Estate Planning for a Beneficiary With a Disability in Canada

Important Disclosure — Scope of Advice: This article is general information about estate planning for a beneficiary with a disability in Canada and is not legal, financial, or tax advice. The interaction between an inheritance and means-tested provincial disability benefits is technical and varies by province. Tools such as Henson trusts and Registered Disability Savings Plans must be established and coordinated correctly to achieve their intended protection. This planning can only be assessed individually. Consult a lawyer experienced in planning for beneficiaries with disabilities, and, in Quebec, a notary, coordinated with financial and tax advice.

For a parent or family member of someone with a disability, few questions weigh more heavily than this one: how do I make sure my loved one is provided for after I’m gone? It is a question asked out of deep love and a very real concern — and it is one where the ordinary approach to leaving an inheritance can, heartbreakingly, do more harm than good. Here is the difficulty that catches so many families off guard: leaving money directly to a family member with a disability, in the natural way most people leave an inheritance, can actually jeopardize the very supports that person depends on. Many provincial disability benefits are means-tested, and an outright inheritance can reduce or even eliminate them, so a gift meant to improve a loved one’s life can inadvertently undermine their stability. The good news — and it is genuinely good news — is that this problem is well understood, and Canadian law provides established, effective tools designed precisely to solve it. With the right planning, a family can provide meaningfully for a member with a disability while fully protecting their benefits. This article explains the problem clearly, then walks through the main solutions — the Henson trust and the Registered Disability Savings Plan — how they work together, why provincial differences matter, and how Quebec fits in. The aim is to replace worry with understanding, so that this most important act of care can be done right.

The Problem: Why an Outright Inheritance Can Backfire

Let’s begin with the problem, clearly stated, because understanding it is what makes the solutions make sense. It is a problem rooted in how disability supports are structured in Canada, and it is entirely counterintuitive to most people.

Many of the disability support programs that people rely on are provincial, and many of them are means-tested — meaning eligibility depends partly on the person’s assets and income. These programs are designed to support people whose resources fall below certain thresholds. Now consider what happens when someone receiving these supports inherits money or property in the ordinary way, left to them directly in a will. That inheritance is generally counted as the person’s asset or income. If it pushes them above the program’s thresholds, it can reduce their benefits or disqualify them entirely. And critically, the loss is often not just the monthly income support — many programs come bundled with other important supports, such as coverage for certain medications, medical needs, or housing assistance, which can be lost along with the income benefit. So the person can end up losing stable, lifelong supports and the linked benefits that go with them, replaced by a lump sum that, however generous, will eventually be spent — after which they must requalify for benefits, often a difficult process. The result is deeply unfair to the intention behind the gift: a parent who worked hard to leave something for their child with a disability can, without knowing it, leave that child worse off than if they had left nothing at all. This is the heartbreak that proper planning exists to prevent. It is not a reason to leave nothing — far from it. It is a reason to leave it in the right way. And that is precisely what the tools described next are designed to do: allow a family to provide generously while keeping the person’s benefits fully intact. Understanding the problem is the first step; the solutions follow naturally from it.

The Henson Trust: The Central Tool

The most important tool for this situation is a particular kind of trust, commonly known as a Henson trust. Understanding how it works — and why it works — is central to planning well for a beneficiary with a disability.

