The intersection of disability benefits and investing is poorly documented. Most resources explain either the Disability Tax Credit or the RDSP in isolation, without explaining how they interact — or how other accounts like the TFSA and RRSP fit into the picture for someone with a disability. This page covers the full picture.
The stakes are high: failing to open an RDSP early can cost tens of thousands in unclaimed government contributions. And misunderstanding how investment income interacts with provincial disability benefits like ODSP can create unexpected clawbacks.
Disability Tax Credit (DTC) Eligibility
The DTC is a non-refundable federal tax credit for Canadians with a severe and prolonged impairment in physical or mental functions. "Severe" means the impairment markedly restricts the person in one or more basic activities of daily living. "Prolonged" means the impairment has lasted or is expected to last at least 12 consecutive months.
To apply, you need to complete Form T2201 (Disability Tax Certificate). Your medical practitioner (doctor, nurse practitioner, psychologist, audiologist, optometrist, physiotherapist, or occupational therapist, depending on the type of disability) must certify the details. Submit the T2201 to the CRA — approval is not automatic and can take 6–12 weeks.
CRA can approve DTC retroactively for past years, allowing you to amend prior returns and claim the Disability Amount tax credit on line 31600 going back up to 10 years. If your disability has existed for years but you never applied, this retroactive claim can result in a significant tax refund.
The DTC is the gateway: You cannot open an RDSP without first having DTC approval from the CRA. If your DTC is denied, you can appeal — the Disability Tax Credit Coalition provides free guidance on navigating the appeals process.
Once approved, the DTC also provides the non-refundable Disability Amount credit (roughly $9,428 federally in 2025), reducing your tax payable by about $1,414 per year at the 15% federal rate.
RDSP Basics
The Registered Disability Savings Plan (RDSP) is a federal program designed to help Canadians with disabilities save for long-term financial security. The key features that make it uniquely valuable are the government matching contributions — grants and bonds — that go into the account alongside your own contributions.
Canada Disability Savings Grant (CDSG)
The government matches private RDSP contributions based on family income:
- For families with net income ≤ $106,717 (2025): 300% match on first $500 contributed (up to $1,500), plus 200% match on next $1,000 contributed (up to $2,000) = maximum $3,500/year grant
- For families with net income above $106,717: 100% match on first $1,000 contributed = maximum $1,000/year grant
- Lifetime maximum CDSG: $70,000
If you open an RDSP late, unused grant room from prior years carries forward. The CRA will pay out up to 10 years of missed grants retroactively if you qualify. For someone who qualifies for DTC at age 30 and opens an RDSP immediately, this could mean accessing the maximum grant for multiple past years in a lump sum.
Canada Disability Savings Bond (CDSB)
The CDSB provides up to $1,000/year to RDSP holders with low family income — no contribution required to receive it. At a net family income of $33,015 or less (2025), the full $1,000 bond applies. At income between $33,015 and $50,197, a partial bond is paid. Above $50,197, no bond is paid.
Lifetime maximum CDSB is $20,000. Like the grant, missed bond years can accumulate and be claimed retroactively.
Contribution Limits and the 10-Year Rule
Lifetime RDSP contributions are capped at $200,000 (though there's no annual contribution limit). There's no contribution room based on income — anyone with DTC approval can contribute up to $200,000 lifetime, subject to the matching grant structure.
The 10-year rule is critical: if the RDSP received government grants or bonds within the past 10 years, any withdrawal requires repaying $3 of grants/bonds for every $1 withdrawn. This is called the "Assistance Holdback Amount" (AHA). Practically, this means the RDSP is a long-term savings vehicle — you should not plan to access it within 10 years of your last grant or bond deposit.
The DTC-RDSP Connection
You need active DTC status to maintain your RDSP. If CRA revokes your DTC (because your condition has improved or a re-certification determines you no longer qualify), you must close your RDSP within a specified period — typically the end of the following calendar year.
Closing the RDSP triggers repayment of all government grants and bonds received within the past 10 years, plus any investment growth attributable to those amounts. This is a significant risk for people with episodic disabilities or conditions that may be viewed as "resolved" by CRA reviewers.
If your disability is permanent and lifelong, DTC revocation risk is low. If your condition is fluctuating or you're near the borderline of DTC criteria, discuss this risk with a financial planner before aggressively funding an RDSP.
RDSP at Big Banks vs Questrade
This is where most RDSP holders leave money on the table. Big bank RDSPs — at TD, RBC, BMO, Scotiabank, CIBC — restrict you to their proprietary mutual funds, which often carry MERs of 1.8–2.5%. On a $100,000 RDSP, that's $1,800–2,500 per year in fees eating your government-matched returns.
