The Child Disability Benefit is extra tax-free money added to the Canada Child Benefit for a child with a disability. Your child must be approved for the Disability Tax Credit.

How much

For July 2026–June 2027: up to $3,480 per year ($290/month) per eligible child. It is reduced when adjusted family net income is over $82,847 (3.2% for one eligible child, 5.7% for two or more).
