What Is an RDSP? Canada's Disability Savings Plan Explained

Most Canadians have never heard of the Registered Disability Savings Plan, and that's a real problem — it's one of the few accounts in the entire tax system where the government routinely contributes more money than the account holder does. It was created in 2008 specifically to help people with disabilities and their families build long-term financial security, yet a large share of eligible Canadians still aren't using it, often simply because no one ever told them it existed.

This guide explains what an RDSP is, who qualifies, how the government matching actually works, and the rules worth knowing before opening one.

What is an RDSP?

A Registered Disability Savings Plan (RDSP) is a registered account that helps a person with a severe and prolonged disability save for the future. If the

RESP is familiar, the RDSP works on a similar principle for disability savings instead of education: contributions grow tax-deferred inside the account, and — its biggest advantage — the government can add grant and bond money directly on top of what's contributed.

The account belongs to one person, called the beneficiary. Money inside it can eventually be used for anything — there's no restriction that it has to go toward a specific expense like education or a home.

Who is eligible for an RDSP?

To open an RDSP, the beneficiary generally needs to meet all of the following:

• Be a resident of Canada
• Have a valid Social Insurance Number (SIN)
• Be under age 60 when the plan is opened
• Be approved for the Disability Tax Credit (DTC)

There's no income requirement to open an RDSP — income only affects how much grant and bond money the account can receive each year, not whether someone qualifies for the account itself.

The Disability Tax Credit (DTC) requirement

Approval for the

Disability Tax Credit (DTC) is the gate that everything else depends on — an RDSP cannot be opened without it. The DTC is a separate federal tax credit for Canadians with a severe and prolonged impairment in physical or mental functions, applied for using CRA Form T2201, which a medical practitioner certifies and the CRA then reviews.

A few things worth knowing:

• The DTC covers a wide range of severe and prolonged impairments — physical and mental — not only conditions that are visible or permanent.
• Approval can sometimes be applied retroactively to past tax years, which can also unlock retroactive RDSP grant and bond room.
• A denied application isn't necessarily final. Applications can be reassessed or resubmitted with more complete medical information.

If DTC status is ever lost, an RDSP doesn't always have to close immediately — specific continuity rules can apply for a limited period. That situation is specific enough that it's worth confirming directly with the RDSP issuer or the CRA rather than assuming either outcome.

How RDSP contributions work

Anyone can contribute to an RDSP with the written permission of the plan holder — it doesn't have to be the beneficiary themselves. A parent, grandparent, other family member, or friend can all contribute.

Contributions aren't tax-deductible, unlike an RRSP. What you get instead is the possibility of government grant and bond money, plus tax-deferred growth inside the account until money is withdrawn.

The Canada Disability Savings Grant (CDSG)

The

Canada Disability Savings Grant (CDSG) matches personal contributions, and the matching rate depends on the beneficiary's family net income:

The lifetime CDSG maximum is $70,000 per beneficiary. Income thresholds are indexed annually, so the exact dollar figure shifts slightly most years — this is the current figure, but it's worth confirming the latest number directly with the CRA or ESDC before making contribution decisions.

The Canada Disability Savings Bond (CDSB)

The

Canada Disability Savings Bond (CDSB) is money the government deposits directly into an RDSP for lower-income beneficiaries — no personal contribution is required to receive it.

The lifetime CDSB maximum is $20,000 per beneficiary. A beneficiary can receive both the CDSG and the CDSB in the same year — they aren't mutually exclusive.

Contribution limits

There's no annual contribution limit for an RDSP, but there is a lifetime one: $200,000 per beneficiary, across all contributions ever made. Contributions can be made until the end of the year the beneficiary turns 59.

Grant and bond eligibility ends earlier than the contribution deadline — the CDSG and CDSB are only paid for contribution years up to and including the year the beneficiary turns 49. Contributing after that age still grows the account tax-deferred, but no further government matching is added.

Government matching, explained with examples

The matching structure is easiest to understand with real numbers.

Example: a lower-income family

Example: a higher-income family

Both examples assume a single contribution year — actual totals depend on contributions and income in every year the RDSP is open, not just one.

Who can open an RDSP?

Who can act as the plan holder depends on the beneficiary's age and legal capacity:

• An adult beneficiary who is contractually competent can open and manage their own RDSP.
• A minor beneficiary has the plan opened by a parent or legal guardian.
• An adult beneficiary whose contractual competence is in doubt, with a legal guardian or representative already in place, has that representative open the plan.
• An adult beneficiary whose contractual competence is in doubt, with no legal representative in place, may currently have a "qualifying family member" — a parent, sibling, or spouse/common-law partner — open the plan instead, under a temporary federal measure. As of this writing, that measure is set to apply to plans opened before the end of 2026; confirm its current status before relying on it.

How withdrawals work

RDSP withdrawals come in two forms:

• Disability Assistance Payments (DAPs) — one-time or occasional withdrawals, made on request.
• Lifetime Disability Assistance Payments (LDAPs) — recurring annual withdrawals (covered in more detail below).

When money comes out, the original contributions (already after-tax money) come out tax-free. The portion made up of grant money, bond money, and investment growth is taxed as income to the beneficiary in the year it's withdrawn.

Lifetime Disability Assistance Payments (LDAP)

An LDAP is a recurring, formula-based annual payment. It can start earlier if needed, but it must begin by the end of the year the beneficiary turns 60. Once LDAPs begin, they continue every year for as long as the account holds money, or until the beneficiary dies.

Important rules and restrictions

A few rules catch people off guard more than any others:

• The proportional repayment rule (the "10-year rule"). If grant or bond money was paid into the RDSP within the last 10 years, withdrawing can trigger repayment of $3 of grant/bond money for every $1 withdrawn, up to the total grant and bond money received in that 10-year window (known as the Assistance Holdback Amount). This rule stops applying once the beneficiary turns 60.
• Only one RDSP can exist per beneficiary at a time — unlike a TFSA or RRSP, where holding accounts at multiple institutions is normal.
• Unused grant and bond entitlement from previous years can sometimes be claimed retroactively, back to 2008, once DTC-approved — it isn't automatic, so it's worth asking about specifically.
• Contributions stop being accepted after the year the beneficiary turns 59, and grant/bond matching stops even earlier, after the year the beneficiary turns 49.

RDSP vs. TFSA vs. RRSP

All three are registered accounts, but they solve different problems. This is an educational comparison, not a recommendation to prioritize one over another — that depends entirely on individual circumstances.

For a full breakdown of the TFSA and RRSP specifically, see the TFSA vs. RRSP guide.

Common mistakes people make with RDSPs

• Waiting to apply for the DTC "until it feels necessary." Grant and bond eligibility ends after the year the beneficiary turns 49 — that clock doesn't pause for anyone.
• Not contributing because "we can't afford much." Even a small contribution can unlock a large CDSG match in a lower-income year — it's the percentage that matters, not the size of the contribution.
• Assuming only the beneficiary can contribute. Family and friends can contribute too, with the plan holder's permission.
• Withdrawing without checking the 10-year repayment rule first, and losing grant or bond money unexpectedly as a result.
• Never checking for unused grant and bond room from past years. It isn't applied automatically — it has to be asked about.

What to do next

If a Disability Tax Credit approval is already in place, or looks likely, opening an RDSP — even with a small first contribution — is usually worth doing sooner rather than later, simply because grant and bond eligibility has a hard age cutoff that doesn't wait for the "right" time.
