Currently, the Canada Emergency Response Benefit (CERB) and the newly instated Canada Recovery Benefits (CRB) will not have any affect your CPP / OAS or CPP Disability benefits. CERB and CRB are not considered as employment or self-employed income, therefore you do not have to report these benefits under your CPP Disability benefit.
However, you should consult your regional support program to find out if CERB/CRB has any affect to your provincial benefits.
CERB/CRB payments will have to be reported to CRA in your 2020 income tax. You will receive a T4A from Canada Revenue Agency.
There are no update at the moment if CERB or CRB will have any effect toward your income tested federal programs, e.g GIS or Allowance.
