageable.
• Your long-term borrowing costs may also be lower because you’re financing less.

The exact rebate depends on the purchase price, transaction structure, and applicable program rules.

Why This Matters for Ontario Homebuyers

The enhanced GST/HST rebate is especially valuable in higher-priced markets such as:

• Toronto
• Mississauga
• Vaughan
• Markham
• Oakville
• Richmond Hill
• Burlington
• Ajax
• Pickering
• Whitby
• Oshawa
• Ottawa
• Hamilton
• London
• Kitchener
• Waterloo

With new home prices often exceeding hundreds of thousands of dollars, even a partial tax reduction can translate into significant savings over the life of your mortgage.

Common Mistakes That Could Cost You Your Rebate

Although the enhanced GST/HST rebate can provide substantial savings, many buyers unintentionally make mistakes that delay or even eliminate their eligibility.

Avoid these common pitfalls:

1. Assuming Every New Home Qualifies

Not every newly built property automatically qualifies for the enhanced rebate. Eligibility depends on several factors, including the purchase date, home value, intended occupancy, and applicable government rules.

2. Not Reading the Purchase Agreement Carefully

Many builders include rebate assignments within the Agreement of Purchase and Sale. Buyers should understand exactly how the rebate is being applied before signing.

3. Missing Required Deadlines

Certain rebate applications have filing deadlines. Delays may reduce or eliminate your ability to claim available savings.

4. Keeping Poor Documentation

Save copies of:

• Purchase agreement
• Builder invoices
• Mortgage documents
• Lawyer’s Statement of Adjustments
• Occupancy documents
• Closing paperwork

Good records make the application process much smoother.

5. Not Consulting Mortgage and Tax Professionals

The rebate rules can vary depending on your situation. Working with an experienced mortgage broker, lawyer, and tax professional helps ensure you maximize every available benefit.

How the Rebate Can Affect Your Mortgage

Many buyers focus only on the rebate itself.

However, reducing the purchase cost can also improve your mortgage position.

Potential benefits include:

• Lower mortgage amount
• Reduced monthly payments
• Less interest paid over time
• Improved affordability
• Better debt-to-income ratios

For many Ontario buyers, these savings continue long after closing day.

Why First-Time Buyers Benefit the Most

The enhanced rebate is particularly valuable for first-time buyers.

When combined with other government programs, eligible buyers may benefit from:

• First Home Savings Account (FHSA)
• Home Buyers’ Plan (HBP)
• Ontario Land Transfer Tax Refund
• Toronto Municipal Land Transfer Tax Rebate (for eligible Toronto buyers)
• GST/HST rebate savings

Together, these programs can significantly reduce the upfront cost of purchasing a home.

Ontario Cities Where the Rebate Can Make the Biggest Difference

Housing prices remain high across much of Ontario, making tax savings even more valuable.

The enhanced rebate may be especially beneficial for buyers purchasing new homes in:

• Toronto
• Mississauga
• Brampton
• Vaughan
• Markham
• Richmond Hill
• Oakville
• Burlington
• Milton
• Hamilton
• Ajax
• Pickering
• Whitby
• Oshawa

• Cambridge
• Guelph
• Barrie
• Ottawa
• London
• St. Catharines
