Ontario Child Benefit for Kinship Caregivers: Grandparent and Relative Guide

What the Ontario Child Benefit Is and Why Kinship Caregivers Miss It

The Ontario Child Benefit pays up to $1,759.92 per year — roughly $146.66 each month — per child under eighteen. It is income-tested based on the caregiver's Adjusted Family Net Income, with the full amount going to households at or below $26,865. Many grandparents and relatives raising a child never realise they qualify, because the OCB does not have its own application form. It piggybacks entirely on the Canada Child Benefit.

If you have already filed CRA Form RC66 and the Canada Revenue Agency recognises you as the child's primary caregiver, you are automatically assessed for the OCB. There is nothing extra to submit.

How the OCB Works for Relative Caregivers

The OCB is a provincial top-up administered by the CRA alongside the federal CCB. Both land in a single monthly deposit. Eligibility depends on three things:

1. You are the recognised primary caregiver — the CRA has accepted your Form RC66 and you receive the CCB
2. The child is under 18 and lives in Ontario
3. Your Adjusted Family Net Income falls within the benefit range (full benefit at or below $26,865; partial benefit phases out gradually above that)

No court order or CAS file is required to apply for CCB and OCB, but a formal foster placement has different benefit arrangements. For other arrangements, the CRA assesses primary care and control and household income when determining the benefits.

What It Pays in the 2026–2027 Benefit Year

The maximum OCB amount is $1,759.92 per year per child ($146.66/month). For many kinship caregivers — especially grandparents on OAS and GIS with modest reported income — the full amount applies. The OCB phases out gradually above the $26,865 threshold, so a caregiver above that amount may still receive a partial benefit.

The OCB benefit year runs July to June, calculated from the previous year's tax return. For July 2026 through June 2027, the CRA uses your 2025 T1 return.

The Transition Child Benefit Covers the Gap

CRA processing delays on a new RC66 application can stretch to several months. If you are receiving Ontario Works or ODSP in your own right during that wait, your municipal OW office should pay the Transition Child Benefit — up to $230 per month per child — to bridge the gap until OCB payments start flowing. Ask your caseworker specifically about the TCB; some offices do not volunteer it.

Once the OCB kicks in, the TCB adjusts downward or stops, depending on the OCB amount.

How OCB Stacks with TCA and CCB

For an eligible caregiver in an informal or Kinship Service arrangement, the OCB, CCB, and Temporary Care Assistance can stack. The rules differ for a formal foster placement:

A grandparent on a low income caring for one grandchild under six could receive over $1,100 per month in combined benefits — without a single dollar of their pension being assessed or reduced.

One Critical Step: File Your Tax Return Every Year

The CRA calculates both the CCB and OCB from your annual tax return. If you or your spouse do not file — even in a year with zero income — the CRA pauses benefit payments until it receives a return. This trips up grandparents who have not filed for years because they assumed their pension income was handled automatically through the T4A(OAS) slip. File every year, even if the return is straightforward.
