Key takeaways
  • ODSP does not count a true absolute discretionary (Henson) trust as an asset, no matter how much capital it holds.
  • Other trusts, and payments from them, face dollar limits under ODSP, so the exact wording of the trust matters.
  • An RDSP has its own separate rules, so compare it with a trust using advice that looks at your whole family situation.

If you are planning for a relative with a disability, you may hear about two tools: a Registered Disability Savings Plan (RDSP) and a discretionary trust, often called a Henson trust. Families often ask which one is better, and the honest answer is that it depends on the person's benefits, the size of the gift and the family's goals.

This article explains how Ontario's disability support program (ODSP) treats trust money, since that is where a discretionary trust matters most. It does not set out the rules for RDSPs, which are separate and worth confirming with a lawyer or accountant before you decide.

Two tools with different rules

A discretionary trust is a legal arrangement in which a trustee holds money for a beneficiary and decides when and how much to pay. An RDSP is a different kind of savings arrangement with its own eligibility, contribution and withdrawal rules. They are not interchangeable, and some families use both.

Because the two work differently, it is not helpful to ask which is best in the abstract. A better approach is to ask how each one affects the person's ODSP, who controls the money, and what happens to any balance later.

How ODSP treats a Henson trust

Under ODSP rules, a true absolute discretionary (Henson) trust is not counted as an asset, no matter how much capital it holds.

A payment from that kind of trust is treated as a voluntary payment, because the trustee decides whether to pay and has no obligation to do so.

ODSP reviews each trust's terms individually, so a trust only gets this treatment if it is truly discretionary. Wording that gives the beneficiary a right to the money can change the result.

Trusts that are not fully discretionary

A recipient's beneficial interest in a non-discretionary trust whose capital comes from an inheritance or life insurance proceeds, and is available for maintenance, is exempt only up to a combined $100,000, together with the cash surrender value of life insurance.

If a recipient receives an inheritance or life insurance money directly, they may be given up to six months to put it into a trust, provided the trust is set up as soon as possible. Otherwise the money is treated as income in the month it is received.

Members of an ODSP benefit unit cannot put their own money, or money they are entitled to, into a private trust and have it exempted.

Payments out of a trust

Even when the trust itself is not counted, payments to the recipient may count as income. The treatment depends on what the money is used for.

Type of paymentODSP treatment
Used for disability-related items or services approved by the Director, or approved disability-related education or trainingFully exempt
Other trust, life insurance, gift or voluntary paymentsExempt only up to $10,000 in any 12-month period; amounts above that count as income in the month received

The $10,000 limit is one to confirm against the current regulation with a lawyer, since ODSP rules can change.

What to do next

A trustee of a discretionary trust also has duties. In investing trust property, a trustee must use the care, skill, diligence and judgment of a prudent investor. The trust's own terms still govern, and the Trustee Act's investment powers do not authorize a trustee to act inconsistently with them.

Frequently asked questions

Is a Henson trust counted as an asset for ODSP?

A true absolute discretionary (Henson) trust is not counted as an asset under ODSP rules, no matter how much capital it holds. ODSP reviews each trust's terms individually, so the wording matters.

Do payments from a Henson trust affect ODSP?

A payment from an absolute discretionary trust is treated as a voluntary payment. Payments used for approved disability-related items or services are fully exempt, while other payments are exempt only up to $10,000 in any 12-month period.

Can the person with a disability put their own money in a trust?

Members of an ODSP benefit unit cannot put their own money, or money they are entitled to, into a private trust and have it exempted. A lawyer can explain what options exist for other sources of funds.

Should we choose an RDSP or a trust?

It depends on the person's benefits, the amount involved and who should control the money. Some families use both, so it is worth asking a lawyer or accountant to look at the whole picture.