A Henson trust is a trust designed to benefit a person with a disability without the trust’s assets being counted as the beneficiary’s own assets for benefit-eligibility purposes. The key to how it achieves this lies in one defining feature: the trustee has absolute discretion over whether, when, and how much to distribute to the beneficiary. The beneficiary has no automatic right to demand the funds — they cannot compel the trustee to pay out. This matters enormously, because it is precisely the beneficiary’s lack of control over the assets that generally keeps those assets from being counted as theirs when their benefit eligibility is assessed. The funds sit in the trust, managed by the trustee, and can be used at the trustee’s discretion to enhance the beneficiary’s quality of life in ways that go beyond what basic benefits cover — things that make life richer and more comfortable, while the essential benefits and their linked supports remain intact. This is the elegance of the arrangement: the person keeps their benefits and also has access, through the trustee, to additional resources that improve their life. A few important points deserve emphasis. The trust takes its name from a Canadian legal case, and while the concept is well established, its treatment is not identical across the country — some provinces recognize and accommodate Henson trusts more clearly than others, and the details of the applicable provincial rules matter greatly. The choice of trustee is also crucial, because that person or institution will exercise judgment on behalf of the beneficiary, potentially for decades. And the trust must be drafted correctly — an improperly structured trust may fail to provide the protection intended, which is the entire point. For all these reasons, a Henson trust is not a do-it-yourself project; it must be established with a lawyer experienced in this specialized area. Done properly, though, it is a genuinely powerful way to care for a loved one with a disability.

The RDSP: A Powerful Companion Tool

Alongside the Henson trust sits another important tool, one created specifically to help build financial security for people with disabilities: the Registered Disability Savings Plan, or RDSP. Understanding how it complements a trust rounds out the picture.

The RDSP is a federal registered savings plan available to a person who qualifies for the Disability Tax Credit. It is designed to build long-term financial security, and it has some genuinely valuable features. Contributions grow on a tax-deferred basis, and — importantly — the plan can attract government grants that add to what the family contributes, and, in lower-income situations, government bonds that add funds even without family contributions. This makes the RDSP an unusually powerful long-term savings vehicle, because the government support can substantially boost what is set aside. For benefit-eligibility purposes, RDSP assets and withdrawals are, in most provinces, treated favourably and generally do not reduce provincial disability benefits — though, as with everything in this area, the exact treatment should be confirmed for the specific province. In estate planning, the RDSP is typically used together with a Henson trust rather than as a replacement for one, because the two do different jobs. The RDSP is excellent for long-term, government-supported accumulation, but it has contribution rules, rules governing the grants and bonds, and rules about withdrawals — including provisions about what happens if money is taken out earlier than intended, which can require repaying some government contributions. A Henson trust, by contrast, offers flexibility, can hold a wider range and larger amount of assets, and provides discretion. Used together, they can be complementary: the RDSP building government-supported savings over time, the trust providing flexible additional resources. Because coordinating an RDSP with a trust and with the overall estate plan involves both federal RDSP rules and provincial benefit rules, this is another area for professional guidance from advisors who understand both. Understood and used correctly, the RDSP is a valuable part of providing for a loved one with a disability.

Coordinating the Pieces — and Choosing a Trustee

Having looked at the tools individually, it’s worth stepping back to see how they fit together into a coordinated plan, because the pieces work best in concert, and one decision in particular — the choice of trustee — deserves real thought.

A well-designed plan for a beneficiary with a disability usually combines several elements. The will directs that the intended inheritance flow into a properly structured trust rather than to the beneficiary outright. That trust — often a Henson trust with absolute discretion — holds and manages the funds to enhance the beneficiary’s life without displacing their benefits. An RDSP may be established and funded to build long-term, government-supported savings. And these are coordinated so they work together rather than at cross purposes, with attention to the specific provincial benefit rules that govern the beneficiary’s supports. Life insurance is sometimes used as a means of funding such a trust, providing a sum on death that flows into the trust for the beneficiary’s long-term benefit; whether that fits depends entirely on the family’s circumstances and should be considered as one option among several with appropriate advice. Running through all of this is the choice of trustee, which cannot be overstated in importance. The trustee will exercise discretion on behalf of a vulnerable person, potentially for many years or decades. They must be trustworthy, capable of managing funds prudently, willing to take on a long-term responsibility, and sensitive to the beneficiary’s needs and dignity. Some families choose a trusted individual; some choose a professional or institutional trustee; some use a combination. There is no single right answer, but the decision deserves careful thought, because the trust is only as good as the person administering it. The overarching point is that this is coordinated, specialized planning — not a single document but an arrangement of pieces working together, tailored to the individual and their province. That is why it must be built with professionals who do this work, so that every piece fits and the protection actually holds.

