CDB is a tax-free benefit for families who care for a child (under 18) with a severe and prolonged impairment in physical or mental functions. To be eligible, a child must qualify for the disability amount (Form T2201, Disability Tax Credit Certificate). CDB is paid monthly to Canada Child Tax Benefit (CCTB) eligible individuals and as a supplement to the Children's Special Allowances (CSA).
Additional information and application forms are available on the Canada Revenue Agency Web site at http://www.cra-arc.gc.ca/bnfts/dsblty-eng.html.