Questrade offers the best self-directed RDSP in Canada. You can hold ETFs with MERs of 0.06–0.25%, buy individual stocks, and manage the account yourself. Questrade's RDSP supports all standard investments eligible for registered accounts. No annual account fees for RDSPs (as of 2025 — confirm current terms before opening).
The tradeoff is complexity. A self-directed RDSP requires you to manage your own investments and understand contribution/grant mechanics. For someone comfortable with basic investing, the fee savings over 20–30 years are enormous. For someone who isn't, a low-cost robo-advisor (Wealthsimple does not currently offer RDSPs as of 2025 — verify) or big bank with a simple balanced fund may be more appropriate.
| Provider | Investment options | Typical MER | Self-directed? |
|---|---|---|---|
| Big 5 Banks (TD, RBC, etc.) | Proprietary mutual funds | 1.8–2.5% | No |
| Questrade | ETFs, stocks, bonds, GICs | 0.06–0.25% (ETFs) | Yes |
| Credit unions (some) | GICs, limited mutual funds | Varies | Partial |

Henson Trusts: When an RDSP Isn't the Right Vehicle
For individuals who cannot manage their own finances or whose disability prevents independent decision-making, an RDSP still requires a legal representative (parent or guardian as plan holder for adults who lack capacity). An alternative — or complement — is a Henson Trust.
A Henson Trust is a discretionary trust, typically set up by a will, that holds assets for a beneficiary with a disability. The key feature is that the beneficiary has no right to demand assets — distributions are entirely at the trustee's discretion. This structure exempts the trust assets from being counted as the beneficiary's assets for provincial disability benefit eligibility purposes (ODSP in Ontario, for example).
Henson trusts require a lawyer to set up properly and are typically funded through an estate (inheritance). They're most relevant when a parent wants to leave money to a child with a disability without disqualifying them from provincial support programs. The Plan Institute and community legal aid organizations across Canada provide guidance on Henson trust structures.
RDSP at Death: Government Clawback
When an RDSP holder dies, the plan must be closed. All grants and bonds received within the prior 10 years must be repaid to the government (the Assistance Holdback Amount). Remaining funds — contributions plus growth minus AHA repayment — go to the estate.
If someone opened an RDSP at age 60 with a terminal diagnosis and loaded in $50,000 of contributions to access $3,500 in matching grants, and died 18 months later, only 18 months of grants would need repayment (under 10 years of grants received). The $50,000 in contributions and investment growth passes to the estate.
Planning around the 10-year horizon matters. If someone with a shortened life expectancy opens an RDSP, the grants received in the last 10 years of life will be clawed back. Contributions are always retained by the estate.
DTC and Your TFSA/RRSP
The DTC does not directly affect TFSA or RRSP eligibility or contribution limits. Any Canadian with earned income can contribute to an RRSP (contribution room based on income), and any Canadian over 18 can contribute to a TFSA — disability status is irrelevant.
Where the DTC helps with these accounts is indirectly: the Disability Amount (line 31600) reduces your net income for tax purposes, lowering your marginal rate. This means RRSP withdrawals cost less in tax, and the value of TFSA tax sheltering may be relatively lower for someone with very low income who pays minimal tax regardless.
For people receiving the CDSB (low income), their marginal tax rate may already be near zero — in which case RRSP contributions generate minimal tax benefit, and TFSA or direct RDSP contributions are typically more valuable.
Ontario ODSP: Investment Income Rules
The Ontario Disability Support Program (ODSP) has specific rules about how investment income is treated — and they differ significantly from earned income rules.
Earned income has an exemption of $1,000/month before clawback (as of 2024 — verify current exemption amounts with ODSP). Investment income does not get this same earned income exemption. However, ODSP exempts income held in registered accounts (TFSA, RRSP, RDSP) from asset and income calculations entirely. This makes registered accounts particularly valuable for ODSP recipients — money invested inside a TFSA doesn't count against ODSP asset limits, and growth within registered accounts is invisible to ODSP calculations.
Non-registered investment income (dividends, interest, capital gains from a taxable account) is treated as unearned income for ODSP purposes and can reduce benefits dollar-for-dollar above applicable exemptions. ODSP recipients should prioritize maximizing TFSA and RDSP contributions before building a non-registered investment account.
Priority order for ODSP recipients investing:
1. Max RDSP to capture all available CDSG and CDSB government contributions
2. Max TFSA — exempt from ODSP asset limits, tax-free growth
3. RRSP only if you have earned income and meaningful tax to offset
4. Non-registered last — income from this account can affect ODSP benefits
