Who Can Open an RDSP and What Role Does the Disability Tax Credit Play?

Fewer than a third of Canadians who qualify for a Registered Disability Savings Plan (RDSP) actually have one open. That’s not a guess. A Statistics Canada survey on savings for persons with disabilities put the figure at about 31.5% as of 2020, and the gap isn’t mainly about people deciding the plan isn’t worth it. It’s that most eligible families never get past the first gate, because RDSP eligibility isn’t really its own separate test. It’s a downstream consequence of a completely different, and much stricter, approval process.

An RDSP is open to anyone who has been approved for the Disability Tax Credit (DTC), has a valid Social Insurance Number, is a Canadian resident, and is under 60 years old when the plan is opened. Approval for the DTC is the real hurdle, since it requires a medical practitioner to certify a severe and prolonged impairment using the Canada Revenue Agency’s (CRA) specific functional criteria, not a diagnosis on its own.

What Actually Makes Someone Eligible

The Canada Revenue Agency’s own eligibility page lays out four conditions a beneficiary has to meet, and all four have to hold at once. The person needs to be approved for the DTC, unless they’re receiving a transfer from an existing RDSP into a new one. They need a valid SIN. They need to be a Canadian resident at the time the plan is entered into. And they need to be under age 60, since a plan can be opened for someone right up until the end of the year they turn 59.

None of those four conditions individually trip people up as often as the first one does. A family can meet the SIN, residency, and age requirements without a second thought and still spend months stuck because nobody in the household has gone through the DTC application yet, which is a different starting point than most people expect after reading about what an RDSP actually is.

The Disability Tax Credit Is the Real Gatekeeper

Here’s the part that surprises a lot of people going through this for the first time. The DTC isn’t assessed based on your diagnosis. It’s assessed based on how your impairment affects your ability to function day to day, certified in detail by a doctor or another qualified practitioner on Form T2201.

To qualify, the impairment has to be severe and prolonged, meaning it has lasted or is expected to last at least 12 continuous months, and it has to fall into one of several specific categories. Under the CRA’s technical guidance on the credit, a person qualifies if they’re markedly restricted in a basic activity of daily living (walking, feeding or dressing oneself, hearing, speaking, eliminating bowel or bladder function, or performing the mental functions needed for everyday life), if they’re significantly restricted in more than one of those activities and the cumulative effect equals a marked restriction in just one, or if they’d be markedly restricted without extensive life-sustaining therapy taken at least twice a week for an average of 14 hours weekly. Being legally blind qualifies on its own.

Two people with the identical medical diagnosis can get different answers from the CRA, because the form asks the practitioner to describe functional limitation, not name a condition. That’s the piece most people don’t expect walking in, and it’s why a DTC denial doesn’t necessarily mean the underlying condition wasn’t serious. It sometimes just means the form didn’t capture the functional impact clearly enough.

Who Can Actually Open the Account

Being an eligible beneficiary and being the person who opens and controls the account (called the plan holder) aren’t the same thing, and this step determines who’s even allowed to sign the paperwork before anything about how an RDSP compares to other registered accounts becomes relevant. This is where families with adult children or aging parents run into a second layer of complexity. An adult beneficiary who’s contractually competent opens and holds their own plan. A minor’s plan is opened by their legal parent or another legal representative. And an adult whose ability to enter into a contract is in doubt, without a legal guardian already in place, needs someone else to step in.

That last group has a real, time-limited option worth knowing about. A temporary federal measure allows a “qualifying family member,” meaning a spouse, common-law partner, parent, or sibling of the beneficiary, to open and hold the RDSP on that person’s behalf without going through the provincial guardianship process. This was first introduced in 2012 and has been extended twice since, and the current version runs only until December 31, 2026. Once that measure ends, families in the same situation may need to pursue formal legal representation through their province instead, which is a slower and more expensive process. If this describes your family’s situation, opening the plan before the deadline rather than after it is worth the added urgency.

The Age Rule Nobody Reads Closely

Contributions to an RDSP can be made until the end of the year the beneficiary turns 59. Most people assume the government’s matching incentives follow the same timeline. They don’t.

