Why this decision matters
The Registered Disability Savings Plan exists to build long-term financial security for a person with a severe and prolonged impairment — the gateway is eligibility for the Disability Tax Credit. Once open, the plan can receive up to $200,000 of lifetime contributions, and, far more importantly, government money on a scale no other plan approaches.
The Canada Disability Savings Grant matches contributions at up to 300% depending on family income — as much as $3,500 of grant in a year, to a $70,000 lifetime maximum. The Canada Disability Savings Bond adds up to $1,000 per year (lifetime $20,000) for lower-income beneficiaries with no contribution required.
The central idea
On the first $500 contributed, lower-income families can receive $1,500 of grant. No other plan multiplies savings this way.
The matching structure means even modest contributions transform: at the highest match rates, $1,500 contributed can attract $3,500 of grant in a single year. Unused grant and bond entitlements carry forward up to ten years, so families who discover the plan late can catch up substantially. Grants and bonds are payable until the end of the year the beneficiary turns 49, which makes the years before that birthday genuinely valuable.
The plan's discipline lies in its holdback rule: grants and bonds received in the ten years before a withdrawal may have to be repaid if funds are taken early — the RDSP is engineered for the long hold, with regular Lifetime Disability Assistance Payments typically beginning by age 60. Crucially, RDSP assets and payments are generally exempt from provincial disability benefit calculations, so the plan builds security without dismantling existing supports. Growth, grants, and bonds are taxed to the beneficiary when withdrawn — usually at low rates — while original contributions come out tax-free.
