A family watches a Registered Disability Savings Plan (RDSP) grow for years, mostly on the strength of the Canada Disability Savings Grant and Canada Disability Savings Bond, and reasonably assumes that once the beneficiary actually needs the money, they can simply withdraw what they need. Sometimes that’s exactly how it works. Sometimes it isn’t, because an RDSP where government money outweighs what the family itself contributed comes with a legal ceiling on how much can come out in a single year, calculated by a formula most people never encounter until they try to make a withdrawal larger than expected.
Two kinds of payments come out of an RDSP. A Disability Assistance Payment (DAP) is a one-time withdrawal that can be requested whenever the holder decides. A Lifetime Disability Assistance Payment (LDAP) is a recurring payment that, once started, has to continue at least annually for as long as the beneficiary lives or the plan exists, and has to begin no later than the end of the year the beneficiary turns 60, one of several age-based deadlines built into the program. Whether either of these gets capped, and by how much, depends entirely on where the money in the account actually came from.
The Test That Determines How Much You Can Take
At the start of every calendar year, an RDSP gets classified based on a simple comparison. If the total Canada Disability Savings Grant and Canada Disability Savings Bond money paid into any of the beneficiary’s RDSPs over the years is greater than the total private contributions made to those plans, the RDSP is a Primarily Government Assisted Plan (PGAP) for that year. If private contributions outweigh the government money instead, it’s a non-PGAP, and withdrawals face far fewer restrictions. Since the government grant money frequently outpaces what a family personally contributes, especially for lower-income beneficiaries who qualify for the strongest matching, a large share of RDSPs end up classified as PGAPs at some point, particularly in their earlier years.
The Formula Behind the Ceiling
In a PGAP year, combined DAP and LDAP withdrawals for that year can’t exceed whichever is larger, a set formula result or 10 percent of the plan’s fair market value at the start of the year. The formula itself divides the plan’s value at the beginning of the year by the number of years remaining until the beneficiary turns 83, with that divisor locked at 3 once the beneficiary reaches 80. A larger account balance produces a larger permitted withdrawal under this formula, and a beneficiary closer to 83 sees the divisor shrink, which pushes the maximum higher as retirement age approaches, a calculation worth running through an RDSP calculator rather than estimating by hand. None of this applies at all to a non-PGAP plan, where a beneficiary or holder can generally request a withdrawal without running into this ceiling in the first place.
Why the Beneficiary Sometimes Has the Final Say
There’s a specific age window where this rule shifts control toward the beneficiary directly. If the plan is a PGAP and the beneficiary is between 27 and 58 years old inclusive, the beneficiary has the right to direct that a disability assistance payment be made, regardless of what the plan holder might otherwise prefer. This exists partly to make sure an adult beneficiary who’s contractually capable isn’t left waiting on someone else’s decision about their own money, and partly to keep the repayment consequences of any withdrawal properly connected to an actual, deliberate request rather than something that happens by default.
The Floor That Protects the Government’s Money
Even a modest, well within the PGAP formula, withdrawal isn’t automatically allowed if it would push the plan below a specific line. An RDSP can’t pay out a DAP if doing so would drop the plan’s value under the Assistance Holdback Amount, meaning the total grants and bonds paid into the plan over the preceding 10 years that haven’t already been repaid. This exists for a straightforward reason. If a withdrawal later triggers a repayment obligation under the 10-year rule, the plan needs to still hold enough money to actually cover it. A family focused only on the PGAP formula ceiling can still run into this second, quieter constraint if the account’s overall value is thin relative to how much grant and bond money has landed in it recently.
When the Ceiling Disappears Entirely
None of these limits apply if a medical practitioner certifies that the beneficiary isn’t expected to live longer than five years, and that certification is filed with the RDSP issuer as a specified year election. Once that election is in place, withdrawals in the certification year and every year after can proceed without the PGAP formula ceiling and without triggering repayment of the Assistance Holdback Amount under the ordinary 10-year rule, since the point of the restriction, protecting long-term savings, no longer serves the beneficiary’s actual circumstances. The same removal of restrictions applies when a plan is being wound down because the beneficiary has lost Disability Tax Credit eligibility and the holder is closing the account, and when the beneficiary has died and remaining plan assets are being paid out.
What the Money Can Actually Be Spent On
Once a DAP or LDAP leaves the RDSP, there’s no restriction on how it gets used, unlike the education-specific rules that govern an RESP withdrawal. The portion made up of contributions comes out tax-free, since that money was never deducted from income in the first place, while the portion made up of grants, bonds, rolled-over amounts, and investment growth counts as taxable income to the beneficiary in the year it’s paid. Not every RDSP provider offers a standalone lump-sum DAP separate from LDAP payments, so it’s worth confirming directly with the specific institution holding the plan whether that flexibility actually exists before assuming it does.
Checking Which Rules Apply to You
Ask your RDSP provider directly whether the plan is currently classified as a PGAP or a non-PGAP, since that single distinction determines almost everything else about how much can come out this year. If it’s a PGAP, request the actual formula calculation rather than estimating it yourself, since the fair market value used in the calculation is measured at a specific point each year and changes as the account grows. And if a terminal diagnosis is part of the picture, ask specifically about the specified year election, since it removes restrictions that would otherwise apply and isn’t something that happens automatically without the paperwork being filed.