Both the Canada Disability Savings Grant (CDSG) and the Canada Disability Savings Bond (CDSB) stop being payable after December 31 of the year the beneficiary turns 49, a full decade before the contribution cutoff. A family that waits until a beneficiary is in their early 50s to open an RDSP can still contribute and get tax-deferred growth, but they’ve already missed the entire window for free government money, which is often the biggest financial reason to open the plan in the first place. Canada.ca’s own explanation of grant and bond amounts states this cutoff plainly, and it’s the single detail I’d flag first to anyone assuming they have more runway than they do.

What the Grant and Bond Are Actually Worth

Assuming the age window is still open, the CDSG matches personal contributions at 300%, 200%, or 100%, depending on the beneficiary’s adjusted family net income, up to $3,500 a year and $70,000 over a lifetime. For the 2026 benefit year, families at or below an adjusted net income of $117,045 get the $3-for-$1 rate on the first $500 contributed and $2-for-$1 on the next $1,000, while families above that threshold get a flat $1-for-$1 match on the first $1,000, according to the CRA’s 2026 income matching rates bulletin.

The Canada Disability Savings Bond requires no personal contribution at all. A family with adjusted net income at or below $38,237 for 2026 gets the full $1,000 a year, phasing down to nothing once income crosses $58,523, up to a $20,000 lifetime maximum. Both figures are indexed annually, which is exactly why an old blog post citing a specific dollar threshold from a few years back is usually already out of date.

What Happens If DTC Eligibility Ends

A change that came out of Budget 2019 matters more than most families realize until it directly affects them. If a beneficiary’s DTC eligibility lapses, whether because their condition improved, they aged out of a temporary approval period, or the CRA simply didn’t renew it, the RDSP itself doesn’t automatically have to close. The plan can stay open, and if the beneficiary is later reapproved for the DTC, the account picks back up where it left off rather than starting over.

This matters most for conditions the CRA certifies for a fixed number of years rather than permanently, since a lapse used to force a full plan wind-down under the old rules, triggering repayment of grants and bonds received in the prior 10 years. Under the current rules, a temporary DTC gap no longer automatically forces that outcome, though the specific repayment consequences still depend on when the lapse happens and whether the holder makes withdrawals during it.

A Worked Example

Consider someone who was clearly eligible for the DTC starting in 2019, based on a condition that began that year, but didn’t get around to applying until 2026, at age 40. Once approved, they can ask the CRA to reassess up to 10 prior tax years through a T1 Adjustment Request, so the DTC approval effectively reaches back to 2019 rather than starting fresh in 2026, per the Taxpayers’ Ombudsperson’s own description of the retroactive adjustment process.

That backdating matters directly for the RDSP, because unused grant and bond entitlements from those earlier years can potentially be claimed through a 10-year carry-forward once the account is open and DTC-approved, subject to the same $10,500 annual grant cap and $11,000 annual bond cap that apply to carried-forward amounts. It’s not automatic money, and it depends heavily on income in each of those retroactive years, but it’s a meaningfully different outcome than assuming those six lost years are simply gone.

What to Do If You’re Not Sure You Qualify

Start with the DTC, not the RDSP, since nothing else on this page matters until that approval is in hand. If you’re unsure whether your or a family member’s condition would meet the functional criteria, the CRA’s self-assessment questionnaire in Guide RC4064 is a reasonable first pass before involving a doctor’s office, and it’s free. From there, Form T2201 needs a qualified medical practitioner (which can include a doctor, nurse practitioner, occupational therapist, physiotherapist, psychologist, audiologist, speech-language pathologist, or optometrist depending on the impairment) to complete Part B, describing function rather than diagnosis.

Once DTC approval comes through, opening the actual RDSP account is the comparatively easy part, and confirming your specific carry-forward grant and bond math with your chosen financial institution should happen in the same conversation as opening the account, not months later.

A Few More Questions Worth Answering

Does applying for the DTC automatically enroll someone in an RDSP? No. The DTC approval is a prerequisite, but the RDSP itself has to be opened separately at a financial institution, and grants and bonds still need to be applied for once the account exists.

What happens if a DTC application gets denied? You can still apply for an RDSP later if a future application succeeds, and a denial on one attempt doesn’t permanently disqualify someone. Many successful applications follow an earlier denial where the form simply didn’t describe the functional impact in enough detail the first time.

Can someone have more than one RDSP? No. A beneficiary can only have one RDSP open at any given time, though that single plan can have more than one plan holder listed on it simultaneously, and holders can change over the life of the plan.