A Note on Quebec and Provincial Variation

Because so much of this depends on provincial rules, a word on variation generally, and on Quebec specifically, is essential — perhaps more so here than in almost any other area of estate planning.

Two layers of provincial variation matter. First, the disability benefit programs themselves are provincial, and their means-testing rules — including how they treat trusts, inheritances, and RDSPs — differ from province to province. What protects benefits in one province may work differently in another, so the plan must be built around the specific rules of the province where the beneficiary lives. Second, the legal treatment of the tools varies: the recognition and handling of a Henson trust is not uniform across the country, which is another reason the planning must be province-specific. Quebec adds a further and important dimension, because it operates under civil law rather than common law. The concept of a trust exists in Quebec — the Civil Code provides for it — but Quebec’s law of trusts, its estate framework, and its disability support programs all follow Quebec’s own rules, which differ from the common-law provinces. A trust structure or strategy described for common-law Canada cannot be assumed to work the same way, or in the same form, in Quebec. Quebec residents planning for a family member with a disability need advice grounded specifically in Quebec law — from a notary or lawyer familiar with both Quebec’s trust and estate framework and Quebec’s disability support programs. The RDSP, being a federal plan, is available across the country including Quebec, but how it interacts with Quebec’s provincial supports still needs to be confirmed locally. The essential takeaway is the same everywhere but especially pointed here: this is specialized, jurisdiction-specific planning, and general guidance is no substitute for advice grounded in the beneficiary’s own province.

Common Mistakes to Avoid

Because this is specialized territory where good intentions can go wrong, it helps to name the mistakes families most often make, so they can be avoided. Each one is understandable, and each one can undo the very protection a family is trying to provide.

The first and most consequential mistake is simply leaving the inheritance outright — naming the family member with a disability directly in the will, as one naturally would for any other child. As we’ve seen, this is precisely what can jeopardize their means-tested benefits, and it is the error proper planning exists to prevent. A second, surprisingly common mistake is the informal arrangement: leaving the money to a sibling or other relative with the understanding that they will “look after” the person with a disability. This is fraught with problems — the money legally belongs to the sibling, so it is exposed to that sibling’s own creditors, marriage breakdown, or death; there is no legal obligation to use it for the intended person; and it can strain family relationships. What feels like a simple, trusting solution is actually one of the riskiest. A third mistake is a poorly drafted trust — a trust that does not give the trustee genuine absolute discretion, or that is not structured to meet the specific provincial rules, may fail to protect benefits despite the family’s best efforts, which is why the drafting must be done properly. A fourth is naming the person directly as the beneficiary of a registered plan or a life insurance policy without considering the benefit consequences, since proceeds paid directly to them can raise the same problem as an outright inheritance; where a trust is being used, the arrangement needs to be coordinated so that assets flow into the trust rather than to the person directly. A fifth is failing to keep the plan current, since benefit rules, family circumstances, and the beneficiary’s situation can all change over time. None of these mistakes is made out of anything but love, which is exactly why they are worth flagging — good intentions are not enough here; the structure has to be right. Avoiding these pitfalls is largely a matter of working with someone who does this planning regularly and knows where the traps lie. That expertise is what turns a loving intention into a plan that actually holds.

What to Do With This

So where does this leave a family wanting to provide for a loved one with a disability? In a hopeful place, because the central message is reassuring: this problem is solvable, and the tools to solve it are well established. The key is to plan deliberately and with the right help.

