First-time home buyers in Canada are one step closer to a major tax break. Bill C-4, which eliminates the federal GST on newly constructed homes for eligible buyers, passed its final reading in the Senate on February 26, 2026.

The legislation now returns to the House of Commons for consideration of Senate amendments. After that, it needs Royal Assent to become law. Given the broad cross-party support the bill has received throughout its legislative journey, that final step could happen within days.

Here is what is in it, who qualifies, and how much you could actually save.

‍

What the Rebate Covers

Under the new provisions, first-time buyers purchasing newly built or substantially renovated homes priced at $1 million or less can recover the full 5% federal GST. That is a maximum rebate of $50,000 on a $1 million property.

This is a dramatic increase from the existing GST new housing rebate, which caps out at $6,300.

The program is not binary. Homes priced between $1 million and $1.5 million qualify for a partial rebate on a sliding scale. At $1.5 million, the first-time buyer rebate phases out entirely.

For context, if you bought a qualifying new home for $1.25 million, you would be eligible for 50% of the maximum rebate, or $25,000 in federal tax relief.

One important detail most coverage skips: this rebate is temporary. It applies to purchase agreements signed from March 19, 2025, through the end of 2030. It is not a permanent change to the tax code.

The rebate also applies only to new construction. If you are buying resale, which is the majority of transactions in most markets, none of this applies to you.

The Legislative Timeline

Bill C-4 was introduced in the House of Commons on June 5, 2025, during the first session of the 45th Parliament. It passed third reading in the House on December 11, 2025, and then moved to the Senate.

The Senate completed its review and passed the bill on February 26, 2026. The current status shows the bill at consideration in the House of Commons of amendments made by the Senate.

During committee review, an important change was made. The effective date was revised to apply to purchase agreements signed after March 19, 2025, rather than the originally proposed date of May 27, 2025. That backdating means buyers who signed contracts earlier in 2025 may already qualify.

Royal Assent is expected as early as the first week of March 2026. Once that happens, the Canada Revenue Agency will publish claim procedures and begin accepting applications.

Who Qualifies as a First-Time Buyer

The legislation defines a first-time buyer using a rolling four-year lookback. To qualify, you must not have occupied any home as your primary residence - in Canada or anywhere in the world - while owning it, at any point beginning from the start of the fourth calendar year preceding your purchase.

In plain terms: if you have not owned and lived in a principal residence for roughly the past four years, you likely qualify. The clock does not reset on January 1 of your purchase year the way some other programs calculate it. It runs back from the preceding calendar year.

Two eligibility requirements that matter for many buyers in BC and are absent from most coverage: you must be at least 18 years old, and you must be a Canadian citizen or permanent resident at the time of purchase. Those on work permits or study permits do not qualify, regardless of how long they have lived here.

If you are buying with a spouse or partner, both of you must independently meet the first-time buyer requirement. One qualifying, one not - the rebate is gone.

The home must be your principal residence. Investment properties do not qualify.

Ontario Could Stack Another Rebate on Top

Ontario has announced its own matching HST rebate for first-time buyers, but the math behind the $130,000 headline figure requires unpacking.

Ontario already has an existing HST New Housing Rebate that provides up to $24,000 in provincial tax relief for eligible buyers - this is already law and available now. The province has proposed a new additional rebate that would remove the remaining 8% provincial HST portion for first-time buyers on homes up to $1 million. Combined with the existing provincial rebate, that would total $80,000 in provincial relief.

Add the federal $50,000 and you get the $130,000 figure. But that number requires three things to be true simultaneously: Bill C-4 must receive Royal Assent, Ontario must pass its proposed legislation (which has not happened yet), and the buyer must qualify under both programs. As of now, Ontario's new rebate does not exist as law.

If you are buying in BC, the Ontario provincial rebate is irrelevant to you. The federal component is what matters here.

How This Fits With Other First-Time Buyer Programs

The GST rebate is one piece of a larger puzzle for first-time buyers in 2026.

The First Home Savings Account lets you contribute up to $8,000 annually, with a lifetime limit of $40,000 per person. Contributions are tax deductible, and withdrawals for a qualifying home purchase are tax free.

The RRSP Home Buyers' Plan allows you to withdraw up to $60,000 from your RRSP without paying tax on the withdrawal. For withdrawals made between January 1, 2022, and December 31, 2025, you get a three-year grace period before repayments begin.

Land transfer tax rebates exist in Ontario, British Columbia, and Prince Edward Island. In Toronto, where you pay both provincial and municipal land transfer tax, the combined rebate can exceed $8,000. In BC, the first-time buyer rebate on property transfer tax applies to homes under $500,000 with a partial rebate up to $525,000.

The First-Time Home Buyers' Tax Credit provides up to $1,500 to offset closing costs.

None of these programs require you to pick just one. A first-time buyer purchasing a new build could potentially stack the GST rebate, FHSA withdrawals, HBP withdrawals, provincial land transfer tax rebates, and the federal tax credit all on the same purchase.

What to Watch

The main thing is the final legislative step. Bill C-4 needs Royal Assent before the rebate becomes law. Once that happens, the CRA will need time to set up application systems.

If you signed a purchase agreement after March 19, 2025, for a new home under $1.5 million, you may already qualify - pending Royal Assent. If you are still shopping, this rebate changes the math on whether a new build makes sense compared to resale.

The maximum $50,000 savings applies at the $1 million price point. Below that, the math is simple: 5% of the purchase price. Above $1 million, the rebate scales down until it disappears at $1.5 million.

For first-time buyers who were already considering new construction, this is a significant reduction in transaction costs. For everyone else - and that is most buyers - it is a policy that does not touch your transaction, but signals where government attention is focused: getting new supply built and occupied.
