The RDSP link
For many people, the most valuable consequence of DTC approval is not the tax credit itself but what approval unlocks: the Registered Disability Savings Plan, or RDSP. DTC approval is a requirement for opening an RDSP. Without an approved certificate, a plan cannot be opened for a person, no matter how much family members wish to save for them. With approval, the plan can be opened, and government grants and bonds can begin to flow into it.
What an RDSP is, in brief
An RDSP is a long-term savings plan designed to help a person with a disability save for the future, with government help added on top of private contributions. The beneficiary is the person approved for the DTC. A holder, who may be the beneficiary or, in many cases, a parent or legal representative, opens and manages the plan with a financial institution that offers RDSPs. Contributions are not tax-deductible, but investment growth inside the plan is tax-deferred, and withdrawals are taxed in the beneficiary's hands when they are taken out, usually at a time when the beneficiary's income is lower.
The government help: grants and bonds
Each year, the Government of Canada may pay up to $3,500 in Canada Disability Savings Grants, which match private contributions at rates up to 300% depending on family income, and up to $1,000 in Canada Disability Savings Bonds for people with low or modest incomes, with no personal contribution required. Over a lifetime, grants can total up to $70,000 and bonds up to $20,000 per beneficiary. Grants and bonds are payable until 31 December of the year the beneficiary turns 49, and unused grant and bond entitlements can be caught up for up to the previous 10 DTC-approved years. Family income decides the grant and bond rates, which is why filing tax returns matters even in years when no tax is owed.
Who can be a beneficiary
To open an RDSP, the beneficiary must be a Canadian resident, must have a Social Insurance Number, must be approved for the DTC, and must be under 60 when the plan is established, in practice before 31 December of the year the beneficiary turns 59. The steps are: get DTC approval first, choose a financial institution that offers the plan, open the plan with that institution, and keep filing tax returns so that grant and bond entitlements can be calculated. Opening a plan is a separate decision from applying for the DTC, and it should be made with advice about the plan's withdrawal rules, which include a holding period: grants and bonds generally must remain in the plan for 10 years, or they may have to be repaid on withdrawal.
If DTC approval is later lost
If a beneficiary's DTC approval ends, an existing RDSP is not automatically closed on the spot, but new contributions cannot be made and new grants and bonds cannot be paid into the plan while the beneficiary is not DTC-approved. That is one more reason to track the approval period on the notice of determination and to reapply before it expires where the impairment continues. Losing approval temporarily should be treated as urgent, because every year without approval is a year of grant and bond entitlement that cannot simply be recovered later without limit.
Why this page is on a tax-credit site
The DTC and the RDSP are different programs, run by different parts of the government, but the DTC certificate is the key that opens the RDSP door. A family that delays a DTC application is usually also delaying RDSP grants and bonds, and the 10-year catch-up limit means delay has a real cost. Apply for the certificate first, and treat the RDSP as the second step, not as an afterthought.