The first thing to take away is what not to do: do not leave an inheritance directly to a family member with a disability who relies on means-tested benefits, because doing so can jeopardize those benefits and leave them worse off. The second is that you do not have to leave less — you simply need to leave it in the right structure. With proper planning, you can provide generously while keeping every benefit intact. The tools are there: a properly structured trust, often a Henson trust with absolute discretion, to hold the inheritance; an RDSP to build long-term, government-supported savings; careful choice of a trustee who will serve the beneficiary well over the long term; and coordination of all of it with your overall estate plan and the specific rules of your province. Because this is genuinely technical, varies by province, differs in Quebec, and carries real consequences if done incorrectly, it is essential to work with a lawyer experienced specifically in planning for beneficiaries with disabilities — in Quebec, a notary — coordinated with financial and tax advice. This is not an area for shortcuts or generic templates; the stakes for your loved one are too high, and the rules too particular. But approached properly, it offers something deeply reassuring: the confidence that the person you love will be cared for, their benefits protected and their life enriched, long after you are able to be there yourself. That peace of mind is worth the effort of planning it well.

Frequently Asked Questions

Why can leaving an inheritance directly to a person with a disability cause problems?
Because many provincial disability supports are means-tested — eligibility depends partly on the person’s assets and income. An outright inheritance can be counted as an asset or income and may reduce or eliminate eligibility, including not just monthly income support but linked supports like certain medical, drug, or housing benefits tied to the program. So a well-meant inheritance left the ordinary way can leave a person with a disability worse off overall, replacing stable lifelong supports with a lump sum that eventually runs out. This is one of the most important, least understood issues in estate planning for these families. The good news: Canadian law provides established tools — a properly structured Henson trust and the RDSP — that let a family provide without jeopardizing benefits. But the rules are technical, vary by province, and must be set up correctly, so specialized legal advice is essential. General information, not legal or financial advice.

What is a Henson trust?
A trust used to benefit a person with a disability without disqualifying them from means-tested provincial benefits. Its defining feature is that the trustee has absolute discretion over whether and when to distribute funds — the beneficiary has no automatic right to demand the money. Because the beneficiary can’t compel a distribution, the trust assets are generally not treated as the beneficiary’s own for benefit-eligibility purposes, which lets the trust supplement their quality of life without displacing benefits. Funds can be used at the trustee’s discretion for things beyond what basic benefits cover. It takes its name from a Canadian legal case; the concept is well established, but treatment isn’t uniform nationwide — some provinces accommodate it more clearly than others, and the specific rules matter. Setting one up correctly is essential, since an improperly drafted trust may not achieve the protection. Always establish a Henson trust with a lawyer experienced in this area. General information, not legal advice.

What is an RDSP and how does it help?
The Registered Disability Savings Plan is a federal registered plan to help build long-term security for a person who qualifies for the Disability Tax Credit. Contributions grow tax-deferred, and the plan can attract federal government grants and, for lower-income situations, bonds — making it a powerful long-term savings tool. In most provinces, RDSP assets and withdrawals are treated favourably and generally don’t reduce provincial disability benefits, though the exact treatment can vary and should be confirmed provincially. In estate planning, the RDSP is often used alongside a Henson trust rather than instead of it: the RDSP for long-term, government-supported savings; the trust for flexibility, a wider range of assets, and larger amounts. There are rules on contributions, the grants and bonds, and withdrawals, including provisions if funds come out early. Because coordinating an RDSP with a trust and overall plan is technical, work with professionals who understand both the RDSP and provincial benefit rules. General information, not financial advice.

How should I leave money to a family member with a disability?
There’s no single right answer — it depends on the person’s situation, province, benefits, and the family’s circumstances — but the essential principle is clear: money for a family member with a disability generally should not be left to them outright if they rely on means-tested benefits, because it can jeopardize those benefits. Instead, families use purpose-built tools. A properly structured trust, often a Henson trust with the trustee holding absolute discretion, can hold the inheritance and enhance the person’s life without counting as their asset. An RDSP can provide long-term, government-supported savings. These are often used together, with careful choice of a trustee to manage it well over many years. Life insurance is sometimes used to fund such a trust. The right combination depends on the individual circumstances and provincial rules, which vary and are technical. Because getting this right protects both the inheritance and ongoing benefits, always plan with a lawyer experienced in planning for beneficiaries with disabilities, coordinated with financial and tax advice.
