Child disability benefit

The child disability benefit (CDB) is a tax-free benefit for families who care for a child under age 18 who is eligible for the disability tax credit.

A child is eligible for the disability tax credit when a medical practitioner certifies, on Form T2201, Disability Tax Credit Certificate, that the child has a severe and prolonged impairment in physical or mental functions, and the Canada Revenue Agency (CRA) approves the form.

The CDB is paid monthly to the Canada child benefit (CCB) eligible individuals and also as a supplement to the children's special allowances (CSA).
