RDSP basics
What is the RDSP?
A Registered Disability Savings Plan is a long-term Canadian savings plan designed for people with disabilities. It can provide a tax-deferred place to build savings over time, with government grant and bond programs available when the beneficiary meets the relevant rules.
The Disability Tax Credit is an important connection point, but RDSP eligibility and grant or bond access can depend on several details. Family income, beneficiary age, prior contributions, and government program rules all matter.
Grant and bond basics
Understand matching before contributing
The Canada Disability Savings Grant is a matching program tied to eligible RDSP contributions. The Canada Disability Savings Bond is income-tested and may be available without a contribution in some cases.
The matching structure is tiered, so a larger contribution does not always create a proportionally larger grant estimate. Before adding money, it helps to understand which portion may be matched and which portion may simply use contribution room.
Carry-forward strategy
Unused grant room can make the math less obvious
Unused RDSP grant room can carry forward under program rules. That makes contribution planning more nuanced for families who opened a plan later, missed years, or have multiple years of possible room to estimate.
The RDSP Grant Optimizer can help model carry-forward years and compare contribution scenarios. The goal is to understand the matching estimate and contribution order, not to turn a calculator result into a recommendation.
Timing rules
Deadline urgency and the 10-year rule
Timing can matter because RDSP grants and bonds have age and carry-forward rules. Waiting may reduce available matching opportunity, especially when older unused room begins to fall outside the available window.
Rules can depend on age, eligibility, and prior contribution history. Treat this page as educational context and verify details against current CRA or ESDC guidance, or with a qualified professional who can review a specific situation.
RDSP Grant Optimizer
Estimate grant matching and carry-forward scenarios before you add money.
The calculator helps model grant matching estimates, carry-forward years, contribution order, and age-window timing from the values you enter. It is designed for education and scenario comparison, not a recommendation.
- Estimate annual grant and bond amounts.
- Test unused carry-forward room assumptions.
- Compare contribution scenarios at a high level.
- Review timing pressure around the grant window.
