RDSP in Canada: The Complete Guide to the Registered Disability Savings Plan

The Registered Disability Savings Plan offers the most generous government grant matching of any registered account in Canada. For a low-income family, the government can deposit more than three dollars for every dollar contributed. For any eligible family, the RDSP typically delivers far more value than any other registered account per dollar invested.

Yet it remains the least-known major registered account. Families who could be receiving thousands of dollars in government grants each year go without because the account was never mentioned to them.

This post is part of a series on Canada’s registered accounts. See also: RRSP and RRIF, TFSA, FHSA, RESP.

Who Qualifies?

To open an RDSP, the beneficiary must:

• Be eligible for the Disability Tax Credit (DTC). This requires a qualified medical practitioner to certify that the individual has a severe and prolonged physical or mental impairment. The DTC application is submitted to CRA on Form T2201.
• Be a Canadian resident
• Have a valid Social Insurance Number
• Be under age 60 (contributions and government grants are not available after age 59)

The DTC application is the starting point. If a family member has a disability but has not applied for the DTC, that is the first step before anything else. Approval can take several months, but the DTC can sometimes be applied retroactively.

The holder (the person who opens and controls the RDSP) can be the beneficiary themselves, a legal parent of a minor beneficiary, or a legal guardian. Once the beneficiary reaches the age of majority in their province and is legally capable, they can become the plan holder themselves.

Contribution Limits

There is no annual contribution limit. The lifetime maximum is $200,000 per beneficiary. Contributions can be made by the beneficiary, their family, or anyone with written permission from the plan holder.

Contributions are made with after-tax dollars and are not deductible. Investment growth inside the RDSP is tax-sheltered until withdrawal.

Canada Disability Savings Grant (CDSG)

The CDSG is a government matching grant deposited directly into the RDSP. The matching rate depends on the beneficiary’s adjusted family net income, which is based on the family income reported on tax returns two years prior (for 2026 RDSP transactions, the income from 2024 tax returns applies).

Source: Employment and Social Development Canada, 2026 RDSP grant rates. The $114,750 threshold is the 2025 indexed amount applied to 2026 transactions. Verify the current threshold directly with ESDC before acting, as it is adjusted annually.

The lifetime CDSG limit is $70,000. Grant room accumulates from age 0 (or from the year the DTC is first approved) but can only be paid until the end of the calendar year the beneficiary turns 49.

Catch-up grants: unused grant room from prior years can be accessed, but only two years of unused room can be accessed per calendar year. If you open an RDSP late for a child who has been DTC-eligible since birth, the catch-up process can still deliver significant grants, though not all missed years can be recovered.

Canada Disability Savings Bond (CDSB)

The CDSB is a government deposit that requires no contributions. It is available to lower-income beneficiaries:

• Up to $1,000 per year
• Lifetime maximum: $20,000
• No contributions required to receive the bond
• Income-tested based on the beneficiary’s (or their family’s) net income

The CDSB is available until the end of the calendar year the beneficiary turns 49. Like the CDSG, unused bond room can be accessed retroactively (two years at a time).

For a low-income family that simply opens an RDSP and does nothing else, the government can deposit up to $20,000 in bond payments over the beneficiary’s eligible years. This is the RDSP equivalent of the RESP’s Canada Learning Bond: free government money that requires no family contribution.

The 10-Year Holdback Rule

This is the most important and least understood rule of the RDSP. When you make a withdrawal from an RDSP, you may be required to repay a portion of the government grants and bonds received in the prior 10 years.

Specifically: for every dollar withdrawn, $3 of grants and bonds received in the last 10 years must be repaid (up to the total amount of grants and bonds received in that period). This is why the RDSP is designed for long-term savings, not short-term access.

Example: if the RDSP received $10,000 in CDSG over the past 10 years and you withdraw $5,000, you must repay $15,000 in government money (3 times the withdrawal) or the total $10,000 in grants received in the 10-year window, whichever is less.

Safe harbour: withdrawals of up to $10,000 per year are available under the Lifetime Disability Assistance Payment schedule without triggering the holdback, provided the RDSP has been open long enough and specific conditions are met.

The practical implication: do not open an RDSP expecting to withdraw in the short term. Plan for long-term savings of at least 10 years to maximize grants without repayment obligations.

Lifetime Disability Assistance Payments (LDAPs)

After the plan has been in place for a sufficient period, the beneficiary can begin receiving regular withdrawals called Lifetime Disability Assistance Payments. LDAPs must begin by December 31 of the year the beneficiary turns 60.

There is a formula that caps the annual withdrawal amount. LDAP withdrawals are included in the beneficiary’s taxable income in the year received. Since many beneficiaries have low income, the effective tax rate is often minimal.

What Happens if DTC Eligibility Ends?

If the beneficiary loses DTC eligibility, no new contributions or government grants can be made. However, a 5-year grace period applies: if the beneficiary’s DTC eligibility is expected to be reinstated within that time, the plan can remain open.

If eligibility is not reinstated and the plan is closed within 10 years of receiving government assistance, the holdback rule applies to any withdrawals. The plan can remain open and continue to grow tax-free even without new contributions.

RRSP Rollovers to an RDSP

When a parent or grandparent who holds an RRSP or RRIFdies, they can roll over up to $200,000 from their RRSP or RRIF directly into the RDSP of a financially dependent child or grandchild with a disability, without triggering tax on the rollover. The rollover uses the beneficiary’s RDSP contribution room.

This is a meaningful estate planning tool for families with a disabled beneficiary. It allows tax-sheltered wealth to transfer across generations without the usual income inclusion that applies to RRSP/RRIF transfers.

Investing Inside an RDSP

The eligible investments in an RDSP are the same as an RRSP and TFSA: stocks, ETFs, bonds, GICs, mutual funds, and cash. Given the long time horizon typical of an RDSP, a diversified, growth-oriented portfolio is appropriate for most beneficiaries.

Newcomers to Canada

The RDSP is available to newcomers who meet the eligibility requirements: Canadian residency, valid SIN, and DTC eligibility. Families who recently arrived with a family member who has a disability should apply for the DTC as soon as possible after establishing residency. The RDSP cannot be opened until the DTC is approved, but grant catch-up is possible for prior years of DTC eligibility.

Opening an RDSP

RDSPs are offered by most major Canadian banks and some credit unions and investment dealers. The process involves completing the plan holder and beneficiary documentation and submitting the DTC approval confirmation. Once open, government grants and bonds are paid automatically based on the annual contribution and family income.
