Most grandparents assume that leaving money to their grandchildren is a straightforward act of generosity. Write it into the will and it gets there. The reality is more complicated, and the tax exposure along the way is significant enough that without some planning, a meaningful portion of what you intended to leave can end up with the CRA before it ever reaches the people you wanted to give it to.
The good news is there are clear, well-established strategies that reduce or eliminate that exposure. The key is understanding which accounts and tools work in your favour, and which ones quietly create problems.
The biggest tax hit most people don’t see coming
The single largest tax risk for grandchildren inheriting wealth is an RRSP or RRIF.
When you die, the CRA treats the full remaining balance of your RRSP or RRIF as income on your final tax return. That amount gets added to whatever else you earned that year and taxed accordingly. For a large registered balance, that can mean a terminal tax bill at the top marginal rate (over 50% combined federal and provincial in Ontario) before anyone receives a dollar.
There is one important exception: if your spouse or common-law partner is named as the beneficiary, the RRSP or RRIF transfers to them on a tax-deferred basis. They absorb it into their own plan and the tax is deferred until they withdraw or pass away themselves.
For grandchildren, no such rollover exists. The estate pays the tax first. Only what remains after that gets through.
This is one of the reasons the RRSP meltdown strategy matters beyond just managing taxes in retirement. Drawing down your registered accounts in a controlled way during your lifetime directly reduces the balance sitting in that account when you die, which means a smaller terminal tax bill and more of your estate actually reaching the people you intended to leave it to.
Your TFSA is the cleanest account to pass on
Unlike an RRSP or RRIF, your TFSA does not create a terminal tax bill when you die.
If you name a grandchild as the direct beneficiary of your TFSA, the value of the account at your date of death passes to them tax-free and outside your estate entirely. It does not go through probate. It does not show up on your final tax return. In Ontario, that also means no estate administration tax on that amount (1.5% on every dollar above $50,000).
One detail worth knowing: any income the TFSA earns after your death while the estate is being settled may be taxable to the beneficiary. In practice this is usually a small amount over a short window, but it is worth being aware of.
The practical takeaway is simple. Keep your TFSA beneficiary designation current and make sure it names a person, not “my estate.” With cumulative TFSA room at $109,000 in 2026, a well-funded TFSA is a genuinely significant tax-free asset to leave behind.
Life insurance: tax-free, probate-free, no waiting
Life insurance with a named beneficiary is one of the cleanest wealth transfer tools available.
The death benefit pays directly to the named grandchild (or a trust set up on their behalf), bypasses your estate entirely, arrives tax-free, and is not subject to probate fees. No waiting on the estate to be settled. No CRA involvement. No court process.
For grandparents who have already maximized their registered accounts and want a dedicated vehicle to pass a specific amount to grandchildren, a permanent life insurance policy (whole life or universal life) can make a lot of sense. Premiums are paid with after-tax dollars, but the growth inside the policy is tax-sheltered and the death benefit is completely tax-free to the recipient.
It is not the right tool for everyone, and the structure matters. But for those it fits, it is hard to beat for clean, efficient wealth transfer across generations.
The RESP: the dedicated education vehicle
If the goal is to support a grandchild’s education specifically, the Registered Education Savings Plan is the most direct tool available.
Grandparents can open an RESP with a grandchild as the beneficiary, or simply contribute to an existing one the parents have already started. Either way, the federal government adds a 20% Canada Education Savings Grant on the first $2,500 contributed per year per beneficiary. That is $500 of free money annually, up to a lifetime maximum of $7,200 per child. The contribution limit across all plans for the same beneficiary is $50,000 lifetime.
The money grows inside the plan tax-sheltered. When the grandchild withdraws it for post-secondary education, the growth and government grants are taxed in the student’s hands, typically at a very low rate since most full-time students have little other income.
One thing worth coordinating before you open a separate RESP as a grandparent: if the parents already have a family RESP in place, all contributions to all plans for the same child count toward the $50,000 lifetime limit. The CESG is also calculated across all plans. Talk to the parents first to avoid accidentally triggering an over-contribution.
If the grandchild ultimately does not pursue post-secondary education, your contributions come back to you without tax. The government grants are returned to the government. The accumulated investment growth becomes what is called an Accumulated Income Payment, which is taxed as regular income plus a 20% penalty unless you have RRSP room available to shelter up to $50,000 of it.
