How Parents Can Help Children Buy a Home Without Jeopardizing Retirement

Can you gift your child a down payment in Canada? Yes — there’s no gift tax here, and lenders routinely accept gifted down payments from immediate family with a signed gift letter. The real question is whether you should, and how. Per CIBC Economics’ research on gifted down payments, roughly 31% of Canadian first-time buyers now receive family help, and the average gift has climbed to about $115,000 — real retirement capital, not pocket change. Done well, a gift can move your child from a $475,192 Durham condo to a $753,919 Bowmanville detached without touching your own retirement security. Done casually, the same gift can shortchange your final 15 years of retirement income and end up half-owned by an ex-son-in-law. Here’s the framework we use with Durham Region and Port Hope families — as planners first, and Realtors second.

The Short Answer: Five Steps Before Money Moves

• Stress-test your own retirement first — model your plan without the gifted amount and confirm it still works to age 95.
• Decide: gift or loan. They are treated completely differently by lenders and by family law.
• Paper it properly — a lender gift letter for a gift; a promissory note (and ideally a registered mortgage) for a loan.
• Protect the money from relationship breakdown — in Ontario, a gift that ends up in a matrimonial home generally loses its protection.
• Move funds early and traceably — lenders want the money seasoned in your child’s account with a clean paper trail before closing.

Gift vs. Loan: The Table That Prevents Family Fights

The lender point is the one families most often get wrong. Under OSFI’s Guideline B-20, federally regulated lenders must verify and document the source of a borrower’s down payment, and mortgage insurers like CMHC distinguish traditional down payment sources — savings and genuine gifts from immediate family — from borrowed funds. If the “gift” is secretly a loan, the gift letter both parties signed says otherwise, and that’s a misrepresentation to the lender. Decide honestly which one it is, then paper that reality.

How the Gift Letter Actually Works

Every lender has its own template, but all require the same declarations: the donor’s name and relationship (immediate family — parent, grandparent, or sibling — for most insured mortgages), the exact amount, the property address, and a signed statement that the funds are a genuine gift with no expectation of repaymentand no ownership claim on the property. Expect the lender to also want the paper trail: a bank statement showing the money leaving your account, the deposit landing in your child’s account — typically well before closing — and sometimes 90 days of history to satisfy anti-money-laundering rules. One practical tip from our mortgage practice: move the money in one clean transfer, not a series of e-transfers, and keep every confirmation.

Remember the gift doesn’t help your child qualify. They still pass the stress test on their own income. A $100,000 gift shrinks the mortgage but does not manufacture borrowing power — though on Whitby’s $894,257 July average (per the Toronto Regional Real Estate Board’s Market Watch), a bigger down payment is often exactly what bridges the qualification gap.

The Retirement Stress Test: What a $100,000 Gift Really Costs You

A $100,000 gift at age 60 is not $100,000 — it’s what that money would have become. Using FP Canada’s 2026 Projection Assumption Guidelines (6.3% for Canadian equities before fees), $100,000 left invested becomes roughly $460,000 by age 85 — our own calculation. Framed as income, at a 4% sustainable withdrawal it’s about $4,000 per year, indexed, for life.

That doesn’t make gifting wrong — it makes it a planning decision. The test we run: rebuild the retirement projection with the gift removed, at FP Canada assumptions, through age 95, with a long-term-care contingency in the final decade. If the plan still funds your lifestyle with margin, gift with a clear conscience. If it only works with average returns and no surprises, consider a smaller gift, a staged gift, or a loan. And think hard before funding a gift from a HELOC or reverse mortgage: you’d be paying interest so your child doesn’t have to, which is usually the worst seat at the table. Selling investments to fund a gift can also trigger capital gains tax on your side — the gift is tax-free, but getting the cash ready may not be.

Protecting the Gift: Marriage Contracts and the Matrimonial Home Trap

Ontario family law has a wrinkle every gifting parent should know. Gifts received during a marriage are normally excluded from a child’s net family property on divorce — but that exclusion is generally lost for value traceable into the matrimonial home, which is exactly where a down payment gift goes. Absent other protection, your gift can effectively be shared with your child’s ex-spouse.

The protections, in ascending order of strength: document the gift’s source and date; structure it as a documented loan with a promissory note (a debt reduces net family property regardless of the home); register that loan as a second mortgage on title; or have the couple sign a marriage contract (or cohabitation agreement) addressing the contribution, with independent legal advice on both sides. Awkward conversations — but in our experience, far less awkward than the alternative. This is legal territory: involve a family lawyer before closing, not after separation.

The Durham Math: What a Gift Actually Buys

Per TRREB’s July 2026 Market Watch, the average Durham Region home sold for $834,312 — Oshawa at $693,677, Clarington/Bowmanville at $753,919, Whitby at $894,257. A $75,000 gift on top of a child’s own $60,000 in savings turns a 5%-down condo purchase into roughly 20% down on an Oshawa detached — eliminating the CMHC premium and meaningfully cutting the monthly payment. It also pairs with everything your child can do themselves: the FHSA, the $60,000 RRSP Home Buyers’ Plan, and the first-time buyer land transfer tax refund we covered in our recent articles on the FHSA-vs-HBP-vs-TFSA decision and Ontario’s land transfer tax refunds. The most efficient family plans use the child’s registered accounts fully before sizing the parental gift.

Frequently Asked Questions

Is there tax on gifting my child money for a house in Canada? No — Canada has no gift tax, and your adult child pays no tax on receiving cash. But if you sell investments or property to raise the cash, you may owe capital gains tax on that sale, and any interest you charge on a family loan is taxable income to you.

Who can give a gifted down payment? For insured mortgages, most lenders and CMHC require the donor to be immediate family — typically a parent, grandparent, or sibling. A signed gift letter confirming no repayment is expected is mandatory, and lenders verify the transfer with bank records.

How much are parents typically gifting? Per CIBC Economics, about 31% of first-time buyers receive family help, and average gifts have grown to roughly $115,000 nationally — larger in the GTA, where prices are higher.

Should it be a gift or a loan? A gift is simpler with lenders and truly transfers the wealth; a loan preserves your claim and offers better protection if your child’s relationship breaks down, but can affect mortgage qualification. Never call a loan a gift on a lender’s form — decide, then document honestly.

Can I protect the gift if my child divorces? Partially. In Ontario, money traceable into the matrimonial home generally loses its gift exclusion. A documented loan, a registered mortgage, or a marriage contract provides real protection — talk to a family lawyer before the money moves.

One Plan, Both Generations

This decision sits at the intersection of our practice: your retirement plan, your child’s mortgage qualification, and the Durham home they’re trying to buy. We model all three together — the gift’s impact on your projections, the gift-vs-loan structure, and the purchase itself — so both generations sign with confidence.
