The 90-Day Rule That Lets Separated Ontarians Qualify as First-Time Buyers Again
A 32-year-old nurse in Hamilton moved out of her matrimonial home in October 2025. By February 2026, she had a signed separation agreement and a pre-approval to buy a two-bedroom condo on her own. The lender told her she qualified as a first-time buyer for the Home Buyers' Plan, the First Home Savings Account, and a 30-year amortization. She had owned a home with her ex-husband for six years. None of that mattered.
The reason is a federal rule most people don't know exists.
The Four-Year Lookback and How It Resets
First-time buyer status in Canada is not permanent. It operates on a rolling four-year window. The Canada Revenue Agency defines a first-time buyer as someone who has not owned and occupied a home as their principal residence during the period beginning January 1 of the fourth year before the year of purchase and ending 31 days before the purchase date.
If you bought a house in 2018, lived in it through 2021, and sold in 2022, you would re-qualify as a first-time buyer by January 1, 2026. The clock resets not when you sell, but when you stop living in a home you own.
This matters for three federal programs: the Home Buyers' Plan (which allows you to withdraw up to $60,000 from your RRSP tax-free), the First Home Savings Account (which lets you contribute $8,000 annually up to a $40,000 lifetime maximum), and the 30-year insured mortgage amortization now available to all first-time buyers purchasing any home, new or resale.
The Separation Exception: 90 Days and You're Back In
The four-year rule has an override. If you are separated or divorced, you can re-qualify as a first-time buyer immediately, without waiting four years, if you meet two conditions.
First, you must have been living separate and apart from your spouse or common-law partner for at least 90 consecutive days due to a breakdown of the relationship. The 90 days are measured backward from the date you intend to make your Home Buyers' Plan withdrawal or FHSA contribution. Moving out in late December versus early January can shift your eligibility by an entire calendar year, because the FHSA lookback is based on calendar years, not rolling days.
Second, if you are using the Home Buyers' Plan, you must dispose of your interest in the former matrimonial home within two years of the withdrawal. Disposal means you either sell your share or buy out your ex-partner's share. If you are staying in the home and buying out the other party, you can still use the HBP, but the CRA will verify that the transaction legally transferred the other spouse's interest to you.
The separation exception applies to the HBP and the FHSA. It also allows you to access the 30-year amortization, which can reduce monthly payments by several hundred dollars on a single income. For a $500,000 mortgage at 5.5%, the difference between a 25-year and a 30-year amortization is roughly $280 per month.
Where Ontario Diverges: The Land Transfer Tax Trap
The federal programs are generous to separated buyers. Ontario's Land Transfer Tax rebate is not.
The Ontario rebate, worth up to $4,000, is available only to buyers who have never owned a home anywhere in the world at any time. The provincial definition does not include a separation exception. If you owned a condo in 2015, even if you have been separated for three years and meet every federal first-time buyer test, Ontario will not refund the tax.
Toronto has its own municipal Land Transfer Tax, with a separate rebate worth up to $4,475. The municipal rebate follows the same restrictive rule as the provincial one. Most separated buyers qualify for the federal benefits and neither of the LTT rebates.
The Spousal Exclusion No One Mentions
You can meet the 90-day rule, dispose of the old home, and still fail to qualify as a first-time buyer if your new spouse or common-law partner owns a home that you move into. The FHSA and HBP both disqualify you if your current partner owns and occupies a principal residence in the year you make your claim, even if you personally have not owned a home in a decade. The programs care about household ownership, not just individual history.
This catches people who remarry or move in with a homeowner partner between the separation and the purchase. The solution is to wait until after you have made your FHSA contribution or HBP withdrawal before cohabiting in a home the new partner owns.
The separation provisions exist because the tax system recognizes that a post-divorce purchase is economically similar to a first purchase. The 90-day rule is the threshold. Once you cross it, the federal system treats you as if the prior ownership never happened. Ontario does not.
