Important: The CDB is designed to supplement, not replace, existing provincial disability programs. Provinces have agreed not to claw back provincial benefits dollar-for-dollar.

Canada Disability Benefit and provincial social assistance
A key concern for many applicants is whether receiving the CDB will reduce provincial benefits (like ODSP or AISH). The CDB was designed to be a top-up, not a replacement — but provincial clawback rules vary:
Province
Treatment of CDB in social assistance
Ontario (ODSP)
CDB is currently exempt from ODSP income calculation
Alberta (AISH)
CDB treatment under review — confirm with AISH
BC (PWD)
CDB treatment under review — confirm with provincial ministry
Other provinces
Varies — contact your provincial social assistance office
Because the CDB is new (launched July 2025), provinces are still finalizing their policies. Check directly with your provincial disability program before assuming CDB will or will not affect your provincial support.
How to maximize CDB alongside other benefits
Strategy
Benefit
Apply for DTC before applying for CDB
DTC is required for CDB; applying early avoids delays
File taxes every year
CDB requires annual tax filing; failure to file stops payments
TFSA contributions
TFSA withdrawals don’t count as income, allowing you to save without reducing CDB
RDSP contributions
RDSP is another key benefit unlocked by the DTC — contributes to long-term savings tax-free
Track provincial rules
Some provinces exempt CDB; others may reduce their benefits — know your province’s rules
