Gifting or Transferring Assets in Canada: The Hidden Capital Gains Tax Traps

You want to give something of value to a child, a sibling, or a friend. In Canada, that generosity may come with a tax bill — and not from the recipient. The capital gains tax rules on gifts and transfers in Canada can make a well-intentioned transfer surprisingly costly, and the rules differ significantly depending on whether the recipient is your spouse, your adult child, or an unrelated person.

Understanding the tax implications before you transfer any capital property is not optional. Getting it wrong means the CRA comes back to the original owner for tax on a gain they may have already given away.

The Default Rule: Deemed Fair Market Value Proceeds

When you give away capital property, you are deemed to have received fair market value as your proceeds, even if you received nothing at all. This applies to:

• Gifts to adult children
• Gifts to siblings, parents, or other relatives
• Gifts to friends
• Donations of property to non-qualified recipients

Example: You own 500 shares you bought for $5,000 years ago. Today they are worth $22,000. You give them to your adult daughter. You are deemed to have sold them for $22,000. You report a capital gain of $17,000 on your tax return. Your daughter's ACB is $22,000 (the fair market value at the date of the gift).

The gift does not cost your daughter anything in tax — but it costs you a capital gains tax bill on the accrued appreciation.

The Spousal Rollover: The Key Exception

Transfers between spouses (and common-law partners) work differently. Under the spousal rollover, property transferred to a Canadian-resident spouse is automatically deemed to occur at the transferor's ACB — meaning no capital gain is triggered at the time of transfer. The gain is deferred until the spouse later sells the property (or dies).

This rollover applies automatically unless you elect out of it. Why would you elect out? If you have capital losses in the year and want to crystallise a gain to use them, or if both spouses are in very different tax brackets and careful planning is warranted, electing out can sometimes make sense. Your accountant can advise.

The spousal rollover also applies to transfers on death to a surviving spouse or qualifying spousal trust — see our article on deemed disposition.

Attribution Rules: The Anti-Income-Splitting Mechanism

Even after a rollover or below-market transfer to a family member, the attribution rules in the Income Tax Act may attribute income — and in some cases gains — back to the transferor for tax purposes.

Attribution of Income (Dividends and Interest)

If you transfer property to your spouse or minor child and they earn income from that property (dividends, interest, rental income), that income is attributed back to you and taxed in your hands. This prevents income-splitting by simply moving assets to a family member in a lower tax bracket.

Attribution of Capital Gains (Spouses)

Capital gains on property transferred to a spouse are also attributed back to the transferring spouse, as long as the spouses are still together. This is important: even if you gave the shares to your spouse years ago, if they sell them while you are still married (or living together), the capital gain is attributed back to you.

Attribution to a spouse continues until the marriage breaks down or the couple separates.

Attribution to Minor Children: Different Rule for Gains

Attribution of capital gains does not apply to transfers to minor children in most cases (unlike income attribution). When a minor child sells the gifted property, the capital gain is generally taxed in their hands. However, income (dividends, interest) earned on the gifted property is still attributed back to the parent until the child turns 18.

The "Loan at Prescribed Rate" Strategy

Attribution rules can be legally avoided using a prescribed rate loan. Instead of gifting property outright to a spouse or minor, you lend money to them at the CRA's prescribed interest rate (set quarterly and historically quite low). If the spouse or family trust invests the loan proceeds and earns a return above the prescribed rate, the excess is taxed in the lower-income family member's hands — without attribution.

This is a widely used income-splitting strategy, but it requires proper documentation: a written loan agreement, payment of interest each year by January 31, and correct reporting. An accountant sets up the mechanics; a lawyer can document the loan.

Donating Capital Property to Charity

If you donate publicly traded securities directly to a qualified donee (registered charity), you get a special deal: the capital gain on the donated securities is reduced to zero (no inclusion in income), and you receive a donation receipt for the full fair market value. This is significantly more tax-efficient than selling the securities and donating the cash, because in the latter scenario you pay tax on the gain first.

This incentive applies to publicly traded shares, bonds, ETFs, mutual fund units, and certain other property donated directly. It does not apply to property sold first and then donated. Coordinate with the charity to transfer securities directly.

Transferring Property on Relationship Breakdown

When spouses separate, property transferred under a written separation agreement or court order generally rolls over at ACB, like the spousal rollover — even after separation. This prevents the transfer of appreciated property from triggering a tax event in the middle of an already difficult situation. The recipient spouse acquires the property at the transferor's ACB and will pay the deferred gain when they eventually sell.
