The RDSP Explained: The Registered Disability Savings Plan
How the Registered Disability Savings Plan works in Canada, including eligibility, government grants and bonds, and the rules around withdrawals.
The Registered Disability Savings Plan, or RDSP, is one of the most generous accounts in the Canadian tax system, yet it remains underused. It is a tax-sheltered plan for people approved for the Disability Tax Credit. Contributions are not deductible, but they attract substantial government grants, and for lower-income families the government adds bonds that require no contribution at all. Growth is tax-deferred, and the plan is designed to provide long-term financial security for a person with a disability.
This guide explains who qualifies, how the grants and bonds work, and the withdrawal rules that make the RDSP distinctive. It is written for people with disabilities and the families who support them in Ottawa and across Ontario. Treat it as general education and confirm specifics, since the rules have detail.
What the RDSP is
An RDSP is a long-term savings account with a single purpose: to build financial security for a person with a disability. The account belongs to the beneficiary, and contributions can be made by the beneficiary, family members, or others with the holder’s permission. Inside the plan, investments grow tax-deferred, and the real power comes from the government money layered on top.
Two features set the RDSP apart from other registered accounts. First, the generosity of the grants and bonds, which can add far more than the account holder contributes. Second, the way it is treated by provincial benefit programs, which in most provinces leave RDSP assets and income untouched. Together these make the RDSP a cornerstone of planning for a family member with a disability, a topic that also touches Henson trusts for broader estate protection.
Who qualifies
Eligibility rests on the Disability Tax Credit. To be an RDSP beneficiary you generally must:
- Be a resident of Canada with a valid Social Insurance Number.
- Be under a certain age when the plan is opened and when contributions are made.
- Be approved for the Disability Tax Credit.
Because the Disability Tax Credit is the gateway, securing that approval is the essential first step. The application requires certification from a medical practitioner, and approval also opens the door to other tax benefits. If the beneficiary is an adult with the capacity to manage their affairs, they open the plan themselves; otherwise a qualifying family member or guardian can act as the holder.
The Canada Disability Savings Grant
The Canada Disability Savings Grant matches contributions, and the match can be strikingly generous for lower and middle-income families. Depending on family income, the first portion of annual contributions can be matched at a higher rate, with additional contributions matched at a lower rate, up to an annual and a lifetime maximum.
The structure rewards even modest contributions, because the highest match applies to the first dollars contributed each year. For a family of limited means, a small annual contribution can draw a multiple of itself in grant money. The grant is available up to the end of the year the beneficiary turns 49, so there is a long window, and unused grant entitlement can often be carried forward and claimed with catch-up contributions.
The Canada Disability Savings Bond
The bond is even more remarkable, because it requires no contribution at all. For lower-income families, the government deposits the bond into the RDSP each year simply for having the plan open and applying, up to an annual and a lifetime maximum. Like the grant, unused bond entitlement can generally be carried forward.
This means a lower-income family that cannot afford to contribute should still open an RDSP, because the bond is free money that accumulates year after year. It is one of the clearest examples in Canadian finance of a benefit left unclaimed purely because people do not know it exists.
| Government addition | Requires contribution | Based on family income | Rewards |
|---|---|---|---|
| Canada Disability Savings Grant | Yes | Yes, higher match at lower income | Matches contributions to a lifetime cap |
| Canada Disability Savings Bond | No | Yes, for lower incomes | Deposited regardless of contribution |
The ten-year holdback rule
The RDSP’s generosity comes with a condition designed to keep it focused on the long term. Government grants and bonds paid into the plan are subject to a ten-year holdback. If you withdraw from the RDSP, a portion of the grants and bonds received in the previous ten years must generally be repaid to the government.
The practical implication is that the RDSP is not a short-term savings vehicle. Withdrawing soon after receiving grants and bonds can trigger significant repayment, eroding the benefit. The plan works best when contributions and government money are left to compound for many years before withdrawals begin, which is why it should be integrated into a long-term plan rather than treated as an emergency fund.
How withdrawals work
Withdrawals from an RDSP are structured to provide income over the beneficiary’s lifetime. There are two broad forms: regular, scheduled payments that must begin by a certain age and continue for life, and occasional lump-sum withdrawals, both subject to the holdback rule. When money comes out, the portion representing contributions is not taxed, while the portion representing grants, bonds, and growth is taxable to the beneficiary, who often has little other income and therefore pays little or no tax.
Because the beneficiary’s taxable income is frequently low, the tax on withdrawals is usually modest, which adds to the plan’s appeal. The timing and form of withdrawals should be planned around the holdback and the beneficiary’s needs.
Protection of provincial benefits
In most provinces, including Ontario, RDSP assets and the income drawn from the plan are exempt from the asset and income tests used for provincial disability support such as the Ontario Disability Support Program. This is one of the RDSP’s most valuable features: it allows a person with a disability to build real savings without losing the benefits they rely on. Treatment can vary and rules change, so confirm the current position in your province before relying on it.
Coordinating the RDSP with your estate plan
For many families, the RDSP is one piece of a larger question: how to provide for a family member with a disability over the long term, including after the parents are gone. The RDSP builds savings in the beneficiary’s own name, which is powerful, but it does not by itself answer what happens to an inheritance or to ongoing support once parents can no longer provide it.
This is where the RDSP works alongside other tools. A Henson trust, for example, can hold assets for a person with a disability without those assets being counted against provincial benefits, complementing the RDSP’s own benefit protection. Thoughtful beneficiary designations and a well-drafted will ensure that money intended for the beneficiary reaches them in a way that preserves both their benefits and the RDSP’s advantages. Rolling certain registered assets of a deceased parent into a child’s RDSP may also be possible in some circumstances, subject to conditions and limits.
The practical message is that the RDSP should not sit in isolation. It is most effective when it is coordinated with trusts, insurance, and the estate plan, so that the generous grants and bonds are protected and the family member is provided for across their whole life.
Next step
The RDSP combines generous grants, a no-contribution bond, tax-deferred growth, and protection of provincial benefits, yet many eligible families never open one. Securing the Disability Tax Credit and structuring contributions to capture the full grant and bond can transform a family member’s long-term security.

Frequently asked questions
Who can open and benefit from an RDSP?
The beneficiary must be a Canadian resident under a certain age with a valid Social Insurance Number who is approved for the Disability Tax Credit. The plan is opened by the beneficiary if they are an adult with capacity, or by a qualifying family member or guardian otherwise. Eligibility hinges on the Disability Tax Credit, so securing that approval is the first step.
What is the grant and bond holdback rule?
Government grants and bonds paid into the RDSP are subject to a ten-year holdback. If you withdraw from the plan, a portion of the grants and bonds received in the previous ten years must generally be repaid to the government. This rule is designed to keep the plan focused on long-term savings, so withdrawals need to be planned carefully.
Will an RDSP affect provincial disability benefits?
In most provinces, including Ontario, RDSP assets and the income drawn from the plan are exempt and do not reduce provincial disability support such as ODSP. This is one of the RDSP's most valuable features, since it lets a person build meaningful savings without jeopardising their benefits. Confirm the current rules in your province, as treatment can vary.
