Is CPP disability benefit taxable income if I receive it in Ontario?

Yes. Canada Pension Plan disability benefits are taxable income at the federal and provincial level. CRA issues a T4A(P) slip each year showing the amount of CPP disability benefits you received. This amount is included on Line 11400 of your T1 return and is added to your other income before credits are applied.

Because CPP disability benefits are taxable, you may be able to offset some of the resulting tax with non-refundable credits. If you have an approved Disability Tax Credit, you can claim the DTC on your return. Other credits — the Canada Caregiver Credit, medical expense credit, and the basic personal amount — also reduce the tax payable on your benefit income.

Recipients whose total income is low enough may also qualify for the Guaranteed Income Supplement (GIS) if they receive Old Age Security — though CPP disability converts to a CPP retirement pension at 65, which then interacts differently with GIS eligibility. Provincial supports like the Ontario Disability Support Program (ODSP) are separate and have their own income calculations that may treat CPP disability income differently than the federal tax system does.
