New Construction Condos Ottawa: GST Rebate Guide 2026

Ontario’s enhanced GST/HST rebate for first-time home buyers now makes new construction condos more accessible than ever. With potential savings of up to $50,000, the rebate can be the difference between affording a new-build condo or settling for resale. Condo613 breaks down everything you need to know about claiming this benefit in 2026.

Understanding the 2026 GST Rebate Changes

As of January 2026, the first-time home buyer GST rebate was significantly expanded:

• Properties valued up to $1 million now qualify for the rebate
• Eligible buyers can recover up to 100% of the federal GST (or the federal portion of HST)
• The provincial portion is covered by Ontario, meaning full GST/HST relief on qualifying purchases
• Potential savings of up to $50,000 on a $1 million new condo

Am I Eligible for the GST Rebate?

To qualify for the first-time buyer GST rebate on a new construction condo in Ottawa, you must meet these criteria:

• First-time buyer: You (and your spouse/partner) have never owned a principal residence anywhere in the world
• Property value: The new condo must be valued at $1 million or less
• Intention to occupy: You must plan to occupy the condo as your principal residence within a reasonable time
• Legal occupancy: The condo must be a newly constructed or substantially renovated unit purchased from a developer

How to Calculate Your Savings

The GST is 5% on new construction. For a $450,000 new condo:

• GST payable: $22,500
• Maximum federal rebate: Up to $22,500 (100% for properties under $350,000, declining to $0 at $450,000+)
• Ontario provincial rebate: Covers the remaining 8% provincial HST portion for eligible buyers

With the 2026 enhancements, a $450,000 new condo could see full GST/HST savings of approximately $36,000 — a substantial down payment boost.

New Construction Condo Developments in Ottawa

Several new condo developments in Ottawa qualify for the GST rebate in 2026:

Kanata North

Kanata North is seeing significant new condo construction, driven by tech sector growth and new zoning that allows greater density. New developments here typically range from $400,000 to $550,000, well within the $1 million threshold.

Barrhaven

Barrhaven continues to expand with family-oriented condo developments. Prices start in the high $300s, making this area particularly attractive for first-time buyers after the rebate.

Downtown Ottawa

New condo towers in the downtown core offer premium pricing ($500,000+), but the rebate still applies. For those working in the core, these units offer walkability that suburbs cannot match.

How to Claim Your GST Rebate

The rebate is claimed through the Canada Revenue Agency (CRA) using Form GST/HST RC4024, or directly through your real estate lawyer who can coordinate with the developer. Key steps:

1. Sign the agreement of purchase and sale with the developer
2. Complete the GST/HST new housing rebate application
3. Submit through your lawyer or directly to CRA within two years of closing
4. Receive the rebate as a direct deposit or cheque

Frequently Asked Questions

How much can I save with the GST rebate on a new condo in Ottawa?

Eligible first-time buyers can save up to $50,000 on new construction condos valued at $1 million or less. The actual amount depends on your purchase price — the rebate covers 100% of federal GST on properties under approximately $350,000.

Do I need to be a first-time buyer to get the GST rebate?

Yes. You and your spouse or partner must not have owned a principal residence anywhere in the world at any time. This applies regardless of whether you previously claimed the rebate.

Can I combine the GST rebate with other Ontario buyer incentives?

Yes. The GST rebate can be combined with the Ontario Land Transfer Tax rebate (up to $4,000) and the first-time home buyers’ savings account (up to $40,000 in tax-free withdrawals). However, it cannot be combined with the Canada Mortgage and Housing Corporation’s First-Time Home Buyer Incentive in most cases.
