Gifting or Transferring an Ontario Property to Your Children: The Tax Rules and the Traps
Deemed disposition, land transfer tax, estate planning, and the three most common mistakes
Do I have to pay tax when I gift or transfer my Ontario home to my children?
In most cases, yes. Canadian tax law treats a gift as if you had sold the property at its fair market value (FMV) — a “deemed disposition.” If the home is not your principal residence, the gain is taxable in your hands; the principal residence exemption may shelter it. Separately, Ontario Land Transfer Tax (LTT) generally does not apply to a gift with no consideration, but if your child assumes the mortgage, LTT applies on that assumed amount.

I’m Arthur Zhao. Every year clients ask me the same thing: should I transfer the house to my kids now — to save tax and avoid a mess down the road? The instinct is understandable, but Canada taxes gifts in a way that surprises most people: the moment you give the property away, you may have already “sold” it for tax purposes. Here is how the three pieces fit together — CRA’s deemed disposition, Ontario’s land transfer tax, and the estate-planning risks hiding underneath.

Step 1: A "gift" is a "sale" in the eyes of the tax law
There is also a rule aimed squarely at family transfers: because you and your child do not deal at arm’s length, even a transfer for a token “one dollar” or a below-market price is treated by CRA as if the price were equal to fair market value. Selling low does not sidestep the deemed disposition.
Step 2: Work out exactly what the capital gain costs
One important clarification: the federal government had proposed raising the inclusion rate to two-thirds on gains above $250,000 per year, but that increase was cancelled (Government of Canada, Spring Economic Update 2026). The rate remains 50%. Because these rules do change, have an accountant confirm the rate for the actual year of your disposition before you act.
⚠️Rates and inclusion rules change. At the time of writing the capital gains inclusion rate is 50%, and the previously proposed two-thirds increase was cancelled — but have an accountant confirm the rules for the actual year you dispose of the property before relying on any number.
💡 The key point: if the home has been your principal residence throughout, the principal residence exemption may shelter all or most of the gain, so you may owe no capital gains tax on the gift. But per CRA (Canada.ca, 2025), only one property per family unit can be designated as a principal residence for any given tax year — using one home for the exemption means you cannot use another for the same years. Which property, and which years, get the exemption is a calculation, not a casual choice.
Step 3: Do not forget Ontario Land Transfer Tax (LTT)
In other words, a gift avoids LTT only when the property is free and clear of any mortgage or encumbrance, and the child is not assuming any debt or obligation in return.
ℹ️Tip: if the only goal is to reduce probate later, ask a lawyer whether there is a lower-risk route than adding a name now (a testamentary trust, beneficiary designations, and so on) — don’t trigger a capital gain today just to save a probate fee.
Step 4: The estate-planning angle — adding a name is not a free win
It sounds clean, but transferring part of the ownership today generally counts as a partial deemed disposition today — the Step 1 and Step 2 capital-gains math applies now, not later. It also exposes that share of the home to your child’s financial risks (next section). The probate fee you save may not be worth the tax you accelerate and the risk you take on.
The three most common — and most expensive — traps
Trap 1: Your child loses the principal residence exemption on their side. If your child already owns and lives in a home, transferring a second property to them puts two homes in their name. When they eventually sell the gifted one, the gain (measured from its FMV at the time of the gift) may not be sheltered — only one property per family unit qualifies each year (CRA, Canada.ca, 2025).
Trap 2: The capital gains surprise bill. Gift an investment property or a highly appreciated home, and the entire gain at the moment of deemed disposition lands in your income for that year, potentially pushing you into a higher bracket. Many families only discover this at tax time — owing real cash on a sale that produced no cash.
Trap 3: The home is exposed to your child’s creditors and divorce. Once the home is in your child’s name (or their name is on title), it can be pursued by their creditors or brought into property division if their marriage breaks down. A parent’s good intentions can be lost to a child’s business failure or divorce.
💡 So my advice is simple: gifting or transferring to a child is a tax + legal + family decision, not just signing a transfer document. Before you act, have an accountant run the deemed-disposition and principal-residence math at the current year’s rates, and have a real estate lawyer handle the land transfer tax, mortgage assumption, title structure, and creditor protection.

Frequently Asked Questions
Can I avoid capital gains tax by selling the house to my child for $1 or my original cost?
No. Because parent and child do not deal at arm’s length, CRA (Canada.ca, 2025) treats a below-market price as if it were equal to fair market value. A home you bought for $200,000 that is now worth $1,000,000 is taxed on the gain measured from $1,000,000, no matter what price you write on the transfer — and selling low can create a double-tax problem for your child later.
If I gift my principal residence to my child, do I owe tax?
If the home has been your principal residence throughout, the exemption may shelter all or most of the gain, so you may owe no capital gains tax on the gift. But only one property per family unit can be designated each year (CRA, Canada.ca, 2025), and your child now holds an extra property, which can have tax consequences for them later. Have an accountant run the numbers.
Do I pay Ontario land transfer tax if I gift a mortgaged home to my child?
Yes. Per the Ontario Ministry of Finance (Ontario.ca, 2025), only a gift with no consideration at all avoids LTT. Your child taking over the mortgage is assuming a liability, which is consideration, so LTT is payable on the outstanding mortgage balance at registration — parent-to-child transfers included.
Is it safe to add my child to title (joint tenancy)?
Be careful. Transferring part of the ownership now generally counts as a partial deemed disposition now, so the capital gain is calculated today. That share of the home is also exposed to your child’s creditors and to property division if they divorce. The probate fee you save may not be worth those costs — talk to a lawyer first.
Does Canada have an estate tax or gift tax?
No — there is no estate tax or gift tax federally or provincially. Ontario has an Estate Administration Tax (the probate fee), charged on the value of the estate. But “no estate tax” is not the same as “tax-free transfer”: the deemed-disposition capital gain and land transfer tax are the real items to plan for in advance.