In-trust accounts: useful, but with real limits
Some grandparents set up informal investment accounts in trust for grandchildren, particularly for goals outside of education. These can work, but there is a tax rule most people are not aware of.
Any interest or dividend income earned on money you give to a minor grandchild is attributed back to you for tax purposes. You pay tax on it, not the grandchild, until they turn 18. This is one of the attribution rules under the Income Tax Act that applies to transfers to related minors.
Capital gains are treated differently. Growth realized as capital gains inside the account can generally be taxed in the grandchild’s hands, not yours, even while they are a minor. That makes growth-oriented investments more appropriate inside these accounts than ones that primarily generate dividends or interest.
Once the grandchild turns 18, attribution stops and all income and gains are taxed in their hands going forward.
The rules here are more technical than they appear on the surface. If you are considering an in-trust account, work with an advisor to structure the investments inside it properly so you actually get the intended result.
Your will matters more than most people think
Leaving money to a grandchild through your will sounds simple. For adult grandchildren, it can be. For minor grandchildren, leaving a large lump sum without any structure around it is rarely what people actually intended.
A 12-year-old inheriting $200,000 outright would legally receive control of that money at 18 in most provinces. That may not align with what you had in mind.
A testamentary trust (a trust created inside your will) lets you set conditions. The funds are held and managed by a trustee and distributed to the grandchild at ages or milestones you define. For example, one third at 25, one third at 30, and the remainder at 35. You decide the terms.
One thing worth knowing: testamentary trusts are generally taxed at the top marginal rate after the first 36 months of the estate’s administration. During the Graduated Rate Estate period (those first 36 months), graduated tax rates apply, which can create some planning opportunity in that window. After that, the top rate applies.
If a grandchild has a disability, a Henson trust is worth knowing about. It is a fully discretionary trust structured so that the assets inside it do not disqualify the grandchild from means-tested government disability benefits like ODSP in Ontario. This is a specialized area of estate planning that requires legal advice specific to your province, but for families with a disabled beneficiary it is one of the most important tools available.
Giving while you are alive often beats giving at death
Canada has no gift tax. There is no limit to what you can give a grandchild during your lifetime, and gifts are not taxable income to the recipient.
Giving during your lifetime avoids probate fees on that amount, reduces the size of your taxable estate, and lets you see the impact of your generosity in real time. The attribution rules still apply for minor grandchildren on income from gifted funds, but capital gains, as discussed above, can generally be taxed in their hands.
For grandchildren who are already adults, the transfer is clean. Give them money and it is theirs, with no attribution and no gift tax.
One practical note: make sure your own retirement plan is fully funded before you start giving significant amounts away. The best financial gift you can give your grandchildren is not needing financial support from their parents later in your life. Your security comes first.
What to avoid
Adding a grandchild’s name to the title of your home or a major investment account to reduce probate exposure is a strategy that tends to create more problems than it solves.
The Supreme Court of Canada confirmed in Pecore v. Pecore (2007) that when a parent or grandparent adds an independent adult as a joint owner, the law presumes the asset is held in trust for the original owner’s estate, not as a genuine gift, unless there is clear documented evidence of intent to transfer beneficial ownership. The probate protection you were counting on may not hold up.
Beyond the legal uncertainty, adding a grandchild to a property title can trigger a deemed disposition and immediate capital gains tax. It exposes the asset to the grandchild’s creditors and potential future divorce proceedings. And it removes your ability to sell or refinance without their cooperation. For most families, the risks significantly outweigh the probate savings.
The bottom line
The families that pass wealth to grandchildren most efficiently are not the ones who simply wrote a will and assumed it would work out. They are the ones who used the right accounts for the right purposes, drew down taxable registered balances during retirement to reduce the terminal tax hit, kept beneficiary designations current, and built a will that included proper structure for minor beneficiaries.
None of this is complicated in isolation. But the pieces interact in ways that make it worth working through with an advisor who understands both retirement income planning and estate planning together, not as two separate conversations. The decisions you make in retirement about how to draw down your accounts directly affect what your grandchildren actually receive. Getting both sides of that picture right is what makes the difference.
